Important facts
- Partograph is plotted ONLY in the active phase (cervix ≥4 cm); latent phase is documented but not graphed on the action grid.
- FHR recorded every 30 minutes in active first stage; every 5–15 minutes in second stage; normal range = 110–160 bpm.
- Cervical dilatation ('X') examined every 4 hours in active phase (avoid over-examination; risk of infection).
- Descent of fetal head ('O') measured in fifths palpable ABOVE the pelvic brim: 5/5 (high) → 0/5 (engaged/deep).
- Contractions recorded every 30 minutes; good labor = 3–5 per 10 minutes, each lasting ≥40 seconds (solid stippling on chart).
- Maternal pulse every 30 minutes; BP every 4 hours; temperature every 2–4 hours; urine with each void.
- The TRANSFER ZONE (gap between alert and action lines) is the safety buffer—gives the midwife time to move the mother to a CEmONC facility BEFORE crisis.
- Expected minimum cervical dilatation in active phase = 1 cm/hour (classic partograph standard for MLE).
- Prolonged latent phase = >8 hours with no progression to active phase → reassess and refer.
- If no progress within 2 hours in active phase = arrest of dilatation → refer immediately.
Key definitions
Partograph (Partogram)
Example
The 'X' (cervical dilatation) drifting right of the alert line signals slow progress requiring referral.
A graphic, real-time single-page record of labor progress that plots fetal condition, progress of labor, and maternal condition against time—enabling early detection of obstructed/prolonged labor.
Active Phase of Labor
Example
Plotting on the partograph grid and alert/action line interpretation apply ONLY in the active phase (≥4 cm).
First stage labor starting at 4 cm cervical dilatation with regular contractions; expected minimum progress = 1 cm/hour dilatation.
Alert Line
Example
If cervical dilatation 'X' crosses RIGHT of the alert line, labor is slower than expected → arrange early referral.
Diagonal line on the partograph running from 4 cm to 10 cm at a slope of 1 cm/hour—represents the slowest-normal labor rate.
Action Line
Example
Dilatation at the action line = significantly obstructed labor; mother MUST already be in a comprehensive facility.
Diagonal line drawn 4 hours to the RIGHT of (and parallel to) the alert line—reaching it mandates immediate decisive intervention in a CEmONC facility.
Diagrams to know
- The partograph layout (three sections: fetal condition, progress of labor, maternal condition) with time axis on X, dilatation on Y.
- Alert line vs action line positions—where the 4 cm start point and 1 cm/hour slope are drawn.
- Example of 'X' dilatation plotted at different times: on alert line (normal), right of alert line (slow), at action line (obstructed).

Important facts
- 'X' = cervical dilatation (in cm, 0–10); 'O' = descent of fetal head (in fifths above brim).
- Amniotic fluid 'M' or 'B' = possible fetal compromise; requires closer monitoring and possible referral if combined with abnormal FHR.
- Moulding increases with prolonged labor/obstruction; +++ is a RED FLAG especially if dilatation is slow.
- Contraction shading must show BOTH frequency (number) AND duration (length of bar) every 30 minutes.
- Never skip recording maternal pulse (every 30 min), BP (every 4 hours), temperature (every 2–4 hours) — they reveal maternal distress.
- Urine assessment (volume, protein, acetone/ketones) is part of the partograph and signals dehydration, infection, or pre-eclampsia.
- FHR recorded AFTER a contraction (not during) to detect any abnormal dips or recovery.
- If membranes rupture DURING labor, record the time, character (C/M/B/A), and continue FHR monitoring closely.
Key definitions
Cervical Dilatation Symbol
Example
At 9 AM, cervix 5 cm; plot 'X' on the 5 cm line at the 9 AM column.
'X' plotted on the partograph grid at the appropriate cm and hour—direct measurement during vaginal examination.
Descent of Fetal Head Symbol
Example
5/5 palpable (head high); 0/5 palpable (head deeply engaged); descent line shows downward progress as 'O' moves down.
'O' plotted on descent line, measured in fifths of the fetal head palpable ABOVE the pelvic brim (5/5 → 0/5).
Amniotic Fluid Codes
Example
If ruptured membranes with green-stained fluid, record 'M' = increased risk of fetal distress.
Single letter recorded with FHR: I (intact), C (clear), M (meconium-stained), B (blood-stained), A (absent/dry).
Moulding Grade
Example
Grade +++ with slow cervical dilatation = cephalopelvic disproportion; urgent referral needed.
Overlap of fetal skull bones graded 0 (separated), + (touching), ++ (overlapping, reducible), +++ (overlapping, non-reducible).
Contraction Recording (Shading)
Example
Solid stippling over 3 contractions = good labor; light stippling = inadequate contractions → may need augmentation or reassessment.
Light stippling = <20 sec (weak); diagonal lines = 20–40 sec (moderate); solid = >40 sec (strong) per 10-minute interval.
Diagrams to know
- The three columns of the partograph top section: FHR (with normal range 110–160 bpm), amniotic fluid code (I/C/M/B/A), and moulding grade (0/+/++/+++).
- The contraction recording section—how to fill in the 10-minute boxes with appropriate shading pattern.
- The descent line: how 'O' moves downward from 5/5 to 0/5 as labor progresses.
Interpreting the Alert & Action Lines
Formulas
Alert Line Slope = 1 cm dilatation per 1 hour
Meaning
Cervical dilatation expected to increase by at least 1 cm for every 1 hour of active labor (from 4 cm onwards).
Watch out
Plotting 'X' RIGHT of alert line = slow labor (protraction); does NOT yet mean the labor must be managed operatively, but it IS the trigger to REFER/ARRANGE TRANSFER while the mother is still stable.
When to use
To determine if the plotted 'X' is on, left of, or right of the normal-progress line.
Action Line Position = Alert Line + 4 hours horizontally (parallel)
Meaning
The action line is drawn 4 hours to the right of the alert line, running parallel to it (same 1 cm/hour slope).
Watch out
Reaching the action line = the mother MUST ALREADY BE in a facility with surgical capability; do not delay or try to manage further at a health center. If she reaches the action line, an error in earlier transfer decision has occurred.
When to use
To identify the point beyond which labor is significantly obstructed and requires immediate intervention in a CEmONC facility.

Important facts
- The alert line is drawn from 4 cm at hour 0 (time of admission to active phase) to 10 cm at the expected time of full dilatation (6 hours for a primigravida, ~3 hours for multigravida).
- Both alert and action lines have the SAME SLOPE (1 cm/hour); the action line is simply shifted 4 hours to the right.
- Plotting the cervical dilatation 'X' at each examination is THE KEY—it immediately shows whether labor is on track or drifting right.
- Crossing the alert line is NOT an emergency; it is a WARNING to REFER and TRANSFER while the situation is still controlled.
- Crossing the action line IS a late-stage signal; ideally, the mother should already be in the referral facility before reaching it.
- If multiple 'X' marks are connected by a line, the slope of that line directly shows the actual rate of dilatation compared to the alert/action lines.
- A steep slope (many 'X' marks moving up quickly and staying left) = rapid labor = normal, reassuring.
- A flat or slowly rising slope (moving right over time) = slow labor = protraction/obstruction risk.
Key definitions
Left/On the Alert Line
Example
At 10 AM (2 hours into active-phase plotting), cervix is 6 cm (expected 1 cm/hr from 4 cm start) → plotted on the line = normal.
Cervical dilatation plotted to the left of or on the alert line indicates normal (or faster-than-minimum) labor progress.
Right of the Alert Line (Protraction)
Example
At 10 AM (2 hours later), cervix is only 5 cm (should be ~6 cm) → 'X' is right of alert line; reassess and arrange early referral.
Cervical dilatation slower than 1 cm/hour; labor progress is slower than expected but not yet obstructed.
At/Past the Action Line (Obstructed Labor)
Example
By 2 PM, cervix is still 6 cm (4 hours after a 2 cm dilatation) → reaching action line; mother MUST be in a CEmONC facility NOW.
Cervical dilatation has reached the action line; labor is significantly obstructed/prolonged and requires immediate definitive management.
Transfer Zone
Example
Recognizing crossing the alert line at 10 AM gives the midwife 4 hours to arrange transport, prepare the mother, and communicate with the receiving facility.
The 4-hour space between the alert and action lines—the safety buffer allowing time for organized, safe transfer to a CEmONC facility BEFORE labor becomes an emergency.
Diagrams to know
- Alert line drawn from 4 cm to 10 cm at a 1 cm/hour diagonal slope.
- Action line drawn 4 hours horizontally to the right of the alert line, parallel to it.
- Example plots: 'X' marks staying left of alert line (normal), drifting right (slow), reaching action line (obstructed).
- Transfer zone shading between alert and action lines to show the safety buffer.

Symbol
FHR-Abnormal
Quantity
Fetal Heart Rate (Tachycardia Threshold)
Important facts
- FHR should be recorded IMMEDIATELY AFTER a contraction, not during or before, to detect abnormal recovery.
- Normal FHR = 110–160 bpm; <110 (bradycardia) or >160 (tachycardia) are both RED FLAGS.
- Meconium (code 'M') in a slow labor (right of alert line) increases the risk of fetal distress → refer earlier rather than wait for other signs.
- Meconium alone, with normal FHR and good progress, is less urgent but still requires close monitoring.
- Blood-stained liquor (code 'B') is rare in normal labor and warrants immediate investigation for placental abruption or infection.
- Absent liquor (code 'A') indicates severe dehydration (dry labor); accompanied by meconium = dried meconium = very prolonged labor.
- If FHR drops below 110 or rises above 160, perform a full fetal assessment: confirm lie/presentation, check cord, rule out placental abruption.
- First response to abnormal FHR: change maternal position to LEFT LATERAL (improves placental perfusion), give IV fluids, increase oxygen if available.
- Document the exact time FHR abnormality begins; this timing guides referral urgency and affects decision-making at the receiving facility.
Key definitions
Fetal Distress (Abnormal FHR)
Example
FHR 90 bpm or repeatedly dipping to 80 bpm after contractions → change maternal position (left lateral), give fluids, REFER immediately.
FHR <110 bpm or >160 bpm, persistent drops after contractions, or irregular rhythm—indicates fetal hypoxia or other compromise.
Meconium-Stained Liquor
Example
If 'M' code AND FHR <110, risk of fetal distress is HIGH → refer to facility with neonatal resuscitation capability.
Amniotic fluid stained green (meconium passage) = possible fetal compromise, especially if combined with abnormal FHR or slow labor.
Blood-Stained Liquor
Example
If 'B' code with vaginal bleeding or rising maternal pulse/temperature → refer emergently; risk of fetal death and maternal hemorrhage.
Amniotic fluid stained with blood (code 'B') = may indicate placental abruption, chorioamnionitis, or other serious maternal/fetal problem.
Diagrams to know
- Normal FHR tracing on partograph (consistent 110–160 bpm) vs abnormal (dips, bradycardia, tachycardia).
- Combination of fetal danger signs: meconium + abnormal FHR + slow progress = highest urgency for referral.

Important facts
- Maternal pulse recorded every 30 minutes; rising pulse (>100 bpm) even without other signs warrants IV fluids and reassessment.
- Blood pressure recorded every 4 hours in low-risk labor; if ≥140/90, check again and test urine for protein.
- Temperature recorded every 2–4 hours; single reading >38°C or rising trend requires investigation (ruptured membranes? infection? prolonged labor?).
- Pre-eclampsia warning signs: BP ≥140/90 + proteinuria + headache/epigastric pain/visual disturbance = REFER to facility with capability for magnesium sulfate, delivery.
- Dehydration (ketones in urine, tachycardia, falling urine output) is cumulative in prolonged labor; IV fluids + reassessment + possible referral.
- Vaginal bleeding during labor (not bloody show): if >100 mL, investigate for placental abruption or uterine rupture; REFER emergently.
- Signs of uterine rupture: sudden, severe pain; loss of contractions; vaginal bleeding; maternal shock; maternal tachycardia; fetal bradycardia.
- Signs of uterine tetany (over-stimulation): tonic contraction lasting >60 seconds, rising uterine tone, maternal pain, fetal bradycardia → stop oxytocin, refer.
Key definitions
Maternal Tachycardia
Example
Pulse rises from 80 to 110 bpm over 2 hours in prolonged labor → dehydration, exhaustion, or impending obstetric emergency.
Maternal pulse >100 bpm (especially rising pulse) = sign of dehydration, infection, hemorrhage, or maternal distress from prolonged labor.
Hypertension in Labor
Example
BP 145/95, urine protein +2, headache → eclampsia risk; refer IMMEDIATELY to facility for magnesium sulfate, delivery planning.
Blood pressure ≥140/90 mmHg with proteinuria and/or clinical signs (headache, epigastric pain, visual disturbance) = pre-eclampsia.
Maternal Fever
Example
Temperature 38.5°C + prolonged rupture of membranes + foul liquor = chorioamnionitis; refer for IV antibiotics and delivery.
Temperature >38°C (or rising) in labor = sign of chorioamnionitis or other maternal infection; increases fetal and maternal risk.
Urine Abnormalities
Example
Protein +2, specific gravity high, minimal urine output → dehydration + possible pre-eclampsia; IV fluids + referral needed.
Proteinuria (protein ≥+1), ketonuria (acetone positive), or scanty urine (<100 mL per void) = pre-eclampsia, dehydration, or acute kidney injury.
Diagrams to know
- Maternal vital signs section of partograph: pulse every 30 min, BP every 4 hours, temperature every 2–4 hours, urine at each void.
- Recognition of pre-eclampsia cluster: hypertension + proteinuria + neurological/abdominal symptoms.
- Red flags for serious maternal complications: rising pulse + rising temperature + slow labor = infection/obstruction cluster.

Arrest of Descent (Second Stage)
Important facts
- Prolonged latent phase (>8 hours) often resolves with false labor recognition, rest, and hydration; some women enter active phase spontaneously, others require augmentation or referral.
- Protraction (slow active phase) is the MOST COMMON abnormality detected on the partograph; it is also the MOST FORGIVING—crossing the alert line is the TIME TO REFER, not a crisis.
- Arrest of dilatation (≥2 hours no change) is MORE SERIOUS than protraction; indicates mechanical obstruction or exhaustion; refer urgently.
- Excessive moulding (+++) accompanying slow/arrested labor = CEPHALOPELVIC DISPROPORTION (pelvis too small for the fetal head); surgical delivery likely needed.
- Obstructed labor is a MEDICAL EMERGENCY: risk of uterine rupture (maternal death), fetal death, prolonged fistula, and serious maternal morbidity.
- A tonic (retracted, rigid) uterus with little relaxation between contractions = tetanic contractions = obstructed labor until proven otherwise; refer emergently.
- The presence of a Bandl's ring (visible ridge on the abdomen marking the junction of stretched lower uterine segment and upper uterine cavity) = severe obstruction; uterine rupture imminent.
- Maternal exhaustion (cannot push, semiconscious, vital signs unstable) in second stage = refer; may need assisted delivery or cesarean.
Key definitions
Prolonged Latent Phase
Example
Admitted at 0 cm, 12 hours later still at 3 cm, contractions weak → assess contraction quality; if still inadequate after reassurance, refer.
Latent-phase labor (0–4 cm) lasting >8 hours with no progression to active phase; indicates inadequate contractions or cephalopelvic disproportion.
Protraction (Prolonged Active Phase)
Example
Cervix reaches 5 cm at 2 hours, then only 6 cm at 4 hours (0.5 cm/hr) → drifting right of alert line; reassess and refer while stable.
Cervical dilatation progressing slower than 1 cm/hour during the active phase; the 'X' drifts right of the alert line.
Arrest of Dilatation
Example
Cervix 7 cm for 2 hours, no further progress, contractions strong → arrest of dilatation; refer IMMEDIATELY to CEmONC facility.
No cervical change for ≥2 hours during active labor despite adequate contractions; indicates true cephalopelvic disproportion or obstructed labor.
Arrest of Descent
Example
Fully dilated for 1 hour, head still 2/5 palpable, strong pushing contractions → arrest of descent; refer for assisted delivery or cesarean.
Fetal head fails to descend despite strong contractions and full cervical dilatation in the second stage; indicates cephalopelvic disproportion.
Obstructed Labor
Example
Cervix right of action line, moulding +++, maternal pulse 120, FHR 100 → obstructed labor; EMERGENCY referral for cesarean.
Labor where the fetus cannot pass through the pelvis despite strong contractions; presents with slow/arrested dilatation, excessive moulding (+++ grade), signs of maternal/fetal distress.
Diagrams to know
- Graphical comparison: X marks plotted on alert line (normal), drifting right (protraction), arrested (arrest of dilatation), reaching action line (obstructed).
- Moulding progression: 0 → + → ++ → +++ correlated with cervical dilatation rate—+++ with slow dilatation = CPD.
- Second-stage partograph: 'O' descent marks showing downward progress; arrest of 'O' = cephalopelvic disproportion.

Important facts
- The partograph is DESIGNED to catch problems early—crossing the alert line is the TRIGGER for transfer, not the action line.
- Waiting until the action line is reached = waiting too long; the mother should already be in the referral facility being evaluated/managed.
- Safe referral includes: RECOGNIZE the problem → REFER early → RESUSCITATE/STABILIZE → RECORDS (complete referral form + partograph) → RIDE (safe transport) → RING AHEAD (call the facility).
- Indications for referral VISIBLE ON THE PARTOGRAPH: cervical dilatation crossing alert line, fetal distress (abnormal FHR, meconium), malpresentation, hemorrhage, pre-eclampsia signs.
- Indications for referral NOT always on partograph but important: previous cesarean, multiple pregnancy, breech presentation, severe anemia, diabetes, HIV/TB, mental health crisis.
- At the ACTION LINE or with signs of obstructed labor (tonic uterus, excessive moulding, severe maternal/fetal distress): referral is EMERGENT; treat for shock if needed.
- Referral form must include: reason for referral, maternal vital signs, partograph, FHR trends, urine/BP abnormalities, progress of labor, any treatments given, escort details.
- The midwife's role does NOT end at referral; accompany the mother if possible, give a handoff report, and follow up to learn the outcome.
Key definitions
Referral (in Midwifery Context)
Example
Partograph shows crossing the alert line; midwife at RHU arranges immediate transport to the nearest BEmONC or referral hospital.
The act of recognizing a condition beyond the scope of midwifery practice at a lower level and arranging safe transfer to a facility with appropriate resources (BEmONC or CEmONC).
BEmONC (Basic Emergency Obstetric and Newborn Care)
Example
BEmONC: IV antibiotics, oxytocin, magnesium sulfate, manual removal of placenta, assisted vaginal delivery with vacuum/forceps, neonatal resuscitation.
A facility (e.g., barangay health station, rural health unit) capable of managing normal labor and basic complications; does NOT include cesarean section.
CEmONC (Comprehensive Emergency Obstetric and Newborn Care)
Example
CEmONC: cesarean delivery, hysterectomy, laparotomy, anesthesia, ICU care, blood banking.
A facility (hospital with operating room) capable of all BEmONC functions PLUS cesarean section, blood transfusion, and complex neonatal/maternal resuscitation.
Alert-Line Crossing → Early Referral
Example
At 10 AM, cervix at alert line crossing; by 11 AM mother is stable and on transport to the referral hospital; crisis averted.
Recognition of slow labor (protraction) early enough to arrange organized, calm transfer to a CEmONC facility BEFORE an emergency develops.
Diagrams to know
- The '5 Rs' of safe referral: Recognize, Refer, Resuscitate, Records, Ride (+ Ring).
- Pyramid of care: home/community (normal birth) → health center/BEmONC (complications needing basic intervention) → CEmONC (obstructed labor, emergency surgery).
- Partograph-to-referral decision tree: alert line crossed? YES → refer to CEmONC. Fetal distress? YES → refer to CEmONC. Obstructed labor signs? YES → EMERGENT CEmONC.
Must remember
- The partograph MUST be plotted ONLY in the active phase (≥4 cm dilatation); latent phase is noted but NOT graphed on the alert/action lines.
- Cervical dilatation is plotted with 'X'; fetal head descent is plotted with 'O' (in fifths palpable ABOVE the pelvic brim, 5/5 → 0/5 = descending).
- Normal FHR = 110–160 bpm recorded every 30 minutes in active first stage; good labor = 3–5 contractions per 10 minutes each lasting ≥40 seconds.
- The ALERT LINE runs from 4 cm to 10 cm at 1 cm/hour slope. Plotting 'X' RIGHT of it = slow labor (protraction) = TRIGGER FOR EARLY REFERRAL to CEmONC.
- The ACTION LINE is 4 hours to the right of the alert line, parallel to it. Reaching it = significantly obstructed labor = mother MUST ALREADY BE in CEmONC facility (late trigger).
- The 4-hour space between alert and action lines is the TRANSFER ZONE—the safety buffer allowing organized, calm transfer to a CEmONC facility before crisis develops.
- Refer for crossing the alert line (early, stable referral); certainly refer if reaching the action line, if obstructed labor signs appear (tonic uterus, +++ moulding, abnormal FHR, maternal tachycardia/fever).
- Amniotic fluid codes: I (intact), C (clear), M (meconium-stained = possible fetal distress), B (blood-stained = abruption/infection risk), A (absent/dry = very prolonged labor).
- Increasing moulding (especially +++ = non-reducible overlapping) with slow/arrested cervical dilatation = CEPHALOPELVIC DISPROPORTION (pelvis too small for fetal head); emergency referral needed.
- The midwife's role is to RECOGNIZE problems early using the partograph and REFER promptly while the mother is still stable—NOT to manage obstructed labor beyond the scope of midwifery at a community/health-center level.
Last minute tips
- EXAM TRAP: Students often confuse the alert line SLOPE (1 cm/hour) with the action line slope. Remember: SAME SLOPE, different position. Action line is simply the alert line shifted 4 hours to the RIGHT.
- CRITICAL MINDSET: Crossing the alert line is NOT a crisis—it's a WARNING to organize referral calmly. Waiting until the action line is reached = waiting too long. The exam will test whether you understand this distinction.
- MLE GOLD STANDARD: Know the 'X' and 'O' symbols by heart. The examiner may ask you to plot or interpret a partially completed partograph; you must instantly recognize which symbol shows dilatation ('X') and which shows descent ('O').
- DANGER-SIGN CLUSTER: Pre-eclampsia = BP ≥140/90 + proteinuria + headache/epigastric pain/visual symptoms. Any ONE sign (e.g., high BP alone) is NOT sufficient; look for the cluster. Exam questions often give mixed information; don't over-diagnose.
- REFERRAL DECISION: The partograph is designed to turn a vague worry ('labor seems slow') into a DEFENDABLE, TIMELY DECISION ('crossing alert line → organize referral now'). Practice explaining WHY each danger sign requires referral—this clinical reasoning is what the MLE tests.
Comparison tables
Alert Line vs Action Line — Quick Comparison
| Feature | Alert Line | Action Line |
|---|---|---|
| Position on Partograph | Starts at 4 cm dilatation at hour 0 of active phase | 4 hours to the RIGHT of alert line, parallel to it |
| Slope | 1 cm dilatation per 1 hour | 1 cm dilatation per 1 hour (same slope, shifted right) |
| Meaning of Reaching It | Slow labor (protraction); progress slower than expected minimum | Significantly obstructed labor; labor must not continue without full assessment/intervention |
| Typical Referral Decision | Arrange early referral to CEmONC while mother is stable and in active labor | Mother should ALREADY BE in CEmONC being evaluated; if reached, indicates delayed referral error |
| Maternal Status at Crossing | Usually stable; vital signs normal; alert and cooperative | May show signs of exhaustion, dehydration, infection, or maternal/fetal distress |
| Risk of Complication | Moderate; time to assess and organize referral | HIGH; risk of uterine rupture, fistula, fetal death, maternal sepsis |
| Safety Buffer (Transfer Zone) | Between alert and action lines = 4 hours for organized transfer | No buffer; action line is the point of last resort |
Fetal & Maternal Danger Signs — Recognition & Response
| Danger Sign | What It Means | Partograph Code/Finding | Immediate Action | Referral Urgency |
|---|---|---|---|---|
| Abnormal FHR (<110 or >160 bpm) | Fetal hypoxia, distress, or arrhythmia | FHR plotted <110 or >160; may show dips/variable decelerations | Maternal left lateral position, IV fluids, oxygen; confirm lie, rule out cord prolapse/abruption | HIGH (refer to CEmONC with neonatal resuscitation) |
| Meconium (green liquor, code M) | Possible fetal distress or intrauterine passage of meconium | 'M' recorded in amniotic fluid column; if thick meconium, labor is prolonged | Close FHR monitoring every 15 min; if abnormal FHR also present, refer | MODERATE-HIGH (refer to CEmONC with delivery capability if slow labor or FHR abnormal) |
| Blood-stained liquor (code B) | Possible placental abruption, infection, or maternal genital trauma | 'B' recorded in amniotic fluid column; may be accompanied by vaginal bleeding | Assess for abruption signs (pain, bleeding, maternal shock); IV access, referral | EMERGENT (CEmONC with transfusion capability) |
| Maternal tachycardia (>100 bpm) | Dehydration, infection, hemorrhage, or maternal stress/pain | Pulse plotted >100; rising trend over time is more concerning | IV fluids, assess for fever/bleeding/contraction quality; repeat BP | MODERATE (refer if persists or accompanied by fever, bleeding, or slow labor) |
| Hypertension ≥140/90 + proteinuria | Pre-eclampsia; risk of eclamptic seizure, stroke, placental abruption | BP ≥140/90 recorded; urine protein ≥+1; may have headache, epigastric pain, visual changes | Treat as pre-eclampsia; IV access, prepare for magnesium sulfate at facility | EMERGENT (CEmONC with ICU/magnesium sulfate capability) |
| Maternal fever >38°C | Chorioamnionitis or maternal infection; risk to mother and fetus | Temperature >38°C recorded; may have foul-smelling liquor, prolonged rupture of membranes | Assess for rupture of membranes, foul liquor; prepare for IV antibiotics | HIGH (refer to CEmONC for IV antibiotics and delivery assessment) |
| Protracted labor (X right of alert line) | Slow cervical dilatation (<1 cm/hour); labor progress abnormally slow | Multiple 'X' marks plotted to the right of the alert line slope | Reassess contractions, bladder, maternal position, hydration; arrange referral | MODERATE (early referral to CEmONC while mother still stable; not emergent) |
| Arrest of dilatation (≥2 hrs no change) | Cephalopelvic disproportion or exhaustion; labor has stalled completely | 'X' marks remain at same level for 2+ hours despite adequate contractions | Confirm contractions adequate; assess for obstruction signs; refer immediately | HIGH-EMERGENT (CEmONC for evaluation; may need cesarean) |
| Excessive moulding (grade +++) | Fetal skull bones severely overlapped due to prolonged pressure; cephalopelvic disproportion | Moulding recorded as +++ in the partograph; non-reducible overlap | Assess dilatation rate, descent; if slow/arrested, immediate referral | EMERGENT (sign of obstructed labor; CEmONC for cesarean likely needed) |

| Prolonged Latent Phase | Latent-phase labor >8 hours without progression to active phase (≥4 cm) | No plotting on alert/action grid; contractions weak and irregular; cervix <4 cm | Weak contractions, false labor, emotional stress, cephalopelvic disproportion | Reassure, hydrate, rest; assess contractions; if still weak after 8 hrs, consider augmentation or refer | LOW (unless accompanied by other problems; many resolve spontaneously) |
| Protraction (Slow Active Phase) | Cervical dilatation <1 cm/hour during active phase; X drifts RIGHT of alert line | Multiple 'X' marks progressing upward but to the RIGHT of the alert line slope | Weak contractions, inadequate pelvis, maternal exhaustion, malposition | Reassess contractions (frequency/strength/duration); reposition mother; hydrate; consider augmentation if contractions weak; refer while stable | MODERATE (early referral to CEmONC; NOT emergent if mother stable) |
| Arrest of Dilatation | No cervical change for ≥2 hours during active labor despite adequate contractions | 'X' marks plateau at same level for 2+ hours; contractions adequate on chart (solid stippling) | Cephalopelvic disproportion, true obstruction, maternal exhaustion | Confirm contractions truly adequate; assess descent/moulding; if no progress, refer IMMEDIATELY | EMERGENT (CEmONC for full assessment; may need cesarean if true CPD) |
| Arrest of Descent (Second Stage) | Head fails to descend despite full dilation and adequate pushing contractions | 'O' marks on descent line plateau at same fifths level for 30 min (primigravida) or 15 min (multigravida); full dilatation reached | Cephalopelvic disproportion, asynclitism, maternal exhaustion, weak pushing | Assess head position; encourage upright posture, change position; if no descent after conservative measures, refer for assisted delivery or cesarean | EMERGENT (CEmONC with operative delivery capability) |
| Obstructed Labor | Labor where fetus cannot progress through pelvis despite adequate contractions; serious obstetric emergency | X at or past action line; 'O' arrested or very slow descent; moulding +++ or higher; maternal tachycardia, fever, exhaustion; fetal bradycardia | Severe cephalopelvic disproportion, malpresentation (brow/face), contracted pelvis, macrosomia | Treat as EMERGENCY; stabilize (IV access, fluids, antibiotics if fever); REFER IMMEDIATELY to CEmONC for cesarean | EMERGENT (risk of uterine rupture, fistula, fetal death, maternal death) |
| Tonic Contractions (Tetany) | Uterus remains semi-contracted or in constant tone with little relaxation between contractions; abnormal, dangerous pattern | Shading on contraction line shows continuous/nearly continuous filling; little white space between contractions | Overstimulation (oxytocin overdose), obstructed labor, uterine infection | STOP oxytocin immediately if being used; assess for obstruction; reposition mother; REFER immediately | EMERGENT (risk of uterine rupture) |

Partograph Interpretation & Referral Decision Tree
This flowchart shows the step-by-step decision logic for interpreting the partograph and determining when and how urgently to refer. It emphasizes that alert-line crossing triggers EARLY referral (organized, calm), while action-line reaching or obstruction signs trigger EMERGENT referral.
Partograph Recording: Three Families of Information
This mind map organizes all three sections of the partograph (fetal condition, progress of labor, maternal condition) and shows what to record, how often, and what values are normal vs abnormal. Students can use this to quickly recall what each section includes and the key parameters.
Alert Line vs Action Line: The Transfer Zone Safety Buffer
This diagram illustrates the relationship between the alert and action lines, showing the 4-hour transfer zone as the safety buffer. The visual demonstrates that crossing the alert line is the time to REFER (with warning), not a crisis—the action line is a late indicator that referral should have already happened.
Labor Progression States: Normal vs Abnormal Partograph Patterns
This state diagram shows the progression of labor from latent phase through normal delivery, and the alternative pathways when abnormalities appear (prolonged latent, protraction, arrest, obstruction). It illustrates how early recognition at the alert line allows safe transfer, while delayed recognition leads to emergency scenarios.
