Midwife Licensure Exam Independent Delivery & Emergency Obstetric Care — Partograph Use & Referral Decision-MakingSummary

The partograph is divided into three functional sections: (1) **Fetal condition** (top)—plots fetal heart rate (FHR), amniotic fluid status with coded letters [I=intact, C=clear, M=meconium, B=blood-stained, A=absent], and fetal skull moulding [0=separated, +=touching, ++=overlapping reducible, +++=overlapping non-reducible]; (2) **Labor progress** (center)—the most critical section, plots cervical dilatation in centimeters (using X), descent of the fetal head in fifths palpable above the pelvic brim (using O), and uterine contractions per 10 minutes with shading to show strength (light=<20 sec, diagonal=20–40 sec, solid=>40 sec); (3) **Maternal condition** (bottom)—records pulse, blood pressure, temperature, urine findings, and medications administered. All three sections are plotted against **time in hours** on one page, allowing quick visual assessment of the whole labor picture.

Consistent, timely recording is what keeps the partograph accurate and trustworthy. In the **active first stage**, standard frequencies are: **FHR every 30 minutes** (immediately after a contraction; every 5–15 minutes in second stage if abnormal); **contractions every 30 minutes**, counting number per 10 minutes and duration; **cervical dilatation by vaginal examination every 4 hours** (sooner if labor accelerates or problems suspected—avoid over-examining to reduce infection risk); **descent at each vaginal examination**; **maternal pulse every 30 minutes**; **blood pressure every 4 hours**; **temperature every 2–4 hours**; **urine each time she voids**. In the second stage, frequency increases to monitor fetal well-being and descent more closely.

The **active phase** of the first stage traditionally begins at **4 cm dilatation** with regular, strong contractions, and the cervix is expected to dilate at a rate of **at least 1 cm per hour**. On the partograph, plotting begins at this point, and the **alert line** is drawn from the 4-cm mark upward at a slope of exactly **1 cm per hour**, reaching 10 cm (full dilatation) at the expected time. The alert line represents the **slowest normal progress**—a line that separates normal from abnormally slow labor. If the mother's cervical dilatation (marked with an X) stays **to the left of or on the alert line**, her labor is progressing normally, and supportive care continues. If the X **crosses to the right of the alert line**, labor is slower than expected—this is a **warning signal** that prompts action: reassess contractions, bladder, position, hydration; and begin **arranging referral** to a facility capable of performing a cesarean section.

The **action line** is drawn **4 hours to the right of, and parallel to, the alert line**. If cervical dilatation reaches the action line, labor is significantly obstructed or prolonged, and **immediate decisive action is mandatory**—the mother **must already be in a CEmONC facility** for full assessment and definitive management (augmentation with IV oxytocin if appropriate for the clinical picture, or emergency cesarean). The **space between the alert and action lines** is the **transfer zone** or **decision zone**—a 4-hour safety buffer built into the partograph. This gap gives the midwife time to recognize slow progress (crossing the alert line), arrange transport, stabilize the mother (IV line, fluids, bladder emptying), and move her to a comprehensive facility **before** labor becomes a full obstetric emergency. The transfer zone acknowledges the reality of rural practice: a mother cannot teleport to a hospital; she needs time to be moved safely.

The progress of labor is tracked by two key measurements plotted on the central grid: **Cervical dilatation (X)** is measured in centimeters (0–10 cm) during vaginal examination and marked with an X on the vertical scale corresponding to the time of examination. The cervix is expected to dilate at ≥1 cm per hour in the active phase; if progress is slower, the X plots to the right of the alert line. **Descent of the fetal head (O)** is measured by abdominal palpation and recorded as **fifths of the head palpable above the pelvic brim** (5/5 = entire head mobile above brim; 0/5 = head fully engaged). Descent is expected to proceed as dilation progresses; the O is plotted on the same time axis as the X. **Stalled descent** (the O not moving downward despite good contractions) or **arrest of descent** (no change for ≥2 hours) signals cephalopelvic disproportion or malposition and requires referral for assessment. The two symbols together paint a picture of whether the baby is moving down with the opening cervix—normal—or whether the head is stuck while the cervix dilates (obstructed labor).

The partograph records contractions by shading a box for each contraction occurring during a 10-minute observation period. The shading pattern indicates strength and duration: **light stippling** = contractions lasting <20 seconds (weak/ineffective); **diagonal lines** = contractions lasting 20–40 seconds (moderate); **solid/dark filling** = contractions lasting >40 seconds (strong). **Good labor** is defined as **3–5 contractions in 10 minutes, each lasting ≥40 seconds**. Weak, short, or infrequent contractions (e.g., 1–2 per 10 minutes lasting <30 seconds) result in **poor progress** and are plotted to the right of the alert line. **Tachysystole** (>5 contractions per 10 minutes or contractions lasting >90 seconds) can be harmful if accompanied by fetal distress or exhaustion. The pattern of contractions is often the first clue to the cause of slow progress: strong, frequent contractions with no cervical change = obstruction; weak or infrequent contractions with no change = poor labor / inadequate uterine activity.

**Fetal heart rate (FHR)** is recorded at each observation (usually every 30 minutes during the first stage). **Normal FHR ranges from 110 to 160 beats per minute.** FHR below 110 or above 160, or FHR that falls *after* contractions (suggesting poor placental perfusion during uterine tightening), indicates **fetal distress** and requires immediate action: reposition mother to left lateral, give fluids, increase oxygen, and arrange urgent referral. **Amniotic fluid** status is noted with a letter code: **I** = intact membranes; **C** = ruptured membranes, clear fluid (normal); **M** = meconium-stained fluid (sign of possible fetal distress or post-maturity); **B** = blood-stained fluid (concerning for placental abruption or other bleeding); **A** = absent (dry, suggesting prolonged rupture or oligohydramnios). **Fetal skull moulding** reflects the degree to which the skull bones overlap due to compression against the pelvis: **0** = bones separated or just touching (normal in early active phase); **+** = bones touching; **++** = bones overlapping but reducible (moderate molding, concerning if progressive); **+++** = bones overlapping and not reducible (severe, non-reducible molding—sign of significant compression/obstruction). **Increasing moulding (++ or +++) with slow cervical progress and high head position signals cephalopelvic disproportion and is an urgent indication for referral.**

The lower section of the partograph records **maternal pulse** (every 30 minutes), **blood pressure** (every 4 hours or more frequently if raised), **temperature** (every 2–4 hours), and **urine output and findings** (protein, acetone/ketones, with each void). These observations detect maternal complications that demand referral: **Rising pulse and temperature** suggest dehydration, exhaustion, or infection—common in prolonged labor or prolonged rupture of membranes. Fever (≥38.5°C) with or without leaking fluid is a sign of **chorioamnionitis or intra-amniotic infection**; refer urgently. **Blood pressure ≥140/90 mmHg** is abnormal in labor and demands investigation for pre-eclampsia, especially if accompanied by **proteinuria (++), headache, visual disturbance, or epigastric pain**—these are danger signs of **hypertensive emergency** and require urgent referral to a facility for antihypertensive drugs, seizure prophylaxis (MgSO₄), and possible delivery. **Acetone in urine** (dark-staining, fruity smell) indicates **ketonuria** from severe dehydration and starvation during prolonged labor; fluid and caloric support are needed. **Oliguria** (scant or absent urine) can signal dehydration, exhaustion, or the early stage of preeclampsia-related renal involvement.

The partograph makes pathological labor patterns visible: **Prolonged latent phase** = latent phase exceeding 8 hours with no progression to the active phase; reassess and prepare for referral if it persists. **Prolonged active phase / protraction** = cervical dilatation crossing to the right of the alert line, progressing slower than 1 cm/hour; arrange referral, assess for adequate contractions, bladder distension, maternal position, and dehydration. **Arrest of dilatation** = no cervical change for ≥2 hours in the active phase; indicates obstruction or inadequate contractions; refer. **Arrest of descent** = the fetal head (O) not descending despite good contractions for ≥2 hours; indicates cephalopelvic disproportion; refer. **Excessive moulding (++)** or **(+++)** with slow progress and high head = mechanical obstruction; urgent referral. Additional danger signs: **Bandl's ring** (a visible ridge on the maternal abdomen between upper and lower uterine segments, palpable as a ridge from below the umbilicus upward), **a retracted, tonic (constantly contracted) uterus**, **maternal exhaustion and delirium**, **rapid maternal pulse (>120 bpm)**, **rising temperature**, and **bloody or foul-smelling vaginal discharge** all indicate **obstructed labor**, a true obstetric emergency with risk of **uterine rupture, fetal death, and maternal death**. Immediate referral to a surgical facility is life-saving.

The midwife refers when the partograph or clinical examination reveals findings indicating the birth cannot be safely managed in the current setting. **Referral triggers include:** (1) **Cervical dilatation crossing the alert line** = slow progress, arrange referral (not necessarily emergency, but plan transfer); (2) **Reaching the action line** = obstructed/prolonged labor, must already be in CEmONC facility or transfer immediately; (3) **Abnormal FHR** (<110 or >160 bpm, or falling after contractions) = fetal distress; (4) **Meconium-stained or blood-stained amniotic fluid** = possible fetal compromise; (5) **Excessive moulding (++) or (+++)** with slow progress = cephalopelvic disproportion; (6) **Arrest of dilatation or descent** (≥2 hours with no change) = obstruction; (7) **Antepartum or intrapartum hemorrhage** (any significant bleeding) = risk of placental abruption, accreta, or other surgical emergency; (8) **Blood pressure ≥140/90 with proteinuria, headache, visual changes, or epigastric pain** = pre-eclampsia/eclampsia; (9) **Fever ≥38.5°C** = chorioamnionitis or infection; (10) **Malpresentation or malposition** (breech, transverse lie, brow, face, posterior occiput in prolonged labor) = risk of obstructed labor or cord prolapse; (11) **Multiple pregnancy, prematurity, or previous cesarean** = higher risk; (12) **Prolonged rupture of membranes (≥18 hours) with no progress** = infection risk. In the Philippine context, any of these findings at a RHU, health center, or lying-in clinic should trigger activation of the **referral system**—transport, communication with the receiving CEmONC facility, and safe escort.

Once referral is decided, the midwife executes it safely using the **R checklist**: (1) **Recognize** the problem early (using the partograph and clinical judgment); (2) **Refer promptly**—act on the alert line, not the action line; do not delay; (3) **Resuscitate/stabilize first** where needed: establish an **IV line** with normal saline, give first-aid drugs (e.g., activated charcoal if poisoning, magnesium sulfate or nifedipine if preeclamptic, antibiotics if infection suspected), reposition mother to left lateral, give oxygen if fetal distress, empty bladder if full, comfort and reassure; (4) **Records**: complete the **referral form** with clinical summary, partograph findings, and interventions given; send it with the mother; (5) **Ride/escort**: arrange **safe transport** (preferably motorized if available) and ensure a **skilled companion** (a health worker, the midwife herself if possible, or a trained family member) travels with the mother to provide basic support and communicate findings to the receiving facility; (6) **Ring ahead**: **communicate with the receiving CEmONC facility**—phone call or text if possible—to alert them of the mother's arrival, vital findings (e.g., "G2P1 with arrest of dilation at 6 cm, excessive molding, tachycardia, on IV fluids"), and estimated time of arrival so they can prepare. **STABLE transfer** principles ensure that the mother arrives at the hospital in the best possible condition: **S** = signs checked and recorded; **T** = temperature managed; **A** = airway kept patent; **B** = breathing monitored; **L** = level of consciousness noted; **E** = exposure (keep warm, privacy). In a PHP/BHW context, this means checking blood pressure, pulse, FHR and fetal movement, temperature; ensuring the mother can breathe (left lateral position if possible, oxygen if available); and keeping her warm and informed.

The **alert line** is the visual and conceptual heart of the partograph as a referral tool. A mother admitted at 4 cm in active labor has her first X plotted on the alert line. As labor progresses, her cervix should dilate at ≥1 cm per hour; if so, subsequent X's plot to the **left of or on the alert line**, indicating **normal progress**. As long as the X stays left of the line, the midwife continues normal supportive care: encouragement, position changes (upright, squatting, lateral, all-fours), hydration, nutrition (light foods or broth), ambulation if comfortable, companionship, and pain relief (no pharmacological restriction in normal labor in most Philippine settings; massage, counterpressure, breathing techniques, intermittent fetal auscultation, and emotional support are foundational). **If the X crosses to the right of the alert line**, labor is progressing slower than the minimum expected rate. This is the **warning zone**. The midwife now: reassesses whether contractions are adequate and well-spaced, checks for a full bladder or bowel, ensures the mother is hydrated and not exhausted, evaluates position (upright, forward-leaning positions often help), and **begins planning referral**. She does not panic or declare the labor 'failed,' but she acknowledges the slow progress and activates the referral system to move the mother to a place where labor can be augmented (with oxytocin) or managed operatively if needed. This is the moment when the midwife shifts from the mindset of independent attendant to coordinator of care—she remains the mother's advocate but now coordinates with the referral facility.

The partograph **alert and action lines only apply to the active phase of labor**. The **latent phase** (cervix from 0 to 4 cm) is highly variable in duration; a mother may labor for hours with slow, irregular contractions and minimal dilatation before entering the active phase. Plotting the latent phase on the alert/action grid would pathologize normal variation and lead to unnecessary intervention. Instead, the **latent phase is assessed separately**: it is considered **prolonged** if it exceeds **8 hours** (or if progress seems arrested). A prolonged latent phase may warrant reassurance and rest (e.g., rest with sedation if the mother is exhausted), or referral if the history or clinical picture suggests cephalopelvic disproportion or other complications. **Once the cervix reaches 4 cm with strong, regular contractions**, labor enters the **active phase**, and plotting on the alert/action grid begins. The first X is plotted on the alert line at the time of admission, and subsequent measurements are tracked. The distinction is vital for exam: a mother in the latent phase with a cervix at 2 cm and weak contractions is not yet in obstructed labor; she may need rest, support, and reassurance, not referral. But if she remains at 2 cm with no progress after 8 hours, latent-phase dysfunction is diagnosed, and she should be transferred for evaluation.

The fetal heart rate and amniotic fluid status recorded at the top of the partograph reflect fetal well-being, while the maternal pulse, temperature, and urine findings at the bottom reflect maternal stress. In normal labor, both remain stable. In prolonged or obstructed labor, both deteriorate together: FHR may fall or become reactive, meconium may appear, maternal pulse rises, temperature climbs, urine shows acetone. Watching these two 'sides' of the partograph together reveals whether the labor is safe or becoming dangerous.

The cervical dilatation (X) and fetal descent (O) are expected to progress *as a result of* adequate contractions. The partograph plots all three on the same time axis. If contractions are strong and frequent but dilatation/descent stall, obstruction is likely. If contractions are weak but dilatation/descent progress normally, labor is inefficient but may proceed with support or augmentation. The interplay reveals the mechanism: are the contractions driving progress, or is something blocking the way?

Crossing the alert line (slow dilatation) is often accompanied by rising maternal pulse, temperature, and ketonuria—signs of maternal exhaustion and stress. The two together tell a story: the labor is stalled mechanically (slow dilatation), and the mother is paying an energetic cost (rising pulse, fever, ketones). This combination justifies early referral; prolonging such labor exhausts the mother and increases infection and complication risks. The partograph makes this story visible.

In normal labor, the fetal head gradually flexes and moulds as it descends through the pelvis; mild moulding is expected. But in obstructed labor, the head is trapped—it cannot descend because the pelvis is too small. The uterus keeps contracting against the immobile head, and the skull bones are forced to overlap more and more. On the partograph, increasing moulding (+ → ++ → +++) combined with slow dilatation and high head position is the classic signature of cephalopelvic disproportion and impending obstructed labor. Recognizing this pattern is the key to preventing uterine rupture.

The entry into the active phase (4 cm with strong contractions) is the moment when the partograph enters 'mode': plotting begins, referral thresholds activate, and the team shifts from waiting-and-seeing to active monitoring. At the same moment, the referral system should be 'on standby'—the midwife should have already identified where and how the mother would be transferred if needed, established communication with the referral facility, and ensured transport is available. The partograph's start is not just a charting event; it is a system activation.

The 4-hour gap between the alert and action lines represents the time available for safe referral. If a mother crosses the alert line at hour 6 of labor and transfer arrangements take 1–2 hours, she will arrive at the hospital still in the transfer zone, where labor can still be managed (augmented or delivered operatively under planned, controlled conditions). But if recognition is delayed and she reaches the action line without being in a facility, she is now in obstructed labor in an unsuitable place—a crisis. The transfer zone is the 'golden hours' for safe action; the midwife's job is to use them wisely.
