12.1 Neonatal Resuscitation Program (NRP 8th Edition) & Delivery Room Resuscitation
Key Takeaways
- The Golden Minute & Initial Assessment: Initial evaluation within 60 seconds (gestational age, muscle tone, breathing/crying) determines whether the newborn remains skin-to-skin with the mother or is transferred to the radiant warmer; Positive Pressure Ventilation (PPV) is indicated for apnea, gasping, or heart rate <100 bpm, initiated in room air (21% FiO2) for infants ≥35 weeks and 21%–30% FiO2 for preterm infants <35 weeks.
- Ventilation Corrective Steps (MR. SOPA): If PPV fails to achieve chest rise or heart rate improvement, immediately execute MR. SOPA: Mask adjustment, Reposition airway, Suction mouth/nose, Open mouth, Pressure increase (up to 30–40 cmH2O in term infants), and Alternative airway (endotracheal tube or laryngeal mask).
- Coordinated Cardiopulmonary Resuscitation: Chest compressions are indicated only after at least 30 seconds of effective PPV moving the chest if heart rate remains <60 bpm, utilizing the two-thumb encircling-hands technique at a 3:1 ratio (90 compressions : 30 breaths/min, 120 events/min) with FiO2 increased immediately to 100%.
- Emergency Medications & Volume Expansion: Epinephrine (0.1 mg/mL / 1:10,000) at 0.02 mg/kg (0.2 mL/kg) IV/IO followed by a 3 mL normal saline flush is indicated for persistent heart rate <60 bpm despite 60 seconds of coordinated CPR; isotonic crystalloid (normal saline) or uncrossed O-negative PRBCs at 10 mL/kg over 5–10 minutes is reserved for acute hypovolemic shock.
- Special Clinical Pathways: Non-vigorous infants born through meconium-stained amniotic fluid receive standard resuscitation under the radiant warmer without routine endotracheal suctioning; congenital diaphragmatic hernia strictly contraindicates face-mask PPV, demanding immediate endotracheal intubation and Replogle tube gastric decompression.
NRP 8th Edition Fundamentals & The Golden Minute
Approximately 10% of all neonates require some degree of active assistance to initiate breathing at birth, while fewer than 1% require intensive resuscitative interventions such as chest compressions, endotracheal intubation, or emergency pharmacotherapy. The Neonatal Resuscitation Program (NRP 8th Edition), published by the American Academy of Pediatrics (AAP) and the American Heart Association (AHA), provides a standardized, evidence-based algorithm designed to prevent neonatal hypoxic-ischemic organ damage and establish functional pulmonary gas exchange.
Resuscitation begins prior to delivery with the 4 Pre-Birth Questions:
- What is the expected gestational age?
- Is the amniotic fluid clear?
- How many babies are expected?
- Are there any additional risk factors?
These questions allow the multidisciplinary team to assemble required personnel, assign structured clinical roles (team leader, airway provider, circulation/compressions provider, medication/recorder nurse), and verify emergency equipment readiness utilizing a standardized checklist.

• Start PPV within 60 seconds of birth • Continuous Pulse Oximetry (Right Wrist)

• Rate: 40-60 breaths/min • Titrate supplemental oxygen to target SpO2
• Attach pre-ductal pulse oximeter & ECG
The Golden Minute Concept
The Golden Minute represents the initial 60 seconds of life during which the neonatal transition team must complete the initial evaluation, execute initial stabilization steps on the radiant warmer (warm, position, clear airway if indicated, dry, stimulate), re-evaluate heart rate and respiratory effort, and initiate Positive Pressure Ventilation (PPV) if the infant is apneic, gasping, or has a heart rate $<100\text{ bpm}$. Delaying PPV beyond the first minute increases the risk of severe hypoxic encephalopathy and cardiovascular collapse.
Positive Pressure Ventilation (PPV) Mechanics & FiO2 Titration
Ventilation of the lungs is the single most important and effective step in cardiopulmonary resuscitation of the compromised newborn. Fluid-filled alveoli must be inflated with gas to establish Functional Residual Capacity (FRC), lower pulmonary vascular resistance (PVR), and allow oxygen to diffuse into pulmonary capillary blood.
+---------------------------------------------------------------------------------------------------+
| PPV TECHNICAL PARAMETERS & INITIAL SETTINGS |
+---------------------------------------------------------------------------------------------------+
Parameter Clinical Specification & Practice Standard
---------------------- ---------------------------------------------------------------------------
Initial FiO2 (≥35 wk) 21% Oxygen (Room Air). Clinical trials demonstrate 100% O2 increases
mortality and causes toxic oxygen free radical myocardial/cerebral injury.
---------------------------------------------------------------------------------------------------
Initial FiO2 (<35 wk) 21% to 30% Oxygen. Titrate upward using an air-oxygen blender based on
minute-by-minute pre-ductal SpO2 target nomograms.
---------------------------------------------------------------------------------------------------
Ventilation Rate 40 to 60 breaths per minute. Cadence mnemonic:
"Breathe (squeeze mask), Two (release), Three (release), Breathe..."
---------------------------------------------------------------------------------------------------
Initial PIP & PEEP • Peak Inspiratory Pressure (PIP): 20 to 25 cmH2O (sufficient to move chest).
• Positive End-Expiratory Pressure (PEEP): 5 cmH2O (via T-piece resuscitator).
---------------------------------------------------------------------------------------------------
Device Hierarchy 1. T-piece Resuscitator (NeoPuff): Delivers consistent PIP and PEEP.
2. Flow-inflating Bag (Anesthesia bag): Requires gas source, delivers CPAP.
3. Self-inflating Bag: Portable, does not require gas, cannot deliver CPAP.
+---------------------------------------------------------------------------------------------------+
Pre-Ductal Pulse Oximetry and Target SpO2 Progression
Pulse oximetry must always be placed on the right hand or wrist (pre-ductal) because blood perfusing the right arm branches from the innominate (brachiocephalic) artery before the ductus arteriosus enters the aorta. This accurately reflects cerebral and myocardial arterial oxygen saturation.
| Elapsed Time from Birth | NRP Target Pre-Ductal $SpO_2$ Range |
|---|---|
| 1 Minute | 60% – 65% |
| 2 Minutes | 65% – 70% |
| 3 Minutes | 70% – 75% |
| 4 Minutes | 75% – 80% |
| 5 Minutes | 80% – 85% |
| 10 Minutes | 85% – 95% |
The MR. SOPA Corrective Ventilation Algorithm
When PPV is initiated, the team assesses for heart rate increase (the primary indicator of successful ventilation) and chest movement. If the heart rate does not increase and the chest is not moving after the initial 15 seconds of PPV, ventilation is ineffective. The team must immediately announce and execute the MR. SOPA ventilation corrective steps:
+---------------------------------------------------------------------------------------------------+
| MR. SOPA VENTILATION CORRECTIVE SEQUENCE |
+---------------------------------------------------------------------------------------------------+
[ STEP 1: M & R ]
• M - MASK ADJUSTMENT: Reapply mask with two-point top-to-bottom seal; use C-grip.
• R - REPOSITION AIRWAY: Adjust head to neutral "sniffing" position; avoid hyperextension.
• ACTION: Provide 5 PPV breaths and assess chest movement.
│
▼ (If No Chest Movement)
[ STEP 2: S & O ]
• S - SUCTION MOUTH & NOSE: Clear secretions with bulb syringe or 8F/10F catheter (80-100 mmHg).
• O - OPEN MOUTH: Lift mandible forward; insert small oral airway if necessary.
• ACTION: Provide 5 PPV breaths and assess chest movement.
│
▼ (If No Chest Movement)
[ STEP 3: P ]
• P - PRESSURE INCREASE: Increase Peak Inspiratory Pressure in 5 cmH2O increments.
(Maximum recommended: 30 cmH2O in preterm infants; 40 cmH2O in term infants).
• ACTION: Provide 5 PPV breaths and assess chest movement.
│
▼ (If No Chest Movement)
[ STEP 4: A ]
• A - ALTERNATIVE AIRWAY: Insert Endotracheal Tube (ETT) or Laryngeal Mask Airway (LMA).
• Secure airway, connect CO2 detector (Colorimetric: "Yellow is Mellow" = ET CO2 confirmed),
and deliver 30 seconds of PPV through alternative airway.
Endotracheal Intubation & Laryngeal Mask Airway (LMA) Specifications
| Gestational Age | Estimated Weight | Endotracheal Tube (ETT) Size (ID) | Depth of Insertion (Nasal-Tragus Length + 1 cm or Lip-to-Tip) |
|---|---|---|---|
| <28 weeks | $<1,000\text{ g}$ | 2.5 mm uncuffed | Lip-to-tip: 5.5 – 6.5 cm (or weight in kg + 6 cm) |
| 28 – 34 weeks | $1,000\text{--}2,000\text{ g}$ | 3.0 mm uncuffed | Lip-to-tip: 6.5 – 7.5 cm |
| 34 – 38 weeks | $2,000\text{--}3,000\text{ g}$ | 3.5 mm uncuffed | Lip-to-tip: 7.5 – 8.5 cm |
| >38 weeks | $>3,000\text{ g}$ | 3.5 – 4.0 mm uncuffed | Lip-to-tip: 8.5 – 9.5 cm |
Laryngeal Mask Airway (LMA / Size 1): Indicated as an effective rescue supraglottic airway in infants $\ge 34\text{ weeks}$ or $\ge 1.5\text{ kg}$ when face-mask ventilation is unsuccessful ("cannot ventilate") and endotracheal intubation cannot be achieved ("cannot intubate").
Chest Compressions & Coordinated CPR Protocols
Chest compressions are indicated ONLY when the neonatal heart rate remains below 60 beats per minute despite at least 30 seconds of effective PPV that moves the chest, preferably delivered via a secured endotracheal tube or laryngeal mask.
+---------------------------------------------------------------------------------------------------+
| NEONATAL CHEST COMPRESSIONS: TECHNICAL SPECIFICATIONS |
+---------------------------------------------------------------------------------------------------+
Technique Parameter Standard NRP 8th Edition Practice
---------------------- ---------------------------------------------------------------------------
Technique Method Two-Thumb Encircling-Hands Technique (Preferred over 2-finger technique).
Thumbs placed on lower third of sternum (just below intermammary line);
fingers encircle thorax to support the back.
---------------------------------------------------------------------------------------------------
Compression Depth One-third (1/3) of the anterior-posterior (AP) diameter of the chest.
Allow complete chest recoil between compressions without lifting thumbs.
---------------------------------------------------------------------------------------------------
Ratio & Cadence 3:1 Compression-to-Ventilation Ratio.
• 3 rapid compressions followed by 1 positive-pressure breath.
• Cadence: "One-and-Two-and-Three-and-Breathe-and..."
• Delivers 90 compressions and 30 breaths = 120 total cycles per minute.
---------------------------------------------------------------------------------------------------
Oxygen Concentration Increase FiO2 immediately to 100% upon initiating chest compressions.
---------------------------------------------------------------------------------------------------
Monitoring & Duration Continuous 3-Lead ECG monitoring is the gold standard for rapid, accurate
heart rate assessment. Perform CPR for a full 60 seconds before pausing
briefly to reassess heart rate.
+---------------------------------------------------------------------------------------------------+
Emergency Resuscitation Pharmacotherapy & Vascular Access
When severe bradycardia ($HR < 60\text{ bpm}$) persists despite 60 seconds of coordinated chest compressions and 100% FiO2 PPV via a secure airway, emergency medications are indicated.
+---------------------------------------------------------------------------------------------------+
| NRP EMERGENCY MEDICATIONS & FLUID PROTOCOL |
+---------------------------------------------------------------------------------------------------+
[ 1. EPINEPHRINE (1:10,000 / 0.1 mg/mL) ]
• INDICATIONS: Heart rate <60 bpm after 60 seconds of effective compressions and 100% PPV.
• MECHANISM: Alpha-1 vasoconstriction increases aortic diastolic pressure, driving coronary and
cerebral perfusion; Beta-1 inotropic and chronotropic myocardial stimulation.
• PREFERRED INTRAVENOUS / INTRAOSSEOUS (IV/IO) DOSE:
0.02 mg/kg (0.2 mL/kg of 0.1 mg/mL solution) administered rapid push, followed immediately
by a 3 mL Normal Saline flush to clear catheter dead space.
• ENDOTRACHEAL (ET) DOSE (Temporary bridge while establishing IV/IO access):
0.1 mg/kg (1.0 mL/kg of 0.1 mg/mL solution) instilled directly into ETT, followed by PPV.
• DOSING INTERVAL: Repeat every 3 to 5 minutes if heart rate remains <60 bpm.
│
▼
[ 2. VOLUME EXPANSION (ISOTONIC CRYSTALLOID OR PRBCs) ]
• INDICATIONS: Suspected acute hypovolemia or fetal blood loss (placental abruption, vasa previa,
cord avulsion, severe feto-maternal hemorrhage) with poor response to resuscitation, pallor,
weak/absent pulses, and delayed capillary refill.
• AGENTS: Normal Saline (0.9% NaCl) OR Uncrossed Type O-Negative Packed Red Blood Cells (PRBCs).
• DOSING & ROUTE: 10 mL/kg IV/IO infused steadily over 5 to 10 minutes.
• CAUTION: Avoid rapid high-volume crystalloid pushes in preterm infants due to risk of
Intraventricular Hemorrhage (IVH).
│
▼
[ 3. EMERGENCY VASCULAR ACCESS MODALITIES ]
• UMBILICAL VENOUS CATHETER (UVC): Emergency low-lying placement (3.5F or 5.0F catheter inserted
2 to 4 cm until free blood return is aspirated; below hepatic vein).
• INTRAOSSEOUS (IO) NEEDLE: Inserted into anteromedial aspect of proximal tibia (1-2 cm below
tibial tuberosity) when umbilical access is unavailable.
CONTRAINDICATED DELIVERY ROOM DRUGS:
- Naloxone: Strictly contraindicated in neonatal resuscitation. In opioid-exposed infants, naloxone precipitates acute neuro-withdrawal, intractable seizures, and severe pulmonary edema.
- Sodium Bicarbonate: Contraindicated during acute CPR; generates gaseous $CO_2$ that diffuses into myocardium and brain, causing paradoxical intracellular acidosis and cerebral hemorrhage.
Special Delivery Room Resuscitative Emergencies
1. Meconium-Stained Amniotic Fluid (MSAF)
Historically, non-vigorous infants born through meconium were routinely intubated for direct tracheal suctioning prior to drying or stimulation. Current NRP guidelines strictly advise against routine intubation and tracheal suctioning for non-vigorous infants with meconium.
- If the infant is vigorous: Keep with parent for skin-to-skin care.
- If the infant is non-vigorous (depressed respirations or hypotonia): Move to radiant warmer, perform initial stabilization steps, and initiate PPV within 60 seconds if apneic or bradycardic. Endotracheal intubation is performed only if airway obstruction is suspected or MR. SOPA requires an alternative airway.
2. Congenital Diaphragmatic Hernia (CDH)
- Anatomy: Herniation of abdominal viscera (stomach, intestines, spleen) into the thoracic cavity through a posterolateral defect in the diaphragm (Bochdalek hernia, 85% left-sided), causing severe pulmonary hypoplasia and persistent pulmonary hypertension.
- Clinical Presentation: Scaphoid (sunken) abdomen, barrel-shaped chest, bowel sounds auscultated over the left hemithorax, shifted heart sounds to the right, severe respiratory failure at birth.
- CRITICAL RESUSCITATION MANDATE: STRICTLY CONTRAINDICATE FACE-MASK PPV. Bag-mask ventilation forces air into the intrathoracic stomach and bowel, causing rapid intestinal distention, massive mediastinal compression, contralateral lung collapse, and pneumothorax.
- Priority Action: Immediate endotracheal intubation in the delivery room and placement of a double-lumen Replogle or Oro-gastric (OG) tube (10F) to continuous low suction to decompress the gastrointestinal tract.
3. Pierre Robin Sequence
- Triad: Micrognathia (mandibular hypoplasia), glossoptosis (posterior tongue displacement), and cleft palate.
- Airway Crisis: The recessed tongue occludes the pharyngeal airway, causing severe inspiratory obstruction.
- Interventions: Place infant in the prone position (gravity pulls tongue forward); insert a nasopharyngeal airway (NPA) using a 2.5–3.0 mm ETT inserted through the nares into the posterior pharynx.
A term neonate delivered by emergency cesarean for fetal bradycardia is apneic and limp at birth. The nurse moves the infant to the radiant warmer, dries, stimulates, and positions the airway. At 45 seconds of life, the apical heart rate is 70 bpm and the infant remains apneic. According to NRP 8th Edition guidelines, what is the mandatory immediate nursing action?
A late-preterm neonate (35 weeks) receives PPV via a face mask for apnea and a heart rate of 80 bpm. After 15 seconds of ventilation, the heart rate remains 80 bpm and no chest rise is observed. Which sequence of corrective actions should the resuscitation team perform?
A full-term infant with meconium-stained amniotic fluid is intubated and receiving effective positive pressure ventilation. Despite 30 seconds of confirmed bilateral chest rise via endotracheal tube, the 3-lead ECG demonstrates a persistent heart rate of 48 bpm. What are the nurse's priority simultaneous interventions?
A newborn delivered at 38 weeks presents with severe respiratory distress, a scaphoid abdomen, and bowel sounds auscultated over the left hemithorax. Heart sounds are displaced to the right. Which action is strictly contraindicated during delivery room resuscitation?
