A term newborn (38 weeks) delivered vaginally after prolonged labour is noted to be limp, cyanotic, and not breathing at 1 minute of life. Heart rate is 80 bpm. What is the most appropriate immediate next step?

## Clinical Context This newborn has an APGAR score of approximately 3–4 at 1 minute (limp = 0 for muscle tone, cyanotic = 1 for colour, not breathing = 0 for respiratory effort, HR 80 = 1 for heart rate). This is a severely depressed newborn requiring immediate resuscitation. ## Neonatal Resuscitation Algorithm **Key Point:** The Neonatal Resuscitation Program (NRP) algorithm prioritizes the **ABCs of resuscitation**: Airway, Breathing, Circulation. **High-Yield:** At 1 minute with HR > 60 bpm but absent respirations and poor tone, the immediate priority is **positive pressure ventilation (PPV)**, not chest compressions or drugs. ## Why PPV is the Next Step 1. **Heart rate is 80 bpm** — above the threshold of 60 bpm, so chest compressions are NOT yet indicated. 2. **Apnea with poor perfusion** — the primary problem is lack of ventilation; most neonatal bradycardia is due to hypoxia, not primary cardiac disease. 3. **PPV is the most effective intervention** for a hypoxic, apneic newborn with adequate heart rate. ```mermaid flowchart TD A["Newborn at 1 min: HR 80, apneic, cyanotic"]:::outcome --> B{"HR > 60 bpm?"}:::decision B -->|Yes| C{"Breathing adequately?"}:::decision C -->|No| D["Initiate PPV 40–60 breaths/min"]:::action D --> E{"HR increasing & colour improving?"}:::decision E -->|Yes| F["Continue PPV, reassess at 15 sec"]:::action E -->|No| G{"HR < 60 after 15 sec PPV?"}:::decision G -->|Yes| H["Add chest compressions"]:::action B -->|No| H ``` **Clinical Pearl:** PPV should be initiated with room air in term infants; supplemental oxygen is added only if cyanosis persists after 15 seconds of adequate PPV. ## Why Other Options Are Incorrect - **100% oxygen without PPV:** Oxygen alone does not deliver air to the lungs; ventilation is the priority. - **Chest compressions:** Indicated only if HR < 60 bpm after 15 seconds of adequate PPV. Current HR is 80. - **Epinephrine:** Reserved for HR < 60 bpm despite 10 minutes of adequate CPR; far too early here.
