PE24.{2,6-11} | Respiratory Distress Emergency — Summary & Reflection

KEY TAKEAWAYS

Respiratory distress in children progresses from compensated distress (tachypnoea, retractions) to respiratory failure (hypoxaemia, altered consciousness) to arrest along a predictable but rapid trajectory. The triangle of assessment — appearance, work of breathing, circulation to skin — guides severity assessment in 30 seconds. Oxygen delivery devices are selected by severity: nasal cannula (mild, SpO₂ 90–96%), simple mask (moderate), non-rebreather mask (severe, SpO₂ <90%); Venturi mask when precise FiO₂ is required. Infants require neutral/sniffing position (towel under shoulders); children require slight head-tilt. BVM ventilation uses the E-C grip, correct mask size, and chest-rise as the volume endpoint — not full-bag compression. Escalate from oxygen to BVM when SpO₂ fails to respond to maximal non-invasive oxygen, respiratory effort is diminishing, or clinical signs of decompensation appear. The 'quiet child' who stops grunting and fighting is approaching arrest.

REFLECT

Consider an encounter with a sick child you have observed in the paediatric ward or outpatient department. What were the signs of respiratory distress present? Were they assessed systematically using the triangle of assessment framework, or was the assessment focused on a single parameter (e.g., SpO₂ alone)? Reflect on the practical challenges of applying a face mask to a frightened toddler in an emergency — how would you involve the parent, and what communication strategies would reduce the child's distress and improve their oxygen delivery? What aspect of BVM ventilation technique feels most uncertain to you, and what would it take to achieve automaticity in that skill?
