NREMT Paramedic Cognitive ExamAirway, Respiration & VentilationMedium

A 1-year-old infant presents with severe respiratory distress, nasal flaring, grunting, and intercostal retractions. Her respiratory rate is 60 breaths per minute. Her SpO2 is 90% on room air. The most appropriate initial oxygen delivery device for this infant is:

  1. ABlow-by oxygen at 10-15 L/min via a non-rebreather mask held near the face.
  2. BNasal cannula at 2 L/min
  3. CSimple face mask at 6 L/min
  4. DNon-rebreather mask at 10 L/min
Show answer & explanation

Correct answer: A. Blow-by oxygen at 10-15 L/min via a non-rebreather mask held near the face.

For an infant in severe respiratory distress, maximizing oxygen delivery is crucial. While a non-rebreather mask is ideal for high FiO2, it can be poorly tolerated by an anxious or struggling infant. Blow-by oxygen, delivered with a non-rebreather mask held near the face, provides high-concentration oxygen without the emotional distress of a tight-fitting mask, making it the most appropriate initial method.

Why the other options are wrong

  • B. Nasal cannula at 2 L/min provides low FiO2 and is likely insufficient for severe respiratory distress.
  • C. A simple face mask may not deliver sufficient FiO2 and might be poorly tolerated by an infant.
  • D. A non-rebreather mask provides high FiO2 but may increase anxiety and distress in an infant, potentially worsening respiratory effort if not tolerated.

Pediatric Oxygen Delivery

Oxygen delivery in pediatric patients requires consideration of age, tolerance, and the need for high FiO2. Blow-by oxygen is often preferred for infants and young children in respiratory distress who may not tolerate a tight-fitting mask, providing high-concentration oxygen without increasing anxiety.

  • Infants/children may become agitated by tight masks.
  • Blow-by oxygen delivers high FiO2 if flow is high and mask is close.
  • Goal is to improve oxygenation while minimizing distress.
