Anaesthesia · Neonatal resuscitation: initial oxygen

Sample item

A term baby requires positive pressure ventilation at birth. Which initial inspired oxygen concentration is recommended?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. 21 percent (room air)

In term and late preterm newborns, resuscitation starts with room air and oxygen is titrated using pulse oximetry targets. Routine 100 percent oxygen causes oxidative injury. Ventilation of the lungs is the most important step.

Option by option

  • A. 21 percent (room air) (correct)

    Correct. Room air is the starting concentration for term infants.

  • B. No oxygen under any circumstances

    Oxygen is added if targets are not reached.

  • C. 100 percent

    100 percent oxygen is not recommended initially.

  • D. 50 percent

    50 percent is not the standard start for term infants.
