Which parameter is most useful for assessing adequacy of ventilation during general anaesthesia?
Correct answer: C. End tidal carbon dioxide
- A. Packed cell volume
- B. Peripheral body temperature
- C. End tidal carbon dioxide
- D. Capillary refill time
Explanation
End tidal carbon dioxide provides an estimate of alveolar carbon dioxide and is therefore a useful indicator of ventilation. Temperature and perfusion variables are clinically important but do not directly measure alveolar ventilation.
