Sample item

What is capnography particularly useful for confirming after intubation?

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

The answer and the reasoning

C. Persistent tracheal carbon dioxide exhalation

A sustained capnography waveform after ventilation confirms exhaled carbon dioxide and is the most reliable immediate indicator of tracheal tube placement.

Option by option

  • A. Full neuromuscular recovery

    Block recovery needs nerve stimulation.

  • B. Adequate haemoglobin concentration

    Haemoglobin is unrelated.

  • C. Persistent tracheal carbon dioxide exhalation (correct)

    Correct: persistent waveform confirms ventilated tracheal placement.

  • D. Correct endotracheal tube depth on X-ray

    X-ray can assess depth later.
