Sample item

What does a rising end-tidal carbon dioxide trace usually indicate during ventilation?

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

The answer and the reasoning

A. Increased exhaled carbon dioxide or hypoventilation

End-tidal CO2 reflects exhaled gas and rises with hypoventilation, increased production, or rebreathing; it should be interpreted with clinical context.

Option by option

  • A. Increased exhaled carbon dioxide or hypoventilation (correct)

    Correct: CO2 retention commonly raises end-tidal values.

  • B. Guaranteed adequate oxygenation

    Oxygenation requires separate assessment.

  • C. Loss of circuit connection

    Disconnection often lowers or abolishes trace.

  • D. Complete neuromuscular recovery

    Recovery is not determined by CO2 alone.
