Question

Quizplus · Accepted Answer

The correct value for PaCO2 (partial pressure of carbon dioxide in the blood) in the drowning sequence of a conscious person is actually increasing, not decreasing. Option A (attempted breath holding) and B (violent swallowing efforts) are both part of the drowning sequence. Option D (PaO2 in the blood falling below 50 mmHg) is also part of the drowning sequence, as oxygen levels in the blood decrease due to inability to breathe properly.
