Question

When capnography is in use, an ETCO2 below

A) 20 mmHg
B) 30 mmHg
C) 40 mmHg
D) 50 mmHg

Answer 1

The ETCO2 level during exhalation is around 30 to 40 mmHg.

Step-by-step explanation:

Capnography is a method used to measure the level of carbon dioxide (CO2) in a person's breath. When capnography is in use, the end-tidal carbon dioxide (ETCO2) level is monitored. ETCO2 refers to the partial pressure of carbon dioxide at the end of a breath. In normal healthy individuals, the ETCO2 level during exhalation is around 30 to 40 mmHg.

Therefore, the correct answer to the question is Option C) 40 mmHg.
