TYK136
Which of the following best describes the correct relationship between fractional end tidal concentratrion [FET] and anticipated anesthetic depth?
a) FET is 65% greater than the partial pressure in the blood
b) FET is 65% less than the partial pressure in the blood
c) FET is unrelated to the partial pressure in the blood
d) FET approximates the partial pressure in the blood

Answer
Answer d.
FET is assumed to be the same as FA (alveolar gas concentration), which approximates the blood partial pressure. Thus, in clinical practice, monitoring end-tidal gas concentration is a useful measure of depth of anesthesia.
