Question

In which of the stage of general anesthesia the movement of the diaphragm is the highest?

(a) Plane 1 of stage III

(b) Plane 2 of stage III

(c) Plane 3 of stage III

(d) Plane 4 of stage III

I had been asked this question in exam.

This key question is from Mechanism of Action of General Anesthetics in chapter Local & General Anesthetics, Opioid Analgesics, Drug Addiction and Drug Abuse of Drug Biotechnology

Answer 1

The correct choice is (a) Plane 1 of stage III

Explanation: The patient’s breath is normal in the 1st stage, then in the 2nd stage patient will have a problem in breathing thus will have scattered breathing, in the plane 1 of stage III The patient will breathe heavily, with slow and normal breathing in plane 2. Increase in the concentration of general anesthesia will cause the death of the patient thus in stage IV the patient breathing stops.
