Question

Why is it important to ensure that all trapped air is removed from an autoclave for effective sterilization?
Options
A Trapped air can react with steam, forming harmful byproducts.
B Hot air is an inefficient medium for heat transfer, significantly prolonging sterilization time.
Correct Answer
C Air pockets can cause mechanical damage to the autoclave vessel.
D Trapped air prevents the autoclave from reaching the required pressure.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 19, under 'WHY STEAM? (PRINCIPLE)', explains: 'It is very important to ensure that all of the trapped air is removed, as hot air is very poor at achieving sterility. Steam at 134° C can achieve in 3 minutes the same sterility that hot air at 160° C takes two hours to achieve.'

Hint

Consider the comparison between steam and hot air regarding heat transfer efficiency.
