Answer to Question 1

ANS: A
The ideal HME should operate at 70 efficiency or better (providing at least 30 mg/L water va-por); use standard connections; have a low compliance; and add minimal weight, dead space, and flow resistance to a breathing circuit.

Answer to Question 2

ANS: C
There are three basic types of HMEs: (1) simple condenser humidifiers, (2) hygroscopic conden-ser humidifiers, and (3) hydrophobic condenser humidifiers.
