Answer to Question 1

ANS: D
Use of HMEs should be avoided in the care of patients with secretion problems and those with low body temperature (<32 C), high spontaneous minute ventilation (>10 L/min), or air leaks in which exhaled tidal volume is less than 70 of delivered tidal volume.

Answer to Question 2

ANS: B
We prefer an optimal humidity approach and use of a heated humidifier to deliver gas in the range of 35 to 37 C at the airway.
