Answer to Question 1

ANS: A
Pendelluft is defined as the movement of gases from one area of the lungs to another as a result of differences in the compliance and resistance of various lung regions; this is also called out-of-phase ventilation.

Answer to Question 2

ANS: B
Neurally adjusted ventilatory assist is a mode of ventilation based on neural respiratory input. It relies on detection of the electrical activity of the diaphragm to control ventilator function through a special nasogastric tube that is fitted with an electrode array.
