If a patient's minute volume is 8.5 L/min and his respiratory rate is 15 breaths/min, his average ...

(Answer to Q. 1)  ANS: B
Minute volume = tidal volume  respiratory rate.
Tidal volume = minute volume  respiratory rate.
Tidal volume = 8.5 L/min  15 breaths/min.
Tidal volume = 0.570 L.

(Answer to Q. 2)  ANS: D
Respiratory inductive plethysmography has been used extensively in research on respiratory mus-cle function. It has been used as a means of monitoring breathing patterns of patients in sleep la-boratories.

(Answer to Q. 3)  ANS: A
Because the two moving parts in the respiratory system, the rib cage and the abdomen, are ar-ranged in a series, the sum of the two displacements can be used to calculate the air volume in-spired.

(Answer to Q. 4)  ANS: A
Inductive plethysmography is based on the principle that the respiratory system moves with 2 degrees of freedom. That is, it consists of two moving parts: the rib cage and the abdomen. Dur-ing inspiration, the rib cage moves outward as the lungs expand in the thorax. Simultaneously, the abdomen is displaced outward by the downward movement of the diaphragm.

(Answer to Q. 5)  ANS: C
Respiratory inductive plethysmography has been used clinically as a means of monitoring the breathing patterns of patients in ICUs. In the ICU, it has been used primarily to identify uncoor-dinated thoracoabdominal movements that are associated with respiratory muscle fatigue or fail-ure.
