Question

1. If this experiment was completed in Denver Colorado (PB 631 mmHg) the parameters could be compared with our results by corecting the estimated parameters: a) None of these ansiwers b) 100% relative humidity c) Atmospheric Temperature and Pressure, Saturated (ATPS). d) Body Temperature and Pressure, Saturated (BTPS) e) Standard Temperature and Pressure, Dry (STPp) 2. The concentration of in expired ar a single expitation. a) CO2.. is initially low and then falls even lower during b) 02....... is initially low and then rises during c) 02 d) CO2.. . . is initially about zero and then rises during e) 02 is constant throughout is initially low and falls to zero during 3. The rate of oxygen consumption of cells (VO2) in a person at rest estimated from the analysis of expired air a) is usually less than the rate of 02 consumption by the body. b) is usually greater than the rate of 02 consumption by the body. c) equals the rate of 02 uptake in the lungs. d) assumes that all the O2 in the alveoli diffuses into the blood stream during mspiraton. e) is about 2 L min 4. The highest PO2 occurs: a) in the alveoli at the start of inspiratiorn. b) in venous blood. c) in the trachea at the end of expiration. d) in the alveoli at the end of inspiration. e) in the trachea at the end of inspiration.

Explanation / Answer

1 : C (Atmospheric temperature and pressure saturated) ATPS

2: D

3: D

4 : D ( at the end of inspiration the dead space contains saturated air, PO2 = 150 mmHg)

5: c (tidal volume multiplied by raspiratory rate)

6 : D
