Question 1 (1 point)

In the experiment you completed on the analysis of expired air the subjects expired air was collected into a Douglas bag. The volume of the bag was measured at ATPS. Which conversion factor would you use to convert the value to BTPS?

Question 1 options:

	STPD from BTPS
	STPD from ATPS
	BTPS from ATPS
	BTPS from STPD

Question 2 (1 point)

During normal quiet breathing, the concentration of oxygen in the conducting portion of the airways at the beginning of inspiration is initially _______ and then ___________ during inspiration.

Question 2 options:

	low..............decreases
	low..............increases
	high..............does not change
	high..............increases

Question 3 (1 point)

The respiratory quotient (RQ):

Question 3 options:

	is the ratio of O2 produced to CO2 consumed.
	the ratio of CO2 produced to O2 consumed.
	Changes with food stuff utilized as the fuel source.
	when carbohydrate is being utilized is 1 meaning that for every molecule of oxygen consumed, one molecule of carbon dioxide is produced.
	Both B and D are correct

Question 4 (1 point)

The following statements are comparing breathing holding times under different conditions. Choose the correct statement.

Question 4 options:

	Breath holding at TLC (from RV) breathing room air should result in a longer breath hold time than TLC (from RV) breathing a gas mixture of 95% O2 and 5% CO2
	Breath holding at TLC (from RV) breathing room air after a period of hyperventilation should result in a longer breath hold time than TLC (from RV) breathing a gas mixture of 95% O2 and 5% CO2
	Breath holding at TLC (from RV) breathing 100 O2 should result in a longer breath hold time than TLC (from RV) breathing a gas mixture of 95% O2 and 5% CO2
	All of the above are correct.

Question 5 (1 point)

In the experiment where the subject collected their expired air into a bag, choose the correct statement.  

Question 5 options:

	The carbon dioxide levels will be higher in the atmospheric air than the alveolar air.
	The carbon dioxide levels in the room air and alveolar air were similar.
	Expired air contains no oxygen.
	The carbon dioxide levels in the anatomical dead space will be higher at the end of expiration compared to the end of inspiration.

Question 6 (1 point)

A person who has a tidal volume of 465 mL/breath, a respiratory rate of 18 breaths / minute, and an anatomical dead space volume of 175 mL will have an alveolar ventilation rate of:
