Physiology

Question 1

Amount of gas moved in normal resting inspiratory effort

Answer 1

Tidal volume

Question 2

Effect of exercise on VO2Max

Answer 2

Exercise increases VO2max

Question 3

Central vs peripheral chemoreceptors are sensitive to what?

Answer 3

Central sense increase in CO2 and peripheral senses decrease of O2

Question 4

Volume of gas inhaled or exhaled per minute

Answer 4

Minute volume

Question 5

To be able to clear secretions need at least how much of a peak cough flow

Answer 5

3L/s

Question 6

Fick equation

Answer 6

VO2max = (HR x SV) x AVO2 difference

Question 7

VO2 max

Answer 7

Amount of oxygen used in one minutes of maximal exercise

Question 8

Obstructive versus restrictive FEV1/FVC

Answer 8

Obstructive: FEV1/FVC is decreased because FEV1 decreases.
Restrictive: FEV1/FVC is normal or increased because both decrease at the same rate

Question 9

Amount of gas in the lungs at the end of maximal expiration

Answer 9

Residual volume

Question 10

Amount of gas within the lungs at the end of maximal inspiration

Answer 10

Total Lung capacity

Question 11

Units of VO2max

Answer 11

mL O2 in 1min/kg body weight

Question 12

Five accessory muscles of inspiration

Answer 12

Sternocleidomastoid, trapezius, pectoralis major, External intercostal, scalene muscle

Question 13

Vital capacity measured with the subject exhaling as rapidly as possible

Answer 13

Forced vital capacity

Question 14

Amount of air expelled in the first second of FVC

Answer 14

forced expiratory volume in one second FEV1

Question 15

Amount of gas in the lungs at the end of normal expiration

Answer 15

Functional residual capacity

Question 16

Where does voluntary control of respiration originate from

Answer 16

Medulla oblongata

Question 17

Accessory muscle for expiration

Answer 17

Internal Intercostal

Question 18

Mortality rate and FEV1

Answer 18

FEV1 < 750mL. 30% die within one year and 50% within three years

Question 19

Primary expiratory muscle

Answer 19

Abdominal muscles

Question 20

Primary muscle of respiration during inspiration

Answer 20

Diaphragm
