Applied Physiology for Sedation

Question 1

what is air flow driven by

Answer 1

pressure gradients

Question 2

what happens when the alveolar pressure is less than the atmospheric pressure

Answer 2

inspiration

Question 3

what happens when the alveolar pressure is greater than the atmospheric pressure

Answer 3

expiration

Question 4

what is tidal volume

Answer 4

air moving in and out of lung during quiet breathing

Question 5

what is reached if you force inspiration to is maximum

Answer 5

inspiratory reserve volume

Question 6

what is residual volume

Answer 6

the volume left at the core of the lung after maximum exhalation

Question 7

what happens in a patient with obstructive lung disease

Answer 7

reduced vital capacity and slowed down exchange rate

Question 8

what happens in restrictive lung disease

Answer 8

small volumes exchanged and occur at a similar rate to normal patient

Question 9

what is pulmonary gas exchange

Answer 9

gas exchange occurring between the alveolar air and the pulmonary capillary
