Answer 5

inspired

Question 6

what does the subscript of E mean?

Answer 6

expired

Question 7

what’s the equation for minute ventilation ?

Answer 7

V (dot above) = VT x fb

minute ventilation = tidal volume x breathing frequency

Question 8

what is dead space ?

Answer 8

volume of air not participating in gas exchange

around 150mL

Question 9

what’s the equation for alveoli volume ?

Answer 9

alveoli volume = (tidal volume - dead space) x breathing frequency

Question 10

Answer 10

volume of gas in lungs after maximum inspiration

Question 11

what is vital capacity ?

Answer 11

how much air we can maximally breath out after a maximum inspiration

Question 12

what is expiratory reserve volume ?

Answer 12

amount of air in excess of tidal volume that can be exhaled with max effort

Question 13

what is residual volume

Answer 13

volume gas remaining in lungs after maximal expiration

Question 14

what is inspiratory reserve volume ?

Answer 14

amount of air in excess of tidal volume that can be inhaled with maximum effort

Question 15

what is tidal volume ?

Answer 15

amount of air exhaled or inhaled in one breath

Question 16

what is inspiratory capacity

Answer 16

max amount of air that can be inhaled following normal expiration
