Answer 4

IRVm tidal volume, and ERV

Question 5

FRC

Answer 5

ERV and RV

Question 6

TLC

Answer 6

IRV, vt, erv, rv

Question 7

bell factor

Answer 7

for each mm kymograph pen moves, the bell must displace a certain volume

Question 8

bell factor is used in what?

Answer 8

to convert the linear distance the linear distance the kymograph pen moves to volume a volume

Question 9

ATPS to BTPS

Answer 9

converting the value of ambient air to body temperature and saturation

Question 10

Slow vital capacity

Answer 10

make sure the patient exhales then inhales and then exhale.

Question 11

it is important that slow vital capacity should be slow becuase

Answer 11

it is usually larger and difference is usually accounted for in lung disease due to air trapping.

Question 12

during force maneuver there is

Answer 12

increased pleural pressure cause the airway to collapse and trapping gas

Question 13

restricitve pattern

Answer 13

reduction in all lung volume

notmal RV/TLc

Question 14

obstuructive pattern

Answer 14

increase in FRC and RV
Reduction in VC
RV/TLC% increase

Question 15

obstructive with air trapping

Answer 15

normal TLC
decrease VC
increase FRc
increase RV/TLC%
