pulm mechanics Flashcards
VE
minute volume
minute volume device
spirometer
normal minute volume
5-10L
minute volume test
breathe normally thru mouth piece for one minute while counting their RR
Vt
tidal volume
normal vt
5-7ml/kg PBW
tidal volume equation
VE= RR x VT
tidal volume steps
calculate predicated range with PBW # x 5 & 7 and calculate actual VT # see if in range
PEFR
peak expiratory flow rate
PEFR device
PEFR Meter
PEFR normal range
600 L/min
inhale deeply and forcefully exhale, quick and hard
PEFR– check 15%
MIP
maximal inspiratory pressure
MIP normal range
f-> better than 70 and m-> better than 100
MIP steps
connect circle/tube piece to pressure manometer and dispiro, then exhale completely and inhale as deep as possible, hard and fast, 15%
MEP
maximal expiratory pressure
MEP steps
connect circle/tube piece to pressure manometer and dispiro, then inhale completely and exhale as deep as possible, hard and fast, 15%
MEP normal range
f-> greater than 100 m-> greater than 150
SVC
slow vital capacity
SVC normal range
60-80ml/kg PBW
svc device
spirometer
svc steps
inhale as deeply as possible then exhale slow and as long as possible, convert # to mL (decimal to right 3)
