PFT'S review 7-3 Flashcards
(46 cards)
Steadwells has two types known as
wet and dry
Wet steadwell
belt flows
used today
dry steadwell
belt rolls over itself
right spirometer measures ?and used at?
measures vt and mv, used at bedside for pft
heated wire flow sensors has a
cooling effect
ultrasonic flow sensors has a
high frequency sound wave
recommendations for spirometers set by
national lung health
high peak flow for adults is
850lpm
low flow kids
400lpm
plethsmography has
2 types pressure and flow
inversed to pressure
Bellows spirometer
wedge spirometer
accordion type-horizontal/vertical
Turbine
directly measures gas volume
pitot flow
pressure of gas flowing against small tubes is related to gas density and velocity
flow sensor spirometer advantages
less expensive
easier to clean and disinfect
measure diffusion capacity
main goal is
standardize spirometry
promote early diagnosis
peakflow must be
acceptable and replicable
5% variability
constant volume fop pleth is
pressure
variable volume in pleth is
flow
Boyle’s Law is described as
A principle that describes the relationship between the pressure and volume of a gas at constant temperature
both pressure and flow plethsmography use?
pneumotachometer and mouth pressure transducer
how do you know if the pt is in steady state?
hr remains same for 1 min
Borg scale
-Standard means to evaluate client perception of exercise effort.
Disease process indicators for pulmonary rehab are
cbabe
lung resection/transplant
NmD
Ancillary groups
better breathers
