chapter 1 indication for spirometry Flashcards
airway function test
non forced spirometry forced spirometry maximal voluntary ventilation maximal inspiratory/expiratory pressure airway resistance and compliance
lung volumes and ventilation test
functional residual capacity
total lung capacity
minute ventilation and dead space
distribution of ventilation
pulmonary function test
diffusing capacity
blood gases
cardiopulmonary exercise testing
metabolic measurement
lung indication for spirometry #1
detect the presence of absence of lung disease
oftern performed as screening procedure and often is very first state that indicates pulmonary problem
spirometry is a Gold standard for :
National lung health education program
national heart ,lung and blood institute
spirometry indication 2
classify the disease:
obstructive , restrive, and mixed
spirometry indication # 3
quantify the extent of known disease on lung function
can be used to evaluate COPD, asthma, cystic fibrosis, interstitial disease
measure effects of occupation or environmental exposure
spirometry indication 4
spiromotry can determine beneficial or negative effect of therapy bronchodilator or steriod cardiac drugs lung resection pulmonary rehabilitation
spirometry indication 5
assess the risk for surgical procedure
lung resection
thoracic procedure
abdominal procedure
spirometry indication 6
evaluate disability or impairment
social securing or other compensation
legal or insurance claims
detrmining rv, tlc, frc
nitrogen washout
helium dilution- rebreathing of 10% HE until equilibration is reached
plethmography - boyle law
x-ray planemetry
how the DLCO done
the patient exhales to RV and inhales the CO to total lung capacity and holds breath for 10 sec and exhales back to RV
the concentration of inhaled is known and exhaled is measured and the difference is diffused into blood.
the purpose to DLCO is to
ideally we would like to measure oxygen diffusion
the CO has 210 times affinity for hemoglobin when compared with oxygen
DLCO is sensitive
used to track in interstitial and restrictive lung disease
ventilation is best measured in CO2
vco2/ve*0.863
Pao2
partial of oxygen in plasma
measure in Torr
a small fraction of the actual oxygen transported by blood
co-oximetry better indicator of
oxygen transport
functional hemigobin
dysfunctional hemiglobin
what is measure CPX test
12 lead ECG
non-invasive blood pressure
pulse ox
pulmonary function parameter: Ve, vo2 consume, Vco2, RQ
measure of Vo2 and vco2 produced
resting state early AM
post absorptive no food or beverage
quite dark room
ideally want the basal metabolic state
vo2 consumed and vco2 produced
RQ and determines if patients is over fed or under fed
ist indication for lung volume measurement
assess severity of lung disease
differentiate between obstructive and restrictive disease
asses the response to therapy:
Bronchodilators
lung transplantation
radiation or chemotherapy
make preoperative assessment
determine or evaluate disability
assess gas trapping by comparing plethmographic and dilution lung volumes
standardize other lung function measurement
indication for DLCo
evaluate pulmonary involvement of systemic disease
evaluate osbtructive lung disease
evaluate cardiovascular disease
quantify disability associated with inertial lung disease
evaluate pulmonary hemorrhage, polycethmia, or left to right shung
indication for abgs
evaluation of lung function
determine the need of supplement o2
monitor ventilatory support
document the severity or progression of known pulmonary disease
provide data to correct other pulmonary test
CBABE
cystic fibrosis bronchitis asthma bronchieatisis emphysema
