Flashcards in chapter 1 indication for spirometry Deck (27):
1

airway function test

non forced spirometry
forced spirometry
maximal voluntary ventilation
maximal inspiratory/expiratory pressure
airway resistance and compliance

2

lung volumes and ventilation test

functional residual capacity
total lung capacity
minute ventilation and dead space
distribution of ventilation

3

pulmonary function test

diffusing capacity
blood gases
cardiopulmonary exercise testing
metabolic measurement

4

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

5

spirometry indication 2

classify the disease:
obstructive , restrive, and mixed

6

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

7

spirometry indication 4

spiromotry can determine beneficial or negative effect of therapy
bronchodilator or steriod
cardiac drugs
lung resection
pulmonary rehabilitation

8

spirometry indication 5

assess the risk for surgical procedure
lung resection
thoracic procedure
abdominal procedure

9

spirometry indication 6

evaluate disability or impairment
social securing or other compensation
legal or insurance claims

10

detrmining rv, tlc, frc

nitrogen washout
helium dilution- rebreathing of 10% HE until equilibration is reached
plethmography - boyle law
x-ray planemetry

11

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.

12

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

13

DLCO is sensitive

used to track in interstitial and restrictive lung disease

14

ventilation is best measured in CO2

vco2/ve*0.863

15

Pao2

partial of oxygen in plasma
measure in Torr
a small fraction of the actual oxygen transported by blood

16

co-oximetry better indicator of

oxygen transport
functional hemigobin
dysfunctional hemiglobin

17

what is measure CPX test

12 lead ECG
non-invasive blood pressure
pulse ox
pulmonary function parameter: Ve, vo2 consume, Vco2, RQ

18

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

19

vo2 consumed and vco2 produced

RQ and determines if patients is over fed or under fed

20

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

21

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

22

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

23

CBABE

cystic fibrosis
bronchitis
asthma
bronchieatisis
emphysema

24

paint

pleural disease
alveolar disease
interstitial disease
neuromuscular disease
thoracic disease

25

patient preparation

provide pre-test interaction
withhold medicate if indicated
hold on smoking and coffee
hold on exercise
wear loose cloth
don't eat a lot

26

patient intake

brief history of symptoms
vital sign
physical examination

27

supporting testing

x-ray
blood work
