3 L syringe
+- 3.5 % or 105 mL
do not need to vary flow rates
Forced vital capacity
Maximal inhalation (TLC) a blast of exhalation continue complete exhalation
communication and cooperate are essential
practice until you are perfect
and know your equipment
ATS position
use of nose clips or manual occlusion is recommended
sitting position is preferred, the maneuver may also be performed standing
AARC clinical of a nose for clip
nose clip for all spirometric maneuver is strongly encourage
When performing pulmonary function studies
each effort must be maximal
there should be no leaks through the mouthpiece or nose
start test criteria
back extrapolation should be less than 5% or 150 mL whichever is greater
blow hard from TLC after about 3 Seconds
End test criteria
patient reaches exhaustion and watch for signs of syncope
no change in flows for 1 seconds and exhalation time is met
exhaltion and children older then 10 should have exhalation 6 seconds
children less 10 years is 3 seconds
Addition criteria
no coughing in first second
no glottis closure influencing
no early termination of the test
incosistent effort throughout the test
FVC and FEV1 should be?
should be plus or minus 0.150 L
if the test criteria is not met continue performing maneuver?
up to 8 test maximum
