Information on the parameters measured by Spirobank Oxi
Spirometry tests
PEF
is the maximum speed of the air when you exhale as hard as possible after filling your
lungs completely.
FEV1
is the volume of air expelled during the first second of the same exhalation.
FVC
is the volume of air expelled during the total exhalation.
FEF2575
is the average flow between 25% and 75% of the total volume of air expelled during
the total exhalation (FVC).
FEV6
is the volume expired in the initial 6 seconds of the test.
In addition to these parameters, the following parameters are also calculated in the
F/V
version:
PIF
is the maximum speed of the air when you inspire as hard as possible after the exhalation.
FIV1
is the volume of air inspired during the first second after the exhalation.
FIVC
is the volume of air inspired during the total inspiration.
FEF25
is the Forced Expiratory Flow at 25% of FVC
FEF50
is the Forced Expiratory Flow at 50% of FVC
FEF75
is the Forced Expiratory Flow at 75% of FVC
EVol
is the
back Extrapolated Volume
FEV05
is the
Forced Expiratory Volume expired in the initial 0,5 seconds of the test
FEV075
is the
Forced Expiratory Volume expired in the initial 0,75 seconds of the test
FEV2
is the
Forced Expiratory Volume expired in the initial 2 seconds of the test
FEV3
is the
Forced Expiratory Volume expired in the initial 3 seconds of the test
FET
is the
Forced Expiratory Time and
measures the length of the expiration in seconds
PEF Time
is the
Time to achieve 90% of the PEF
For each of these parameters, the result is a number shown on the smartphone screen.
A high number (associated with a green light) usually means that the air is moving easily
through your lungs. If you have asthma (or another respiratory disease) and have an
obstructive episode, the air cannot generally be expelled as forcefully as possible, so your
parameters will be lower.
