2)
Breathe through the airflow
transducer, following the proper
procedure defined to the right.
Hints for obtaining optimal data:
a)
Keep the Airflow Transducer upright at all times.
b)
Always insert on and breathe through the side of the
SS11LA airflow transducer labeled “Inlet.”
c)
Always use a nose clip when breathing through the
airflow transducer and secure a tight seal with the mouth
so that air can only escape through the airflow
transducer.
d)
Always begin breathing normally through the airflow
transducer prior to the beginning of the recording and
continue past the end of the recording.
e)
If starting the recording on an inhale, try to end on an
exhale, and vice-versa. This is not absolutely critical,
but will increase the accuracy of Airflow to Volume
calculations.
f)
The Subject must try to expand the thoracic cavity to its
largest volume during maximal inspiratory efforts. (The
Subject should wear loose clothing so clothing does not
inhibit chest expansion.)
g)
During recording of FEV, the Subject should attempt to
exhale as quickly as possible into the mouthpiece.
h)
During recording of MVV, the Subject should attempt
to exhale and inhale as quickly and deeply as possible.
Breathing rates should be faster than 60 breaths/minute
or greater than 1 breath/second for the best results. The
breathing needs to be maintained for 12-15 seconds.
