blow.
Note: You can view the results as either a Volume/time graph or a
Volume bar graph by selecting the relevant tab.
The VC test can be performed using two methods. Read either of the
following instructions to the subject so that testing is performed
properly:
Method 1:
a. Sit upright, fit the nose clip and relax.
b. Hold the unit, keeping it away from your mouth.
c. Inhale as deeply as possible, hold your breath, then insert
the mouthpiece carefully into your mouth, not like a trumpet,
but clamping it gently between your teeth.
d. Seal your lips around the mouthpiece and keep your tongue
down.
e. Blow out as long as possible. Keep blowing until all air is
expelled. It is vital that the operator encourages to subject
to keep blowing to ensure all air is squeezed out.
f. Listen for two beeps. This indicates that Vitalograph In2itive
is ready for the next blow.
Method 2:
Note: Method 2 can only be used when the Volume/Time (V/t) graph
is selected as the display option. This method cannot be used when
the Volume bar graph is selected as the display.
a. Sit upright, fit the noseclip and relax.
b. Insert the mouthpiece carefully into your mouth, not like a
trumpet, but clamping it gently between your teeth.
c. Seal your lips around the mouthpiece and keep your
tongue down.
