Spirometry Data Acquisition Screen (Test Screen)
By default, the FVC button will be selected. For a Pre-BD test, make sure the words Pre-
Bronchodilator appear in the blue box in the middle of the screen. Also notice that the
Pre and FVC buttons are bold. Do not click the Start New Test button until the patient
is ready.
Once the patient is prepared, you must explain the full procedure of the test. Tell the
patient to take 2 or 3 normal tidal breaths and then to inspire as deeply as possible. After
a complete inhalation, tell the patient to place the mouthpiece in their mouth (as described
earlier) and enthusiastically encourage them to blast out the air quickly and completely.
Continue to encourage with voice and body language until a visible plateau is evident on
the Flow-Volume scale or until the program indicates that no additional flow is being
measured (displays: Inhale Now). If a full loop is required, instruct the patient to breathe
in quickly and fully to take in as much air as possible.
Demonstrate this procedure for the patient. Let the patient see the effort required for a
good test. The technician should carefully watch the entire maneuver ensuring:
 Maximal inhalation before starting
 Forced expiration - Quick, strong and without hesitation
 Continued expiration – Encourage the patient to blow out as long as possible
