8.3 Patient Procedures
To prepare patients for any spirometry test, explain the entire procedure for the type of effort
you want them to perform. Remind patients that the test is painless. Demonstrate at least one
effort for the patient.
The accuracy of a spirometry test is highly dependent on the patient's understanding and
cooperation. So, be prepared to coach and encourage the patient with your “body language”
and your words
— for example, ”Blow, blow, blow, keep blowing until you can't blow out any
more” — to ensure a good effort with reproducible results.
Instruct patients to do the following:

Loosen any tight articles of clothing that might constrict lung function, for example, a tight
belt, tie, vest, bra, girdle, or corset.

Remove any foreign objects from the mouth, including loose dentures.

The use of a nose clip is highly recommended. If used, check for proper fit.

Place lips and teeth around a new flow transducer, sealing their lips tightly around the
transducer. Grip slightly with teeth in the groove.

Keep tongue away from the flow transducer to avoid blocking it.

Keep the rear of the Flow sensor free.

Keep chin up so as not to restrict the airway.
Once the patients have the flow transducer in place, ask them to perform the effort using the
guide below for the patients’ predicted performance effort breathing instructions.
Note:
Place the mouthpiece in the patient’s mouth after stabilization.
WARNING Patients may become faint, light-headed, dizzy, or short of
breath during spirometry testing. Watch patients closely. If they
choose to stand during testing, keep a chair immediately
behind them. If there is any reason for concern, stop the test
and take proper action.
Recommendations
Practice the procedure with the patient before recording the
effort.
American Thoracic Society recommends ending recording
after eight successful FVC efforts to avoid fainting.
WARNING
Always check the interior of the flow transducer to ensure that
no foreign objects are present.
