Chapter 4 Performing Spirometry Tests
Welch Allyn CP 200 Spirometry Option
Preparing the Patient
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 any more out” — 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.
•
Use of a nose clip is optional. Patients may also pinch their noses.
•
Place your lips and teeth around a new transducer, sealing their lips tightly around
the transducer. Grip slightly with your teeth in the groove. If you need to hold the flow
transducer in your hand, keep fingers away from the screen on the back.
Blocking even part of this screen creates back-pressure, which makes the
percent prediction value very high (as much as 200% or 300%), and you will
need to discard the data.
•
Avoid bending forward as you blow. This also creates back-pressure.
•
Keep your tongue away from the flow transducer to avoid blocking it.
•
Keep your chin up so as not to restrict the airway.
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.
WARNING
Patients should not bite on the flow transducer. Biting could result in
sharp edges, which could injure the mouth.
