Pulmonary Function Studies

Interfering Factors

The aging process can cause decreased values (FVC, DCOL) depending on the study done.
Inability of the patient to put forth the necessary breathing effort affects the results.
Medications such as bronchodilators can affect results.
Improper placement of the nose clamp or mouthpiece that allows for leakage can affect volume results.
Confusion or inability to understand instructions or cooperate during the study can cause inaccurate results.
Testing is contraindicated in patients with cardiac insufficiency, recent myocardial infarction, and presence of chest pain that affects inspiration or expiration ability.
Exercise caution with patients who have upper respiratory infections, such as a cold or acute bronchitis.
