Pulmonary  Function Test:

Pulmonary functions  tests (PFTs) provide information about a clients manifestation by measuring lung volumes, lung mechanics, and diffusion capabilities of the lungs. PFTs peribrmed in a pulmonary function laboratory can measure respiratory volumes and capabilities. On the other hand, PFTs done outside of a laboratory are modified to include ventilation tests of forced expiratory volume, vital capacity, and maximal voluntary ventilation measures. A handheld measure of  inspiratory flow is called a peak flow. Many clients with asthma use a peak  flowmeter at home to monitor changes in their condition and responses to treatment.

Education about the purpose, procedure, and implications of the  test  is performed by  the nurse and reinforced by the examiner. Explicit  instructions of each maneuver are given during the  testing. Instruct clients that  it  is  normal to feel short of breath after the test. Clients should not  smoke or use a bronchodilator 6 hours before undergoing a PFT.
