Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [ 1 ]
The patient will be asked to take a deep breath and then blow into the mouthpiece of the spirometer as hard as you can. This is a baseline measurement. A dose of bronchodilator medication is administered by means of inhaler or nebulizer (such as 400mcg of salbutamol (also known as albuterol)).
In the Air Force, Airmen are given a score based on performance consisting of four components: waist circumference, situps, pushups, and a 1.5-mile run. Airmen can potentially earn a score of 100; a passing score is anything over 75 points. Members must complete all components unless medically exempted.
The patient is asked to put on soft nose clips to prevent air escape and a breathing sensor in their mouth forming an air tight seal. Guided by a technician, the patient is given step by step instructions to take an abrupt maximum effort inhale, followed by a maximum effort exhale lasting for a target of at least 6 seconds.
TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)
The testing events are conducted in accordance with standards detailed in Army FM 7–22: Army Physical Readiness Training. Prior to the start of each event, the standard is read aloud, followed by a demonstration in which an individual demonstrates both the correct exercise and any disqualifying behaviors which would make the exercise incorrect.
