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 ]
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.)
Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
Some reports state that participation at USAF fitness centers is up 30 percent since the new program was established. [4] 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.
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.
The PFT is a collective measure of general fitness Marine Corps-wide, and consists of three events: [3] Dead-hang pull-ups or push-ups; Abdominal crunches or planks; Three-mile run (or 5000-meter row, if requirements are met) On October 1, 2008, the Marine Corps introduced the additional pass/fail CFT to the fitness requirements.
In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...
The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) and peak flow measurement, [1] is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.
