Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack.
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.
The PFT can be released in a variety of ways, depending on the application, and may be as simple as spraying it into the air. Samples are then collected at set times and locations, and either taken to a laboratory for analysis, or analysed in the field. Analysis of the samples typically involves three parts; preparation, chromatography and ...
Diffusing capacity of the lung (D L) (also known as transfer factor) measures the transfer of gas from air in the lung, to the red blood cells in lung blood vessels. It is part of a comprehensive series of pulmonary function tests to determine the overall ability of the lung to transport gas into and out of the blood.
The Physical Fitness Assessment consists of a Body Composition Assessment (BCA) and a Physical Readiness Test (PRT), which includes a timed cardio event consisting of 1.5-mile (2.4 km) run/treadmill or a 500 yd (460 m) swim (or an alternate cardio consisting of 12-minutes on a stationary bike), timed curl-ups, and timed sit-ups.
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 ...
