Hans Rudolph, Incorporated, was founded by Hans Rudolph, who in 1938 began designing pulmonary function testing (PFT) equipment. One of his most successful devices was a PFT high velocity valve. Today, the company is a designer and manufacturer of various supplies and pieces of equipment used in various healthcare settings.
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.

1859 E. Smith developed a portable spirometer, which he used to measure gas metabolism. 1866 Henry Hyde Salter (1823-1871) added a kymograph to the spirometer in order to record time while obtaining air volumes. 1879 Gad J. published a paper entitled "Pneumatograph" that described a machine that allowed the recording of lung volume changes.
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.
