An incentive spirometer is a handheld medical device used to help patients improve the functioning of their lungs. By training patients to take slow and deep breaths, this simplified spirometer facilitates lung expansion and strengthening.
John Hutchinson was born in 1811 in Ryton, a village near Newcastle upon Tyne, where his father was a yeoman farmer and colliery manager. Hutchinson initially trained as a surgeon in the North-East, but following his father’s death in 1834, he went to London and completed his training at University College, passing the examination for MRCS in 1836.
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]
Doing spirometry. 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.
In 1960, the European Community for Coal and Steel (ECCS) first recommended guidelines for spirometry. [7] The organization then published predicted values for parameters such as spirometric indices, residual volume, total lung capacity, and functional residual capacity in 1971. [ 8 ]
The measurement of peak expiratory flow was pioneered by Martin Wright, who produced the first meter specifically designed to measure this index of lung function. Since the original design of instrument was introduced in the late 1950s, and the subsequent development of a more portable, lower cost version (the "Mini-Wright" peak flow meter ...
