Maximal Inspiratory Pressure: Results
The sample was 69 men and 22 women with moderate to severe COPD (Table 1). Most patients were taking standard pharmacologic therapies, including inhaled p-agonists, oral (3-agonists, and methylxan-thines. Nine were using home oxygen. Ten were currently smoking, one had never smoked, and the remainder had quit smoking. The sample was middle class as indicated […]
Maximal Inspiratory Pressure: Data Analysis
The Pimax was defined as the largest negative pressure generated at the mouth and maintained for at least 1 full second. A minimum of five technically satisfactory trials were conducted for each test and data w^ere discarded if there was an air leak around the mouthpiece or if the pressure was held for less than […]

Maximal Inspiratory Pressure: Method
Maximal inspiratory pressure (Pimax) is commonly used to measure inspiratory muscle strength. It reflects the force-generating ability of the combined inspiratory muscles during a brief quasi-static contraction. The Pimax test is simple to perform and usually measured during a single test session with several trials. However, reliability has not been fully addressed in the research […]
