Abstract
The two self-explanatory tests used to assess the respiratory pressures are the maximal inspiratory pressure (MIP) and the maximal expiratory pressure (MEP).These pressures are generated by the respiratory muscles during a forceful inspiration and expiration, respectively.

Notes
- 1.
*MIP and MEP are sometimes referred to as PImax and PEmax, respectively.
- 2.
- 3.
‡Bilateral tetanic stimulation can give maximal Pdi but is uncomfortable and only used for research.
- 4.
§This reduction is caused by the effect of the increasing frequency of breathing on the lung units that are recruited. As the frequency of breathing increases, the lung units with more rapid frequency response, i.e., shorter time constant, are recruited and these units are less compliant.
