Presiones inspiratoria y espiratoria máximas: Recomendaciones y procedimiento

Abstract

The measurement of maximal inspiratory (MIP) and expiratory (MEP) pressures assess the strength of the respiratory muscles. These test are a simple, quick, and noninvasive. It consists that the patient must generate peak inspiratory (from residual volume) and expiratory pressure (from total lung capacity) against an occluded system. MIP assesses the diaphragmatic strength; while MEP assess the intercostal and abdominal muscles. Maximum respiratory pressures are of great clinical utility in the diagnosis and monitoring of diseases affecting the respiratory muscles. In order to improve quality and facilitate the realization of the measurement of MIP-MEP, we review international recom- mendations on this procedure and issue local guidelines that contribute to a better standardization process.
