Introduction:

one of the main effects of invasive mechanical ventilation is injury to the respiratory muscles, specifically the diaphragm. In which structural and functional alterations can occur that partially or totally modify its function. During mechanical ventilation, a process of disuse atrophy of said muscle occurs. Therefore, the clinical utility of measuring diaphragmatic muscle strength is important to know if the patient has the ability to activate the protective mechanisms of the airway to achieve successful extubation and removal of the mechanical ventilator in the shortest time possible.

Objective:

describe the measurement of muscle strength as a predictor of extubation in intensive care units.

Material and methods:

a literature review was carried out, carried out between 2011 and 2022.

Results:

patients who are subjected to prolonged mechanical ventilation generally develop a diaphragmatic muscle disorder, becoming a problem for the weaning, for it is important know the methods of measuring muscle strength.
