Summary

Background: the objective of the present inquiry was to evaluate the weaning process in intubated older people subjected to inspiratory muscle training and to correlate the predictors of ventilatory interruption with its success.

Methods: the patients were divided randomly into an experimental group (EG, n=14; age=82±4 years) that received conventional physiotherapy plus inspiratory muscle training (IMT) with threshold IMT® and a control group (CG, n=14; age=81±6 years) that received only conventional physiotherapy. The predictors evaluates were the maximum inspiratory pressure (MIP) and the index of Tobin (IT). The protocol for muscle training consisted of an initial load of 30% MIP, which was increased by 10% daily; training was administered for five minutes, twice a day, seven times a week with supplemental oxygen for the entire period from the decision to wean up to extubation.

inspiratory muscle training

Protocol of inspiratory muscle training using threshold IMT®: After the MIP was measured, inspiratory muscle training was initiated. The Threshold-IMT® device of a linear pressure load produces a resistance to inspiration through the use of a flow-independent one-way valve. During expiration there is no resistance because the unidirectional valve opens, while during inspiration the valve closes, becoming "hard" due to the resistance of the spring. The suggested protocol was: initial load of 30% of the M24, increasing daily by 10%, with training for five minutes, twice a day, seven times a week in the period from the beginning of the weaning from the MV until the extubation of the patient. An essential factor was the use of supplemental oxygen (O2) as needed by the patient. The patients were in DD with fowler 45º.
