RESPIRATORY MUSCLE TRAINING AT WEANING FROM IMV: AN INTEGRATIVE REVIEW

Abstract

Objective: To evaluate the repercussions of respiratory muscle training on weaning IMV. Methodology: The present study is an integrative review study, with a survey carried out in the following databases: the National Library of Medicine, the National Center for Biotechnology Information (PUBMED), and Latin American and Caribbean Literature on Health Sciences (LILACS). The search for articles took place from August to November 2023, with the following descriptors: weaning, respiratory muscle training, and inspiratory muscle training, and used as follows: PUBMED, the descriptors "weaning", "respiratory muscle training"; and in LILACS, the descriptors "inspiratory muscle training", "weaning" were used. On both platforms, he used the Boolean operator "AND". Results: Respiratory muscle training is essential for maintaining and reestablishing the power and strength of the respiratory muscles, especially in patients who remain on invasive mechanical ventilation (IMV) for long periods so that the muscles can perform their function efficiently. The protocols for carrying out the training are varied in load intensity, sets, and repetitions, the 7 selected articles showed consequent benefits of respiratory muscle training in the weaning process, as well as in variables that influence its reduction, such as MIP, improvement of FVC, reduction of SRRI and dyspnea. Conclusion: Given the arguments presented, it can be seen through the study that respiratory muscle training (RMT) promotes positive effects on weaning from invasive mechanical ventilation (IMV) since it promotes the gradual improvement of inspiratory muscle strength, and respiratory patterns, oxygenation, MIP, FVC and reduction of weaning duration.
