Inspiratory muscle training
After the surgical procedure, the patients were referred to the Intensive Care Unit (ICU) and received care according to the institution’s protocol.

Patients underwent inspiratory muscle training with a linear pressure load device (PowerBreathe Knectic Series®, HaB International, UK), with a load equivalent to 40% of the Pimax, performing 3 series with 15 repetitions8. This training was carried out twice a day, until the day of hospital discharge in association with the usual care of the physiotherapy team.
Control Group (CG) - Patients were managed exclusively according to the usual routine, which consists of applying non-invasive ventilation, breathing exercises, kinesiotherapy, cycle ergometry and stimulating walking.
