Comparison of the Effects of Inspiratory Muscle Training Methods in Mechanically Ventilated Patients

"During the first week of training, ventilator trigger sensitivity will be initiated at 20% of the patient's baseline MIP (NIF). Patients will train for 5 minutes twice a day for the first days. As the training progresses, the triggering sensitivity will be gradually increased to 30% and 40% of the initial MIP and the duration will be increased up to 30 minutes. During the training sessions, participants will be elevated to a position similar to the Semi-Fowler position at an angle of approximately 45°. Vital signs will be monitored regularly.~In addition, conventional chest physiotherapy consisting of respiratory control, diaphragmatic breathing, costal expansion exercises, postural drainage, effective coughing, in-bed ROM exercises and mobilization will be applied twice daily."

"The IMT (Inspiratory Muscle Training) with device will commence at 20% of the value obtained from the NIF (Negative Inspiratory Force) measurement or the lowest pressure setting, depending on the patient's tolerance. The duration and intensity will be gradually increased. Once the participants are disconnected from the mechanical ventilator, the IMT device will be connected to the T-tube via a catheter mount with a Catheter Mount. Patients will be instructed to breathe against the resistance set on the IMT device. After completing 8 repetitions, the patient will be allowed to rest for a few minutes. This routine will be repeated for a total of 3 sets of 8 repetitions.~In addition, conventional chest physiotherapy consisting of respiratory control, diaphragmatic breathing, costal expansion exercises, postural drainage, effective coughing, in-bed ROM exercises and mobilization will be applied twice daily."
