Learning Objective 1: the IMT device to shorten the weaning process
Learning Objective 2: increase the chance of successful extubation for the patients with respiratory failure and intubated with ventilators in the ICUs
Title: The effect of pressure threshold inspiratory muscle trainer on respiratory function: The application for patients with respiratory failure in ICUAim: The purpose of the study is to prevent muscle fatigue for intubated patients with respiratory failure using a pressure threshold inspiratory muscle trainer (IMT).
Method: This study adopts the quasi-experimental research design. The natural settings of two intensive care units in a medical center in southern Taiwan are set as the experimental and control units. The patients who are intubated are selected into either units based on the order on the waiting list. After the permission of the in-charge attending physicians, and patients or family, the patients who, in the control unit, meet the inclusion criteria will receive the general weaning process (i.e., T-piece trial 2 hours daily). In addition to the general weaning process, the experimental group will be given the intervention with IMT, 30% of case’s Pimax, 20 minutes daily for 7 days. For the reason of safety, during the training process, blood pressure, respiratory rate, and peripheral oxygenation measured by pulse oximeter will be recorded. Also, the levels of Pimax and RSBI in both groups before and after intervention will be obtained. Result: The study will be started in February, 2010. The change of Pimax and RSBI in both experimental and control group before and after IMT intervention will be analyzed, after controlling the confounding variables such as the severity of illness. The results will provide the evidences of using the IMT device to shorten the weaning process and increase the chance of successful extubation for the patients with respiratory failure and intubated with ventilators in the ICUs.
