Enhancing pulmonary function and arterial blood gas readings through immediate chest physiotherapy among extubated patients in ICU

Abstract

Objective: To examine the effect of immediate chest physiotherapy (ICPT) on pulmonary func- tion and arterial blood gases among extubated patients. Method: This prospective study enrolled patients aged 20–60 years who had been intubated for 48 h. They were randomly assigned to either a control or study group. The study group received ICPT by trained critical care nurses and physiotherapists, which included early mobilization, breathing exercises and airway clearance. The control group received standard nursing chest care (positioning, oral and endotracheal suctioning) without ICPT. Researchers evaluated partic- ipants using pulmonary function tests, arterial blood gas tests and mechanical ventilation parameters. Results: The study enrolled 70 patients. There were no significant differences in the sociodemo- graphic characteristics and medical data before intubation between the two groups except for preparatory education. After extubation, the vital capacity was significantly higher in the study group compared with the control group. There were also significant differences between the two groups in other lung function tests and arterial blood gas tests. After extubation, the total lung capacity, functional residual capacity and residual volume were significantly higher in the study group compared with the control group.
