The Effect of Passive Range of Motion Exercises on Hemodynamic Parameters of Mechanically Ventilated Patients

Background: Mechanically ventilated patients are often confined to bed rest for long periods which make them at high risk for impairment in different body systems. Evidence suggests that passive range of motion exercise for mechanically ventilated patients is a safe and effective intervention that can have a significant impact on patients' clinical outcomes. Aim: The aim of this study was to investigate the effect of passive range of motion exercises on hemodynamic parameters of mechanically ventilated patients. Method: The study has a quasi-experimental research design with a convenience sample of 112 adult mechanically ventilated patients from the anesthesia and neurosurgery intensive care units at Mansoura University Hospital in Egypt. Data were collected using patient's hemodynamic parameters assessment tool. Results: Statistically significant differences were noted between the intervention and control groups regarding the mean of physiological parameters including the respiratory rate, oxygen saturation, heart rate, systolic and diastolic blood pressure, and mean arterial pressure across the four measurement time points including baseline measurement, and 5, 20, and 60 minutes after exercises (P<0.05). On the contrary, no statistically significant changes were detected in the central venous pressure measures between the two groups (P=0.929). Conclusion and Recommendations: Passive range of motion exercises are considered as an effective method for stabilizing physiological parameters among mechanically ventilated patients. Hence, it can be incorporated as an adjunct intervention in the routine nursing care of mechanically ventilated patients. Further large-scale studies are required to contribute to the evidence-based care and support using this intervention.
