ABSTRACT
Background: Mechanical ventilation is a lifesaving modality but is often associated with high anxiety and agitation which may lead to high cost treatment and complications.
Objectives: To estimate the effect of the nature-based sounds (NBS) on physiological stress responses (heart rate, respiratory rate, blood pressure) in patients under mechanical ventilation support. Design: randomized controlled trial.
Methods: The data was collected from October 2016 to August 2017. One twenty subjects were randomly assigned to either the experimental or control group. Subjects in the experimental group listened to nature based sounds played via media player through head phones and subjects in the control group were also provided headphones but no sounds were played. Physiological stress responses such as heart rate, respiratory rate, systolic and diastolic blood pressure were assessed through bed side cardiac monitor at baseline, 15th, 30th, 45th, 60th min and 30 min after the intervention (NBS).
Results: There was a significant reduction in physiological stress responses in the intervention group.
Conclusion: Nature based sounds (NBS) may have a calming effect on physiological stress responses and hence further stabilising the patient overall.
Key words: Mechanical ventilation, Nature-based sounds (NBS), stress, physiological stress responses
