Effect Of Body Position On Peak Expiratory Flow Rate And Physiological Responses In Post Operative Cardiac Surgery Patients

Abstract

Objectives: To study the Effect of Body Positions on Peak Expiratory Flow Rate and Physiological Responses in Post Operative Cardiac Surgery Patients
Settings: ICU CTVS Department, Pushpanjali Crosslay Hospital (presently Max Hospital, Vaishali)
Methods: Cross over study design was used. 40 subjects were randomly selected from both male and female groups based on the inclusion and exclusion criteria of the study. Subjects will receive different Body Positions (Supine, Three-Quarter Sitting, Long Sitting and Sitting with Back Rest Vertical) randomly for 20min. With a gap of 5min interval between each position and PEFR and Physiological Responses were noted.
Result: Demographic data was analyzed by comparing means of descriptive. The mean of age is 58.97 ± 8.51 in all Body Positions (Supine, Three-Quarter Sitting, Long Sitting and Sitting with Back Rest Vertical). Peak Expiratory Flow and Physiological Responses was monitored and showed significant improvement in Sitting with Back Rest Vertical position followed by Long sitting and Three Quarter Sitting position than in Supine position P-value comes out to be significant for PEFR and Physiological Responses.
However there were no significant improvement in Heart Rate and Respiratory Rate in different Sitting positions as
compared to Mean Blood Pressure and Oxygen Saturation.
Conclusion: Body Positions has a significant effect on PEFR and Physiological Responses in Post Operative Cardiac Surgery patients. However the Heart Rate and Respiratory Rate does not show any significant change with the Body Positions.
