Effect of Percussion and Postural Drainage Positions on Cardiovascular and Respiratory Parameters

Abstract

Background of the study: There are different drainage positions for different lobes of the lungs but most studies on the effect of postural drainage and percussion on cardiovascular and cardiorespiratory are old and also inconclusive. Aims: The primary aim of this study was to determine the effect of postural drainage positions and percussion in prone lying with foot of bed raised to 45cm and right side lying with 45 degree turn on to the face on cardiovascular and cardiorespiratory parameters such as systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (RR) and respiratory rate (RR). Method: Forty subjects (20 males and females each) participated in the study and they were randomly assigned to 4 groups with 10 participants in each group. The cardiovascular and cardiorespiratory parameters were measured at sitting (pre-positioning), mid and postpositioning after 15 minutes. The data was analysed using descriptive and inferential statistic. Results: The results showed that percussion significantly decreased the systolic blood pressure (F = 3.15; P < 0.05) while the respiratory rate was increased significantly (F= 5.40; p < 0.05) when the subjects were in prone lying position. The result also showed that the systolic blood pressure and the respiratory rate increased significantly (F=I.26; p < 0.05) and (F=7.18; p
