Blood Gases Response to Different Body Positions in Patients with Chronic Obstructive Pulmonary Disease in Intensive Care Unit

Abstract

This study was designed to evaluate the effectiveness of postural changes (supine, side lying and prone), on arterial blood gases and hemodynamic variables in patients with chronic obstructive pulmonary diseases(COPD), with hypothesis that there were no stastical significance differences in arterial blood gases, and hemodynamic variables. Fifty four patients of both sexes (eight female and forty six male) were participated in this study. They were recruited from intensive care unit (ICU) of Waide El-Nile Hospital. Their age ranged from (55-70) years, with mean values of (65±5.35 year). All patients complained from dyspnea, cough, and expectoration, with forced expiratory volume in one second (FEV 1) less than 80% of predicated value. The blood gases {Pa02, PaC02, Sa02, HC03, and pH), and hemodynamic variables (HR, RR, and MAP), had been measured at baseline supine position and two hours after assuming side lying and prone position respectively, and . analyzed through using acid-base analyzer device and (ECG) monitor respectively. The results of this study revealed that there was no effect of postural changes on (HR, RR, and MAP).
