The effect of body positioning upon maximal oxygenation of patients with unilateral lung pathology . A quasi-experimental , repeated-measures cross-over design study on the effect of body position on oxygenation ( SaO2 ) blood pressure , respiration and pulse in patients with unilateral lung pathology was conducted . Previous research strongly suggests that positioning with the healthy ( unaffected ) lung in the dependent lateral ( down ) position is related to improved oxygenation , but knowledge about whether this effect is maintained over time is lacking . The purpose of this investigation was to determine : ( 1 ) Is positioning with the unaffected lung in the dependent lateral position related to increased arterial blood saturation levels and decreased blood pressure , pulse and respiration ? ( 2 ) What is the relationship between the dependent variables -- oxygenation saturation levels , blood pressure , pulse and respiration -- and the independent variables -- body position and time in the position ? Thirty-nine patients with unilateral lung pathology were positioned on their sides with the unaffected lung down , on their sides with the affected lung down , and also in semi-Fowler 's position . Arterial ( SaO2 ) blood saturation and vital signs were measured at baseline 0 , 15 and 30 minutes . There was no statistically significant relationship between oxygenation level or systolic blood pressure . Diastolic blood pressure , respiration and pulse did vary significantly with position .
