Changes in the lung functions of an individual during his normal sleeping body and arm position compared to supine position

Abstract

In normal people there are considerable inequalities of the ventilation and perfusion in the lung which can be further changed by position. Thus different V/Q mismatches will ultimately have an impact on arterial oxygenation. This study was designed to detect whether the lung functions are changed by adopting the patient's normal sleeping posture and the arm position during sleep.
