Influence of posture on pulmonary gas exchange and heart rate in chronic obstructive lung disease

J Schaanning et al. Scand J Respir Dis. 1976.

Abstract

Sixteen subjects with chronic obstructive lung disease were studied in supine and sitting position. VT, VE, VD and VD/VT were definitely higher in the sitting position (p less than 0.001). PaCO2 was slightly lower in the sitting position, whereas Pa¿O2 was the same in both positions. P(A-a)O2 was essentially the same in both positions, but the estimated QS/QT was definitely lower in the sitting position. In patients with low FEV1.0 the heart rate showed a tendency towards higher values in the sitting position.
