A telemetric technique for studies of venous pressure in the human leg during different positions and activities.
The pressure in the saphenous vein of the lower leg was monitored by ordinary ECG telemetry equipment supplied with a pressure transducer, a chopper and an extra filter. In eight healthy volunteers venous pressure averaged 80 +/- 5 (SD) mmHg in the standing position and 21 +/- 10 (SD) mmHg during slow walking. When the subjects were occupied with laboratory work in upright position the mean venous pressure was 40-50 mmHg, similar to that obtained sitting at a desk: 48 +/- 5 (SD) mmHg.
