Abstract In an attempt to determine the P/V relation in human limb veins noninvasively and to assess its accuracy, simultaneous measurements of electrical admittance, water displacement plethysmography, venous occlusive cuff pressure and intravenous pressure were carried out in 36 healthy subjects (29 males and 7 females; aged 20–46). The cuff pressure was controlled with a cuff inflator. There was a close and linear correlation between these two plethysmograms and between the direct intravenous and cuff pressure. These results suggest that the P/V relationship in human limb veins can be determined noninvasively by the measurement of electrical admittance change caused by the venous occlusive cuff pressure change controlled by the inflator.
