In order to elucidate the circulatory and respiratory effects of a newly developed abdominal compression binder 25 healthy, normal weight subjects were studied. In supine position the central haemodynamics were measured and estimated with a Finapress device. Lower extremity venous haemodynamics were measured in supine position with venous occlusion plethysmography. In an upright-seated position arterial oxygen saturation was measured by a pulseoxymeter for 1 h before spirometry was performed with a turbine flow measurement device. All the tests were performed in a randomized order with or without the abdominal compression binder. The results show that the compression binder significantly increases the venous volume in the lower extremities as showed by a reduction in the venous capacitance in the lower extremities and a reduction in the stroke volume and cardiac output, while it does not influence the pulmonary volumes.
It is concluded that the applied abdominal binder significantly affects peripheral and central haemodynamics. It should therefore be used with caution when in the supine position for longer periods, as the pooling of blood it induces in the lower extremities may have implications for the risk of deep venous thrombosis formation.
