“…60 Much of the initial enthusiasm for compression stockings was supported by physiological evidence from radiopharmaceutical clearance, [63][64][65] invasive electromagnetic flowmeters, 7 and early Doppler ultrasound, 66,67 that intermittent compression increased resting venous blood flow velocities. The method of action that is often quoted, and has been suggested for some time, 68 is that the stockings compress the veins and reduce their diameter. The velocity of a given amount of blood flowing through a vessel is dependent on its cross-sectional diameter, as previously stated; therefore, the stockings would be expected to increase the velocity in the vein.…”

“…It is well recognized that extra-dermal compression reduces the overall cross-sectional area of the lower limb and increases the linear velocity of blood Xow in the venous system (Ido et al 1995;Meyerowitz and Nelson 1964;Stanton et al 1949). This reduction leads to an improved mean linear blood Xow of 0.5 to 2.5 cm s ¡1 (Litter 1952).…”

Effects of different levels of compression during sub-maximal and high-intensity exercise on erythrocyte deformability

The aim of the study was to test the hypothesis whether different levels of sock compression (0, 10, 20, and 40 mmHg) affect erythrocyte deformability and metabolic parameters during sub-maximal and maximal running. Nine well-trained, male endurance athletes (age 22.2 ± 1.3 years, peak oxygen uptake 57.7 ± 4.5 mL min(-1) kg(-1)) carried out four periods of sub-maximal running at 70% of peak oxygen uptake for 30 min followed by a ramp test until exhaustion with and without compression socks that applied different levels of pressure. Erythrocyte deformability, blood lactate, heart rate and arterial partial pressure of oxygen (pO(2)) were monitored before and during all of these tests. Erythrocyte deformability, heart rate, pO(2) and lactate concentration were unaffected by compression, whereas exercise itself significantly increased erythrocyte deformability. However, the increasing effects of exercise were attenuated when high compression was applied. This first evaluation of the potential effects of increasing levels of compression on erythrocyte deformability and metabolic parameters during (sub-) maximal exercise, revealed no effects whatsoever.

“…20 We found marked increases in blood flow velocity in both superficial and deep veins following compression of the leg with pressures as low as 20 mm Hg. The ideal compression pressure was 20 mm Hg; higher pressures increasingly interfered with venous flow.…”

Abstract-This review covers a representative sampling of investigations in hemodynamics and hypertension performed by the author during the period from approximately 1945 to 1980. The hemodynamic studies included a description of changes associated with congestive heart failure and with acute myocardial infarction. These studies emphasized for the first time the importance of left ventricular afterload and of the mobilizable venous reservoir. Other hemodynamic studies included diverse subjects such as the first and only recordings of pulse waves in arteries as small as 200 ␥m in diameter, velocity differences between red blood cells and plasma, turbulent blood flow in the ascending aorta, increase in velocity of blood flow of leg veins under compression, rates of transcapillary flow of solutes in humans, and the first use of external arterial pulse wave recordings to assess vascular compliance. Pioneer studies in hypertension included the first use of an antihypertensive drug to treat malignant hypertension and the first report of the treatment of hypertension with a thiazide diuretic.
