“…Mercury-in-rubber strain gauges measure the change in volume of only a small segment of the limb. However, when the gauge is placed around the largest circumference of the calf, this method reliably measures limb blood flow [13]. Mercury-in-rubber straingauge plethysmographs are portable and much simpler to use than the other instruments.…”

Peripheral circulation in the newborn: Interaction of peripheral blood flow, blood pressure, blood volume, and blood viscosity

Peripheral blood flow and systolic blood pressure (strain-gauge plethysmograph), blood volume (Evans blue) and whole blood viscosity (cone-plate viscometer) have been measured in 66 premature and full-term infants 6 to 144h of age. Blood flow and blood volume were moderately decreased in the infants with respiratory distress. Highly significant (P less than 0.001) correlations were found between blood flow and blood volume (r = 0.77), blood pressure and blood volume (r = 0.50), peripheral resistance and blood volume (r = -0.44), blood flow and blood pressure (r = 0.50), blood flow and peripheral resistance (r = -0.67), peripheral resistance and blood viscosity (r = 0.45), and blood viscosity and haematocrit (r = 0.86). There was no correlation between peripheral blood flow and blood viscosity. However, at given blood volume, peripheral blood flow decreased with increasing blood viscosity. These results indicate that in newborn infants peripheral blood flow, blood pressure and peripheral resistance are influenced by blood volume, but also depend on blood viscosity.

“…Withinsubject reproducibility has been assessed by several groups, with a reported variation coefficient of between 11% and 15% [11][12]19]. Calf blood flow measured by SGP has been shown to correlate strongly with femoral blood flow measured by both Doppler ultrasound [11,20] and direct limb perfusion via cannulation of the femoral artery and vein [21]. It is considered to be a reliable and accurate measure of blood flow to the extremities.…”

Renal transplantation is the preferred method of renal replacement therapy, having been shown to increase life expectancy, improve quality of life and be more cost-effective compared to continued dialysis [1,2]. There has been a recent push to extend the benefits of transplantation to older patients with more comorbidities. Despite a perceived increased risk of complications, current literature indicates

“…Basal forearm blood flow (FBF) was measured with the participant seated upright, using Hokanson Plethysmography with a venous occlusion technique. Strain gauge plethysmography has been validated against machine flow and Doppler ultrasound . A voltage‐dependent silastic mercury strain gauge sized 2‐3 cm less than the right forearm circumference was attached to the forearm 5 cm distal from the cubital fossa and secured with tape.…”

Menopausal transition accelerates an age-associated decrease in vascular function and a decline in aerobic fitness. The purpose of this study was to examine the effect of 8 weeks of interval sprinting cycle ergometer exercise on arterial stiffness, basal forearm blood flow, and aerobic fitness of post-menopausal women. Sixty overweight post-menopausal women were randomized into either exercise (Ex, n = 30) or control (C, n = 30) groups. Ex participants completed 24 interval sprinting exercise (ISE) sessions over 8 weeks. Each 20-minute ISE session comprised of alternating 8 seconds sprints and 12 seconds of light pedaling. Arterial stiffness assessed through ankle-brachial pulse wave velocity (baPWV) and augmentation index (AIx), basal forearm blood flow (FBF) assessed using venous occlusion, and aerobic fitness were assessed before and after the intervention. baPWV was significantly decreased in the Ex group by 7.2%, P = .03, whereas AIx demonstrated a 10% decrease, P = .002.No changes were found in basal FBF. Aerobic fitness was significantly increased, P = .002, in the Ex group (14%) with no change occurring in the control group. ISE training, despite minimal exercise commitment time (8 hours over 8 weeks), significantly lowered the arterial stiffness and increased the aerobic fitness of postmenopausal women. These results suggest that ISE positively influences the negative change in arterial stiffness and aerobic fitness that typically accompanies menopause.
