The total oncotic pressure of an average capillary is about 28 mmHg with albumin contributing approximately 22 mmHg of this oncotic pressure, despite only representing 50% of all protein in blood plasma at 35-50 g/L. [6] [7] Because blood proteins cannot escape through capillary endothelium, oncotic pressure of capillary beds tends to draw ...
is the interstitial hydrostatic pressure; is the plasma protein oncotic pressure; is the interstitial oncotic pressure; is the hydraulic conductivity of the membrane (SI units of m 2 ·s·kg −1, equivalent to m·s −1 ·mmHg −1)
Approximate Normal Value [11] [12] P c: Capillary hydrostatic pressure P c = 0.2 × Arterial Pressure + Venous Pressure 1.2 25mmHg (arteriolar end) 10mmHg (venous end) P i: Tissue interstitial pressure Determined by the compliance of tissue Compliance = volume/Δ pressure Varies by location ≅ −6 mmHg Π c: Capillary oncotic pressure
Typical values for the viscosity of normal human plasma at 37 °C is 1.4 mN·s/m 2. [3] The viscosity of normal plasma varies with temperature in the same way as does that of its solvent water [4];a 3°C change in temperature in the physiological range (36.5°C to 39.5°C)reduces plasma viscosity by about 10%.

"Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
A high gradient (> 1.1 g/dL, >11 g/L) indicates the ascites is due to portal hypertension, either liver related or non-liver related, with approximately 97% accuracy. [2] This is due to increased hydrostatic pressure within the blood vessels of the hepatic portal system , which in turn forces water into the peritoneal cavity but leaves proteins ...
Anatomy and physiology is different in infants and children than adults and vary with age, which produces normal ranges for electrocardiograms. [26] Capillary refill is used across the lifespan as a cardiovascular assessment parameter because it is a non-invasive, quick test to help determine blood flow to the tissues.
Hypoalbuminemia (or hypoalbuminaemia) is a medical sign in which the level of albumin in the blood is low. [1] This can be due to decreased production in the liver, increased loss in the gastrointestinal tract or kidneys, increased use in the body, or abnormal distribution between body compartments.
