Oncotic pressure ndash principle of measurement
the sample of blood serum plasma
semipermeable membrane(permeability to Mr 20000 )
isotonic saline solution
pressure sensor
The permeability of saline solution into sample through the membrane is given by osmosis The sensor measures the pressure decrease of saline solution (due to decrease its volume bdquounderldquo membrane)
The oncotic pressure is a part of the osmotic pressure of plasma maintained by macromoleculs
48
The oncotic pressure= colloid osmotic pressure = bdquoCOPldquo
COP = 266 ndash 333 kPa (approximately 3 kPa)
COP = 133 ndash 266 kPa danger of edema pulmonum
COP lt 14 kPa no survive without iv administration of albumin
(80 COP of plasma ensures albumin)
49
oncotic pressure
hydrostatic pressure
Capillary ndash the movement of fluid between plasma and ISF
arterial end of capillary
hydrostatic pressure exceedsoncotic pressure filtration
of fluid into ISF
venous end of capillary
oncotic pressure exceedshydrostatic pressure reabsorption
of ISF back to the capillary
length of blood capillary
pressure
50
The oncotic pressure- normal concentrations of blood proteins
P-albumin = 35 ndash 50 g l-1
P-total protein = 62 ndash 82 g l-1
Compare grave swelling and ascites in serious hypoproteinemias of the kwashiorkor type
