Development of an apparatus to measure plasma colloid osmotic pressure mounted on the extracorporeal hemodialysis circuit.
We newly developed an apparatus to measure colloid osmotic pressure (COP) of blood plasma continuously by hemodialysis (HD) or extracorporeal ultrafiltration method (ECUM) without any invasive procedure or blood sampling. The COP value measured by this apparatus highly correlated with the COP value calculated from the concentration of total protein of blood plasma (TP) sampled simultaneously (y = 21.182 + 0.96256x, r2 = 0.911). Measurement of the COP with this apparatus seems to be reliable.
