COLLOID OSMOTIC-PRESSURE OF THE BLOOD - PHYSIOLOGY, MEASURING TECHNIQUE AND PREANALYTIC INFLUENCING FACTORS

Since the fundamental work of Starling the central of colloidosmotic pressure for maintaining volume homoeostasis and for transcapillary fluid exchange has been well known. To treat an intravasal volume deficit colloidal plasma substitution solutions are able to secure a sufficient colloid osmotic pressure. The last one can be measured by oncometry. Therefore an individual therapy is possible. This review describes the physiologic function, measurement techniques and important influencing parameters and disturbing factors which may be taken into consideration when colloid osmotic pressure is determined.
