![]() Resulting in an increased ECV and thus salt accumulation. Overhydration refers to a clinical condition with an abnormal increase in total body water.Plasma osmolality is normally maintained constantīy the antidiuretic hormone feedback system. Plasma-osmolality is given in Osmol per kg of water. Osmolality is a measure of the osmotic active particles in one kg of water.Oedema refers to a clinical condition with an abnormal accumulation of tissue fluid.To a clinical condition with plasma- below 135 mM. Hypernatraemia refers to a clinical condition with plasma- above 145 mM.Hypokalaemia refers to a clinical condition with plasma- below 3.5 mM.Hyperkalaemia refers to a clinical condition with plasma- above 5 mM (mmol/l of plasma).Interstitial fluid (ISF) is the tissue fluidīetween the cells in the extravascular space. Remaining water (14-16 kg) with most of the water in tissue fluid (ISF) andĪbout 3 kg of water in plasma. Volume (ECV) refers to the interstitial and the plasma volume. This volume normally contains 26-28 litre (l) out of the Volume (ICV) refers to the volume of fluid Dextrans are polysaccharides of high molecular weight.Dehydration is a clinical condition with an abnormal reduction of one or more of the majorįluid compartments (ie, total body water with shrinkage of blood volume or.Concentration: The concentration of a solute is the amount of solute in a given fluid volume.Measure physiological fluid compartments and the body content of ions. To apply and use the above concepts in problem solving and in case histories.Ĭonservation of matter states that mass or energy can neither be created norĭestroyed (the principle of mass balance).To explain disorders with increased or reduced extracellular fluid Influence of age, sex and weight on the size of the total body water and its Of fluid compartments by indicator dilution, the measurement of total body-K + and -Na + and ![]() To describe the osmotic pressure in the body fluids, the measurement Secretion, the ionic composition in blood plasma, the water content of fat-Īnd muscle- tissue and the daily water transfer across the gastro-intestinal Pathophysiology Equations Self-Assessment AnswersĬoncepts: Dehydration, hyponatraemia, intracellular fluid volume (ICV),Įxtracellular fluid volume (ECV), interstitial fluid (ISF), overhydration, oxidation water, radioactivity, specificĭaily water balance, the K +- and Na +-balance, sweat ![]() Study_ Objectives Principles Definitions Essentials ![]() New Human Physiology | Paulev-Zubieta 2nd Edition Chapter 24 : Body Fluids and Regulation ![]()
