The chemicals in the body which are responsible for regulating physiologic functions are termed the electrolytes. These electrolytes when dissolved in water, become positively and negatively charged producing the electric current needed by the body for performing several functions.
Body fluids Physiology illustrates that water is the most abundant constituent in the body which is divided into two Body Fluid Compartments. One is intracellular fluid and the other is extracellular fluid. Plasma and interstitial fluid are the sub-classification of extracellular fluid. To provide an understandable explanation of the composition of body fluids, a graphical representation is given.
Information is also provided about water homeostasis and sodium homeostasis. The role of aquaporin along with other water channels is also discussed while talking about the pathophysiology of fluid and electrolyte balance.
The discussion continues on an abnormality associated with electrolyte imbalance known as hypovolemia. In this disorder, two conditions arise i.e. loss of sodium from extracellular space which is referred to as volume depletion and the intracellular water loss which is referred to as dehydration. Its renal and extrarenal causes are discussed comprehensively.
Furthermore, hypovolemic Shock is made understandable which is characterized by severe Blood loss and other complications such as peripheral hypoperfusion, peripheral cyanosis, peripheral vasoconstriction, hypotension. It is also discussed that how compensated Shock gets worse and leads to the decompensated Shock.
After carrying out its diagnostic evaluation, the focus is shifted towards the treatment. Treatment of mild hypovolemia, severe hypovolemia, and bicarbonate loss and metabolic acidosis is discussed.
