Fluid and electrolyte balance depends upon the ingestion and excretion of fluids as well as electrolytes. Water is main source of fluids. Water is provided by drinking or ingested in solid food. Sodium, potassium and magnesium are main electrolytes in body. Body fluid volume and electrolyte concentration are normally maintained within very narrow limits despite wide [ ].   One of the main roles of electrolytes and their homeostasis is the distribution of fluids throughout the human body. Colloidosmotic and hydrostatic pressures are the main forces influencing the fluid distribution between intravascular and interstitial spaces, whereas changes in intra or extracellular osmolality are in general followed by water.

Electrolytes, particularly sodium, help the body maintain normal fluid levels in the fluid compartments because the amount of fluid a compartment contains depends on the amount (concentration) of electrolytes in the electrolyte concentration is high, fluid moves into that compartment (a process called osmosis). Likewise, if the electrolyte concentration is low, fluid moves out of that. Electrolytes allow nerves to fire and muscles, including the heart, to contract; regulate acid-base balance; support hormone and tissue production; and maintain proper fluid balance within cells, interstitial fluid, and blood plasma. There are many electrolytes in the human body, but the most important are: Sodium; Potassium; Chloride.

In terms of body functioning, six electrolytes are most important: sodium, potassium, chloride, bicarbonate, calcium, and phosphate. Roles of Electrolytes These six ions aid in nerve excitability, endocrine secretion, membrane permeability, buffering body fluids, and controlling the movement of fluids between compartments.   GIFTASUP recommend that to maintain fluid and electrolyte balance adult patients should receive sodium 50– mmol/day, potassium 40–80 mmol/day in – litres of water. 4 Further replacement of electrolytes should only be given to restore a deficit or replace ongoing loss. Enteral water is useful in those patients with hypernatraemia.

Overview of Fluid and Electrolyte Balance Water is made up of 2 hydrogen atoms and 1 oxygen atom (Figure “The Water Molecule”). A human body is made up of mostly water.

An adult consists of about 37 to 42 liters of water, or about eighty pounds.

Prelude to Fluid, Electrolyte, and Acid-Base Balance Water is the most ubiquitous substance in the chemical reactions of life. The interactions of various aqueous solutions—solutions in which water is the solvent—are continuously monitored and adjusted by a large suite of interconnected feedback systems in your body.

patient’s fluid balance, avoiding fluid and electrolyte derangements, and optimizing pharmacotherapy. For example, total body water (TBW) and hydration status affect the pharmacokinetics of medica-tions by altering the volume of distribution, and for select medica-tions, electrolytes may influencedrug therapy or vice versa (Meyers ).

Electrolytes Important for Fluid Balance Cells are about 75 percent water and blood plasma is about 95 percent water.

Why then, does the water not flow from blood plasma to cells. The force of water also known as hydrostatic pressure maintains the volumes of water between fluid compartments against the force of all dissolved substances. A conceptual model and a mathematical method are presented for computing the physiological fluid and electrolyte distribution for selected body compartments of an average, young, kilogram human male.

The mathematical procedure simulates the physiological subsystems by incorporating all the known chemical reactions and electrochemical relations which seem necessary to establish the fluid and.

The ICF makes up about 60 percent of the total water in the human body, and in an average-size adult male, the ICF accounts for about 25 liters (seven gallons) of fluid (Figure ). This fluid volume tends to be very stable, because the amount of water in living cells is closely regulated.

Fluids and electrolytes play a vital role in homeostasis within the body by regulating various bodily functions including cardiac, neuro, oxygen delivery and acid-base balance and much more. Electrolytes are the engine behind cellular function and maintain voltages across cellular membranes.

Mechanism. Several principles control the distribution of water between the various fluid compartments. To understand the different principles, it is essential to realize the following: ingestion and excretion of water and electrolytes are under tight regulation as to maintain consistent total body water (TBW) and total body osmolarity (TBO).

Intracellular Fluid. The ICF lies within cells and is the principal component of the cytosol/cytoplasm. The ICF makes up about 60 percent of the total water in the human body, and in an average-size adult male, the ICF accounts for about 25 liters (seven gallons) of fluid (Figure ).This fluid volume tends to be very stable, because the amount of water in living cells is closely regulated.

Principles of Body Water Distribution Body control systems regulate ingestion and excretion: constant total body water - constant total body osmolarity Homeostatic mechanisms respond to changes in ECF.

No receptors directly monitor fluid or electrolyte balance. - Respond to changes in plasma volume or osmotic concentrations Cells are the basic unit of structure and function of life.

A balance between fluids and electrolytes is necessary if cells are to survive and function normally. According to "Nursing Standard," approximately 60 percent of the human body is water, and body water contains electrolytes.

It is the kidneys' job to control fluid and electrolytes. Humans demonstrate a remarkable ability to regulate daily body water and electrolyte balance so long as food and fluid are readily available.

The imposition of exercise and environmental stress. For an understanding of fluid and electrolyte balance, it is important to appreciate the distribution of total body fluid.

In essence, the fluid that is present in the body is divided into two different compartments - the extracellular compartment and the intracellular compartment (Krogh, ).unchanged distribution of substances in different body fluids.

Fluid balance refers to the proper levels of water and electrolytes being in the various body compartments according to their needs. Osmotic pressure (created by the dissolved electrolytes in body fluids) and hydrostatic pressure (created by the.Medical books Fluid and Electrolyte Balance.

Completely revised and updated, this Fifth Edition provides in-depth discussion of fluid and electrolyte balance and imbalance with a strong focus on understanding pathophysiology. Further, it outlines basic concepts and gives an overview of the nursing considerations for fluid and electrolyte.
