Remember the 60-40-20 rule which indicates that 60% of body weight is water, 40 % is ICF and 20% is ECF. ECF is composed of ¼ th plasma and ¾ th interstitial fluid. Plasma constitutes 55% of blood volume. The interstitial fluid resembles plasma except that plasma proteins and blood cells are absent.
How do you calculate body fluid compartment?
To calculate the interstitial (fluid not in the cells and not in the blood) fluid volume, subtract the plasma volume from the extracellular volume. To calculate the intracellular fluid volume subtract the extracellular fluid volume from the total fluid volume.
How is ICF measured?
Intracellular fluid volume – Cannot be measured directly but can be calculated by subtracting ECFV by TBW, as the latter two variables are measurable. Interstitial fluid volume – Cannot be measured directly but can be calculated by subtracting PV by ECFV, as the latter two variables are measurable.

The normal range for adult women varies between 45% and 60%. For men, the ideal body water percentage fluctuates between 50% and 65% of the total body. In babies, that number is much higher. The norm is considered to be between 75% and 78%, dropping to 65% by one year of age.
How many liters of total body water does an 80kg man have?
In an 80-kg man, the ECF volume averages 20 liters; thus, 1.2% of 20,000 ml equals 240 ml. A satiated ECF osmolality of 285 mosmol/kg would require ingestion and assimilation of 0.285 x 240 ml = 68.4 mosmol to induce drinking. This is equivalent to (6.245 g of NaCl/liter x 68.4 mosmol)/285 mosmol/kg = 1.5 g of NaCl.

The distribution of fluid throughout the body can be broken down into two general categories: intracellular fluid and extracellular fluid. Intracellular fluid is approximately 40% of the total body weight.
What is 3rd space fluid loss?Third-spacing occurs when too much fluid moves from the intravascular space (blood vessels) into the interstitial or “third” space-the nonfunctional area between cells. This can cause potentially serious problems such as edema, reduced cardiac output, and hypotension.

WHO ICF 2001?
ICF is the WHO framework for measuring health and disability at both individual and population levels. ICF was officially endorsed by all 191 WHO Member States in the Fifty-fourth World Health Assembly on 22 May 2001(resolution WHA 54.21) as the international standard to describe and measure health and disability.
What is the ratio of ICF to ECF?
The ratio of ICF to ECF is 55:45. The functional ECF is more important when considering the effects of acute fluid interventions and the ratio of ICF to functional ECF is 55:27.5 (which is 2:1).
What are ICF codes?
The International Classification of Functioning, Disability and Health (ICF) is a framework for describing and organising information on functioning and disability. It provides a standard language and a conceptual basis for the definition and measurement of health and disability.
Is water weight bad?
Overall, water weight is normal and drinking a lot of water won’t lead to health problems or problems on your bathroom scale. In fact, being dehydrated can cause your body to store water to compensate, which can lead to more water weight.
What should my body fat be?
The amount of essential fat differs between men and women, and is typically around 2-5% in men, and 10-13% in women. The healthy range of body fat for men is typically defined as 8-19%, while the healthy range for women is 21-33%.
Why does body water increase with weight loss?
When eating returns to normal and the body starts to store protein and carbohydrates again instead of breaking them down, water weight increases. For real weight loss, you must gradually reduce calorie intake to a healthy level, with a balance of carbohydrates, healthy fats and proteins.
Do you lose fat after water weight?
It’s not uncommon to lose upward of 3 to 4 pounds of fat over the course of 3 to 4 weeks without even knowing it due to increased water retention. The fat loss only becomes visible when the excess fluid is flushed out of the body, creating the illusion of extreme fat loss over very short periods.
What does water weight look like?
If you press on your skin and an indentation stays there for a couple of seconds, that’s a sign you have water weight. One way to check if you’re retaining water is to press on swollen skin. If there’s an indention that stays for a little while, that’s a sign that you could be retaining water.

How much water should a 50kg person drink?
As a general rule, you can use this simple calculation. Water (in litres) to drink a day = Your Weight (in Kg) multiplied by 0.033. For example, if you are 60kg, you should drink about 2 litres of water every single day. At 90kg, you’ll around about 3 litres of water.
Is 4 Litres of water a day too much?
Drinking enough water offers health benefits, however, drinking too much water, such as 3-4 liters of water, in a short period leads to water intoxication. For proper metabolism, a normal human body requires about two liters of water.

- Your total is how many ounces of water you should drink each day.
What age group has the highest percentage of body water?

Water, the principal constituent of fluids in animals, including humans, is taken into the body orally in foods and liquids and, to a lesser extent, is produced by the oxidation of food during metabolism. The average adult human takes in between 2,100 and 3,400 ml (2.2 and 3.6 quarts) of water per day.
