Measurement of body fluids. Warren spence 4 adam moscovitch 5 rüdiger hardeland 6 daniel p. Rapid mixing of tritiated water throughout all compartments occurs during a 3 to 4 hour equilibration period. The different types of body fluids include. This fluid volume tends to be very stable because the amount of water in living cells is closely regulated. This is estimated by measuring the volume of distribution of isotopes of water. For example a 180 pound.
We can compute the concentration of any solution using the following equation. Brown 8 and s. Measurement of fluid volumes in the different body fluid compartmentsthe indicator dilution principle. 222 total body water. To calculate how much water you should drink daily to maintain a healthy amount of water in your body divide your weight in pounds by 2 and drink that amount in ounces. 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.
Cardinali 7 gregory m. It is a thick fluid containing 55 blood 90 water and 8 proteins. The volume of a fluid compartment in the body can be measured by placing an indicator substance in the compartment allowing it to disperse evenly through out the compartments fluid and then analyzing the extent to which the substance becomes diluted. The main components of blood include. Electrolyte concentrations of body fluids are usually expressed in milliequivalents per liter meql a measure of the number of electrical charges in one liter of solution. Standards protocols and procedures eduardo alves de almeida 1 paolo di mascio 2 tatsuo harumi 3 d.
Measurement of melatonin in body fluids. Tritium oxide tho is used because it is a weak beta emitter making it easy to measure in a liquid scintillation counter. Meql ion concentration mgl divided by the atomic weight of the ion mgmmol x the. Another way to measure body water is through dilution and equilibration using mass spectrometry which measures the abundance of water in breath samples from an individual. One way to get an uncertain estimate is by calculation based on body weight and urine output.
