NOTE: Most people have difficulty grasping the
significance of the volume of fluid lost during a 24-
hour period of time during respiration. In order to
illustrate this point, the next question will ask you to
estimate the volume of fluid lost during a day in
respiration. Do not attempt to find this figure in the
above paragraph.
FRAME 39
QUESTION: Estimate the volume of fluid lost in a
24-hour period of time in respiration.
__________ milliliters
Solution to Frame 39

milliliters of urine in 24-hours. One liter of urine will
contain approximately 75 mEq of sodium, 40 mEq
of potassium, and 80 mEq of chloride.
FRAME 41
Adding these normal fluid losses:
PERSPIRATION
650 ml/day
FECES
100 ml/day
RESPIRATION
450 ml/day
URINATION
1,300 ml/day
2,500 ml/day
Approximately 2,500 milliliters of fluid are normally
lost during a 24-hour period of time by the average
individual.
