DEFINITIONS OF INTAKE AND OUTPUT
a. Intake. Intake is any measurable fluid that goes into the patient's body.
Intake includes fluids (such as water, soup, and fruit juice) and "solids" composed
primarily of liquids (such as ice cream and gelatin) that are taken by mouth (orally),
fluids that are introduced by IV, and fluids that are introduced by irrigation (through a
b. Output. Output is any measurable fluid that comes from the body. Water
given off in the form of perspiration and water vapor (exhaled breath) is also output, but
it is not recorded on the DD Form 792, since it cannot be accurately measured. (An
adult usually looses about 500 milliliters (ml) a day through perspiration and moisture
exhaled in breathing.) The major forms of output recorded on the worksheet are urine,
drainage, vomitus (matter vomited), and stools (fecal discharge from the bowels).
Intake and output are measured in milliliters (ml) or cubic centimeters (cc).
Since 1 milliliter is equal to 1 cubic centimeter, the terms millimeters and
cubic centimeters will be interchangeable for the purpose of this subcourse.
Conversion equivalents are found in Table 1-1 and in the "Intake Equivalents"
section of DD Form 792.
1-10. COMPLETING THE TWENTY-FOUR HOUR PATIENT INTAKE AND OUTPUT
a. Patient's Identification Section. Enter the information in the lower left

Line 1. Patient's name (last, first, middle initial); rank or grade or
(b) Line 2. Hospital register number; family member prefix code and
sponsor's social security number.
Line 3. Patient's sex (M or F); patient's age.
