The core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in; for example, in humans, the output (via respiration, perspiration, urination, defecation, and expectoration) must equal the input (via eating and drinking, or by parenteral intake).
Should intake be more than output?
The person is said to be in negative fluid balance if his output is greater than his intake. Conversely, a positive fluid balance occurs when intake is greater than output. If the difference is alarming, consult your doctor. Keep the chart to show to the doctor, and start a fresh one for the next 24-hours.
How do you accurately measure intake and output?
Ask the resident frequently if they have consumed any fluids between meals and add that amount to the I & O sheet. Place the I & O sheet in its designated place. Record oral intake immediately after meals, even before removing the tray. Record the output measurements immediately after they are measured.
