discussion:
see other than the lines and tubes, urine, the following things should be notes:
1. Insensible fluid loss is the amount of body fluid lost daily that is not easily measured, from the respiratory system, skin, and water in the excreted stool.
2. The exact amount is unmeasurable but is estimated to be between 40 to 800mL/day in the average adult without comorbidities.
for all practical purposes ,
fever and mechanical ventilation causes the insensible fluid loss.
per degree rise in fever causes 2.5 ml body fluid per kilogram body weight per day (approx.); so average 70 kg person will loss 175-200 ml .
and on mechanical ventilation around 700-1000 ml fluid loss.

How to estimate insensible fluid loss in ICU ?discussion:

and on mechanical ventilation around 700-1000 ml fluid loss.
one more reference;
- Insensible loss: 600–900 mL (lungs and skin). (With fever, each degree above 98.6°F [37°C] adds 2.5 mL/kg/d to insensible losses; insensible losses are decreased if a patient is undergoing mechanical ventilation; free water gain can occur from humidified ventilation.)
