25 lip 2023 · 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. The exact amount is unmeasurable but is estimated to be between 40 to 800mL/day in the average adult without comorbidities. [2]
What is 'insensible' water loss? This term refers to water loss due to: Transepidermal diffusion: water that passes through the skin and is lost by evaporation, and; Evaporative water loss from the respiratory tract; It is termed insensible as we are not aware of it.
Fluid balance charts must be completed for the following patients unless a decision has been made otherwise by a medical/surgical team, senior registered nurse or outreach: Acute illness o Sepsis o Bowel obstruction o Acute pancreatitis (or acute on chronic) o Liver failure o Malnutrition o Cardiac failure o Acute Kidney Injury (AKI)
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.)

Respiratory water loss averages 250–350mL/d in sedentary adults; however, physical activity can increase losses to about 600mL/d (19,25). Insensible water loss, which includes sweat loss, can vary with environmental conditions (i.e. wind speed, humidity, and sun exposure), activity level, body composition, degree of physical fitness, and ...
