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.

22 paź 2023 · Sensible losses pertain to conventional forms of excretion, such as urination and defecation, whereas insensible losses pertain to less obvious fluid expenditure, including sweating and respiratory evaporation.
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.)
insensible water loss (IWL) is greatest in the smallest and least mature infants due to high surface area to body mass ratio and to immature, water-permeable skin.
10 sty 2020 · Insensible Water Loss Insensible water loss represents about a third of the total daily maintenance fluid requirements. This loss occurs by evaporation through the skin and the lungs. A febrile child loses an additional 10–15% per one degree centigrade rise in temperature above 38° centigrade through this means (Greenbaum 2010b).
