Which type of fluid loss is an example of insensible loss?

Respiratory loss
Respiratory loss is an insensible loss. This is water that is used to humidify inspired air and is then breathed out as water vapor.

How do you calculate pediatric fluid loss?

A plan for rehydration should be developed after the initial fluid resuscitation. The first step is to calculate the fluid deficit. This is determined by multiplying the percentage dehydration times the patient’s weight (e.g. 10% dehydration in a 10 kg child: 10% of 10 Kg = 1 kg = 1 liter).

### What causes insensible water loss?

The major route of intake of water is by ingestion of fluids and food. Food contains water, and additional water is produced during oxidation of carbohydrates. The major routes of water loss are urine, feces, sweat and insensible water loss by evaporation from the respiratory tract and diffusion through the skin [1].

### How does insensible water loss occur?

Insensible perspiration is the loss of water through the skin which does not occur as perceivable sweat. Insensible perspiration takes place at an almost constant rate and reflects evaporative loss from the epithelial cells of the skin. Unlike in sweating, the fluid lost is pure water, i.e. no solutes are lost.

What is an insensible loss?

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.

When do you give D5?

Dextrose 5% in water is used to treat low blood sugar (hypoglycemia), insulin shock, or dehydration (fluid loss). Dextrose 5% in water is also given for nutritional support to patients who are unable to eat because of illness, injury, or other medical condition.

#### How do you calculate fluid loss?

This is calculated by dividing the difference between the pre-illness and illness weights by the pre-illness weight, then multiplying by 100 (Table 5). For example, a 10-kg patient who has lost 1 kg is 10% dehydrated. Every 1 kg of weight lost is equivalent to 1 L of fluid loss.
