Factors Affecting Body Temperature01:28

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may  include:
Decreased Body Temperature01:29

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
Body Temperature01:25

Body Temperature

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...
Body Temperature01:07

Body Temperature

Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C (97–99°F), remaining relatively stable...
Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's forehead...

Summary

Hypothermia is uncommon in intubated patients during northern aeromedical transport. Core body temperature is generally maintained, even without active warming, suggesting current practices are adequate for brief transports.

Area of Science:

  • Emergency Medicine
  • Transport Medicine
  • Critical Care

Background:

  • Aeromedical transport in northern regions poses a risk of hypothermia.
  • Assessing hypothermia risk in severely ill or injured patients during helicopter transport is crucial.

Purpose of the Study:

  • To determine the incidence of significant hypothermia in intubated patients during rotary wing aeromedical transport.
  • To evaluate core body temperature changes during helicopter transport in northern areas.

Main Methods:

  • Prospective cohort study of intubated patients over 16 years old transported by rotary wing aircraft.
  • Core temperature measured at 10-minute intervals using esophageal thermometers during transport.

Main Results:

  • Severe hypothermia occurred in 1-2% of patients; 28-39% had mild hypothermia pre-transport.
  • Core temperatures did not significantly decrease during transport.
  • Warming techniques were documented in only 38% of cases.

Conclusions:

  • Significant hypothermia is uncommon during brief (<225 km) aeromedical transports.
  • Body temperature is generally well-maintained with passive measures.
  • Aggressive core temperature monitoring is not recommended for this patient population during transport.
