Study Notes

Body Temperature Part 1

  • Body temperature is a vital sign, along with pulse, oxygen saturation, blood pressure, and pain.
  • Vital signs are used to assess a person's physiological status and monitor body functions.
  • Vital signs are measured to monitor bodily functions.
  • Body temperature is the balance of heat produced and lost by the body.
  • Body temperature is measured in degrees (Fahrenheit or Centigrade).
  • Normal body temperature range is 36°C - 37.4°C.

Kinds of Body Temperature

  • Core temperature: Temperature of deep tissues (thorax, abdominal cavity). It is relatively constant (around 37°C).
  • Surface temperature: Temperature of skin and subcutaneous tissues. It fluctuates based on the environment.

Measurement Sites and Temperatures

  • Oral: 98.6°F (37°C)
  • Rectal: 99.6°F (37.5°C)
  • Axillary: 97.6°F (36.4°C)

Factors Affecting Heat Production

  • Basal metabolic rate (BMR): The rate at which the body uses energy for essential functions (breathing). BMR decreases with age.
  • Muscle activity: Movement and shivering increases metabolic rate.
  • Hormones (epinephrine, norepinephrine, sympathetic stimulation): Immediately increase cellular metabolism.
  • Thyroxine output: Increased thyroxine increases cellular metabolism throughout the body.
  • Fever: Increases cellular metabolic rate, increasing body temperature.

When to Assess Vital Signs

  • On admission to a healthcare facility to establish a baseline.
  • When a patient's health status changes or reports symptoms like chest pain, feeling hot, or faint.
  • As per doctor/nurse orders.
  • Before and after surgery/invasive procedures.
  • Before and after procedures that could affect respiratory or cardiovascular systems.
  • Before and after interventions that could affect vital signs (e.g., ambulation after bed rest).
