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).
