Vital Signs: Acceptable ranges for Adults
|
Temperature Ranges: 36C to 38C (96.8 to 100.4 F) |
|
Factors affecting body temperature
|
Age - Temp. regulation is unstable in children until they hit puberty. Normal temp. range gradually drops as individuals approach older adulthood. Avg. oral temp. for older adults is approx. 36C (96.8F). Older adults are more sensitive to temp. changes due to poor vasomotor control, reduced amounts of subQ tissue, reduced sweat gland activity, and reduced metabolism. |
|
Pyrexia |
Fever. Occurs b/c heat-loss mechanisms are unable to keep pace w/ excess heat production, resulting in an abnormal rise in body temp. Fever is usually not harmful if it stays below 39C. or 102.2F
|
|
Patterns of Fever |
Sustained - A constant body temp. continuously above 38C (100.4F) that has little fluctuation |
|
Classification of Hypothermia
|
Mild : 34-36C (93.2F-96.8F)
Moderate : 30-34C (86.0-93.2F) Severe : < 30C (<86.0F) |
|
Fahrenheit to Celsius
Celsius to Fahrenheit |
C = (F-32) x 5/9
F = (9/5 x C) +32 |
|
Dangers of Fever p. 507
|
Cellular Hypoxia
a. Myocardial Hypoxia = produces angina b. Cerebral Hypoxia = produces confusion and may include O2 therapy. Dehydration (water loss through increased respiration and diaphoresis) |
|
Hyperthermia and Malignant Hyperthermia |
Hyperthermia - elevated body temp. related to body's inability to promote heat loss or reduce heat production. Results from an overload of the body's thermoregulatory mechanisms.
Any disease or trauma to the hypothalamus impairs heat-loss mechanisms. Malignant Hyperthermia - hereditary condition of uncontrolled heat production, occurring when susceptible persons receive certain anesthetic drugs. |
|
Heatstroke
|
heat depresses hypothalamic fxn. caused by prolonged exposure to sun or high environmental temp. |
|
Heat exhaustion
|
occurs when profuse diaphoresis results in excess water and electrolyte loss. |
