Thermoregulation and Body Temperature

These flashcards cover essential vocabulary and concepts related to thermoregulation and body temperature, based on the lecture notes.

Thermoregulation

The process of maintaining the core body temperature at a nearly constant value.

Normothermia

The normal body temperature, which ranges between 36.5° C and 37.2° C.

Hypothermia

A body temperature below 36.2° C.

Hyperthermia

A body temperature above 37.6 ° C.

Fever

Elevation in body temperature due to a change in the hypothetical set point.

Body Temperature Measurement Sites

Common sites include oral, rectal, axillary, tympanic membrane, and temporal artery.

Compensatory Mechanisms of Hypothermia

Includes shivering and vasoconstriction to preserve body heat.

Malignant Hyperthermia

An inherited muscle disorder and acute life-threatening complication related to certain anesthetic drugs.

Hyperthermia Symptoms

Symptoms may include headache, nausea, skin flushed, dehydration, hypotension, tachycardia, and cardiovascular collapse.

Cooling Interventions for Hyperthermia

Include removing excess clothing, providing cool packs, and hydrating with cool fluids.

Heat Exhaustion

A condition marked by heavy sweating, muscle cramps, and dizziness, which can progress to heat stroke.

Heat Stroke

A severe condition characterized by confusion, dizziness, and potentially unconsciousness due to extreme body temperature.

Factors Affecting Body Temperature

Age, exercise, hormone levels, circadian rhythm, stress, and environmental conditions.

Interventions for Hypothermia

Include removing the person from cold, and providing external and internal warming measures.

Cooling Strategies in Hyperthermia

Should be performed cautiously to ensure effective heat loss without leading to complications.

Assessment Indicators of Hyperthermia

Symptoms including tachycardia, confusion, hot dry skin, and rapid breathing.
