Shems Flashcards
Vital signs or cardinal signs are
Body temp, pulse, respiration, blood pressure
Types of body temp
Core and surface temp
Temp of the deep tissue of body
Core temp
Core temp is measured by
Oral and rectal temp
Temp of the skin, subcutaneous tissue and fat
Surface temp
Surface temp is measured by
Axillary temp
The heat regulating center in surface temp is found in the
Hypothalamus
Bodily heat is primarily produced by
Metabolisms
Increase cellular metabolic rate
Muscle activity
Characterized by increased body temp
Hyperthyroidism
Increase cellular metabolisms
Epinephrine, norepinephrine, sympathetic stimulation
Increase temp of body cells
Fever
Increases the rate of cellular metabolisms
Fever
Transfer of heat from the surface of one object to another without contact
Radiation
Transfer of heat from one surface to another with contact
Conduction
Requires temp difference between the two surfaces
Conduction
Dissipation of heat by air currents
Convection
Continuous vaporization of moisture from the skin, oral
Mucus, respiratory tract
Evaporation
Factors affecting temperature
Age
Diurnal variations
Exercise
Hormones
Body temp above normal range(hyperthermia, or fever)
Pyrexia
Very high fever, 41°C(105.8°F) and above
Hyperpyrexia
Subnormal core body temperature
Hypothermia
The temp fluctuates between periods of fever and periods of normal/subnormal temp
Intermittent fever
The temp fluctuates within a wide range over the 24 hour period but remains above be normal range
Remittent fever
