Closely reflects core temperature
Lower esophageal temperatures
Normal daily temperature variations
0.5 oC
Rectal Temperature
Generally 0.4 oC higher than oral temperature
How does menstruation affects temperature?
AM temperature lower in 2 weeks before ovulation then rises by ~0.6 oC with ovulation
Elevation of body temperature that exceeds the normal daily variation
Fever
An increase in the hypothalamic set point
Fever
In fever, body temperature rises by how many degrees?
1-2 oC
Fever of greater than 41.5 oC
Hyperpyrexia
Most commonly occurs in patients with CNS hemorrhages
Hyperpyrexia
Elevated temperature caused by abnormal hypothalamic function
Hypothalamic Fever
Setting of hypothalamic center is unchanged
Hyperthermia
Cause by exogenous heat exposure and endogenous heat production
Hyperthermia
Uncontrolled increase in body temperature that exceeds the body’s ability to lose heat
Hyperthermia
Temperature below 35 oC
Hypothermia
Commonly palpated to assess the pulse rate
Radial artery
Normal PR
60-100 beats per minute
Condition wherein pulse rate is less than the heart rate
Atrial Fibrillation
Normal respiratory rate
~20 breaths per minute
You should tell the patient that you are getting his/her RR. True/False
