Vital Signs Flashcards
6 Vital Signs
Temperature, Pulse, Blood Pressure, Respiratory Rate, Oxygen Saturation, Pain
When to measure vital signs?
On admission, per physician order, any change in patient condition, before/ after procedures, during blood transfusion, after meds or interventions
Normal Temp Ranges
96.8-100.4
Oral/ tympanic/temporal
97.6-99.6
Rectal Temp
98.6-100.4
Axilla Temp
96.6-98.6
Normal Pulse
60-100 beats per minute
Normal Respirations
12-20 breaths per minute
Normal Blood Pressure
Less than 120/80
Blood pressure- Pre- Hypertensive
120-139
80-89
Blood pressure- Hypertensive
> 140
90
Blood pressure- Hypotensive
Systolic <90 and symptomatic
Hypothalamus
Thermostat of the body
Anterior Hypothalamus (front)
Controls heat loss, sweating
Posterior Hypothalamus
Controls best production, vasoconstriction (creates shivering)
Basal metabolic rate
Metabolism creates heat
Heat Loss- Radiation
Transfer of heat from surface of one object to surface of another without direct contact
Heat Loss- Conduction
Transfer of heat from one object to another with direct contact
Heat loss- Convection
Transfer of heat away by air movement
Heat loss- Evaporation
Transfer of heat energy when a liquid is changed to gas
Heat loss- Diaphoresis
Visible perspiration
Factors affect Body Temp
Age, exercise, hormonal levels, circadian rhythm, environment, temperature alterations
Fever (pyrexia)
Usually not Hangul if below 102.2°
Defense mechanism
Febrile
Fever present
Afebrile
No fever
FUO
Fever of unknown origin
