Vitals Flashcards
What are the 4 vital signs
- Temp
- Pulse
- Respiratory Rate
- Blood Pressure
What is considered the 5th vital sign
Pain
When should vitals be measured
- On admission to hospital
- Beginning of shift (for inpatient)
- Before / during / after surgery
- Before / after certain meds
How often should vitals be taken in the hospital
Every 4 - 6 hours
Core temp is how many degrees above skin temp
1 - 2
Define Thermoregulation
The balance of heat production and heat loss
What 3 ways is body heat produced?
- Metabolism
- Skeletal muscle movement
- No -shivering Thermogenesis
What is BMR (basal metabolic rate)
The amount of energy required to maintain the body at rest
What condition increases the BMR?
Hyperthyroidism
Excess thyroxine
What condition decreased the BMR?
Hypothyroidism
Low thyroxine
What are 4 modes of heat transfer
- Radiation
- Convection
- Conduction
- Evaporation
Describe radiation
Electromagnetic waves emit heat from skin
What percentage of body heat is lost by radiation
50%
Describe Convection and give an example
- Transfer of heat through air/water
- Warm bath or blowing fan
Describe Conduction
Heat transfer from warm surface to cooler surface
Describe evaporation
Water converted to vapor
How much body heat is lost to evaporation
15 - 20%
Normal Blood Pressure
<120 /<80
Normal pulse
Average pulse
60 - 100bpm
80bpm
What is the normal temperature range?
Average temp?
- 8 - 100.4
98. 6
Axillary temp
Oral temp
Rectal temp
97 - 97.6
98 - 98.6
99 - 99.6
Most accurate type of measurement for Core Temp
PA Catheter
Normal Respiratory Rate
12 - 20 breaths/min
Tachypnea
> 20 breaths/minute
