WEEK 5 – VITAL SIGNS
ECU NORMAL VS VALUES
• Temperature – 36 – 37.5
• Pulse – 60-100 per min
• Resp – 12-20 per min
• BP – 100-140/<80
• Oxygen saturation/SPO2 = >94% pr 95-100%
• Pain – scale of 0-10, 10 being worst
Indications for assessing vital signs
• On admission
• Before/after surgical/diagnostic procedure
• Before/during/after medication administration
• Change in health status
• Before/after nursing certain interventions
• Patient reports symptoms of physical distress
• Routine schedule
• Concern about patients condition
• RN – accountable for analyzing and interpreting vital signs
Vital signs showing deterioration
• Respiratory rate
• Pulse
• BP
BODY TEMPERATURE
• Difference between amount of heat produced by body and amount of heat
lost to environment (temp = heat produced – heat lost)
• Normal body temp = 36 – 37.5 degrees Celsius
• Thermoregulation balances heat produced and heat lost (feedback
mechanism)
- Hyperthermia - elevated temperature, inability to promote heat loss
or reduce heat production (death at 41-45 degrees celsius)
- Hypothermia – decreased body temp, inability to produce heat (death
without intervention <30 degrees Celsius)
• Factors effecting temperature
- Age
- Exercise
- Stress
- Environment
- Pyrexia/fever
• Sites of measurement – oral, axilla (armpit), tympanic, rectum
