Vital Signs
Measurements for the body’s basic function
a.Body temperature (Temp)
b.Pulse/heart Rate (PR/HR)
c.Respiration Rate (RR)
d.Blood Pressure (BP)
- the balance between the heat production due to chemical activities by the body and heat lost from the body through radiation, conduction, convection and vaporization
Body Temperature
When to assess Vital Signs?
Upon admission to any healthcare agency
Based on agency institutional policy and procedures
Any time there is changes in the patient’s condition
Before and after surgical or invasive diagnostic procedure
Before and after activity that may increase risk
Before and after administering medications that affect cardiovascular ore respiratory functioning
-the temperature of deep tissues of the body (ex: cranium, thorax, abdominal cavity)
true core temperature can only be measured by invasive means
CORE TEMPERATURE
What is the normal body temperature?
normal body temp : 36.2 to 37.2c
the temperature of the skin, the subcutaneous tissue and fat
rises and falls in response to environmental changes
average oral temp: 36.7 – 37c

The period initiated by the first faint clear taping sound. These sound gradually become more intense.
Phase 1: Korotkoff’s sounds
The period during which the sounds have a swishing quality.
Phase 2: Korotkoff’s sounds
The period during which the sounds are crisper and more intense.
Phase 3: Korotkoff’s sounds
The period , during which the sounds become muffled and have a soft, blowing quality.
Phase 4: Korotkoff’s sounds
The period where the muffled, blowing sound disappear.
Phase 5: Korotkoff’s sounds
Pulse Pressure
the numeric difference between the systolic and diastolic blood pressure
For example, if the resting blood pressure is 120/80 millimeters of mercury (mm Hg), the pulse pressure is 40.
A pulse pressure within 40 is the normal and healthy pulse pressure .
A pulse pressure greater than 40 mm Hg is abnormal.
A high pulse pressure may be a strong predictor of heart problems (valve regurgitation), especially for older adults.
A pulse pressure lower than 40 may mean a patient have poor heart function.
Equipment for assessing blood pressure
Stethoscope and sphygmomanometer.
Electronic or digital devices.
