Vital Signs 2.0 Flashcards
measures of various physiological status, in order to assess the most basic body functions.
Vital signs
are useful in detecting or monitoring medical problems.

VITAL SIGNS
Are measurements of the body’s most basic functions:
- Body temperature (Temp).
- Pulse / heart rate.
- Respiration.
- 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( evaporation) .
Body temperature
Types of body temperature
CORE temperature - The temperature of deep tissues of the body
SURFACE temperature - the temperature of the skin, the subcutaneous tissue and fat. It, by contrast rises and falls in response to the environmental changes.
Factors Affecting Body’s heat production
Basal metabolic rate ( BMR)
Muscle activity
Thyroxin output
Epinephrine and Sympathetic stimulation
Age
Gender
Diurnal variation
Exercise
Alterations in Body Temperature
A body temperature above the usual range is called _____, _____, or ( in lay terms) fever.
Pyrexia, hyperthermia, or fever
A very high temperature, e.g. 41Co (105 oF) is called _____
hyperpyrexia
Common types of fevers
Intermittent Fever
Remittent Fever
Relapsing Fever
Constant Fever
convert from Fahrenheit to Celsius
For example: C= ( 98.6- 32) × 5/9
deduct 32 from the Fahrenheit, and then multiply by 5/9
convert from Celsius to Fahrenheit
F = ( 37 × 9/5) + 32
multiply the Celsius reading by the fraction 9/5 and then add 32 .
the numeric difference between the systolic and diastolic blood pressure
Pulse pressure
A pulse pressure within 40 is the normal and healthy pulse pressure .
The normal BP is 120/ 80 mmHg.
the force required by the heart to pump blood from the ventricles of the heart into the arteries. It is measured in systolic and diastolic pressure.
Blood pressure
a complete cycle of an inspiration composes one respiration .
