(LAB) VITAL SIGNS Flashcards
reflect the body’s physiologic status and provide
information critical to evaluating homeostatic balance.
Vital Signs
4 main Vital signs
- Body Temperature
- Pulse Rate
- Respiratory Rate
- Blood Pressure
It is the HOTNESS or COLDNESS of the body
TEMPERATURE
Normal Body temperature using oral
37 degrees C or 98.6 degreesF
TWO KINDS of Body Temperature
Core Temperature
Surface Temperature
it is the temperature of internal organs and it remain constant most
of the time (37:C); with the range of 36.5 - 37.5 :C)
Core Temperature
- is the temperature of the deep tissues of the body
- measure with thermometer
Core Temperature
- it is the temperature of the skin, subcutaneous and fat cells.
Ranges between 20 - 40:C
Surface Temperature
it doesn’t indicate internal physiology
Surface Temperature
Normal Body Temperature is
37 degreesC or 98.6 degreesF
range of normal body temperature
36-38 deg c (96.8-100 deg F)
high temperature
Fever
Hypothermia
low temperature
body temperature above the normal
ranges
Pyrexia(fever)
a very high fever leads to death
Hyperpyrexia
body temperature between 34:c - 35:c that leads to
death
Hypothermia
periods of fever and periods of normal temp
Intermittent fever
- a wide range of temperature fluctuation occurs
over the 24 hours period
Remittent fever
short febrile periods
Relapsing fever
fluctuates minimally but always remains above
normal
Constant Fever
Factors Affecting Body Temperature
- Age
- Exercise
- Hormones
- Stress
- Environment
by putting thermometer under the tongue (3to5 mins)
(most common site for temp measurement)
Oral Temperature
safe and non invasive, it is recommended for infants and children (5to10mins)
Axillary
reflects the core body temperature and readily accessible and permits
rapid temp readings (1to2seconds)
Tympanic or Ear
inserting thermometer into the rectum about 1/2 inch (3to5mins)
Rectal
a special thermometer can quickly measure the temperature of the skin
Skin
normal temp range for oral
98.6F / 37.0C
normal temp range for Tympanic
99.6F / 37.6C
normal temp range for Rectal
99.6F / 37.6C
normal temp range for Axillary
97.6F / 36.6C
is a wave of blood created by contraction of left ventricle
pulse
reflects the heart beat
PULSE RATE
are two important
factors influencing pulse rate
stroke volume and compliance of arterial wall
