(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
what pulse is located in the periphery of the body
Peripheral Pulse
what pulse is located at the apex of the heart
Apical Pulse (Central Pulse)
pulse rate is expressed in
expressed in beats/minute(BPM)
Factors Affecting Pulse Rate
- Age
- Sex
- Autonomic Nervous system activity
- Parasympathetic (decrease) -Sympathetic (increase) - Exercise
- Fever
- Heat
- Stress
- Medication
BPM of infant
100-160 BPM
normal BPM
60-100 BPM
pulse site on the side of the neck
Carotid
pulse is taken at temporal bone
Temporal
apex of the heart
Apical
inner aspects of the biceps muscle
Brachial
on the thumb site
Radial
along the inguinal ligament
Femoral
behind the knee
Popiliteal
on the medial surface of the ankle
Posterior Tibial
dorsum of foot
Pedal (Dorsal Pedis)
pulse is commonly assessed by
Palpation or Auscultation
assess the pulse for:
- Rate
- Rhythm
- Volume
- Elasticity of the arterial
normal pulse rate
60-100 BPM
Adult PR > 100 BPM
Tachycardia
Adult PR < 60 BPM
Bradycardia
pattern and interval between beats , random
and irregular beats (dysrythymia)
Pulse Rhythm
the force of blood with each beat
Pulse Volume
act of breathing and includes intake of oxygen of carbon-dioxide
RESPIRATORY RATE
refers to movement of air in
and out of the lung
Ventilation
very deep, rapid respiration
Hyperventilation
very shallow respiration
Hypoventilation
Factors Affecting Respiration
- Age
- Medication
- Stress
- Exercise
- Altitude
- Gender
- Fever
how to assess respiratory rate
by watching the movement of the chest or abdomen or how many times the chest rises * Rate * rhythm * depth
RR of healthy adult
15-20/min
normal breathing
Eupnea
slow respiration
Bradypnea
fast breathing
Tachypnea
temporary cessation of breathing
Apnea
difficulty of breathing
Dyspnea
RR for new born
30-80/min
RR for early childhood
20-40/min
RR for late childhood
15-25/min
RR for adult male
14-18/min
RR for adult female
16-20/min
force exerted by the blood against the walls of the arteries in which it
is flowing
BLOOD PRESSURE
BP is expressed in terms of
millimeters of mercury (mm of Hg)
2 types of BP
Systolic pressure
Diastolic pressure
the maximum of the pressure against the wall of
the vessel
Systolic pressure
the minimum pressure of the blood against the
walls of the vessels
Diastolic pressure
-BP is measured by using an instrument called
Bp cuff
(sphygmomanometer) and Stethoscope
Normal Value of Bp
120/80mmHg
Factors Affecting Blood Pressure
- Fever
- Stress
- Arteriosclerosis
- exposure to cold
- Obesity
- Hemorrhage
- Hematocrit
- External Ear
Sites for Measuring Blood Pressure
- Upper arm
- Thigh around popliteal artery
- Fore-arm
- Leg using posterior tibial or dorsal pedis
purpose of assessing BP
to obtain base line measure of arterial blood pressure
- determine the clients homodynamic status
- identify and monitor changes in blood pressure
high Bp
Hypertension
less than the normal range
Hypotension
