Vital Signs
•
•
•
•
Are important indicators of health
Detect changes in normal body function
May signal life-threatening conditions
Provide information about responses to
treatment
Vital Signs
•
•
•
•
Temperature
Pulse
Respirations
Blood Pressure
Vital Signs Are Measured:
– Upon admission
– As often as required by the person’s condition
– Before & after surgery and other procedures
– After a fall or accident
– When prescribed drugs that affect the respiratory
or circulatory system
– When there are complaints of pain, dizziness,
shortness of breath, chest pain
– As stated on the care plan
When Measuring Vital Signs
• Usually taken with the person sitting or lying
• The person is at rest
• Always report:
– A change from a previous measurement
– Vital signs above or below the normal range
– If you are unable to measure the vital signs
Temperature
• Measurement of balance between heat lost
and produced by the body.
– Heat is produced by:
• Metabolism of food
• Muscle and gland activity
– Heat may be lost through:
• Perspiration, Respiration, Excretion
• Measured with the Fahrenheit (F)
or Celsius or Centigrade (C) scales

Illness
Infection
Exercise
Excitement
High temperatures in the
environment
• Temperature is usually
higher in the evening
Starvation or fasting
Sleep
Decreased muscle activity
Exposure to cold in the
environment
Temperature Sites
• Oral - by mouth – most common method
– May be affected by hot or cold food, smoking,
oxygen, chewing gum
– Wait 15 minutes or use alternate site
• Rectal - in the rectum -most accurate site
– Do not use if patient has rectal surgery or bleeding
• Axillary - under arm – less reliable site
– Used when other sites are inaccessible
– Do not use immediately after bathing
Temperature Sites
• Tympanic or aural - in the ear
– Measures in 1 to 3 seconds
• Temporal Artery – temporal artery on the
forehead
• Record route temperature was taken

( 97.6 - 99.6)
(98.6 - 100.6)
(96.6 - 98.6)
(98.6 - 100.6)
(98.6 - 100.6)
Hypothermia – temperature below normal
Hyperthermia – temperature above normal
Types of Thermometers
• Clinical (glass) thermometer no longer contain
mercury.
– Come in oral and rectal.
– Disposable covers are usually used.
• Electronic can be used for oral, rectal, or axillary and
use disposable probe covers.
• Tympanic placed in auditory canal and uses
disposable cover.
• Strips that contain special chemicals or dots
that change colors can also be used.
Pulse
• The pressure of blood pushing against the wall
of an artery as the heart beats and rests.
• Measured for one minute while noting:
– rate - beats per minute
– rhythm - regular or irregular
– volume - strength or intensity - described as
strong, weak, thready, bounding
Pulse Sites
Most Commonly Used:
•
•
•
•
•
Carotid – during CPR
Apical – use stethoscope
Brachial – for Blood Pressure
Radial - to count pulse
Femoral – assessment and
procedures
• Popliteal – assessment
• Dorsalis Pedis – assessment
Normal Ranges
Age
Birth to 1 year
2 years
6 years
10 years
12 years & older
Pulse per Minute
80-190
80-160
75-120
70-110
60-100
Bradycardia – Under 60 beats per minute
Tachycardia – Over 100 beats per minute
Factors that Affect Pulse
• Factors that  pulse
• Factors that  pulse

Exercise
Stimulant drugs
Excitement
Fever
Shock
Nervous tension
Sleep
Depressant drugs
Heart disease
Coma
Respirations
• Process of breathing air into (inhalation) and
out of (exhalation) the lungs.
• Oxygen enters the lungs during inhalation.
• Carbon dioxide leaves the lungs during exhalation.
• The chest rises during inhalation and falls during
exhalation.
• Normal rate 12-20 breaths per minute
Assessing Respiration
• Respirations is measured when the person is
at rest.
• Rate may change is patient is aware that it is
being counted.
• To prevent this, count respirations right after
taking a pulse.
• Keep your fingers or stethoscope over the pulse site.
• To count respirations, watch the chest
rise and fall.
Assessing Respiration
• Character and quality of respirations is also assessed:
–
–
–
–
–
Deep
Shallow
Labored or difficult
Noises – wheezing, stertorous (a heavy, snoring type of sound)
Moist or rattling sounds
• Dyspnea – difficult or labored breathing
• Apnea – absence of respirations
• Cheyne-Stokes – periods of dyspnea followed by periods of apnea;
often noted in the dying patient
• Rales – bubbling or noisy sounds caused by fluids or mucus in
the air passages
Blood Pressure
• Measure of the pressure blood exerts on the walls
of arteries
• Blood pressure is controlled by:
– The force of heart contractions
• weakened heart  drop in BP
– The amount of blood pumped with each heartbeat
• loss of blood  drop in BP
– How easily the blood flows through the
blood vessels
• Narrowing of vessels  increase in BP
• Dilatation of vessels  decrease in BP
Factors that Affect Blood Pressure
Factors that  blood
pressure
• Excitement, anxiety,
nervous tension
• Stimulant drugs
• Exercise and eating
Factors that  blood
pressure
• Rest or sleep
• Depressant drugs
• Shock
• Excessive loss of blood
Measuring BP
• A sphygmomanometer is used to measure BP
– Aneroid – has a round dial and needle
– Mercury – has a column of mercury
– Electronic – automated device
• BP is measured in millimeters (mm) of
mercury (Hg).
• The systolic pressure is recorded over the
diastolic pressure.
Normal Range of Blood Pressure
• Systolic: Pressure on the walls of arteries when the heart is
contracting.
Normal range – less than 120 mm Hg
• Diastolic: Constant pressure when heart is at rest
Normal range – less than 80 mm Hg
• Hypertension—BP that remains above a systolic
of 140 mm Hg or a diastolic of 90 mm Hg
• Hypotension—Systolic below 90 mm Hg and/or
a diastolic below60 mm Hg
Measuring Height and Weight
• Used to determine if patient is underweight or
overweight
• Height and weight charts are used as averages
• Weight greater or less than 20% considered normal
• BMI or Body Mass Index a statistical measure of
body weight based on a person's weight and height.
• BMI from 18.5 to 24.9 is considered normal
Measuring Height and Weight
General Guidelines:
•
•
•
•
•
•
•
•
Use the same scale every day
Make sure the scale is balanced before use
Weigh the patient at the same time each day
Remove jacket, robe, and shoes before weighing
OBSERVE SAFETY PRECAUTIONS!
Prevent injury from falls and the protruding height lever.
Some people are weight conscious.
Make only positive comments when weighing patients
Types of Scales
• Clinical scales contain a balance beam and
measuring rod
• Bed scales or Chair scales are used for patients
unable to stand
• Infant scales come in balanced, aneroid, or digital
– When weighing an infant…keep one hand slightly over but
not touching the infant
– A tape measure is used to measure infant height.
The 5 Early Warning Signs of Illness
1. Weakness – sudden onset TIA, pneumonia,
dehydration, CHF, infection, liver failure
2. A sudden change in greeting
– severe hearing loss, depression confusion
3. Nervousness or Agitation –
being emotionally off can signal physical illness
4. Loss of appetite
5. A resident complains
ABC’s of Observation
• Appearance
• Behavior – actions, conduct, pain
• Communication
Signs and Symptoms
• Signs
-- Objective data are seen, heard,
felt, smelled. You can see
urine, hear a cough, feel a pulse
and
smell a foul odor.
• Symptoms -- Subjective data are thing a
person tells you about that you
cannot observe through your
senses. Examples include
nausea, pain and dizziness.
