Vital Signs are measurements reflecting the patient’s
physical well-being and condition.
Often VS are the first indicator that something
adverse is going on with the patient.
Routinely measured Vital Signs :
BP-blood pressure
P-pulse
R-respirations
T-temperature
Sp02-Pulse oximetry (ox)
Sometimes Pain is included
When ARE
vital signs
taken?
At each MD visit
When MD orders
Change in pt condition
Pt fall/incident
Monitor pt’s response to
a new med
*Always Consider:
The VS results as well as patient’s clinical appearance and
history. **Recheck if results do not match appearance.
This means look at the patient NOT just the numbers!
Temperature
Terms to Know
Febrile: fever
Afebrile: absence of fever
Pyrexia: fever (>100.4 F)
Hyperpyrexia: abnormally high fever (Emergent >104 F)
Fever is the body’s natural defense against infection
The most common sign of inflammation or infection is fever.
The patient may also exhibit other S/S of infection such as
chills, anorexia, malaise/fatigue, body aches, tachycardia
FUO: fever of unknown origin (can be the pt’s dx)
Fever lasting >3 weeks in an adult; >1 week in children
Temperature
Normal body temperature is 98.6ºF or 37ºC
Our internal body temperature is regulated by a part of our
brain called the hypothalamus.
Are variations normal?
Variations are caused by:
Individual differences
Age- elderly/infants have harder time regulating body temp
Time of day-temp increases in late evening; weather
Hot/cold liquids, smoking, chewing gum
Menstrual cycle- can increase body temperature

Ear: tympanic (aural)
Rectum: rectal
Armpit: axillary
Forehead: Temporal
Oral
Temperature
(O)
Measured in the mouth
Most common, comfortable and convenient
method
May be inaccurate if patient has had
anything to eat/drink, chewed gum, or
smoked
Wait 10-15 minutes
Place a probe cover on the thermometer
Then place the probe in the heat pocket
under tongue (to the side of the frenulum
lingua)
Normal Average Oral Temp 97.6-99.6 F
Measured in the mouth
Most common, comfortable and convenient
method
May be inaccurate if patient has had
anything to eat/drink, chewed gum, or
smoked
Wait 10-15 minutes
Place a probe cover on the thermometer
Then place the probe in the heat pocket
under tongue (to the side of the frenulum
lingua)
Normal Average Oral Temp 97.6-99.6 F
Axillary
Temperature
(A)
Temperature measured under the armpit
Least accurate reading because measures external
temperature
Record an A by the reading
Provide privacy
Center probe in armpit
Measure the temperature
Rectal
Temperature
(R)
Measured in the rectum
Most accurate because it is an internal temperature
Use red rectal thermometer
Record R by reading
Adult Procedure: Have pt lay on their side, lubricate
thermometer, insert thermometer no more than 1 inch
into the rectum
Children: insert probe no more than 5/8 inch
Infants: insert probe no more than ½ inch
Tympanic
(Aural)
Temperature
Temperature measured in the ear canal
May be inaccurate if the patient has impacted cerumen
(ear wax)
Contraindicated in patients with ear pain or ear
infection such as otitis externa
Adults-gently pull pinna (outside of ear) up and out
Children gently pull pinna down and back
Impacted
Cerumen
and
Tympanic
(Aural)
Temperature
Tympanic temperatures are obtained by measuring the
temperature of the ear drum (tympanic membrane)
Compare the above ear canals…can you see how a
tympanic temperature will be inaccurate if the ear canal is
occluded (covered) in cerumen (wax)
Temporal
Temperature
Temperature measured across the forehead
Obtains a measurement of temperature inside the
temporal artery
Preferred by pediatricians due to:
Inaccuracies in technique while obtaining tympanic
temperatures
*Pediatric Note:
Febrile seizures can occur in young children with
high fevers. Antipyretic drugs such as Tylenol
should be administered to prevent these dangerous
spikes in temperature.
Clinical
Situations-Te
mperature
At the bottom of your notes:
Answer the clinical situations in the boxes.
Review the “How to Read a Glass Thermometer” and
provide the correct reading on your notes
Large lines equal 1 degree
Represent a whole number- 96°, 97°, 98°, 99°, 100°, etc.
Small lines equal 0.2 degrees
Ex. 99.2°, 99.4°, 99.6°
For example, this reading would be recorded as 99.4 F
Rhythmic expansion and contraction of the heart causes a
palpable beating of the arteries throughout body
Normal Pulse
Rates
(per minute)
NHA Pulse Rates:
Before birth/birth
120-160/min
1-3 years old
80-150/min
3-6 years old 70-110/min
6-12 years
60-110/min
Over 12/Adults
60-100/min
**Follow your specific facility policies regarding normal ranges
When
taking a
pulse,
note
the…
Rate: # of pulse beats per minute (bpm)
Rhythm: regular or irregular (arrhythmia)
Strength/Force: volume of the pulse
3+ Bounding- very strong
2+ Normal pulse
1+Thready- weak, difficult to feel
Bradycardia: HR< 60/min
Tachycardia: HR> 100/min
**Always report a pulse under 60bpm or over 100 bpm
Pulse Points
Check
for adult
CPR
For injuries, check pulses distal to the injury for circulation.
A doppler unit (ultrasound) may need to be used to detect pulse.

Palpating
a Radial Pulse
Support pt’s arm
Use second and third finger of your dominant hand to
palpate (feel) the radial pulse
Your fingers are in a line with the patient’s thumb
Never use your own thumb*
Don’t press too hard- you will stop the flow of blood
and not feel the pulse
Count for a full minute
Look at the position of the second hand on your watch.
Start counting the pulse beats that you feel until the
second hand comes back to the same number on the
clock.
Record the rate, rhythm, and force.
Auscultating
an Apical
Pulse
Apical pulse is a measurement of the heartbeats at the
apex of the heart (just under the left breast)
Apical pulse commonly measured in:
Infants and children
Adults with irregular heartbeats
Uncover the patient’s chest
Auscultate (listen) with stethoscope for a full minute
Press down firmly with the stethoscope
Count the number of beats and note the rhythm
Compare these chest x-rays. Which one depicts dextrocardia?
Which pulse procedure technique will be affected?
How would you modify your technique to get an accurate pulse?
Clinical
Situations
Pulse
Answer the clinical situations in the boxes on your study
guide. Then write the correct answers on your
whiteboard.
Homework
Take a radial pulse on three “patients”. Write the
readings obtained on looseleaf and have the person sign
next to the reading.
If you do not have 3 different people at home, you may
take three separate readings on the same person at 3
different times. Have the “patient” sign.

Observing
Respirations
Respiration: involuntary process of inhaling and exhaling
The purpose of respiration:
To exchange oxygen and carbon dioxide between the
atmosphere, blood, and body cells
Medulla oblongata- location of respiratory center
In the brain between brainstem and top of spine
When blood CO2 levels increase, cells are starved for O2
The medulla oblongata responds by sending a stimulus to
respiratory muscle (diaphragm and intercostal muscles)
and breathing begins involuntarily

Abnormal
Breath Sound
Recognition
The provider assesses breath sounds with a stethoscope
Abnormal breath sounds may be audible without a stethoscope and
can indicate severe respiratory disease
Wheezing
Whistling sound
Asthma
Rales
Small clicking, bubbling, or rattling sounds (crackles)
Pneumonia, fluid in air sacs (pulmonary edema)
Rhonchi
Large airway sounds (snoring or gurgling-mucous moving)
COPD, Chronic bronchitis, Pneumonia
*Be alert for the any of the following:
Cyanosis, vertigo, angina, numbness in fingers and toes
Pulse
Oximetry
(SpO2)
Using a sensor to measure the saturation of oxygen in the blood
Nail polish/artificial nails provide inaccurate results (remove prior)
Check capillary refill in fingers to select the best site
Alternate sites- earlobe, bridge of nose, toe
Normal SpO2: 95% or greater
A reading < 95 % indicates hypoxemia:
Low oxygen in the blood
Oxygen therapy may be ordered and initiated
*According to NHA, SpO2 readings <90% must be reported to the
provider—follow facility protocols for reporting!
Assessing and
Documenting
Pain
Pain is often assessed with vital signs and is subjective
Observe for grimacing, clutching areas of the body
Assessing and Documenting Pain
Assess pain scale 1-10 (10 is worst)
For children, use Wong-Baker Faces Scale
Ask about location, onset, duration, other characteristics
Also, any relieving or aggravating factors
Measuring
Blood Pressure
Blood
Pressure
Basics
The force of blood exerted on the inner walls of arteries, veins, &
heart chambers heart as blood flows through them
BP variations: age, internal conditions, external influences
Accurate BP impacts patient treatment
Normal adult range: Less than 120/80 mmHg
Equipment needed:
Stethoscope and aneroid sphygmomanometer
Or electronic sphygmomanometer
Measurements read at 2 points:
Systolic- pressure measured as heart contracts
Diastolic- pressure measured as heart relaxes
Recorded as a fraction
Blood
Pressure
Procedure
Special
Considerations
Wait 15 min. after strenuous activity
Anxiety/stress elevates BP- help pt relax
Do not take BP in same arm as:
An injury or implant
The same side as a mastectomy
An IV or AV shunt (dialysis fistula)
-Use proper size cuff
The bladder inside the cuff should encircle 80-100% of the arm
Legs uncrossed, feet on floor, arm positioned at heart level
- Apply cuff to upper arm just above brachial pulse point
-Use palpatory method to determine approximate BP
Palpate the radial pulse
Inflate cuff until you no longer feel radial pulse
Note the pressure at this point
Deflate cuff
Rest arm 30-60 seconds
-Determine auscultated blood pressure
Inflate cuff 30 mmHg above palpatory result (usually 150-180 mmHg)
Listen with stethoscope over brachial artery as you release air
Note the blood pressure reading (see next slide)
Recording the
Blood
Pressure
Korotkoff
Sounds
Korotkoff Sounds
Phase 1- first tapping sound (systolic)
Phase 2- softer, swishing sounds
Phase 3- tapping sounds resume
Phase 4- sounds become muffled
Phase 5- sounds disappear (diastolic)
**When you begin the procedure by inflating cuff, you
should hear NO SOUND initially. The first sound is your
top number & the last sound is the bottom number.
