Blood Pressure Defined
• Blood Pressure is the force that
blood puts on the arterial walls as it
goes through the body.
• Readings are usually written as 2
numbers. The top number is called
SYSTOLIC BP. The bottom number is
called DIASTOLIC BP.
• BP is measured in millimeters of
mercury (mmHg).

Blood Pressure Defined
Example:
Systolic/Diastolic
120/80 mmHg
5
Blood Pressure Defined
• Systolic pressure: pressure when the
heart is contracting. It is specifically
the maximum arterial pressure
during contraction of the left
ventricle, of the heart.
• Diastolic pressure: the minimum
arterial pressure during dilatation of
the ventricles of the heart, when the
ventricles fill with blood.

Pertinent Anatomy
The Circulatory System:
• Moves blood throughout the body. It
is composed of the heart, arteries,
capillaries, and veins.
• Transports oxygenated blood from
the lungs and heart throughout the
body via the ARTERIES.
• Blood that has been depleted of
oxygen by the body is then returned
to the lungs and heart via the VEINS.

THE 5 POINTS OF PALPATION
• Carotid: on the neck
• Brachial: under the arm
• Radial : on the wrist
• Femoral: in the groin
• Pedal: on the foot

Baseline Knowledge
Heart Rate
Pulse: rate at which your heart beats
each minute (bpm).
Rhythm: frequency and strength of the
heartbeat.
How to check a pulse: Palpate a major
artery with your index and middle
fingers with light pressure. Count
how many times you feel a beat over
30 seconds and multiply by 2.
13
Baseline Knowledge
Heart Rate
Attain a Heart Rate:
• Palpate a major artery with your
index and middle fingers with light
pressure.
• Count how many times you feel a
beat over 30 seconds and multiply by
2.
Example:
HR: 77

Baseline Knowledge
Oxygen Saturation
• Is a measure of how much oxygen
the blood is carrying as a percentage
of the maximum it could carry.
• It is commonly annotated as SpO2%
Example:
SpO2: 98%

Baseline Knowledge
Blood Pressure in Adults
• Blood pressure rates can vary widely
• Ask questions such as physical
activity level and medications/
supplements taken.
Example
BP: 120/80

Instruments Orientation
Sphygmomanometer:
• blood pressure meter can be manual
or automatic
• composed of an inflatable cuff to
restrict blood flow, and a mercury or
mechanical manometer to measure
the pressure

Instruments Orientation
Stethoscope:
• is an acoustic device for auscultation
• usually consists of two-sided chest
piece (bell for low frequencies and
diaphragm for higher frequencies)
and a hollow tube used to transmit
sound.
24
Procedure Steps: Instruments
25
Procedure Steps
Position the Patient
• There are three positions for taking
BP: supine, seated, standing.
• In seated position, the patient's arm
should be flexed.
• The flexed elbow should be at the
level of the heart.
26
Procedure Steps
Position the Patient: Seated
27
Procedure Steps
• To begin, use a properly sized blood
pressure cuff. The length of the cuff's
bladder should be at least equal to
80% of the circumference of the
upper arm.
• Wrap the cuff around the upper arm
with the cuff's lower edge one inch
above the antecubital fossa.
28
Procedure Steps
• Lightly press the stethoscope's bell
over the brachial artery just below
the cuff's edge.
• Rapidly inflate the cuff to 180mmHg.
Release air from the cuff at a
moderate rate (3mm/sec).
• Listen with the stethoscope and
simultaneously observe the
sphygmomanometer.
29
Procedure Steps
• The first knocking sound (Korotkoff)
is the patient's SYSTOLIC pressure.
• When the knocking sound
disappears, that is the DIASTOLIC
pressure.
• Document your findings!!!

Practical Exercise
• Pulse/ Heart Rate (HR)
• Respirations (RR)
• Blood Pressure (BP)
