Exclusion criteria
• Blood pressure is not measured if a participant has• Both arms amputated• Cast on both arms• Open wounds/sores on both arms• Rash on both arms• Malformation on both arms preventing
to place the cuff• Lymph node malfunction in both arms
Setting up the measurement site
• Room should be• Quiet• Comfortable temperature• No disturbance
• Measurement device placement• Measurer has clear view• Participant cannot see the
results• If mercury
sphygmomanometer is used, mercury column at the eye level of the measurer
Instruction to the participants
• Before blood pressure measurement, participants should abstain from • Eating• Drinking (except water)• Smoking• Heavy exercise• Taking drugs that affect blood pressure
for one hour before the measurement
Position of the subject
Feet resting on the floor, not crossed
Back supported
Position of the arm
Right arm, resting on the desk
Palm is facing up
In line with heart
Removal of clothingSleeves rolled up, not constrictive
Remove constrictive sleeves
Selection of the cuff
• The bladder of the cuff should be• Width: At least 40%
of the arm circumference
• Length: At least 80% of the arm circumference
Measurement process
• Participant is asked to sit still for 5 minutes
• Participant is asked not to talk during the measurement
• Arm circumference is measured and cuff selected
Cuff is placed 2-3 cm above antecubital fossa
By automated device
• After the cuff has been placed, follow the instructions of the used device
• Measure blood pressure 3 times, one minutes between measurements
By mercury sphygmomanometer (1)
• The radial pulse is palpatated and the pulse rate is counted for 60 seconds
• Record 60 sec pulse count and whether or not the pulse was regular
By mercury sphygmomanometer (2)• Determine the
peak inflation level• The brachial pulse
is located and the bell of the stethoscope is placed
Inside the bicep muscle tendon
Not touching the cuff, rubber or clothing
By mercury sphygmomanometer (3)• Inflate the cuff rapidly
to the peak inflation level
• Deflate at the rate of 2 mmHg/second
• Systolic blood pressure: Korotkoff Phase I
• Diastolic blood pressure: Korotkoff Phase IV
• Record measurement to the nearest 2 mmHg
• Wait 1 minute• Repeat measurement
two more times
