BLOOD PRESSURE
Blood Pressure is a measure of the blood’s pressure in the circulatory
system, which changes constantly during the course of the cardiac
cycle. Blood pressure readings report two values. The higher reading
(systolic pressure) shows the highest pressure in the arteries
occurring when the heart contracts. The lower reading (diastolic
pressure) shows the lowest pressure in the arteries, which occurs
right before the heart contracts. Blood pressure readings are written
with the highest value rst, then the lowest value. Readings of 120/80
are considered to be normal, with high blood pressure being dened
as a systolic pressure which is 140mmHg or more at rest and a
diastolic pressure which is 90mmHg or more at rest. Only a patient’s
physician is qualied to determine whether the readings obtained are
normal for that person.
Measuring blood pressure: Have the patient, while relaxed and in a
sitting position, extend the arm from which the blood pressure will be
taken to the front or laterally with the palm of the hand up.
Attach the cuff and diaphragm: Place the cuff approximately one inch
above the bend of the elbow against the skin of the upper arm with
the artery marker placed on top of the brachial artery. Never place
the cuff over clothing. Wrap the cuff around the arm and secure the
cuff with the “touch and hold” strap (If the cuff has a metal D-shaped
ring, pull the free end of the cuff through the D-ring and close the cuff
with the “touch and hold” strap). The cuff should be snug, but not too
tight. If one or two ngers can t between the cuff and the arm, the
cuff is properly secured. Place the diaphragm of the stethoscope over
the brachial artery inferior to the cuff.
