Labtron V223 Mobile Adjustable Aneroid Sphygmomanometer 6
Proper deation rate is vital for an accurate reading. The
recommended deation rate is 2-3mmHg per second, or a
drop of one to two marks on the pressure gauge with each
heartbeat. Do not keep the cuff inflated any longer than
necessary. As the cuff begins to deate, listen carefully
with the stethoscope. Note the reading on the gauge as
soon as a faint, rhythmic tapping or thumping sound is
heard. The rst sound is the systolic pressure reading.
Always check with your health care provider to ensure
readings are performed correctly.
Diastolic blood pressure reading: Allow the pressure to
continue dropping at the same deation rate. Note the
reading on the gauge when the last audible thumping,
swishing, or blowing sound is heard; this is the diastolic
blood pressure reading. After a few seconds have passed
and no audible thumping, swishing, or blowing sounds
are heard, deate the cuff using the air release valve
completely. Remove the cuff and stethoscope from the
arm.
Record the systolic and diastolic readings. Repeat the
measurement two or more times to ensure accuracy. Only
a patient’s physician is qualied to analyze blood pressure.
