Purpose
Non-invasive recording of systolic and diastolic blood pressure
in humans. The device can be used for arm circumferences as
shown on the cuff.
Important
Protect your blood pressure monitor from dirt and moisture.
Make sure not to knock or drop the device and that the cuff is
not damaged by sharp objects (needles, scissors etc.).
Do not inflate to above 300 mmHg.
Individual measurements should not exceed a maximum of
2 minutes. There should be an interval of at least 2 minutes
between measurements.
The patient must follow these basic rules when having their
blood pressure measured:
sit comfortably
not cross their legs
rest their back and arms on the chair or another surface
have the centre of the cuff placed on the upper arm so it is
level with their heart
relax as much as possible and not talk while their blood
pressure is being measured
be calm for 5 minutes before the first reading
The following phases are recommended for auscultatory mea-
surement:
adults: phase V (K5)
children aged 3 to 12: phase IV (K4)
pregnant women: phase V (K5), except when sounds are
audible when the cuff is deflated: in this case phase IV (K4)
Korotkoff sounds should be used.
K5 is the point at which tones heard through the stethoscope
are no longer audible. K4 is the point at which tones heard
through the stethoscope change from a clear sound to a muffled
sound.
