As with occasional blood pressure measurement, petechial bleeding can occur
in patients with coagulation disorders or having anticoagulant treatment even
with the correct cuff size.
In patients who have had a single mastectomy, the cuff can be placed on the
opposite arm.
The cuff must not be placed over or near a wound that could cause further injury.
To prevent incorrect measurement results, ensure that the tube is not pinched
or compressed.
A cuff that is applied to a patient in the recumbent or sitting position is normally
located at the same level as the heart. However, if the cuff is located at a level
higher than the heart (for instance if the arm of a patient in bed is lifted), this may
result in lower-than-actual measurement readings (approx. 7.5 mmHg per 10 cm
rise).
The measurement may be inaccurate or impossible:
– if a regular arterial pressure pulse is hard or impossible to detect, e.g. with car-
diac arrhythmias, severe shock, hypothermia or with obesity or an edematous
extremity
– with excessive and continuous patient movement such as shivering or convul-
sion.
