The environment or operational factors which can affect the performance of the device and/
or its blood pressure reading (e.g. common arrhythmias such as atrial or ventricular prema-
ture beats or atrial fibrillation, arterial sclerosis, poor perfusion diabetes, age, pregnancy,
pre-eclampsia, renal diseases, patient motion, trembling, shivering).
Measurements should be taken at appropriate intervals. Frequent measurements with short
intervals may lead to pressed arm, reduced blood flow, low blood pressure, and result in an
inaccurate reading.
It is recommended that the measurements are taken in intervals of more than two minutes.
Before use, empty the cuff until there is no residual air inside.
Do NOT allow the cuff to twist or bend.
Do NOT twist the cuff hose or put heavy things on it.
Please hold the connector of the hose while connecting and disconnecting it to the device.
If arrhythmia or auricular fibrillation occurs, take measurement again.
The patient should sit or lay down with calm condition and make the cuff and the patient's
heart on the same level to get accurate measurement. Other positions may lead to inaccurate
measurement.
