To measure blood pressure, the wrist must be squeezed by the cuff hard enough to temporarily stop blood flow
through the artery. This may cause pain, numbness or a temporary red mark to the wrist. This condition will appear
especially when measurement is repeated successively. Any pain, numbness, or red marks will disappear with time.
Measuring blood pressure too frequently may cause harm due to blood flow interference. Check that the operation
of the device does not result in prolonged impairment of blood circulation, when using the device repeatedly.
