We would recommend a BP machine with an arm cuff rather then a wrist one, these can be purchased from a chemist or online and are affordable. Please watch this video for instructions on how to complete your blood pressure measurement. The picture below will help you understands the readings produced from the machine.
How to take and record your Blood Pressure Readings:
a) It is important to take your blood pressure when you are seated and not talking
b) Take 2 readings at least a minute apart mornings and evening and record the lowest of the two readings each time
c) Record these below
d) If your machine records the pulse rate also record this
e) Fill in the name of the patient, date of birth and telephone contact (only use one form per patient)
f) The Message box is optional, please use if you think we should know about anything significant such as if you have had to stop any of your medicines
