<s>[INST] Is a wrist monitor OK to use? [/INST] An upper arm monitor will give you a more accurate reading. All of the studies on blood pressure have been done with measurements from the upper arm rather than the wrist. Wrist monitors involve an extra step because they use a special chip to adjust the reading, as blood pressure is different at the wrist compared to the upper arm.If you still want to use a wrist monitor, follow the instructions carefully as the cuff around the wrist needs to be placed exactly at the level of the heart to give an accurate reading - you will need to rest your arm on a surface for this.
