Accurate. Just needs proper positioning.
January 25, 2018
I’m a nurse and have been testing this regularly. If you are laying down on your back flat with palm up and hand relaxed, the reading will be perfect, even better than the arm cuff. While sitting up it is more tricky, need to bend your elbow so that the machine is at the same level as your heart, although keep your hand away from the chest, just need to be at the same level height as heart. If you do that the BP will still be accurate, but laying down on your back with arms at your side on the bed and palms up and relaxed is 100% accurate from what I’ve seen.
