MOCACuff is a wrist blood pressure monitor, so correct arm positioning is essential to getting the most accurate results. We recommend crossing your arm over your chest, ensuring MOCACuff is at heart's level -- right around the level of your sternum. You can also rest your wrist on a surface in front of you. However, do make sure your arm is propped up so it's aligned with your heart.We've put together a quick start guide to help you get the most accurate results!https://mocacare.com/assets/media/how_to_use_mocacuff.pdf
