A blood pressure monitor is a device used to measure the pressure of blood in the arteries. It helps individuals track their blood pressure levels, which can indicate overall heart health. These monitors can be manual or automatic, with automatic versions often providing digital readings for easier interpretation. Using a blood pressure monitor is simple. A cuff is placed around the upper arm or wrist, and the device inflates to measure the pressure. Regular monitoring can help detect conditions like hypertension and guide treatment decisions, making it an essential tool for many people, especially those with heart disease.
