There is a weak point in the Omron Ultra Premium Automatic Blood Pressure Monitor (Model: HEM-790ITCAN). It is the blood pressure cuff, which tends to form a leak well before the main electronic unit fails. Replacement cuffs cost almost as much as the entire unit, so it's not worth replacing. Trying to find the leak to repair it destroys all the fabric around it! In this video we explore how the BP monitor works, locate the air pump, solenoid valve and look inside the pressure sensor. By seeing the tubing and path that air takes, we can understand how the BP monitor analyzes the pressure curve to detect when it has peaked out, and how it listens for pulsations (first systolic and then diastolic) as the cuff deflates to figure out your blood pressure!
