Using Pressure Sensing to Reduce Blood Pressure

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Using Pressure Sensing to Reduce Blood Pressure

Blood pressure measurements can alert a person of the presence of hypertension or high blood pressure and monitor blood pressure on an ongoing basis. Besides daily medication, the usual recommendations to reduce blood pressure are: lose weight, abstain from smoking, follow a healthy diet and perform regular physical activity, such as walking or swimming. Among the newer actions that a person can take is performing a limited amount of focused isometric therapy using a handgrip device.

Research studies have shown that less than 1 hour per week of isometric exercise with a handgrip can lower the resting systolic blood pressure of hypertensive patients by about 10 mmHg. One manufacturer of an isometric tool suggests performing the exercise once a day for 5 days a week in 12-minute sessions. When a hand grip is squeezed, the device displays a score with a reading of 100 being the target but progress indicated by improvements toward that goal. Typically, a hand dynamometer indicates a grip force providing biofeedback by measuring pressure and converting the measurement to force based on the pressure applied to known area (P = F/A). A user’s true progress is confirmed by blood pressure measurements using any of the commonly available devices.
