The smart shoe, uses pulse oximetry on the hallux i.e. big toe to indirectly monitor the saturation and volume of your blood. This parameter is used to understand how oxygen passes through different parts of the body. This is a multi-modal sensing shoe and captures the heart rate through the foot on the dorsalis pedis artery.
Asthma and Congestive Heart Failure (CHF) are two chronic conditions that currently benefit from monitoring heart rate and oxygen saturation. A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally a lower heart rate at rest implies a more efficient heart function. The oxygen level from pulse oximetry is reasonably accurate but does not measure carbon dioxide levels. Improving your SP02 levels can be done by exercise, fresh air, consuming acids, breathing properly, and avoiding drugs and alcohol.
