What are Heart-Rate and Oxygen Saturation?

Heart-rate is the speed at which your heart pumps blood through your body. Pulse oximetry is a noninvasive
method of determining saturation of oxygen in your blood. However, this is a peripheral measurement is not
always a direct reflection of the arterial oxygen saturation (SaO ), but two are correlated enough for clinical
purposes. There are a multitude of applications for these measurements; especially, in the medical field.

Here are some examples of studies using HR monitoring and pulse oximetry:
