A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

The resolution will determine the overall quality of the video. Full HD or 1080p (1920×1080) is standard for dash HD cams. Dash cameras may have 1080p, 1296p (common for Chinese dashcams), 1440p, or higher definition for a front camera and 720p for a back camera and include f/1.8 aperture and night vision mode.
Conventional pulse oximetry assumes that arterial blood is the only blood moving (pulsating) in the measurement site. However, during patient motion, the venous blood also moves, which can cause conventional pulse oximetry to under-read SpO 2 levels because it cannot distinguish between the arterial and venous blood.
