DIY medical equipment is not a big hobby area but this DIY Pulse Oximeter is one cool device. I have no idea what a commercial Pulse Oximeter but like anything medical the real stuff that is used in hospitals usually costs big bucks. In this case your finger is slipped between two pieces of medical grade oak to take the reading. The project is based around the powerful 68HC908AB32 microcontroller.
Thanks Maciek
“A pulse oximeter is a medical device that indirectly measures 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 photoplethysmograph. It is often attached to a medical monitor so staff can see a patient’s oxygenation at all times.”

Have you not read the disclaimer on the last page of the data sheet? your not allowed to use the 68HC908AB32 in medical equipment, so if you die then its your own fault lol.
