2. Introduction

The Fingertip pulse oximeter is to spot-check oxygen saturation in

blood (SpO

) and pulse rate. The pulse oximeter is used on adults

and pediatric at hospital, clinics, and/or home.

The device contains a dual light source (Red LED and Infrared red

LED) and a photodetector. Bone, tissue, pigmentation, and venous

vessels normally absorb a constant amount of light over time. The

arteriolar bed normally pulsates and absorbs variable amounts of

light during the pulsations. The ratio of light absorbed is translated in

an oxygen saturation measurement (SpO

). Because a

measurement of SpO

is dependent on light from the device,

excessive ambient light can interfere with this measurement.

The wavelength of red LED is 660nm and Infrared LED is

905/880nm with maximum optical output power of 4mW.
