Oxygen saturation

Oxygen is carried in the blood attached to haemoglobin molecules. Oxygen saturation is a measure of how much oxygen the blood is carrying as a percentage of the maximum it could carry.One haemoglobin molecule can carry a maximum of four molecules of oxygen, if a haemoglobin molecule is carrying three molecules of oxygen then it is carrying 3/4 or 75% of the maximum amount of oxygen it could carry.The range of oxygen saturation for a healthy individual is between 92-100%.

Principles

Principle of the oximeter is as follows: an experience formula of data process is established taking use of Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin (HbO2) in glow and near-infrared zones.

Operation principle of the instrument is: photoelectric Oxyhemoglobin Inspection Technologe is adopted in accordance with Capacity Pulse Scanning and Recording Technology, so that 2 beams of different wavelength of lights can be focused onto human nail tip through perspective clamp finger-type sensor.then measured signal can be obtained by a photosensitive element, information acquired through which will be shown on screen through treatment in electronic circuits and microprocessor.
