What is oxygen saturation?
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%, but thoes may be in a danger area:
Those who get cardiovascular and cerebrovascular diseases
Who get disease of respiratory system
Those who love extreme sport
People over the age of 60
Those who work more than 12 hours a day
Those who work in Enclosed environment
Those who often hit the bottle
There is a necessity to test their oxygen saturation regularly.
2014 hot new technology Saturation Meter
Joyful pulse oximeter is a portable professional blood oxygen test machine which has the features of
Operation of the product is simple and convenient
The product is small in volume, lignt in weight (total weight is about 50g including batteries) and convenient in carrying
Power consumption of the product is low and the 2 originally equipped AAA batteries can bbe operated continuously for 20 hours
The product will automatically be powered off when no signal is in the product within 5 seconds
Display Mode: 0.96" Dual-color OLED display
Screen Resolution: 128*64
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.
