Product Details
Application and Ordering Notes
This technical note is intended to help engineers, distributors, and purchasing staff understand common compatibility or troubleshooting points before choosing replacement medical accessories.
Product Notes
a common SpO₂ sensor like Mindray 512F is very simple structure.
it consists of a photodetector, an emitter with 660/905nm light.
it detects the light after absorption through detected spot like finger or infant feet.
more complicated sensors like Masimo, Nellcor will build more complicated chips inside the connector for calibrating or identfication so, if a SpO₂ sensor not working we are going to study the materials and the handicrafts procedures.
1, problem from the emitter if you plug the sensor and no light comes, (make sure the machine is in good condition and extension cable in good condition) this problem is usually from the emitter, so you have to replace the sensor 2, problem from the photodetector if you plug the snesor, there is light, but no reading, (make sure the machine is in good condition and extension cable in good condition) usually the problem is from the photodetector 3, also, please check the wires, if there is apparent damage in the wire jacket, try to replace it as soon as possible 4, finally, if you say, ok, this is a new sensor, but it is not working.
