Two Air Supply Methods of Blood Gas Analyzer

Two air supply methods of blood gas analyzer are as follows:
The blood gas analyzer provides two gases PCO2 and PO2 two kinds of electrodes used in the calibration. Each gas containing different proportions of oxygen and carbon dioxide. Blood gas analysis instrument air system of medical devices are divided into a compressed gas cylinder supply mode (also known as external gas distribution mode) and the gas mixer air supply method (also known as gas distribution mode).
First, the blood gas analyzer, compression cylinder gas
By the supply of the two compressed gas cylinders, one containing 5% carbon dioxide and 20% oxygen; the other containing 10% carbon dioxide, no oxygen. Equipped with a pressure reducing valve on the cylinder, the gas output after decompression, after humidifier saturated wet first, and then the valve or the switching device to the measuring chamber, PCO2 and PO2 electrode calibration. The steam humidifier will set the standard gas saturation humidification device.
Second, the blood gas analyzer, gas mixer air supply method
This supply system with blood gas analysis instrument itself, the gas mixer to produce a calibration gas. Sent added to the gas mixer up the air compressor to produce compressed air and gas cylinders of pure carbon dioxide gas, carbon dioxide purity requirements than 99.5%, the gas mixer, the two gas ratio, mixing, and finally resulted in a similar above the proportion of gas in the cylinders of two different concentrations of gases. The same cylinder premixed gas, these two gases but also by the humidifier was given to measuring capillary.
