With the advancement of emergency medicine, blood gas analysis has become an essential monitoring item for critically ill patients, playing a key role in improving the success rate of emergency rescues.

A fully automated blood gas analyzer is a medical instrument used to measure parameters in arterial blood samples from the human body, such as gases (oxygen, carbon dioxide) and electrolytes (such as hydrogen ion concentration, sodium ion concentration). It can provide vital physiological parameters to help medical staff assess the respiratory function, acid-base balance, and electrolyte status of patients, thereby guiding clinical diagnosis and treatment.

Working Principle:

01 Collect arterial blood samples from patients.

02 Place the sample into the reaction pool, where sensors measure parameters such as pH value, oxygen partial pressure, carbon dioxide partial pressure, and electrolyte concentration in the sample through chemical reactions or physical measurement principles. These parameters are converted into electrical signals and transmitted to the electronic control system, which processes the data according to preset algorithms.

03 Calculate the concentration values of blood gas and electrolyte parameters and finally convert them into readable data. The processed test results (such as pH value, oxygen partial pressure, carbon dioxide partial pressure, electrolyte concentration, etc.) will be displayed on the instrument's screen, output as a printed report, or transmitted to the hospital information system.

A fully automated blood gas analyzer must have data processing algorithms to provide high-precision and accurate measurements of blood gas and electrolyte parameters, store test data, generate reports, and output them, support data transmission to the hospital information system, and be equipped with a user interface and operating system for easy viewing of results, data analysis, and recording by medical personnel.

The ARM architecture processor has the advantages of low power consumption, high performance, and rich interfaces. Qiyang, based on the NXP i.MX8M Plus processor, has launched the IAC-IMX8MP-CM core board, which has a wide range of applications in the medical field.
