Latest Medical Compressed Air Standard

The quality standard of medical compressed air is usually stipulated by the national health department or industry standard. In China, the standard of medical compressed air is regulated by the "Hospital Compressed Air Quality Standard" (GB/T 14213-2013). In addition, medical compressed air should also comply with the "Medical Device Supervision and Administration Regulations", "Medical Device Registration Management Measures", "the People's Republic of China and Drug Administration Law" and other relevant regulations.

The quality standard of medical compressed air covers many aspects, including gas composition and quality, microbial contamination, dryness, oil content, ozone content, pressure stability, etc. According to the different scope of use and application requirements, medical compressed air quality standards are divided into three categories: general type, advanced type and ultra-advanced type. Among them, the general type is suitable for clinical applications such as inhalation therapy, ventilator, bedside oxygen inhalation, etc.; the advanced type is suitable for special occasions such as surgery, obstetrics, pediatrics, and intensive care units; the super-advanced type is suitable for some special wards, such as neurosurgery, Cardiac surgery, artificial liver, etc., have very high requirements for air quality.

Specifically, the quality standards of medical compressed air should meet the following requirements:

cleanliness: Medical compressed air must meet the cleanliness requirements, especially in the operating room and intensive care unit and other places that require higher air cleanliness. Substances such as bacteria, fumes, moisture and odors in the air can affect the health of patients, so these pollutants must be filtered out.

Stability: The flow and pressure of compressed air for medical use must be stable and not subject to sudden changes. Because the oxygen gas mixture and anesthetic agent are needed during the operation, if the oxygen flow and concentration change suddenly, it will bring risks to the patient.

Temperature and humidity: The temperature and humidity of compressed air for medical use should be kept within a suitable range. Too high or too low temperature will bring discomfort or danger to patients, and too high or too low humidity in the air will affect the health of patients.

Oil content: The oil content of compressed air for medical use should be less than a certain value, usually less than 0.1 mg/m & sup3;. This is because untreated compressed air may contain oil, which can have an impact on the patient's health.

Microbial contamination: compressed air for medical use must not contain any microorganisms that are detrimental to the health of patients, such as bacteria and actinomycetes. These microorganisms pose a threat to the health of patients.

Other indicators: medical compressed air should also meet the requirements of other indicators, such as carbon dioxide content, market materials, etc. The specific requirements for these indicators may vary according to different standards.

In order to ensure the quality of medical compressed air, hospitals and medical institutions must carry out regular testing. Commonly used detection methods include oil content test, microbial detection and physical parameter detection. Through these detection methods, we can ensure that the quality of medical compressed air meets the relevant standards and requirements, so as to ensure the safety and health of patients.

Please note that the above information is for reference only. In practical applications, the latest national standards and industry standards should be referred to to ensure the quality and safety of medical compressed air. At the same time, relevant practitioners should also receive professional training to improve safety awareness and operational skills to reduce the occurrence of accidents.
