What is the minimum required oxygen purity for medical applications according to FDA standards?

The minimum required oxygen purity for medical applications, according to FDA standards, is set at 93% oxygen purity. This level of purity ensures that the oxygen supplied for medical use is effective for therapeutic purposes without introducing impurities that could potentially cause harm or interfere with patient treatment.

Medical oxygen is crucial for the treatment of various medical conditions, particularly respiratory issues, and the specified purity level is established to safeguard patient health. At 93% or above, the oxygen concentration is appropriate for direct patient administration and aligns with safety and efficacy standards in healthcare environments.

Understanding this purity requirement is essential for healthcare professionals, oxygen suppliers, and facility compliance with regulatory standards for medical gas systems.
