Medical oxygen is a life-saving gas used in hospitals for patients who have breathing difficulties, low oxygen levels, or serious illnesses. Unlike industrial oxygen, medical oxygen is produced under strict quality standards to ensure patient safety.
Methods of Producing Medical Oxygen
1. Air Separation Process
The most common method involves separating oxygen from atmospheric air. Air contains about 21% oxygen, 78% nitrogen, and small amounts of other gases. Large oxygen plants cool air to extremely low temperatures, turning it into liquid. The different gases are then separated based on their boiling points. The purified oxygen is collected and stored.
2. Pressure Swing Adsorption (PSA)
Many hospitals now use PSA oxygen plants. These plants draw in air and pass it through special filters called molecular sieves. The sieves remove nitrogen and other gases, leaving concentrated oxygen. This method allows hospitals to produce oxygen on-site.
Storage and Distribution
Medical oxygen is stored in cylinders, liquid oxygen tanks, or supplied directly through pipelines installed throughout the hospital. ICU wards, operation theaters, and emergency rooms rely heavily on a continuous oxygen supply.
Importance of Medical Oxygen
Medical oxygen became especially important during the COVID-19 pandemic when millions of patients required respiratory support. It is also used for asthma, pneumonia, COPD, surgeries, and emergency care.
Conclusion
Hospital oxygen is carefully produced, purified, tested, and stored to meet medical standards. Whether generated on-site or supplied through cylinders, medical oxygen plays a crucial role in saving lives every day.
