Medical Oxygen: Understanding the oxygen supply chain against the corona virus
Medical oxygen has been the focus of global attention since the world was hit by the outbreak of the coronavirus (Covid-19) and health care systems reached their limits. Maximize health and we can be sure that this will happen.
Oxygen is one of the main gases in the air and most of it is produced through the air separation process in ASU (Air Separation Unit).
In general, ambient air is composed of 78% nitrogen, 21% oxygen (approximately) and 1% argon and other compounds (eg rare gases such as krypton, neon and xenon). An ASU takes this abundant atmospheric air and divides it into separate components (oxygen, nitrogen, argon) during several stages of separation and distillation.
The oxygen produced by the refrigeration process is usually produced with a purity of more than 99% so that it can be used for virtually all purposes, including medical purposes. Medical oxygen is considered as a medicine or pharmaceutical product in the healthcare sector. The oxygen produced by the air separation process is acceptable as medical oxygen without any additional purification steps. The air separation process removes the contaminants themselves below the levels required to achieve the medical oxygen profile. Although some air separation facilities may allocate some of the oxygen produced to medical oxygen tanks, this is not a universal process and is not necessary. The oxygen produced by the air separation process is acceptable as medical oxygen due to the nature of the process.
Many air separation plants generate oxygen in a shared tank, then use laboratory equipment to ensure that the products meet the desired specifications. In the case of medical oxygen, this laboratory equipment is also used to generate test results, which allows a qualified person to release the product for use as acceptable medical oxygen. Must have the necessary license to produce oxygen.
Oxygen is one of the most important life-saving gases that is widely used in medicine today. It has been used in medicine since the 1800s and has advanced greatly in both application and delivery system.
Medical oxygen is used to restore tissue oxygen stress in conditions such as respiratory arrest, cardiac arrest, shock, carbon monoxide poisoning, and heavy bleeding, and is used in hospitals and emergency departments.
The use of medical oxygen outside the hospital environment has become so widespread that thousands of people depend on portable medical oxygen technologies in their daily lives. In addition, medical oxygen is critical in emergency response units, first aid, resuscitation, and support equipment – even modern anesthesia techniques rely on medical oxygen.
In the Covid-19 epidemic, oxygen is used in its most important form in medicine – in respiration, accident response and life support. And it is very effective in providing oxygen to patients and keeping their vital functions active.
Oxygen in the medical sector is traditionally produced in ASUs (s) and then distributed to the customer as a liquid or as a gas through cylinders.
There is an alternative means of producing oxygen in the medical market, which is in the form of pressure fluctuation absorption (PSA). Hospitals are usually connected to the medical gas network for medical oxygen supply. Depending on their consumption, they can buy the liquid oxygen stored on site in bulk refrigeration tanks and feed it to the center through its pipelines, or buy cylinders.
With the bulk supply through storage tanks and pipelines into the wards, it usually supplies the required volume of medical oxygen well. However, it is not uncommon to find a combination of bulk supply and cylinder – and especially in these epidemic conditions – whereby the amount of oxygen required can exceed the pipeline’s ability to deliver. The cylinder supply can both supplement the piping capacity and provide a relatively mobile supply.
Oxygen cylinders come in a variety of sizes to provide continuous or required oxygen flow. Hospitals typically use these cylinders to ensure easy placement in the hospital, whether in the patient’s bedside, operating or procedural wards, MRI rooms, or even on mobile equipment. This flexibility, which exists in various medical applications, has not only led to the popularization of oxygen cylinders in the hospital environment, but can also be very important in responding to the consequences of patients infected with the coronavirus at any time.
Medical oxygen cylinders are also used by the first responders, paramedics and emergency services, who are at the forefront of the crisis. For example, ambulances often use light and stationary oxygen cylinders for service. Small medical oxygen cylinders used by emergency personnel are common when responding to emergencies and treating patients. The first respondents working in temporary wards outside the hospital or in urban areas will also depend on these cylinders.
PSA systems use commonly available components that can greatly reduce the initial capital required compared to oxygen refrigeration and provide a portable type that meets the different needs of the hospital and healthcare department. .
Priestley Gas Industries is committed to supporting its customers in the face of the unprecedented COVID-19 epidemic. Our response teams ensure that we deliver industrial gases to our customers safely and efficiently.
In addition, the Priestley gas industry prioritizes the supply of oxygen and essential medical gases to support hospitals, physicians, nurses, and medical professionals caring for COVID-19 patients.
