A guideline of improving the medical oxygen supply system for COVID-19 and other health emergencies in low- and middle-income countries

Medical oxygen is used by patients in hospital settings for both therapy and life support. Ensuring that patients and healthcare facilities have access to a stable and secure oxygen supply is of utmost importance. The COVID-19 pandemic has highlighted and highlighted the lack of consistent oxygen supply in many hospitals in low- and middle-income countries. Worldwide, the COVID-19 epidemic has brought attention to and made shortcomings in hospital oxygen systems worse. 

For instance, studies conducted in Nigeria revealed that while half of the hospitals had oxygen cylinders on the inpatient wards, the concentrators and cylinders were often empty or broken. The acquisition of oxygen equipment was done in an ad hoc manner, hospital workers lacked proper training and assistance, and preventative maintenance was nonexistent. 

Similar findings have been reported by us and others in Papua New Guinea, Kenya, Uganda, and other African and Asia-Pacific contexts. 


Enhancing hospital oxygen systems must come first, even if ventilator and critical care unit capacities have received a lot of attention.These include methods for: (1) enhancing oxygen consumption and pulse oximetry; (2) streamlining current oxygen delivery systems; and (3) enhancing current oxygen systems with durable components and clever design.

In order to administer oxygen treatment, we require a steady supply of oxygen and quick patient identification. The most common methods for supplying oxygen include liquid oxygen,psa oxygen generators(which concentrate oxygen from air on-site), oxygen cylinders filled at anpsa oxygen plant, and direct piped oxygen(delivered from a specialized gas plant and stored on-site at very high pressure).

Assist Biomedical Engineers to Optimize Existing Oxygen Supplies

Installing straightforward plumbing and individual flowmeters can enhance infection control, efficiency (by allowing numerous patients to use a single oxygen supply), and safety (by enabling individual flow titration). Performing the fundamentals properly is always the key to improving patient outcomes. The COVID-19 pandemic presents a chance to concentrate efforts once again on the fundamentals of acute care, with the knowledge that advances in oxygen therapy (together with infection control, triage, laboratory testing, etc.) will help patients in the short and long term.
