EQUIPMENT GUIDE

The main oxygen concentrators with built-in compressors are the Respironics M10 and Drive DeVilbiss, both capable of delivering up to 10L/min. These units are often donated due to their availability to many patients. They're relatively inexpensive and easy to find parts for, making them a great choice. Stick to main retail brands—while foreign oxygen concentrators exist, our evaluation shows that the price reduction, quality standards, and shipping logistics don't currently make them viable options. Prices for these units, once very high during COVID, have now normalized to regular retail levels, if not slightly less.

Of note, if you are looking for a small 1-2L oxygen concentrator there is the Inogen G3, 1.2 These are a premium technology so they can range between 3-4k, however do provide some concentrated oxygen on the go.

Our second recommendation is the EverFlo concentrator. These are slightly cheaper but only deliver up to 5L/min. However, two portable generators can be connected in series to increase the flow rate and FiO2. These are fantastic for attaching to standalone ventilators to boost patient FiO2, and can help off-grid systems elevate from 50% to 100% FiO2.

High flow humidified nasal oxygen has gained popularity recently due to the COVID crisis. The main units are Vapotherm and Airvo 2, capable of delivering 40-60L/min. These units are typically used as a last-ditch effort to avoid intubation, but they can be utilized in the field and run on E-cylinders. They require humidification, making them challenging to maintain and use in the mission field due to the need for specific tubing and cartridges. Prices for these units have dropped significantly post-COVID, and they are now staples in treating various respiratory pathologies beyond COVID.

By choosing the right oxygen concentrators and ensuring proper maintenance, mission hospitals can effectively support patients with respiratory needs, providing reliable and versatile oxygen therapy solutions.
