A smaller portable unit to supply a single patient with room air based BiPAP is also under development. This is in contrast to the manifold feed system which was conceived initially.

Oxygen supplementation to each patient is via an individual oxygen supply flow valve and meter at the patient’s station, allowing independent oxygen flow rate adjustment. Once again maximum oxygen feed concentrations depend on patient’s tidal volumes, the level of pressure support dialled in and the amount of oxygen injected. Typically, this is up to a maximum of 60%O2.

Pressure is supplied by a 220V industrial air pump rated for medical use feeding into the mechanical BiPAP system developed by UMOYA.
