A combined oxygen concentrator and compressed air unit: Assessment of a prototype and discussion of its potential applications
A prototype combined oxygen concentrator and air compressor is described. Laboratory assessment demonstrated satisfactory oxygen concentrations, flows, pressures and reliability. Its various modes of use in clinical practice are described. It is likely to be a valuable method to provide oxygen for anaesthesia both in remote areas and where nitrous oxide‐free anaesthesia is required, as well as a reliable alternative to commercially produced oxygen for therapeutic purposes.
