Laboratory assessment of a user-assembled oxygen generation kit.
A laboratory assessment was made of a user-assembled oxygen generation kit designed for use in medical emergencies in the community. Twenty-five kits were studied at five different water temperatures and the rate of oxygen generation and its concentration were measured. The apparatus produced a mean (SD) oxygen volume of 37 (1.98) l which was not affected by the starting water temperature. The mean (SD) rate of flow varied from 2.2 (0.04) l.min-1 at 16 degrees C to 10.3 (2.74) l.min-1 at 40 degrees C but the duration of flow varied inversely. Oxygenation concentrations ranging from 30-51% were produced at starting water temperatures from 22 degrees C-40 degrees C, respectively.
