Evaluation of six oxygen concentrators.
Examples of six oxygen concentrators (DeVO2, Dom 10, Econo 2, Hudson, Permox, and Roomate) were evaluated over a 9-28 day period to determine (1) the oxygen yield (% O2) over the flow range 1-4 l min-1; (2) 90% oxygen rise time (90% RT) from a cold start when they were operated at 2 l min-1; (3) accuracy and readability of the flow device; (4) static outlet pressure; (5) major components compri...
متن کاملOxygen concentrators: a primary oxygen supply source.
PURPOSE Efforts to harmonize the standards of the CSA and the ISO, as they relate to compressed medical gas supply and piping, prompted us to review ten years experience with oxygen concentrators (OCs) in Canada used as a primary hospital oxygen supply. The goals of this study were; 1) To document the number of Canadian OC Hospital sites, 2) to define what impact these units have had on medical...
متن کاملTechnical and clinical assessment of oxygen concentrators.
One membrane oxygen enricher (Oxygen Enrichment Company OE-4E) and four molecular sieve (MS) concentrators (Mountain Medical Econo2, De Vilbiss MINI DeVO2, Cryogenic Roomate III, and Mountain Medical Mini O2) have been studied to assess technical and clinical performance. During four weeks of continuous operation at a flow rate of 2 l min-1 (6 l min-1 for OE-4E) consistent oxygen levels were de...
متن کاملPerformance comparison of 4 portable oxygen concentrators.
BACKGROUND Several portable oxygen concentrators (POCs) have become available in the United States. Technical trade-offs are made in designing POCs, so their performance is expected to differ. METHODS We tested 4 POC models (Invacare XPO(2), Respironics EverGo, AirSep FreeStyle, and Inogen One) for oxygen delivery as a function of respiratory rate. We measured oxygen volume per pulse, pulse d...
متن کاملPrescription of oxygen concentrators: adherence to published guidelines.
The indications for the prescription of oxygen concentrators have been assessed in 82 patients against the Department of Health guidelines, except that only one set of blood gas and spirometry measurements was required if the patient's condition was stable. Of the 49 patients recommended for this treatment by a chest physician, 41 (82%) fulfilled the requirements, compared with only 11 of 33 pa...
