Mar 14, 2007 · The fixed performance systems are predictably better, but only up to 60% oxygen, which may be inadequate. The high flow systems perform well across the circumstances tested. Anxieties about comfort and airway drying may be misplaced . This model could be used to produce realistic tables of oxygen delivery system performance.Author: T. A. J. Wagstaff, N. Soni
