Performance of the reservoir cannulas

The reservoir cannulas (Oxymizer and Pendant) set at 0.5 L/min will achieve an oxygen saturation measured by oximetry (SpO₂) equivalent to continuous flow at 2.0 L/min - an efficency of 4:1. Similarly, 2.0 L/min will achieve an SpO₂ equivalent to continuous flow at 4.0 L/min - an efficiency of 2:1.
