GE Healthcare has recently become aware of a potential safety issue wherein the Oxygen and Air wall or
tank inlet fittings on the back panel, were reversed during assembly. As a result, this may potentially
have reversed Air/Oxygen gas concentrations; for example, a setting of 100% Oxygen could have an
output of 21% Oxygen, and vice versa. The settings of the blender knob will no longer be accurate in the
affected units.
