RADIOMETER ABL90 FLEX - Oximetry Parameters

ABL90 FLEX reference manual 7. Performance characteristics
7-25
The substances against which the oximetry parameters (ctHb, sO
2
, FO
2
Hb, FCOHb,
FMetHb, FHHb, FHbF) and ctBil were tested for interference are given in the table
below:
(SAT100 blood reference test sample:
ctHb = 15 g/dL, sO
2
= 100 %, FCOHb = 0.7%,
FMetHb = 0.5%, ctBil = 0, pH = 7.4. Parameter sensitivity from the influence on the
absorbance spectrum from various substances.)
