ABL90 FLEX: Instructions for use
1
Introduction Intended use
The ABL90 FLEX analyzer is a portable, automated analyzer that measures pH, blood gases, electrolytes, glucose, lactate, bilirubin and oximetry in whole blood. The ABL90 FLEX analyzer is intended for use by trained technologists, nurses, physicians and therapists. It is intended for use in a laboratory environment, near patient or point-of-care setting. The ABL90 FLEX analyzer can be connected to the RADIANCE system. The RADIANCE system enables communication between the RADIANCE server and the ABL90 FLEX analyzer to allow remote data entry and analyzer access. These tests are only performed under a physician's order. In the table below the measured parameters are shown: Parameter group
Parameter
pH/blood gas:
pH (acidity) pCO2 (carbon dioxide tension) pO2 (oxygen tension)
Oximetry:
ctHb (total hemoglobin concentration) sO2 (oxygen saturation) FO2Hb (fraction of oxyhemoglobin in total hemoglobin) FCOHb (fraction of carboxyhemoglobin in total hemoglobin) FHHb (fraction of deoxyhemoglobin in total hemoglobin) FMetHb (fraction of methemoglobin in total hemoglobin) FHbF (fraction of fetal hemoglobin) ctBil (concentration of total bilirubin in plasma)
Electrolytes:
cK+ (potassium ion concentration) cNa+ (sodium ion concentration) cCa2+ (calcium ion concentration) cCl- (chloride ion concentration)
Metabolites:
cGlu (D-glucose concentration) cLac (L(+)-lactate concentration)
