Summary

The purpose is to characterize the precision and in use stability of 19 parameters (pH, pCO2, pO2, cNa+, cCa2+, cCl-, cK+, cGlu, cLac, cUrea/BUN, cCrea, ctHb, sO2, FMetHb, FCOHb, FO2Hb, FHHb, FHbF \& ctBil) in arterial blood drawn and stored in self-filling syringes (PICO70 and safePICO) across different lots of samplers measured on ABL90 FLEX PLUS analyzer. The study aims to determine the total (within Lot and Lot-to-Lot) precision for the PICO70/safePICO in arterial whole blood. Furthermore, the study aims to determine the stability for up to 45 min. at room temperature (18-25 °C) for arterial blood sample analysis in the PICO70/safePICO for all 19 parameters.

Detailed description

The study is a Post-Market Clinical Follow-up (PMCF) randomized unblinded study, expected to be conducted at two sites in Denmark using arterial whole blood samples collected from adult patients to determine the precision and stability for the PICO70/safePICO syringes when measuring 19 parameters (pH, pCO2, pO2, cNa+, cCa2+, cCl-, cK+, cGlu, cLac, cUrea/BUN, cCrea, ctHb, sO2, FMetHb, FCOHb, FO2Hb, FHHb, FHbF \& ctBil) using the RMED ABL90 FLEX PLUS analyzer. The 19 parameters will be analysed for each syringe in the syringe series on the ABL90 FLEX PLUS analyzer. For PICO70: Approximately 40+4 (4 contrived sample series) completed series of arterial blood samples consisting of 6 syringes: The syringes will be from three different lots (A,B,C) and analyzed at four different time points, T0, T15, T30 and T45. For safePICO: Approximately 40+4 (4 contrived sample series) completed series of arterial blood samples consisting of 6 syringes: The syringes will be from three different lots (A,B,C) and analyzed at four different time points, T0, T15, T30 and T45. According to guidelines (CLSI GP34) samples should be distributed throughout the analytical measurement range of measurands evaluated. To ensure coverage of the full range for each parameter, it may be necessary to contrive some sample series.

Interventions

Type	Name	Description
DEVICE	Arterial blood samplers with needles PICO70 and safePICO syringes	PICO70 is a self-filling syringe for sample volumes in the range of 0.3-1.5 mL. All syringes are delivered with needle cube for safe needle disposal and a standard tip cap to reduce the risk of blood contact during blood mixing and sample transportation. safePICO is a more advanced group of syringes based on the PICO70 family. They contain a gold coated magnetic steel ball facilitating automatic mixing of the blood when being used with the Radiometer ABL 90 with mixing module. The safePICO is a self-filling syringe covering a volume range of 0.7-1.5 mL and includes a vented safe tip cap (VTC), which simplifies removal of air bubbles and avoid the operator to get in contact with the blood, after attachment to the syringe. Some variants of safePICO are delivered with a needle shield device (NSD) to ensure safe removal of the needle.
