| The primary aim of this study is to optimize VBG sampling, by testing the accuracy of VBG results obtained through the use of a blood transfer device (BTD). We will evaluate a comprehensive set of blood gas results (pH, bicarbonate, pCO2, pO2, oxygen saturation, lactate, ionised calcium, sodium, chloride, potassium, haemoglobin, FCOHb, FMethHb) from a VBG samples collected via a BTD. We will compare VBG results collected in three different tubes methods by using the same blood draw from an IV line: 1) directly into a blood gas syringe (golden standard referred to as blood gas syringe) 2) into a heparin tube and subsequently transferred to a capillary (referred to as capillary VBG) 3) Into a dummy tube and subsequently transferred to a blood gas syringe via a BTD (referred to as adapter VBG). | — |

| 1. Evaluate influence of a different tube sequence: according to the CLSI and NVKC, tubes should be drawn in a specific sequence as the sequence may influence results. According to this guideline, a VBG should be drawn first in the sequence. However, it would be more practical to take a VBG at the end. We will test whether taking a VBG at the end of the sequence would influence blood gas results. 2. Following the sequence, a conventional VBG is immediately drawn in a blood gas syringe, but it can also be taken from a heparinized tube and then transferred to a blood gas syringe. It is not clear what the effect of heparin is on blood gas results, wherefore it is currently taken in a tube without anticoagulation (dummy tube). However, the use of a heparinized tube will minimize the risk for in vitro blood clotting, that can interfere with results. 3. The effect of storage (room temperature or on ice), time-to analysis and transport (pneumatic tube) have not been adequately described. | — |
