The puncture is performed after the practitioner has identified the anatomical landmarks and examined the site under ultrasound if necessary. The central venous catheter is placed using the Seldinger technique and the DeltaLong clamp is connected to the Seldinger wire in position. Once positioning has been successfully completed, the Seldinger wire is withdrawn as far as the tip of the catheter. The direct connection to the SwitchBox then allows an intra-atrial ECG to be derived, enabling the practitioner to determine the precise position of the catheter tip.
