From: Hemodialysis catheter insertion: is increased PO2 a sign of arterial cannulation? A case report
1- | Do not remove the catheter |
2- | Attach a pressure transducer to the catheter and discriminate between venous and arterial waveforms* |
3- | Perform blood gas analysis (high PO2 is suggestive of arterial blood)** |
4- | Obtain Chest X-ray (frontal and lateral) |
5- | If still in doubt, obtain Computed Tomography Angiography*** |
6- | Surgical or endovascular intervention if arterial cannulation is confirmed |
