| Device | Required Access | Precalibration Technique | Additional Feature or Drawback |
|---|---|---|---|
| PICCO (Pulsion Medical System, Munich, Germany) | Central venous catheter and arterial line | Transpulmonary thermodilution | Able to calculate ETLV |
| PulseCO (LiDCOLimited, Cambridge, UK) | Peripheral access and arterial line | Lithium indicator dilution | Cannot be used in patients on lithium therapy |
| FloTrac (Edwards Lifescience LLC, Irvine, CA) | Arterial line only | None | More studies to confirm its accuracy are required |
