Guiding therapy by an algorithm based on GEDVI leads to a shortened and reduced need for vasopressors, catecholamines, mechanical ventilation, and ICU therapy in patients undergoing cardiac surgery.

In addition to intravascular volume status SVV is affected by the depth of tidal volume under mechanical ventilation. This influence must be regarded when using SVV for functional preload monitoring.

The MRI unit is a work station where all processes have to be well planned and staff trained to guarantee maximum patient safety, superior quality of imaging and economic needs. For optimal performance trained, experienced and certified personnel, appropriate drugs for the individual patient risk profile and sufficient monitoring equipment are essential.
