High Frequency Jet Ventilation for Percutaneous Interventional Radiology

High Frequency Jet Ventilation for Percutaneous Interventional Radiology

Evaluate benefits of High Frequency Jet Ventilation compare to standard ventilation during general anesthesia in patient undergoing peri diaphragmatic percutaneous tumor ablation.

The investigators hypothesis that procedure is shorter and more accurate in High Frequency Jet Ventilation group reducing target movement induced by ventilation.
