New ventilation technique may make liver tumor procedures safer and more precise

This study tested a new way of helping patients breathe during a procedure that destroys liver tumors with heat or electricity. The new method, called flow-controlled ventilation, keeps the diaphragm more still than standard methods, which could help doctors place needles more accurately. 41 adults having liver tumor ablation took part. The goal was to see if the new method works well enough to be used routinely.
