Evaluation of a method for isocapnic hyperventilation : a clinical pilot trial
Background: Isocapnic hyperventilation (IHV) is a method that shortens time to extubation after inhalation anaesthesia using hyperventilation (HV) without lowering airway CO 2 . In a clinical trial on patients undergoing long-duration sevoflurane anaesthesia for major ear–nose–throat (ENT) surgery, we evaluated the utility of a technique for CO 2 delivery (DCO 2 ) to the inspiratory limb of a clo
