Abstract
The systems and methods include controlling pressure and/or flow during exhalation. The systems and methods include novel exhalation for ventilating a patient. The systems and methods decrease the amount of time it takes the patient to passively expire an inspired volume of gas. For example, the systems and method may determine one or more pressure profiles based on one or more criterion and may select and utilize the pressure profile that provides for the fastest rate of lung emptying.
