Abstract

An integrated ventilation system is presented. The integrated ventilation system comprises a high frequency ventilation module configured to be operationally coupled to a ventilation system, where the high frequency ventilation module is configured to aid the ventilation system in performing high frequency ventilation. A method for providing high frequency ventilation via use of a high frequency ventilation module, where the high frequency ventilation module is configured to be operationally coupled to a ventilation system, and where the high frequency ventilation module is configured to aid the ventilation system in performing high frequency ventilation, is presented. The method includes creating a vacuum effect at an outlet port of the ventilation system to aid in active exhalation of gas from a patient.
