Ventilation system employing synchronized delivery of positive and negative pressure ventilation
First Claim
Patent Images
1. A ventilation system, comprising:
- a device structured to deliver positive pressure ventilation and negative pressure ventilation to a patient; and
a controller structured to cause the device to deliver a desired total pressure ventilation to the patient by synchronizing delivery of both a particular positive pressure ventilation and a particular negative pressure ventilation to the patient during an inhalation phase.

Abstract
A ventilation system is adapted to synchronize the delivery of both positive pressure ventilation and negative pressure ventilation to a patient. The ventilation system is structured to produce a positive pressure flow of gas which is delivered to the patient'"'"'s airway and a negative pressure flow of gas which is converted into a negative extrathoracic pressure. The negative extrathoracic pressure is communicated to the patient in synchronism with the delivery of the positive pressure flow of gas.
