Methods, Systems and Devices for Non-Invasive Open Ventilation For Providing Ventilation Support

A device for providing ventilatory support to a patient, the device comprising:

• a ventilator with a control system;
• a gas supply;
• a nasal interface open to ambient comprising at least one jet nozzle and at least one breathing sensor;
• and
• a gas delivery circuit pneumatically connecting the ventilator to the at least one jet nozzle for delivering ventilation gas, and
• wherein the nasal interface is adapted to locate the at least one breathing sensor in proximity to a nostril entrance, and is adapted to locate the at least one jet nozzle a distance away from the nostril entrance distal to the at least one breathing sensor.

A method for providing ventilation support, the method comprising:

• providing a nasal interface for positioning at least one jet nozzle;
• delivering ventilation gas from a ventilator to a gas delivery circuit in fluid communication with the at least one jet nozzle;
• delivering ventilation gas to a patient nasal airway through the at least one jet nozzle;
• sensing spontaneous respiration with at least one sensor in communication with a control unit;
• determining ventilation gas delivery requirements;
• modifying the delivery of ventilation gas based upon phases of breathing in a cyclical pattern synchronized with the phases of breathing;
• wherein the ventilation gas increases lung volume or lung pressure above spontaneously breathing levels to assist in work of breathing,
• wherein the ventilation gas entrains ambient air, and
• wherein the patient nasal airway is open to ambient.
