METHODS, SYSTEMS AND DEVICES FOR NON-INVASIVE OPEN VENTILATION FOR PROVIDING VENTILATION SUPPORT
First Claim
1. A system for providing ventilation support to a patient, the system comprising:
- a ventilator;
a control unit;
a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface; and
a nasal interface comprising;
at least one jet nozzle at the distal end of the gas delivery circuit; and
at least one spontaneous respiration sensor for detecting respiration, wherein the at least one spontaneous respiration sensor is in communication with the control unit,wherein the system is open to ambient,wherein the control unit receives signals from the at least one spontaneous respiration sensor and determines gas delivery requirements,wherein the ventilator delivers gas at a velocity to entrain ambient air and increase lung volume or lung pressure above spontaneously breathing levels to assist in work of breathing, andwherein the ventilator delivers ventilation gas in a cyclical delivery pattern synchronized with a spontaneous breathing pattern.

Abstract
A system for providing ventilation support to a patient may include a ventilator, a control unit, a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface, and a nasal interface. The nasal interface may include at least one jet nozzle at the distal end of the gas delivery circuit; and at least one spontaneous respiration sensor for detecting respiration in communication with the control unit. The system may be open to ambient. The control unit may receive signals from the at least one spontaneous respiration sensor and determine gas delivery requirements. The ventilator may deliver gas at a velocity to entrain ambient air and increase lung volume or lung pressure above spontaneously breathing levels to assist in work of breathing, and deliver ventilation gas in a cyclical delivery pattern synchronized with a spontaneous breathing pattern.

14. 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. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. 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. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
