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.
