VENTILATOR WITH INTEGRATED OXYGEN PRODUCTION
First Claim
1. A method of providing a breath to a human patient having a patient connection connected by a patient circuit to a ventilator device, the breath having an inspiratory phase with a beginning and an end, the method comprising:
- delivering a bolus of oxygen to the patient circuit at or before the beginning of the inspiratory phase of the breath, the patient circuit delivering the bolus of oxygen to the patient connection;
terminating the delivery of the bolus of oxygen before the end of the inspiratory phase of the breath; and
delivering breathing gases comprising air to the patient circuit before the end of the inspiratory phase of the breath, the patient circuit delivering the breathing gases to the patient connection.

Abstract
A method of providing a breath to a human patient having a patient connection connected by a patient circuit to a ventilator device. The method includes delivering both a bolus of oxygen and breathing gases including air to the patient circuit. The patient circuit conducts the bolus of oxygen and the breathing gases to the patient connection. The breathing gases are delivered before an end of the inspiratory phase of the breath. The bolus may be delivered at or before a beginning of an inspiratory phase of the breath, and the delivery of the bolus may be terminated before the end of the inspiratory phase of the breath. The bolus and breathing gases are delivered to the patient circuit via different ventilator connections that isolate the bolus from the breathing gases before they enter the patient circuit.

19. A ventilator device for use with an oxygen source and a patient circuit configured to receive breathing gases and oxygen to provide a breath to a human patient having a patient connection couplable to the patient circuit, the breath having an inspiratory phase with a beginning and an end, the ventilator device comprising:
-
a compressor configured to deliver breathing gases to the patient circuit; and a control system configured such that; (a) at or before a beginning of an inspiratory phase of a breath, the control system allows the oxygen to flow from the oxygen source to the patient circuit; (b) before an end of the inspiratory phase of the breath, the control system prevents the oxygen from flowing from the oxygen source to the patient circuit; and (c) before the end of the inspiratory phase of the breath, the control system causes the compressor to deliver the breathing gases to the patient circuit. - View Dependent Claims (20, 21)

22. A ventilator device for use with a patient circuit configured to receive breathing gases and oxygen to provide a breath to a human patient having a patient connection couplable to the patient circuit, the breath having an inspiratory phase with a beginning and an end, the ventilator device comprising:
-
a compressor configured to deliver breathing gases to the patient circuit; a patient oxygen outlet couplable to the patient circuit; an oxygen source configured to deliver oxygen to the patient circuit; and a control system configured such that; (a) at or before a beginning of an inspiratory phase of a breath, the control system allows the oxygen to flow from the oxygen source to the patient circuit; (b) before an end of the inspiratory phase of the breath, the control system prevents the oxygen from flowing from the oxygen source to the patient circuit; and (c) before the end of the inspiratory phase of the breath, the control system causes the compressor to deliver the breathing gases to the patient circuit. - View Dependent Claims (23, 24)

25. A ventilation system for use with a human patient having a patient connection couplable to a patient circuit, the system comprising:
-
an oxygen source configured to deliver oxygen to a patient oxygen outlet couplable to the patient circuit; a compressor configured to deliver breathing gases to a ventilator connection couplable to the patient circuit, the ventilator connection being different from the patient oxygen outlet; and a control system configured to; identify an inspiratory phase of a breath; instruct the oxygen source to deliver the oxygen to the patient oxygen outlet before or during the inspiratory phase, the oxygen source being configured to deliver the oxygen to the patient oxygen outlet in response to the instruction to deliver the oxygen to the patient oxygen outlet; and instruct the compressor to deliver the breathing gases to the ventilator connection during the inspiratory phase, the compressor being configured to deliver the breathing gases to the ventilator connection in response to the instruction to deliver the breathing gases to the ventilator connection. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
