Description:-Please see the attached .pdf file- , Claims:We claim:

1. A combination infant positive airway pressure and resuscitation system, comprising:
an inspiratory pressure device that outputs a flow of breathing gas at a desired peak inspiration pressure;
an inspiratory circuit that receives the flow of breathing gas from the inspiratory pressure device;
a patient interface that receives the flow of breathing gas from the inspiratory circuit, wherein the patient interface is configured to deliver the flow of breathing gas to an infant patient and receive expiratory gases from the patient;
an expiratory circuit that receives the expiratory gases from the patient interface;
an expiratory pressure device that receives expiratory gases from the expiratory circuit and regulates the expiratory gases to a positive end expiration pressure;
an occlusion device within the expiratory circuit upstream from the expiratory pressure device, wherein the occlusion device is configured to permit occlusion of the expiratory circuit at desired times such that the pressure within the inspiratory circuit rises to the peak inspiration pressure.

2. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the expiratory pressure device comprises a water resistance valve.

3. The combination infant positive airway pressure and resuscitation system as claimed in claim 2, wherein the water resistance valve is adjustable to permit adjustment of the positive end expiration pressure.

4. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the occlusion device comprises a manual push button valve.
5. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the occlusion device comprises a clamp.

6. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, further comprising a humidifier positioned within the inspiratory circuit between the inspiratory pressure device and the patient interface.

7. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the occlusion device is located less than 500 millimeters from the patient interface along the expiratory circuit.

8. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the expiratory circuit comprises an expiratory hose coupled to the patient interface and the occlusion device is located within the expiratory hose.

9. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the expiratory pressure device comprises an oscillatory pressure expiratory pressure device.

10. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein the expiratory pressure device comprises an oscillatory valve.

11. The combination infant positive airway pressure and resuscitation system as claimed in claim 1, wherein occlusion device comprises an actuator that actuates a valve moveable between a first position and a second position, the first position causing the pressure in the inspiratory circuit to be delivered at positive end expiration pressure, and the second position causing the pressure within the inspiratory circuit to rise to or substantially to the peak inspiration pressure.

12. A breathing circuit for a combination infant positive airway pressure and resuscitation system, comprising:
an expiratory circuit that is configured for connection to a patient interface to receive expiratory gases from the patient interface;
an inspiratory circuit that is configured for connection to the patient interface to deliver a flow of breathing gas to the patient interface;
an occlusion device configured to permit occlusion of the expiratory circuit at desired times such that the pressure within the system rises above a positive end expiration pressure.

13. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein the expiratory circuit is further configured for connection to an expiratory pressure device that receives expiratory gases from the expiratory circuit and regulates the expiratory gases to a positive end expiration pressure.

14. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein the occlusion device comprises a manual push button valve.

15. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein the occlusion device comprises a clamp.

16. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein the occlusion device is located less than 500 millimeters from the patient interface along the expiratory circuit.

17. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein the occlusion device is located in the expiratory circuit.

18. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein occlusion device comprises an actuator that actuates a valve moveable between a first position and a second position, the first position causing the pressure in the inspiratory circuit to be delivered at positive end expiration pressure, and the second position causing the pressure within the inspiratory circuit to rise to or substantially to the peak inspiration pressure.

19. The breathing circuit for a combination infant positive airway pressure and resuscitation system as claimed in claim 12, wherein the occlusion device is integrated with the patient interface.
