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

1. An infant resuscitation system for an infant patient, the infant resuscitation system comprising:
a flow generator configured to generate a flow of breathing gas at a controlled pressure greater than atmospheric pressure, the flow generator configured to output the flow of breathing gas at at least a positive end expiration pressure (PEEP) level and at a peak inspiratory pressure (PIP) level, the PIP level and the PEEP level being adjustable;
a supply tube configured to receive the flow of breathing gas generated by the flow generator and to deliver the flow of breathing gas to the infant patient via a patient interface; and
an actuator moveable between a first position and a second position, the first position causing the flow generator to provide pressure at the PEEP level, and the second position causing the flow generator to raise the pressure to or substantially to the PIP level to deliver a resuscitation breath to the infant patient.
2. The infant resuscitation system as claimed in claim 1, wherein the actuator is a push button arrangement.
3. The infant resuscitation system as claimed in claim 1 or claim 2, wherein the actuator is configured to be manually operated.
4. The infant resuscitation system as claimed in any one of the preceding claims, wherein the actuator comprises a valve body movable between an open position and a closed position.
5. The infant resuscitation system as claimed in any one of the preceding claims, wherein the actuator is used to cause the flow generator to provide repeated resuscitation breaths to the infant patient at or substantially at the PIP level with intervening periods at or substantially at the PEEP level.
6. The infant resuscitation system as claimed in claim 5, wherein the resuscitation breath delivered by the flow generator are at a rate of about 40-60 breaths per minute.
7. The infant resuscitation system as claimed in claim 5 or claim 6, wherein a relative duration of a resuscitation breath time at the PIP level to an exhalation time at the PEEP level can be between 40:60 and 60:40.

8. The infant resuscitation system as claimed in any one of the preceding claims, wherein the actuator is positioned at or on the patient interface.
9. The infant resuscitation system as claimed in any one of the preceding claims, wherein the infant resuscitation system further comprises a pressure relief valve adjustable such that the PEEP level can be adjusted.
10. The infant resuscitation system as claimed in claim 9, wherein the PEEP level of the infant resuscitation system is regulated by the flow generator.
11. The infant resuscitation system as claimed in claim 9, wherein the PEEP level is adjustable within an adjustment range of about 5-70 cmH2O.
12. The infant resuscitation system as claimed in any one of the preceding claims, wherein the infant resuscitation system further comprises an adjustment mechanism that allows the PIP level to be adjusted to a desired pressure level.
13. The infant resuscitation system as claimed in any one of the preceding claims, wherein the flow generator comprises a fan or a blower that generates the flow of air.
14. The infant resuscitation system as claimed in any one of the preceding claims, wherein the infant resuscitation system further comprises a source of breathing gas and the flow generator is configured to receive breathing gas from the source of breathing gas.
15. The infant resuscitation system as claimed in claim 14, wherein the source of breathing gas is or includes ambient air from an environment adjacent the flow generator.
16. The infant resuscitation system as claimed in claim 14 or 15, wherein the source of breathing gas further comprises a gas cylinder or a wall supply.
17. The infant resuscitation system as claimed in claim 16, wherein the infant resuscitation system can utilize supplemental breathing gases from the gas cylinder or wall supply that are blended in combination with the ambient air.
18. The infant resuscitation system as claimed in any one of the preceding claims, wherein the patient interface provides a sealed system that delivers the flow of breathing gas to the infant patient.
19. The infant resuscitation system as claimed in any one of the preceding claims, wherein the infant resuscitation system is further configured to provide CPAP therapy.
20. The infant resuscitation system as claimed in claim 19, wherein one or more resuscitation breath is provided through the patient interface used for the CPAP therapy without requiring removal of the patient interface from the infant patient.
21. The infant resuscitation system as claimed in any one of the preceding claims, wherein the infant resuscitation system is capable of providing PAP or CPAP therapy to a neonate or an infant patient for an extended period of time, while also permitting resuscitation breaths to be delivered to the infant patient if or when necessary.
22. The infant resuscitation system as claimed in any one of the preceding claims, wherein the infant resuscitation system further comprises a humidifier integrated with the flow generator as a single unit, wherein the humidifier receives the flow of breathing gas from the flow generator, the humidifier humidifying the flow of breathing gas to create a flow of humidified breathing gas, and the supply tube receiving the flow of humidified breathing gas from the humidifier and delivering the flow of humidified breathing gas to the infant patient via the patient interface.
23. The infant resuscitation system as claimed in claim 22, wherein the supply tube is a heated supply tube such that a temperature of the flow of breathing gas is maintained at an elevated level within the supply tube to avoid or limit condensation within the supply tube or the patient interface.
24. The infant resuscitation system as claimed in claim 23, wherein a sensor or a probe is able to be coupled to the humidifier and the supply tube to detect the temperature and/or a flow rate of the flow of breathing gas through the supply tube.
25. The infant resuscitation system as claimed in claim 24, wherein the humidifier utilizes information from the sensor or the probe to control at least one operating parameter of the humidifier to maintain the temperature and/or a humidity of the flow of humidified breathing gas within the supply tube within a desired range or at a desired level.
26. The infant resuscitation system as claimed in claim 22, wherein the humidifier comprises a humidifier heater and a humidity chamber, the humidity chamber holds a volume of liquid, such as water, which is heated by the humidifier to create a vapor within the humidity chamber that is transferred to the flow of breathing gas.
27. The infant resuscitation system as claimed in claim 26, wherein the humidifier can be adjusted to a desired temperature and absolute humidity, such as about 37 degrees Celsius and 44 mg/L.
28. The infant resuscitation system as claimed in claim 22, wherein the infant resuscitation system further comprises an expiratory pressure device, wherein gases flow from the patient interface to the expiratory pressure device through an expiratory limb, and the flow of humidified gases is provided to the infant patient through an inspiratory limb.
29. The infant resuscitation system as claimed in claim 28, wherein the expiratory pressure device is configured to provide a minimum pressure or minimum backpressure within the infant resuscitation system at the patient interface, which can be referred to as the positive end expiration pressure (PEEP).
30. The infant resuscitation system as claimed in claim 28 or 29, wherein the expiratory pressure device is a bubbler.
