at least one sensor for acquiring a parameter representative of the operation of the device; and
a battery with energy for powering operations of said first module;
(b) a second module including a central control unit for controlling operation of the first module to generate airway pressure ventilation based on information from said at least one sensor, the second module including an energy source; and
(c) a wireless link between the first module and the second module, the link enabling the energy required for operating the components of the first module to be conveyed from the second module to the first module.
2. The apparatus of claim 1 wherein the at least one sensor comprises a pressure transducer.
3. The apparatus of claim 1 wherein the at least one sensor comprises a flow sensor.
4. The apparatus of claim 1 wherein the breathing connection of the first module comprises a mask.
5. The apparatus of claim 1 wherein each of said first module and said second module include a radio frequency transmitter and receiver for transmission of data of the sensor and control signals for the motor between the first module and the second module.
6. The apparatus of claim 5 , wherein the transmitted control signals to the ventilator control a delivery of airway pressure ventilation in a BPAP mode.
7. The apparatus of claim 5 , wherein the control signals to the ventilator control a delivery of airway pressure ventilation in a CPAP mode.
8. The apparatus of claim 1 wherein said first module comprises a removable component being removably connectable with the breathing connection, said removable component including first and second parts, the ventilator being integrated into the first part, and the at least one sensor being contained in the second part.
9. The apparatus of claim 1 , wherein the ventilator is an axial ventilator.
10. The apparatus of claim 7 , wherein the rotor of the axial ventilator comprises a single stage.
11. The apparatus of claim 8 , wherein the ventilator of the first module is configured to output breathable gas in a substantially parallel directional flow to the input of the breathable gas to the ventilator.
12. A method for providing breathing assistance for a patient, comprising:
(a) providing pressurized breathable gas to a patient with a first module, the first module including:
a source of respiratory pressurized gas, the gas source comprising a ventilator having an inlet rotor and a motor;
a breathing connection for allowing the patient to directly receive the pressurized gas;
at least one sensor for acquiring a parameter representative of the operation of the device; and
a battery with energy for powering operations of said first module;
(b) controlling the first module with a second module, the second module including a central control unit for controlling operation of the first module to generate airway pressure ventilation based on information from said at least one sensor; and
(c) energizing the first module with the second module by a wireless link between the first module and the second module, the link enabling the energy required for operating the components of the first module to be conveyed from the second module to the first module, the second module including an energy source.
13. The method of claim 12 wherein the at least one sensor comprises a pressure transducer.
14. The method of claim 12 wherein the at least one sensor comprises a flow sensor.
15. The method of claim 12 wherein the breathing connection of the first module comprises a mask.
16. The method of claim 12 wherein each of said first module and said second module include a radio frequency transmitter and receiver for transmission of data of the sensor and control signals for the motor between the first module and the second module.
17. The method of claim 16 , wherein the transmitted control signals to the ventilator control a delivery of airway pressure ventilation in a BPAP mode.
18. The method of claim 16 , wherein the control signals to the ventilator control a delivery of airway pressure ventilation in a CPAP mode.
19. The method of claim 12 wherein said first module comprises a removable component being removably connectable with the breathing connection, said removable component including first and second parts, the ventilator being integrated into the first part, and the at least one sensor being contained in the second part.
20. The method of claim 12 , wherein the ventilator is an axial ventilator.
21. The method of claim 20 , wherein the rotor of the axial ventilator comprises a single stage.
22. The method of claim 21 , wherein the ventilator of the first module is configured to output breathable gas in a substantially parallel directional flow to the input of the breathable gas to the ventilator.
