Abstract

A method for integrating a ventilator device with a monitoring device and other medical devices that allows the function of the monitoring device and medical devices to automatically change based on initiation of a respiratory therapy procedure. In addition, modification of behavior on the part of the ventilator is automatic in response to activation of a medical procedure from the medical device or the monitoring device.

2. The method of claim 1 wherein the operating condition of the monitoring device is modified upon receipt of the modification signal.

3. The method of claim 1 further comprising the steps of:

detecting the cessation of the respiratory therapy procedure; and

automatically modifying the operating conditions of the monitoring device and the ventilator in response to the cessation of the respiratory therapy procedure.

4. The method of claim 3 wherein the step of automatically modifying the operating conditions of the monitoring device and the ventilator upon cessation of the respiratory therapy procedure includes returning the monitoring device and the ventilator to the operating conditions prior to activation of the next respiratory therapy procedure.

5. The method of claim 1 wherein the step of detecting the activation of the respiratory therapy procedure includes detecting an activation signal from the monitoring device that the monitoring device has initiated a monitoring procedure.

6. A method of integrating the operation of a ventilator, a monitoring device including a second control unit and a medical device to perform a respiratory therapy procedure, the method comprising the steps of:

providing a control unit in communication with the ventilator, the monitoring device and the medical device;

detecting either an activation signal from the monitoring device indicating that the monitoring device has initiated a monitoring procedure or an activation signal from the medical device indicating that the medical device has initiated a medical procedure; and

generating a modification signal from the control unit to the second control unit to automatically modify an operating condition of the medical device and an operating condition of the monitoring device in response to the activation of the respiratory therapy procedure wherein the second control unit is located remote from the control unit.

7. The method of claim 6 wherein the medical device is a nebulizer and the respiratory therapy procedure includes the activation of the nebulizer to deliver an aerosolized drug into a flow of ventilation gas from the ventilator, wherein the operating condition of the monitoring device is modified to prevent the intake of the ventilation gas during the respiratory therapy procedure.

8. The method of claim 7 wherein the operation of the nebulizer begins after the modification to the operating condition of the monitoring device.

9. The method of claim 8 wherein the control unit generates a second modification signal upon termination of the respiratory therapy procedure, wherein the monitoring device and the nebulizer return to their initial operating conditions upon receipt of the second modification signal.

10. The method of claim 6 wherein the operating conditions of the medical device and the monitoring device are modified upon receipt of the modification signal.

11. The method of claim 6 wherein the control unit is integrated into the ventilator.

12. The method of claim 11 wherein the medical device includes a control unit, the medical device control unit being integrated into the ventilator.

13. The method of claim 11 wherein the medical device includes a control unit remotely located from the ventilator, wherein the ventilator control unit communicates to the medical device control unit over a communication link.

14. The method of claim 6 wherein the medical device is an imaging device.

15. The method of claim 6 wherein the medical device is a drug delivery device.

16. The method of claim 15 wherein the operating condition of the drug delivery device is modified such that the drug delivery device operation is synchronized with the operation of the ventilator to more effectively deliver the drug.

17. The method of claim 6 wherein the method includes the step of automatically modifying an operating condition of the medical device in response to the cessation of the respiratory therapy procedure.

18. A method of integrating the operation of a ventilator and a medical device, the method comprising the steps of:

providing a first control unit integrated into the ventilator and in communication with a second control unit of the medical device, wherein the second control unit is remotely located from the first control unit of the ventilator;

detecting the activation of a medical procedure at the first control unit; and

generating a modification signal from the first control unit to the second control unit to automatically modify an operating condition of the ventilator and an operating condition of the medical device in response to the activation of the medical procedure.

19. The method of claim 18 further comprising the steps of:

detecting the cessation of the medical procedure at the first control unit; and

automatically modifying the operating condition of the ventilator in response to the cessation of the medical procedure.

20. The method of claim 18 wherein the step of detecting the activation of the medical procedure includes detecting an activation signal from the medical device that the medical device has initiated the medical procedure.

21. The method of claim 18 wherein the medical device is an imaging device, wherein the activation of the medical procedure is initiated at the imaging device.

22. The method of claim 21 wherein upon initiation of the medical procedure, the operating condition of the ventilator is adjusted to optimize the medical procedure.

23. The method of claim 18 wherein the medical device is a drug delivery device.
