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.

11. The method of claim 10 wherein the operation of the nebulizer begins after the modification to the operating condition of the monitoring device.

12. The method of claim 11 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.

13. The method of claim 9 wherein the operating conditions of the medical device and the monitoring device are modified upon receipt of the modification signal.

14. The method of claim 9 wherein the control unit is integrated into the ventilator.

15. The method of claim 14 wherein the medical device includes a control unit, the medical device control unit being integrated into the ventilator.

16. The method of claim 14 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.

17. The method of claim 9 wherein the medical device is an imaging device.

18. The method of claim 9 wherein the medical device is a drug delivery device.

19. The method of claim 18 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.

20. The method of claim 9 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.

21. The method of claim 9 wherein the step of detecting the activation of the respiratory therapy procedure includes detecting either an activation signal from the monitoring device that the monitoring device has initiated a monitoring procedure or an activation signal from the medical device that the medical device has initiated a medical procedure.

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

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

detecting the activation of a respiratory therapy procedure at the control unit; and
