Abstract

A system and a method for synchronizing operation between a patient monitoring device and a patient treatment device are disclosed. The patient monitoring device and the patient treatment device are operatively connected via a network, for example, a patient area network (PAN) or a local area network (LAN). A controller with a display is configured to accept user input via a graphic user interface (GUI) and display a patient'"'"'s physiological data and operating parameters of both the patient monitoring device and the patient treatment device. The operation is synchronized by starting to operate the patient monitoring device at a predetermined operating state of the patient treatment device, and delaying changes in the operating state of the patient treatment device, until the operation of the monitoring device is concluded or the operating state of the patient treatment device indicates an abort condition.

Claims

1. A method for synchronizing operation between a patient monitoring device and a patient treatment device, comprising the steps of:

Detecting an initial status of the patient treatment device;

Starting a procedure with the patient monitoring device in response to the initial status;

Continuously monitoring an operating status of the patient treatment device while the requested procedure is performed; and

Terminating the procedure, if the operating status of the patient treatment device indicates an abort condition.

2. The method of claim 1, further comprising the steps of:

Detecting an impending event of the patient treatment device while monitoring the operating status, and

Delaying the event until the procedure is complete, or until the operating status of the patient treatment device indicates an abort condition.

3. The method of claim 2, wherein the patient treatment device comprises a ventilator.

4. The method of claim 3, wherein the procedure comprises acquisition of an image with an imaging device.

5. The method of claim 3, wherein the procedure comprises measurement of an intrathoracic blood pressure.

6. The method of claim 5, wherein the intrathoracic blood pressure is a pulmonary arterial pressure (PAP) or a pulmonary capillary wedge pressure (PCWP).

7. The method of claim 3, wherein the initial status of the ventilator indicates completion of inspiration or expiration.

8. The method of claim 3, wherein the impending event of the ventilator is expiration, if the initial status indicated completion of inspiration, or inspiration, if the initial status indicated completion of expiration.

9. The method of claim 3, wherein the abort condition indicates at least one of violating a lower threshold for SpO₂, reaching a presettable apnoeic time T_apn, and reaching a lower limit value for a minute volume.

10. A system for synchronizing operation between a patient monitoring device and a patient treatment device, the system comprising a controller operatively connected to the patient monitoring device and the patient treatment device, said controller configured to

Detect an initial status of the patient treatment device;

Start a requested procedure with the patient monitoring device in response to the initial status;

Continuously monitor an operating status of the patient treatment device while the requested procedure is performed; and

Terminate the procedure, if the operating status of the patient treatment device indicates an abort condition.

11. The system of claim 10, wherein the patient monitoring device comprises at least one of an imaging device, a pulmonary arterial pressure measuring device, and a pulmonary capillary wedge pressure measuring device.

12. The system of claim 10, wherein the patient treatment device comprises a ventilator.

13. The system of claim 12, wherein the ventilator is configured to provide inspiration and expiration, and wherein the initial status of the patient treatment device indicates completion of one of inspiration and expiration.

14. The system of claim 12, wherein the ventilator is configured to provide inspiration and expiration, and wherein the operating status of the patient treatment device indicates

that expiration is imminent or an inspiration time has been exceeded, if the initial status indicated completion of inspiration, or

that inspiration is imminent or an expiration time has been exceeded, if the initial status indicated completion of expiration.

15. The system of claim 12, wherein the abort condition indicates at least one of a violation of the lower threshold for SpO₂, reaching a presettable apnoeic time T_apn, and reaching a lower limit value for a minute volume.

16. The system of claim 10, further comprising an operator console having a display device, said display device configured to display physiological patient data and parameter settings from the patient monitoring device and the patient treatment device and receiving user input via a graphic user interface (GUI).
