Abstract

A ventilator monitoring system is described for monitoring a plurality of ventilators. In one embodiment, a server including a dedicated ventilator application program for each type of ventilator, monitors a plurality of heterogeneous ventilators over a wireless network.

Claims

1. A ventilator monitoring system comprising:

a plurality of ventilators, wherein at least two of said ventilators are heterogeneous types, said ventilators having data;

a first network access point in communication with one of said plurality of ventilators, said first network access point passing requests to and receiving data from said one of said plurality of ventilators;

a network in communication with said first network access point;

a second network access point in communication with said network;

a server in communication with said second network access point, said server comprising;

a dedicated ventilator application program for each type of heterogeneous ventilators; and

a listener/pollster;

a database in communication with said server, said database comprising data from said plurality of ventilators; and

a browser in communication with said server;

wherein said listener/pollster transmits requests to and receives data from said plurality of ventilators through said second data access point and passes requests to and data from said dedicated ventilator application program,

wherein said dedicator ventilator application passes data to and receives data from said database, and

wherein said browser receives data from said server and displays data to a user.

2. The system of claim 1 wherein said network is a wireless Ethernet network.

3. The system of claim 1 wherein said data received by said browser comprises standard HTML output.

4. The system of claim 1 wherein said ventilator communicates with said network access point by way of an RS232 connection.

5. The system of claim 1 wherein the protocol of the network is TCP/IP.

6. The system of claim 1 wherein said data comprises ventilator settings.

7. The system of claim 1 wherein said data comprises patient values measured by said ventilator.

8. The system of claim 1 wherein said data comprises alarm conditions detected by said ventilator.

9. The system of claim 1 further comprising a router in communication between said server and said second network access point.

10. The system of claim 1 wherein the listener/pollster comprise a plurality of threads.

11. The system of claim 10 wherein said plurality of threads comprise a receive thread and a load thread.

12. The system of claim 1 wherein said browser communicates with said server by way of said network.

13. A ventilator monitoring system comprising:

a plurality of ventilator means, wherein at least two of said ventilator means are heterogeneous types, said ventilator means having data;

first network access means for communicating with one of said plurality of ventilator means, said first network access means passing requests to and receiving data from said one of said plurality of ventilator means;

network means for communicating with said first network access means;

second network access means for communicating with said network means;

server means for communicating with said second network access means, said server means comprising;

a dedicated ventilator application means for each type of heterogeneous ventilator means; and

a listener/pollster means for transmitting requests to and receiving data from said plurality of ventilator means through said second data access means and for passing requests to and data from said dedicated ventilator application means;

database means for passing data to and receiving data from said server means and for storing data from said plurality of ventilator means; and

browser means for receiving data from said server means and for displaying data to a user.

14. A method for monitoring a plurality of patients comprising:

providing a plurality of ventilators, wherein at least two of said ventilators are heterogeneous types;

collecting data from said plurality of ventilators via a dedicated ventilator application for each of said ventilator types;

transmitting said data via a network to a server said server comprising a dedicated ventilator application program for each type of heterogeneous ventilator, and a listener/pollster,

storing said data in a database; and

displaying said data on a web browser.

15. The method of claim 14 wherein said step of displaying said data comprises the steps of generating HTML output from said data and reading said HTML output with said web browser.

16. The method of claim 14 wherein said step of displaying data further comprises customizing said data according to data trends.
