Abstract

A network enabled flow generator includes a continuous source of breathable gas for delivery to airways of a patient, and a process controller processing data relating to operations of the flow generator. A network interface communicates with the process controller and is configured to support a communications protocol. In this manner, patient data can be more easily accessed, and the flow generator can be more easily maintained via access through a network such as the Internet.

15. A method according to claim 14, wherein the step of generating an e-mail communication is further practiced by sending the e-mail communication via the network interface to at least one of a physician, an SMS gateway for relay into a mobile phone network, an Internet maintained database, and a sleep lab service center with Internet connectivity.

16. A method according to claim 14, wherein the step of generating an e-mail communication is further practiced by sending the e-mail communication via the network interface to at least one of a service center to notify a fault occurrence detected by a process controller and an Internet connected server that logs usage/compliance and efficacy data to a database.

17. A method according to claim 10, wherein the storing step comprises storing at least one of images and programs relating to operations of the flow generator, the method further comprising referencing the images and/or programs in web pages delivered to the web browser on the remote computer, the images and applets being loadable into the web browser using standard HTTP.

18. A method according to claim 10, wherein the enabling step is practiced by connecting the flow generator to a health facility local area network.

19. A method according to claim 18, further comprising monitoring the data via a central workstation at the health facility, and generating alerts based on the data.

20. A method according to claim 10, wherein the enabling step is practiced by connecting the flow generator with a user'"'"'s home network.

21. A method according to claim 20, wherein the home network includes a home computer running a software program for analyzing the data relating to operations of the flow generator, the enabling step comprising enabling the home computer to analyze the data and access information on patient care based on the analyzed data.

22. A method according to claim 10, wherein the enabling step is practiced by connecting the flow generator to a local area network that includes an Internet gateway, the flow generator periodically communicating with an Internet connected server to determine if a later version of flow generator operating software is available for download, and if so, downloading the operating software.
