Patent number: 8146591Abstract: Disclosed is a capnometry apparatus for receiving respiratory gas from a respiratory cannula positioned on a patient. An integrated host controller alerts a user if the capnometry apparatus is connected or not connected to the respiratory cannula based in part on a signal output from a capnometer located in the capnometry apparatus. The host controller also includes the functionality to shut off the capnometer pump with or without a time delay when the capnometer signal output indicates the capnometer pump is not connected to the cannula. An ambient-air pressure sensor located in the capnometry apparatus alerts the host controller if the capnometry apparatus has been moved to a new location with a substantially different altitude than the first location, in which case the host controller will issue an alert to a user prompting a calibration of the capnometry apparatus.Type: GrantFiled: June 21, 2005Date of Patent: April 3, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Paul J. Niklewski, Mark A. Burdorff, William T. Donofrio, Curt R. Eyster, James F. Martin, Anil K. Nalagatla, William P. Adair, Nicholas E. Cobb
