Abstract: A method for analyzing lunch function includes receiving, at a signal generating device, an output of a respiratory maneuver, where the output of the respiratory maneuver includes one or more respiratory parameters. The method also includes producing, at the signal generating device, a signal corresponding to the output of the respiratory maneuver based on the one or more respiratory parameters, wherein the signal describes one or more characteristics of the respiratory maneuver. The method further comprises transmitting the signal from the signal generating device to a signal receiving device at a remote location over a network.
