Claim Text:
1. A method of controlling bolus delivery in a pulse flow oxygen concentration system for a patient, comprising: providing a pulse flow oxygen concentration system that comprises a rotary valve assembly that rotates with respect to a plurality of adsorption beds to selectively transfer fluids through the plurality of adsorption beds in order to concentrate oxygen gas from compressed air, the pulse flow concentration system delivering the concentrated oxygen gas to the patient in boluses having a pulse bolus duration, the pulse flow oxygen concentration system including an open control with a user interface for controlling the pulse bolus duration, the pulse flow oxygen concentration system being combined with a continuous flow oxygen concentration system that provides a continuous flow of oxygen to the patient; determining one or more respiratory conditions of the patient; and adjusting the open control to adjust the pulse bolus duration in accordance with the determined one or more respiratory conditions of the patient, the adjusting of the pulse bolus duration including presenting to a remote user a default total inspiratory time and a default percent inspiratory time, and accepting an adjustment to both the default total inspiratory time and the default percent inspiratory time from the remote user, and then the oxygen concentration system calculating a proper pulse length and flow rate to deliver a predetermined pulse volume but with a different pulse duration corresponding to the percent inspiratory time and the total inspiratory time adjusted by the remote user, the user interface being connected to the oxygen concentration system via a wireless communication network comprising at least one serial link, the user interface being operated at a location remote from the patient.
