Method And Apparatus For Oxygen Reprocessing Of Expiratory Gases In Mechanical Ventilation

A reprocessing module for oxygen reprocessing of expiratory gases during ventilation of a patient, comprising:

• a carbon dioxide adsorber configured to selectively adsorb carbon dioxide from filtered exhaled air creating product gas with increased oxygen concentration;
• an argon and nitrogen adsorber configured to selectively adsorb argon and nitrogen from the product gas of the carbon dioxide adsorber creating product gas with increased oxygen concentration;
• a threshold testing module configured to measure oxygen concentration of the product gas of the argon and nitrogen adsorber;
• a blending module configured to blend the product gas with room air and/or pure oxygen based on a specified oxygen concentration and to provide the product gas for inspiration.

A graphical user interface for configuring oxygen reprocessing of expiratory gases on a ventilator, the ventilator including a computer having a user interface including the graphical user interface for inputting parameters, the graphical user interface comprising:

• at least one window associated with the user interface;
• one or more selection elements within the at least one window, comprising at least one of:
• one or more input elements for enabling the clinician to input parameters for delivering reprocessed oxygen;
• and
• one or more graphic elements for enabling the clinician to generate graphic displays of data collected during the oxygen reprocessing.
