Immediately after airway placement and / or following any patient transfer, an automated program may be activated in the CO2 monitoring device to provide an airway device placement check. Automated procedures take time to determine whether airway placement has been successful or not. During the analysis of the CO2 breathing data by the program, real-time feedback is displayed to the user whenever the airway check program is activated until the moment when a final determination is made regarding the success of the airway placement. The real-time feedback displays one or more indicators of program progress tending to determine successful or failed placements.
