Immediately after airway placement and / or following any patient transfer, an automated program may be activated in a CO2 monitoring device to provide an airway device placement check. The automated program needs time to determine if the airway placement has been successful or not. During analysis of CO2 respiration data by the program, real-time feedback is displayed to the user as soon as the airway check program is activated until the time that a final decision on the success of airway placement is made. The real-time feedback displays one or more indicators of the progress of the program toward a determination of a successful or failed placement.
