There is a controller that regulates airflow delivery from the ventilation source to the patient according to one or more predefined treatment configuration settings. The controller has an inactive ventilation state, a ventilation initiation state, a treatment state, a treatment suspension state, and a ventilation deactivation state. A display interface is coupled to the controller and configured to generate, exclusively, a device activation user element with the pressure controller in the inactive ventilation state, a fitment feedback indicator and a treatment screen in a ventilation initiation state, the fitment feedback indicator and a treatment status screen in the treatment state, a treatment suspension screen in the treatment suspension state, and a treatment conclusion screen in the ventilation deactivation state. ## Claims ### Claim 1 A patient ventilation system comprising: a patient ventilation interface; a
