A patient ventilation system including a ventilation interface and a ventilation source pneumatically coupled to a patient over the ventilation interface is disclosed. 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.

Method and system for operating a patient ventilation device

Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.
