Abstract
In a method for adjusting a ventilation mask, a ventilative state is measured of a ventilation mask that is placed over a respiratory opening of a patient. A sealing portion of the ventilation mask is for establishing a fluid seal between the ventilation mask and the patient. The sealing portion comprises a plurality of bladders. An unintentional leak of the fluid seal is determined based on a measured change of the ventilative state. A bladder of the plurality of bladders is adjusted to seal the unintentional leak.
