A ventilator system comprising: a pressure generating system adapted to generate a flow of breathing gas; a ventilation tubing system including a patient interface for connecting the pressure generating system to a patient ; one or more sensors operatively coupled to at least one of the pressure generating system , the patient , and the ventilation tubing system , wherein the one or more sensors generate output indicative of an inspiration flow; at least one processor ; and a memory for storing and encoding computer-executable instructions that, when executed by the at least one processor is operative to: calculate a first target airway pressure based on a percent support setting, deliver a portion of the first target airway pressure to the patient because the first target airway pressure is truncated in response to an occurrence of a high pressure alarm, characterised in that : the at least one processor is further operative to: in response to the high pressure alarm, reduce the percent setting to form a reduced percent support setting, calculate a second target airway pressure based on the reduced percent support setting, and deliver the second target airway pressure to the patient . a pressure generating system adapted to generate a flow of breathing gas; a ventilation tubing system including a patient interface for connecting the pressure generating system to a patient ; one or more sensors operatively coupled to at least one of the pressure generating system , the patient , and the ventilation tubing system , wherein the one or more sensors generate output indicative of an inspiration flow; at least one processor ; and a memory for storing and encoding computer-executable instructions that, when executed by the at least one processor is operative to: calculate a first target airway pressure based on a percent support setting, deliver a portion of the first target airway pressure to the patient because the first target airway pressure is truncated in response to an occurrence of a high pressure alarm, characterised in that : the at least one processor is further operative to: in response to the high pressure alarm, reduce the percent setting to form a reduced percent support setting, calculate a second target airway pressure based on the reduced percent support setting, and deliver the second target airway pressure to the patient . calculate a first target airway pressure based on a percent support setting, deliver a portion of the first target airway pressure to the patient because the first target airway pressure is truncated in response to an occurrence of a high pressure alarm, characterised in that : the at least one processor is further operative to: in response to the high pressure alarm, reduce the percent setting to form a reduced percent support setting, calculate a second target airway pressure based on the reduced percent support setting, and deliver the second target airway pressure to the patient . in response to the high pressure alarm, reduce the percent setting to form a reduced percent support setting, calculate a second target airway pressure based on the reduced percent support setting, and deliver the second target airway pressure to the patient . <EOS>
