First Claim
1. A method of controlling a ventilation system comprising:
- monitoring a flow of gas between a patient and the ventilation system;
determining a peak expiratory flow rate (PEFR) based on said monitoring;
receiving information indicative of values of a plurality of parameters of an alternating pressure ventilation mode of the ventilation system, the plurality of parameters including at least a higher pressure setting, a lower pressure setting and a duration of the higher pressure setting;
receiving user input indicative of a desired percentage of the PEFR at which the ventilator system should cycle from the lower pressure setting to the higher pressure setting;
programmatically determining a duration of the lower pressure setting based on the desired percentage of the PEFR; and
configuring the ventilation system to automatically cycle between the higher pressure setting and the lower pressure setting at a predetermined flow based on the plurality of parameters and the duration of the lower pressure setting.

Abstract
Systems and methods for configuring the operation of an alternating pressure ventilation mode are provided. According to one embodiment a configuration method includes monitoring gas flow between a patient and a ventilation system. Based on the monitoring, a peak expiratory flow rate (PEFR) is determined Information indicative of values of parameters of the ventilation mode are received, including a higher pressure setting, a lower pressure setting and a duration of the higher pressure setting. User input is also received indicative of a target percentage of PEFR at which the ventilation system should cycle from the lower pressure setting to the higher pressure setting. Based on the target percentage, a duration of the lower pressure setting is programmatically determined. Finally, the ventilation system is configured to automatically cycle between the higher and lower pressure setting at a predetermined flow based on the parameters and the duration of the lower pressure setting.
