Publication number: 20100288283Abstract: This disclosure describes systems and methods for adjusting a determination of the amount of breathing assistance a patient requires while on a ventilator. In general, in determining the amount of breathing assistance required, the ventilator takes into account an airflow resistance attributable to the tube used to deliver ventilation to the patient's lungs. A tube compensation factor is calculated using a tube compensation algorithm, or similar equation. In particular, the tube compensation factor represents the resistance to airflow attributable to the breathing tube itself based on, inter alia, frictional drag, turbulence, and an internal diameter of the tube. Changes in the tube during ventilation impact the calculation of the breathing assistance required by the patient and are accounted for when compensating for the breathing tube.Type: ApplicationFiled: May 15, 2009Publication date: November 18, 2010Applicant: Nellcor Puritan Bennett LLCInventors: Shannon E.

Publication number: 20090205663Abstract: 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.Type: ApplicationFiled: February 6, 2009Publication date: August 20, 2009Applicant: Nellcor Puritan Bennett LLCInventors: Joseph Douglas Vandine, Gary Scott Milne
