초록 ▼

A method for ventilating a patient with a ventilator includes consecutively delivering a plurality of substantially equal volume amounts into a closed ventilator circuit during a ventilator self-test, receiving a pressure measurement for each volume delivery, calculating a change in pressure for each volume delivery, consecutively releasing a plurality of substantially equal volume amounts from the closed ventilator circuit during the ventilator self-test, calculating a change in pressure for each volume release, fitting the calculated change in pressure data for volume delivery and volume release to an inhalation non-linear model equation and an exhalation non-linear model equation, respectively, deriving one or more inhalation tubing compliance compensation coefficients from the inhalation non-linear model equation, and deriving one or more exhalation tubing compliance compensation coefficients from the exhalation non-linear model equation.

1. A ventilator system comprising: a pressure generating system adapted to generate a volume of breathing gas;a ventilation tubing system including a patient interface for connecting the pressure generating system to a patient;at least one sensor operatively coupled to at least one of the pressure generating system and the ventilation tubing system;a ventilator self-test, the ventilator self-test configured to: consecutively deliver a plurality of substantially equal volume amounts into a closed ventilator circuit; andconsecutively release a plurality of substantially equal volume amounts from the closed ventilator circuit;a loss effect compensation module, the loss effect compensation module configured to: receive a pressure measurement for each volume delivery and each volume release from the ventilator self-test;calculate a change in pressure for each volume delivery and each volume release;fit the calculated change in pressure data for each volume delivery and each volume release to an inhalation non-linear tubing compliance model equation and an exhalation non-linear tubing compliance model equation, respectively;derive one or more inhalation tubing compliance compensation coefficients from the inhalation non-linear tubing compliance model equation; andderive one or more exhalation tubing compliance compensation coefficients from the exhalation non-linear tubing compliance model equation; anda processor in communication with and controlling the pressure generating system, the at least one sensor, the ventilator self-test, and the loss effect compensation module. 2. The ventilator system of claim 1, wherein the loss effect compensation module is further configured to estimate an inhalation tubing compliance compensation volume by inputting the one or more inhalation tubing compliance compensation coefficients into a loss effect adjusted tubing compliance model. 3. The ventilator system of claim 2, wherein the loss effect compensation module is further configured to add the estimated inhalation tubing compliance volume amount to an inspiratory tidal volume amount and provide an instruction to deliver the combined amount to a patient through the ventilation tubing system. 4. The ventilator system of claim 1, wherein the loss effect compensation module is further configured to estimate an exhalation tubing compliance compensation volume by inputting the one or more exhalation tubing compliance compensation coefficients into a loss effect adjusted tubing compliance model. 5. The ventilator system of claim 4, wherein the loss effect compensation module is further configured to estimate an expiratory tidal volume of a patient by subtracting the exhalation tubing compliance compensation volume from a total expiratory volume. 6. The ventilator system of claim 1, wherein the loss effect compensation module is further configured to estimate a circuit resistance by estimating at least one circuit resistance parameter from an equation utilizing the one or more inhalation or exhalation tubing compliance compensation coefficients and utilizing the estimated circuit resistance parameter in an equation for estimating circuit resistance. 7. The ventilator system of claim 1, wherein the loss effect compensation module is further configured to estimate a patient lung compliance by estimating at least one patient lung compliance parameter from an equation utilizing the one or more inhalation or exhalation tubing compliance compensation coefficients and utilizing the estimated patient lung compliance parameter in an equation for estimating patient lung compliance. 8. The ventilator system of claim 1, wherein the loss effect compensation module is further configured to estimate a patient lung compliance by estimating at least one patient lung compliance parameter from an equation utilizing the one or more inhalation or exhalation tubing compliance compensation coefficients and utilizing the estimated patient lung compliance parameter in an equation for estimating patient lung compliance.
