SYSTEMS AND METHODS FOR TRIGGERING AND CYCLING A VENTILATOR BASED ON RECONSTRUCTED PATIENT EFFORT SIGNAL |
摘要 |
Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a method for respiratory support is described that includes providing a measured pressure, and calculating a net flow based on at least one measured inlet flow and measured outlet flow. A relationship between a first value related to the measured pressure, a second value related to the measured net flow and a third value related to patient effort is used to provide a prediction of patient effort. An interim value is updated based at least in part on the prediction of the patient effort, and used to help compute a patient effort. A ventilation cycle is initiated using the computed patient effort. |

1. A method for respiratory support, the method comprising:
providing a measured pressure; calculating a net flow based on at least one measured inlet flow and at least one measured outlet flow; using a relationship between a first value related to the measured pressure, a second value related to the measured net flow and a third value related to patient effort to provide a prediction of patient effort; updating an interim value based at least in part on the prediction of patient effort; calculating a computed patient effort based at least in part on the interim value; and utilizing the computed patient effort to trigger a ventilation cycle. |
