Abstract: Systems and methods for controlling an exhalation valve to increase flow resistance during exhalation. An example method includes delivering breathing gases for a first breath; controlling the expiratory valve according to a first closure profile during a first exhalation phase of the first breath; detecting, by the flow sensor, an exhaled gas flow rate during the first exhalation phase; determining that the exhaled gas flow rate during the first exhalation phase is indicative of a collapsed airway during the first exhalation phase; based on determining that the exhaled gas flow rate is indicative of the collapsed airway, setting a second closure profile of the expiratory valve for a second exhalation phase wherein the second closure profile of the expiratory valve increases airflow resistance for the second exhalation phase of a second breath; and controlling the expiratory valve according to the second closure profile during the second exhalation phase.

Abstract: A ventilator for generating a family dashboard for a patient being ventilated by the ventilator. The ventilator includes a pressure generating system for generating pressurized breathing gases for delivery to the patient and a display coupled to the pressure generating system. The ventilator performs operations including displaying, on the display, a set of ventilation waveforms; detecting a triggering condition for a family dashboard; and based on detecting the triggering condition, removing the ventilation waveforms from the display and displaying, on the display, the family dashboard, wherein the family dashboard includes at least a total ventilator support indicator that indicates an amount of total ventilator support being provided to the patient.
