Patent number: 10842443Abstract: This disclosure describes systems and methods for monitoring and evaluating data associated with ventilatory parameters to detect expiratory airflow limitation in a ventilated patient. For example, a ventilator may monitor flow and/or pressure during ventilation of the patient.
