Abstract
A method of controlling a ventilator to provide spontaneous breathing support includes determining a target CO2 value, determining a support pressure, detecting a patient-generated spontaneous breath, and delivering ventilation gas to the patient based on the support pressure. A patient CO2 is then measured, along with measuring at least one of a patient breath rate and a breath volume. The patient CO2 is compared to the target CO2 value. The patient's respiratory drive is determined based on at least one of the patient breath rate and the breath volume. If elevated respiratory drive is detected, then the support pressure is adjusted accordingly. If elevated respiratory drive is not detected, then the target CO2 value is adjusted based on the measured patient CO2.
