NASAL MINUTE VENTILATION AND PEAK INSPIRATORY FLOW IN RESPIRATORY FLOW THERAPY SYSTEMS

Systems and methods determining a nasal minute ventilation and peak inspiratory flow in unsealed respiratory therapy systems. The device can receive data of a parameter of a flow of gases of the respiratory device indicating the patient's respiration. The controller can process the data of the parameter of the flow of gases to remove noise. The controller can determine a device minute ventilation and convert the device minute ventilation to a nasal minute ventilation. The controller can monitor and/or display data relating to at least one of the nasal minute ventilation, nasal minute ventilation rate of change, and nasal minute ventilation trends. The respiratory device can trigger an alarm or notification when at least one of the nasal minute ventilation, the nasal minute ventilation rate of change, and the nasal minute ventilation trends exceeds or falls below a threshold.
