Abstract

A method for controlling flow rate of gas comprising: delivering gas flow to patient at operating flow rate, and at intervals, receiving or determining, based on data from one or more sensors, first and second patient parameters indicative of patient's respiratory rate and heart rate, determining first status of respiratory rate based on first patient parameter and the first patient parameter received or determined at one or more previous intervals, determining second status of heart rate based on second patient parameter and the second patient parameter received or determined at one or more previous intervals, determining whether to adjust or maintain the operating flow rate based on first and second status, and based on determining that operating flow rate be adjusted, adjusting operating flow rate by an increment, and based on determining that operating flow rate be maintained, maintaining operating flow rate at the present operating flow rate.
