WebH Flow Rate. Flow rate, or peak inspiratory flow rate, is the maximum flow at which a set tidal volume breath is delivered by the ventilator. Most modern ventilators can deliver flow rates between 60 and 120 L/min. Flow rates should be titrated to meet the patient's inspiratory demands.31 If the peak flow rate is too low for the patient ...
