摘要
A method of providing high frequency ventilation to a patient, comprises delivering a flow of breathing gas to the patient, the flow of breathing gas having a first positive pressure level and a second positive pressure level, the first and second positive pressure levels alternating with one another in a plurality of cycles in the flow of breathing gas to have a frequency and an amplitude, the flow of breathing gas to the patient generating a mean airway pressure; determining whether the patient is breathing spontaneously or is trying to breath spontaneously; and, in response to the determination that the patient is breathing spontaneously or trying to breath spontaneously or according to the user settings for HFV and user intervention for non-spontaneous breathing patient, adjusting the mean airway pressure, modulating the frequency and duty cycle of the flow of breathing gas, or modulating the level of flow and pressure amplitude of the breathing gas, or two or more thereof.
