Abstract
In a method and breathing apparatus for providing support ventilation to a spontaneously breathing patient a pressure and/or a flow is monitored based on pressure and/or flow measurements, and efforts to inhale or exhale by the patient are detected based on changes in the monitored pressure and/or flow. When a change in the monitored pressure and/or flow indicating an effort to inhale or exhale is detected, the rate of that change is determined and used to calculate a suitable rate of change of pressure applied to the airways of the patient. By changing the applied pressure in accordance with the so determined suitable rate of change, the pressure rise time during inspiration and/or the pressure fall time during expiration can be adjusted to the needs of the patient to ensure efficient and comfortable ventilation.
