Inhalation/Exhalation Respiratory Phase Detection Circuit |
摘要 |
An apparatus (10) for controlling the pressure of a respiratory gas delivered to a patient includes a phase detection circuit (24) for determining the inhalation and exhalation phases of the patient's respiratory cycle. More particularly, a flow signal representative of the respiratory flow is compared to second signal, offset in time and scaled in magnitude relative to the flow signal, in order to determine the transition from one phase to the next. <IMAGE> |
