    Abstract: Methods, systems and/or apparatus for slowing a patient's breathing by using positive pressure therapy. In certain embodiments, a current interim breathing rate target is set, and periodically the magnitude of a variable pressure waveform that is scaled to the current interim breathing rate target is increased if the patient's breathing rate is greater than the interim breathing rate target in order to lengthen the patient's breath duration. The magnitude of the pressure increase may be a function of the difference between the interim breathing rate target and the patient's breathing rate. The interim breathing rate target may be periodically reduced in response to the patient's breathing rate slowing down toward the current interim breathing rate target. The variable pressure waveform cycles from an inhalation phase to an exhalation phase when the patient airflow decreases to a cycle threshold, the cycle threshold being a function of flow versus time within a breath and generally increasing with time. Different interim breathing rate targets have different cycle threshold functions, and the cycle threshold functions allow easier cycling as the interim breathing rate targets decrease. Similarly, the variable pressure waveform triggers from an exhalation phase to an inhalation phase when the patient airflow increases to a trigger threshold, the trigger threshold being a function of flow versus time within a breath and generally decreasing with time. Different interim breathing rate targets have different trigger threshold functions, and the trigger threshold functions allow easier triggering as the interim breathing rate targets decrease.

    Abstract: Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.

    Abstract translation: 通过使用正压疗法减缓患者呼吸的方法，系统和/或装置。 在某些实施例中，设定当前临时呼吸速率目标，并且如果患者的呼吸速率大于临时呼吸速率目标，则周期性地增加缩放到当前临时呼吸率目标的可变压力波形的大小，以便 延长患者的呼吸时间。 压力增加的幅度可以是临时呼吸速率目标与患者呼吸频率之间的差异的函数。 临时呼吸率目标可以响应于患者的呼吸速率朝向当前临时呼吸率目标减慢而周期性地减少。 当患者气流降低到周期阈值时，可变压力波形从吸入阶段循环到呼气阶段，循环阈值是呼吸中的流量与时间的函数，并且通常随时间增加。 不同的临时呼吸速率目标具有不同的周期阈值功能，循环阈值功能允许随着临时呼吸速率目标的减少而更容易循环。 类似地，当患者气流增加到触发阈值时，可变压力波形从呼气阶段触发到吸入阶段，触发阈值是呼吸中的流量与时间的函数，并且通常随时间而减少。 不同的临时呼吸速率目标具有不同的触发阈值功能，并且触发阈值功能允许在临时呼吸速率目标减少时更容易触发。

    Abstract: Apparatus and methods provide control for generation of a flow of air to a patient's airways for different respiratory therapies. The pressure and a flow rate may be simultaneously controlled so as to provide a pressure therapy and a flow therapy. The system may include one or more flow generators, in which the control of the pressure and flow rate may include altering the output of one or more of the flow generators and/or an optional adjustable vent. The pressure and flow rate may each be held at a constant. One or both of the pressure and flow rate may also vary in accordance with a desired therapy. The air may be provided via a patient interface that includes a vent to atmosphere, which may be the adjustable vent. The vent may be actuated by a controller to implement the simultaneous control of pressure and flow rate of the air.
