    Abstract: According to the invention, methods and devices for increasing cardiopulmonary circulation induced by chest compression and decompression when performing cardiopulmonary resuscitation are provided. According to one method, a pressure responsive inflow valve is coupled to a patient's airway. Chest compressions and chest decompressions are performed. During chest decompression the inflow valve prevents respiratory gases from entering the lungs until a certain negative intrathoracic pressure level is exceeded at which time the one inflow valve opens. In this way, the inflow valve assists in increasing the magnitude and duration of negative intrathoracic pressure during decompression to enhance the amount of blood flow into the heart and lungs. Further, the patient is supplied with a pressurized respiratory gas through the inflow valve when the inflow valve opens to ventilate the patient.

    Abstract translation: 根据本发明,提供了在进行心肺复苏时增加由胸部压缩和减压引起的心肺循环的方法和装置。 根据一种方法,压力响应流入阀联接到患者的气道。 执行胸部按压和胸部减压。 在胸部减压期间,流入阀防止呼吸气体进入肺部,直到超过一个流入阀打开一定的负的胸内压力水平。 以这种方式,流入阀有助于增加减压期间负压胸腔内压力的大小和持续时间,以增加进入心脏和肺部的血流量。 此外,当流入阀打开以使患者通气时,通过流入阀向患者提供加压的呼吸气体。
