To achieve synchronized differential pulmonary ventilation, an Ohio 560 ventilator was modified through separation of the outputs of the deep breath bellows and the tidal volume bellows and providing independent volume, flow rate, PEEP, oxygen-humidification, and alarm systems. The described ventilator modification is simple, inexpensive, and does not alter the performance characteristics of the original unmodified ventilator. Differential lung ventilation may be more easily achieved with this modified ventilator than with the simultaneous use of two ventilators or external electronic synchronizers.
为实现同步差异肺通气，对一台俄亥俄560型呼吸机进行了改装，方法是将深呼吸波纹管和潮气量波纹管的输出分开，并提供独立的容量、流速、呼气末正压、氧湿化和报警系统。所描述的呼吸机改装方法简单、成本低，且不会改变原始未改装呼吸机的性能特点。与同时使用两台呼吸机或外部电子同步器相比，使用这种改装后的呼吸机可能更容易实现差异肺通气。
