This study was undertaken to determine whether oscillations superimposed on a regular ventilatory pattern influence the arterial blood gases and pH and the airway pressures at adequate alveolar ventilation at the onset of inhibition of inspiratory activity. The peak, mean and end-expiratory airway pressures were therefore measured at inhibition of this activity with and without superimposition of oscillations on the ventilatory pattern. It was found that superimposed oscillations lowered the airway pressure only at a low ventilatory frequency, whereas inhibition occurred at almost equal arterial PCO2 and pH values with and without superimposed oscillations on the ventilatory pattern.
本研究旨在确定叠加在规则通气模式上的振荡是否会在吸气活动抑制开始时，在充分肺泡通气的情况下影响动脉血气、pH值和气道压力。因此，在通气模式上有或无振荡叠加的情况下，在这种活动受到抑制时测量了峰值、平均和呼气末气道压力。结果发现，叠加振荡仅在低通气频率时降低气道压力，而在通气模式上有或无振荡叠加的情况下，抑制发生时的动脉PCO2和pH值几乎相等。
