Abstract

The effects of high-frequency airway inflation (HFI) and high-frequency airway deflation (HFD) generated by a triangular pressure pulse generator on pulmonary mechanoreceptors were examined. The cross-correlograms between vagal afferent impulses from the slowly adapting (SAR) and the rapidly adapting receptors (RAR) and the HFI or the HFD pulses were analysed. HFI stimulated SAR and RAR and HFD stimulated RAR, but inhibited SAR. The time lag of the mode in the correlogram between SAR and HFI was shorter than that of the mode in the correlogram between RAR and HFI. The span of the mode and the trough of SAR was shorter than the span of the mode of RAR. This may indicate that the time to peak of the generator potential of RAR is longer than that of SAR.

摘要

研究了由三角压力脉冲发生器产生的高频气道充气（HFI）和高频气道放气（HFD）对肺机械感受器的影响。分析了来自慢适应（SAR）和快适应感受器（RAR）的迷走神经传入冲动与HFI或HFD脉冲之间的互相关图。HFI刺激SAR和RAR，HFD刺激RAR，但抑制SAR。SAR与HFI互相关图中模式的时间滞后短于RAR与HFI互相关图中模式的时间滞后。SAR模式和波谷的跨度短于RAR模式的跨度。这可能表明RAR发生器电位达到峰值的时间比SAR的长。
