ty -jour t1-抽气的可重复性，嗅觉鼻吸气压力和最大灵感压力JF-欧洲呼吸杂志，l au -van melle，g au -fitting，jw y1-1998/04/01 ur -http：//www.qdcxjkg.com/content/content/11/4/901.abstract n2- Twitch suoltwitch n2- Twitch suoltworking（PMO，TW TW，TW）最近提出，在磁性phren性神经刺激和嗅觉鼻腔吸气压力（SNIP）中，作为评估灵感肌肉力量的替代性无创方法。这项研究旨在将其可重复性与正常受试者的最大灵感压力（MIP）进行比较。研究了十名健康受试者，该受试者的功能剩余能力在半核心位置。在轻微到期期间，对符合较小的泄漏的闭塞进行了宫颈磁性神经刺激。通过记录diaphragmmatoratic肌电图来控制刺激的恒定。研究了PMO，TW，SNIP和MIP的压力内部和间可再现性。在1天和1个月后重复进行10次操纵的会议中，对受试者进行了研究。PMO的平均值为16 CMH2O，TW，剪切118 CMH2O，MIP为115 CMH2O。对于这三个测试，与受试者间变异相关的内部受试者变化很小，PMO的类内相关系数范围为0.79-0.90，TW，snip的0.85-0.92，MIP的0.85-0.92。 At 1 day interval, the coefficient of repeatability (2 SD of differences) was 3.6 cmH2O for Pmo,tw, 32 cmH2O for SNIP and 28 cmH2O for MIP. At 1 month interval, the coefficient of repeatability was 5.8 cmH2O for Pmo,tw, 23 cmH2O for SNIP and 21 cmH2O for MIP. We conclude that the within session reproducibility of the new tests twitch mouth pressure and sniff nasal inspiratory pressure is sufficient to be clinically useful. For sniff nasal inspiratory pressure, the between session reproducibility established after 1 day was maintained after 1 month. For twitch mouth pressure, the between session reproducibility declined slightly after 1 month. These characteristics should be considered when using these methods to follow an individual patient over time. ER -
