Tracheal microcirculation was studied in six healthy anesthetized adult mongrel dogs. A transparent balloon was used to apply pressure to the tracheal mucosa during observation of the microcirculation. Pressures of microvascular occlusion were measured using an electrically callibrated silicone, envelope placed on the observation balloon. The different vessel sizes were measured and classified using the operating microscope. Capillary occlusion pressures ranged from 10 to 40 msurements of tracheal diameter were performed. Progressive local and generalized dilatation occurred. Capillary occlusion pressure was lower in the more dilated specimens. The lower than expected occlusion pressures are thought to be a result of the tracheal dilatation and may be related to the administration of drugs or other factors.
对6只健康的成年麻醉杂种犬的气管微循环进行了研究。在观察微循环期间，使用一个透明气球对气管黏膜施加压力。使用置于观察气球上的经电校准的硅胶套测量微血管闭塞压力。使用手术显微镜测量并分类不同血管大小。进行了10至40次气管直径测量。出现了渐进性局部和全身性扩张。在扩张更明显的标本中，毛细血管闭塞压力较低。低于预期的闭塞压力被认为是气管扩张的结果，可能与药物给药或其他因素有关。
