The endobronchial anatomy of 12 lung specimens from horses and 12 healthy, standing, sedated horses was evaluated, using a 200-cm-long, 9.5-mm-diameter videoendoscope. On the basis of these findings, the nomenclature system of Amis and McKiernan was modified for identification of airways of horses during bronchoscopy. Lobar bronchi are identified on the basis of the side of the bronchial tree on which they were found and the order in which they originated from the primary bronchus. Thus, RB1, RB2, and RB3 referred to right cranial lobar bronchus, respectively. On the left side, the designation of LB1 and LB2 refer to the left cranial lobar bronchus and the left caudal lobar bronchus, respectively. Segmental bronchi are identified by consecutive numbers in the order of origination from the lobar bronchus. The direction of the segmental bronchus was denoted by the capital letter D (dorsal), V (ventral), L (lateral), M (medial), R (rostral), and C (caudal). Subsegmental bronchi were identified in the order of origination from the segmental bronchi, using lower case letters (eg, RB2, 1V, a or RB2, 1V, aV). For subsequent branching of the subsegmental bronchi, the branches were numbered consecutively by their order of origination (eg, RB2, 1V, aV, 1D).
使用一根200厘米长、直径9.5毫米的视频内窥镜，对12份马的肺标本以及12匹健康、站立、镇静的马的支气管内解剖结构进行了评估。基于这些发现，对阿米斯（Amis）和麦基尔南（McKiernan）的命名系统进行了修改，以便在支气管镜检查时识别马的气道。叶支气管是根据其在支气管树中的位置以及从主支气管发出的顺序来识别的。因此，RB1、RB2和RB3分别指右颅叶支气管。在左侧，LB1和LB2的命名分别指左颅叶支气管和左尾叶支气管。段支气管是根据其从叶支气管发出的顺序依次编号来识别的。段支气管的方向用大写字母D（背侧）、V（腹侧）、L（外侧）、M（内侧）、R（头侧）和C（尾侧）表示。亚段支气管是根据其从段支气管发出的顺序，用小写字母来识别（例如，RB2, 1V, a或RB2, 1V, aV）。对于亚段支气管的后续分支，这些分支按照其发出顺序依次编号（例如，RB2, 1V, aV, 1D）。
