Controlled mechanical ventilation (CMV) is routinely used in equine anaesthesia, with many different options available to mechanically deliver breaths. The complexity of respiratory pathophysiology in anaesthetised horses and the wide range of devices available is described in this scoping review. The first part of the review outlines basic equine respiratory physiology and pathophysiology during anaesthesia to illustrate what makes horses prone to inefficient gas exchange and ventilation when they are recumbent. The difference between spontaneous ventilation and CMV is reviewed and basic considerations of CMV are explored in more detail.

马麻醉中的受控机械通气：生理背景和基本考虑（第 1 部分）

受控机械通气 (CMV) 通常用于马麻醉，有许多不同的选项可用于机械呼吸。本范围审查描述了麻醉马呼吸病理生理学的复杂性以及可用设备的广泛范围。评论的第一部分概述了麻醉期间马的基本呼吸生理学和病理生理学，以说明是什么使马在卧位时容易出现低效的气体交换和通气。回顾了自主通气和 CMV 之间的区别，并更详细地探讨了 CMV 的基本考虑。
