Controlled mechanical ventilation (CMV) is routinely used in equine anaesthesia, with many different options available to facilitate the delivery of mechanical breaths. The complexity of equine respiratory pathophysiology and the wide range of devices available is described in the two parts of this scoping review. The second part of this review provides an overview of commercially available and hand-made devices that can be used to deliver CMV in large animals. A short overview of basic physics for mechanical ventilation is given. Working principles are discussed and, where relevant, connected to the pathophysiological background of equine ventilation. The objective of this review is to demystify ventilation modes and ventilators used in equine anaesthesia over the last two decades. In addition, this review aims to provide a practical guide to what the anaesthetist needs to consider before using CMV, how CMV can be delivered and monitored, and which principles need to be applied are included. Comparison of the clinical effects between spontaneous breathing and CMV is included.

马麻醉中的受控机械通气：呼吸机的分类和实际考虑（第 2 部分）

控制机械通气 (CMV) 通常用于马麻醉，有许多不同的选项可用于促进机械呼吸的传递。马呼吸病理生理学的复杂性和广泛的可用设备在本范围审查的两个部分中进行了描述。本综述的第二部分概述了可用于在大型动物中递送 CMV 的市售和手工制造设备。简要概述了机械通气的基本物理学。讨论了工作原理，并在相关的情况下与马通气的病理生理学背景联系起来。这篇综述的目的是揭开过去二十年来马麻醉中使用的通气模式和呼吸机的神秘面纱。此外，本综述旨在为麻醉师在使用 CMV 之前需要考虑的事项、如何输送和监测 CMV 以及需要应用哪些原则提供实用指南。包括自主呼吸和 CMV 之间临床效果的比较。
