该协议可用于测量小鼠的呼吸模式。重要的是,它可以最大限度地减少转基因菌株中活性行为的影响,从而混淆结果。这种技术的主要优点是,它是无创的,它不要求使用麻醉或压力诱导约束。
首先确保所有软管和管连接到气压表室,并直接将气体流入管和真空流出管连接到气压表扫描室。要校准进入腔室的低流量,请将流入和流出室的流量设置为零,然后拆入腔室的流量管。关闭真空,在低单元中输入零,以记录气压多张计软件的 7700 放大器设置中的零流量。
然后重新连接进气管并打开真空流量以校准高流量,并

Summary
无节制的大气胸膜术用于量化清醒小鼠的呼吸模式。我们显示,在标准化协议下,15 个片段显示的值与延长的安静呼吸持续时间相似。这种方法还允许在造型室的第一个小时内量化呼吸暂停和增强呼吸。
