Abstract

A respiratory face mask has been developed for use with unsedated beagles trained to run on a treadmill. The latex rubber mask, shaped to fit the animal's muzzle, incorporates two modified, commercially available, pulmonary valves for separating inspiratory and expiratory flows. The mask has a dead space of 30 cm3 and a flow resistance below 1 cmH2O . 1(-1) . s. The flexible mask is used to measure breath-by-breath respiratory variables over extended periods of time during rest and exercise.

摘要

一种呼吸面罩已被开发出来，用于与经过训练在跑步机上跑步的未麻醉的比格犬配合使用。这种乳胶橡胶面罩的形状适合动物的口鼻部，包含两个经过改良的市售肺瓣膜，用于分离吸气和呼气气流。该面罩的死腔为30立方厘米，流动阻力低于1厘米水柱·升⁻¹·秒。这种柔性面罩用于在休息和运动期间长时间逐次测量呼吸变量。
