Abstract: A compact, on-airway, respiratory gas analyzer for performing pulmonary function tests incorporates an IR spectroscopy light guide having a curved, rather than linear, sample chamber that lies transverse to a direction of respiratory gas flow. Cooperating with the sample chamber is an impact plate that functions to steer respiratory and test gases impinging on the impact plate into the curved sample chamber. A source of IR energy is at one end of the sample chamber and an electro-optical sensor responsive to IR energy is disposed at an opposite end of the chamber. The respiratory gas analyzer also includes gas flow paths and valving for carrying out lung capacity and lung diffusion tests.

Abstract translation: 用于执行肺功能测试的紧凑的气道呼吸气体分析仪包括具有横向于呼吸气体流动方向的弯曲而非直线的样品室的IR光谱光导。 与样品室合作是一种冲击板，其用于将撞击板上的呼吸和测试气体引导到弯曲样品室中。 IR能量源位于样品室的一端，并且响应于IR能量的电光传感器设置在室的相对端。 呼吸气体分析仪还包括用于进行肺容量和肺扩散测试的气体流动路径和阀门。
