Miniature Respiratory Sensor.

Abstract

A miniature Non-Dispersive Infrared (NDIR) sensor suitable for incorporation within the oxygen mask of an aviator has been demonstrated. The sensor utilizes a miniature infrared source. Current is injected into the source in order to alter its' emissivity to produce modulated infrared output. The source was modulated at 2.3 KHz and its' output focused on a cooled lead selenide detector. Data was taken demonstrating the capability of the sensor to detect expired carbon dioxide profiles in a breath by breath manner.
