A combined thermistor, pressure, and CO2 device for use in the sleep laboratory

Project Overview

Currently there are three nasal prongs connected to a child during polysomnography: a resistor to detect temperature difference between inhaled and exhaled air, pressure sensors that show a flattening pressure profile during upper airway narrowing, and CO2 sampling tubes to sense exhaled CO2. This is inefficient and uncomfortable for the child. The goal is to design and develop a prototype that combines these three devices into one apparatus that samples from both the nose and the mouth, and attaches to the child in both a durable and comfortable fashion.
