AI Technical Summary

Technical Problem

Existing nasal cannulas face challenges in accurately sampling exhaled CO2 from both nasal and oral cavities while delivering oxygen, especially when patients perform everyday activities like speaking, eating, or drinking, as the oral scoop can interfere and dilute the CO2 samples.

Method used

A cannula design featuring movable oral and nasal prongs that transition between configurations to allow for accurate CO2 sampling and oxygen delivery, enabling patients to perform daily activities without interference, by using a movable oral scoop that can be positioned proximate the oral cavity for sampling and rotated away to allow for unobstructed activities.

Benefits of technology

The design allows for continuous and accurate monitoring of exhaled CO2 while enabling patients to engage in everyday activities without interference, ensuring precise oxygen delivery and minimizing sample dilution.

Abstract

A cannula for exhaled gas monitoring includes an exhalation conduit exiting the cannula, first and second nasal prongs each including a channel directing exhaled nasal breath into the exhalation conduit, and a movable oral scoop. The movable oral scoop transitions between a first configuration and a second configuration, wherein the movable oral scoop delivers exhaled oral breath into the exhalation conduit in the first configuration, and reduces delivery of the exhaled oral breath into the exhalation conduit in the second configuration relative to the first configuration.
