Integrated multimodal colorimetric based aspiration detection and intubation placement verification system and method

Abstract

An integrated multimodal colorimetric based aspiration detection and intubation placement verification system for an endotracheal tube and associated method includes a housing configured to be coupled to the endotracheal tube whereby patient exhalation can flow through an internal passage of the housing, and colorimetric based sensors within the housing and configured to come into contact with the patient exhalation, where the colorimetric based sensors are visible from the exterior of the housing, and wherein the colorimetric sensors include at least two of i) CO2 sensor, ii) a sensor for a first gastric acid, iii) a sensor for a second gastric acid different from the first gastric acid, and iv) a PH sensor. An associated method is disclosed. The integrated multimodal colorimetric based system can be used with other respiratory devices other than endotracheal tubes.
