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

An integrated multimodal colorimetric based aspiration detection system for a respiratory device comprising:

• a) A housing having an inlet coupling and an outlet coupling coupled directly to a disc shaped central chamber, wherein the inlet coupling is configured to be coupled to the respiratory device whereby patient respiratory exhalation can flow through a valveless internal passage passage of the housing formed by the inlet coupling the central chamber and the outlet coupling;
• b) Colorimetric based sensors within the housing and configured to come into contact with the patient exhalation within the disc shaped central chamber, where the colorimetric based sensors are visible from the exterior of the housing, and wherein the colorimetric sensors includes at least two of i) a 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.
