A gases humidification system includes a measuring chamber and a mixing chamber. The mixing chamber has one or more mixing elements that improve a mixing of gases before reaching the measuring chamber. Ultrasonic sensing is used to measure gases properties or characteristics within the measuring chamber. A baffle or a vane may be used to control and direct the gases flow through the mixing chamber as the gases flow moves into the measuring chamber.

Gases mixing and measuring for a medical device

This invention relates to a method or system for providing an indication or establishment of airway patency of a patient comprising monitoring of at least one targeted gas (e.g. CO2, N2 or may be other gases capable of being detected, monitored, and measured) that is being expired or being expelled from an airway of a patient (e.g. an apnoeic or non-spontaneously breathing patient), and based on measurements of the at least one targeted gas for a period of time, providing an indicator as to an output of the measurements of the at least one targeted gas for the period of time, or a determination as to airway patency, or a determination as to a location of a blockage or obstruction in the airway, or combinations of these.
