Breathing circuit multi-parameter sensor

A breathing circuit multi-parameter sensor is a reusable device designed to be attached to a patient’s breathing circuit to detect and convert respiratory gas properties into electrical signals. These signals are sent to a parent monitoring device, which uses them to measure and display multiple respiratory parameters such as gas flow, temperature, and sometimes pressure or humidity, supporting real-time assessment of ventilatory support.

As a reusable transducer, this category of device is intended for repeated use after appropriate cleaning and disinfection, and it functions as a component that interfaces with a larger respiratory monitoring or ventilatory system. Its regulation depends on the jurisdiction and the risk classification of the parent device it supports, but it is not a standalone diagnostic or therapeutic device—it enables measurement by transmitting data to the parent unit for processing and display.
