Breathing circuit gas-sampling/monitoring set

A breathing circuit gas-sampling/monitoring set is a collection of non-sterile components designed to be integrated into a patient’s breathing circuit. It allows for the sampling of expired gases to enable measurements such as end-tidal carbon dioxide, pressure, or flow by connecting to external respiratory monitoring equipment. The set includes a connector with sampling ports and associated sampling tubing, but does not contain any electronic sensors or monitoring devices itself.

This category is defined as a single-use device, meaning it is intended for one patient and one procedure before disposal. As a non-sterile, single-use accessory to breathing circuits, it is regulated as a medical device accessory and is typically supplied without electronic components, relying on connection to external monitors for gas analysis or pressure/flow measurement.
