Patient monitoring system module, multiple-gas

A multiple-gas patient monitoring system module is a specialized component that measures concentrations of gases like oxygen, carbon dioxide, and anesthetic agents in a patient’s inspired or expired air. These modules connect to a breathing circuit—either directly (mainstream) or via a side channel (sidestream)—to provide real-time data critical for respiratory care, anesthesia, and critical care settings.

These modules are designed to integrate seamlessly with a parent monitoring system, plugging into standardized slots to enhance its functionality. Regulation varies by jurisdiction, but they are typically classified based on their intended use and risk level, often requiring compliance with safety and performance standards for medical devices.
