Non-rebreathing valve, single-use

Non-rebreathing valves are single-use medical devices designed to control airflow in breathing circuits, ensuring patients inhale fresh oxygen or air while preventing exhaled gases from being re-breathed. They’re commonly used in emergency care, anesthesia, and respiratory therapy to improve oxygen delivery efficiency during procedures like mask ventilation or CPR.

These devices are typically classified as single-use and may vary in materials (e.g., silicone, rubber) and valve mechanisms. Regulation and supply depend on jurisdiction, with compliance often tied to safety standards for respiratory aids and sterile/non-sterile classifications. Always verify local requirements before use or procurement.
