Medical electrical equipment - Capnometers for use with humans - Particular requirements

The SIST EN 864:2000 standard delineates the particular requirements for the basic safety and performance of capnometers—devices that continuously measure carbon dioxide (CO2) concentrations in human breath.

Capnometers are vital in operating rooms, intensive care, and emergency medicine, where real-time CO2 monitoring informs critical decisions. The standard applies to devices used with adults, children, and neonates, excluding those used for transcutaneous monitoring and research applications.

Key aspects covered include:

• General safety provisions based on IEC 60601-1, with specific focus on CO2 measurement
• Functional criteria: responsiveness, display accuracy, alarm systems
• Marking and labeling for safe clinical operation
• Electrical, mechanical, and environmental safety

Compliance ensures that capnometers provide timely, accurate readings, supporting better patient outcomes and workflow efficiencies.
