Overview
EN ISO 16571:2024/A1:2026 is an important amendment to the international standard for systems used in the evacuation of plume (smoke or vapor) generated by medical devices during surgical and clinical procedures. Issued by CEN and ISO, this standard specifies updated definitions, safety requirements, filtration criteria, and testing methods for plume evacuation systems (PES). These systems protect medical staff and patients from potentially hazardous surgical smoke, improving air quality in healthcare environments.
Key Topics
-
Active Plume Evacuation Systems (Active PES):
Updated definitions clarify that evacuation can occur via endoscopic or laparoscopic ports using external vacuum sources. Systems can be self-powered or use various vacuum sources (mobile, portable, stationary, pipeline).
-
Capture Device:
The amendment defines capture devices as accessories designed to collect plume at its source and transfer it for filtration. These devices can be single-use or reusable.
-
Filtration Performance:
The filtration subsystem must include a particulate filter assembly achieving at least ultra-low penetration air (ULPA) filter efficiency (ISO 29463-1:2024). Pre-filters or adsorbers may also be integrated to enhance filtration capability.
-
Flow Generation & Noise Testing:
Flow-generating components and their filtration subsystems must undergo noise measurement tests to ensure compliance with comfort and safety levels in clinical settings.
-
System Integration and Scope:
When a PES is integrated with other medical equipment, the updated standard specifies that relevant requirements and testing pertain directly to the PES component.
-
Venturi Use Limitation:
For venturi-type airflow generators exceeding 20 liters/min, the amendment states these must not be powered by medical gases, reducing risks of pipeline depressurization.
Applications
Plume evacuation systems are critical for:
- Operating Rooms & Surgical Suites:
Removing plume during electrosurgery, laser surgery, or energy-based procedures that generate airborne contaminants.
- Endoscopic & Laparoscopic Procedures:
The standard offers guidance for ensuring safe plume evacuation within minimally invasive environments.
- Healthcare Facility Compliance:
Supporting hospitals and clinics in meeting occupational health and safety regulations by reducing staff and patient exposure to harmful surgical smoke.
- Device Manufacturing and Quality Assurance:
Providing clear requirements for medical device manufacturers in the design, testing, and integration of PES components for new medical device systems or upgrades.
