ISO 80601-2-67:2020

Overview

ISO 80601-2-67:2020 is the particular standard in the IEC/ISO 80601 series that defines basic safety and essential performance requirements for oxygen‑conserving equipment. It applies to active medical electrical (ME) devices that conserve supplemental oxygen by delivering gas intermittently and synchronized with the patient’s inspiratory cycle - typically used in the home healthcare environment by lay operators. The standard clarifies the differences between oxygen‑conserving (bolus) devices and continuous flow oxygen (CFO) systems and requires standardized performance testing and labelling to avoid misinterpretation of dose settings.

Key topics and requirements

• Scope and definitions: Applies to conserving equipment and manufacturer‑intended accessories whose characteristics affect safety or performance. Excludes non‑active devices (e.g., reservoir cannulas).
• Basic safety & essential performance: Establishes mandatory requirements for safe operation and clinically relevant performance of oxygen‑conserving ME equipment.
• Standardized performance testing and labelling: Requires consistent test methods and clear labelling so users and clinicians can compare conserving devices and understand dose settings versus continuous flow.
• Identification, marking & documentation: Guidance on user information, symbols, and labelling tailored to lay operators and clinical settings (Annex C & D provide marking/labelling guidance).
• Electrical, mechanical and thermal protection: Requirements for protection against electrical hazards, mechanical hazards, excessive temperatures and hazardous outputs.
• Accuracy of controls & instruments: Tests and tolerances for controls, sensors and output accuracy relevant to oxygen delivery.
• Hazard & fault management: Specifies handling of hazardous situations and fault conditions relevant to patient safety.
• Usability & human factors: Emphasis on usability for lay operators (Clause 206 and usability annexes).
• Gas connections and accessories: Requirements for interfaces, accessories and compatibility (Clauses 201.101–201.103).
• Electromagnetic compatibility (EMC): EMC requirements and test configurations specific to conserving equipment.
• Informative annexes: Rationale, IMDRF & EU MDR cross‑references, terminology and guidance for conformity.

Practical applications - who uses this standard

• Manufacturers and designers of oxygen‑conserving devices (portable bolus delivery, integrated systems with regulators, concentrators or liquid oxygen).
• Regulatory and conformity assessment bodies evaluating safety, performance and labelling for market approval.
• Biomedical engineers and QA teams performing device testing, EMC checks and usability evaluations.
• Clinicians and respiratory therapists who need to understand device operation differences versus continuous flow systems for patient titration.
• Suppliers of accessories (tubing, connectors, regulators) to ensure compatibility and compliance.

Related standards

• IEC/ISO 60601 family (general standard IEC 60601‑1 and relevant collateral standards such as IEC 60601‑1‑2 for EMC and IEC 60601‑1‑6 for usability).
• Cross‑references to IMDRF essential principles and EU MDR requirements are provided in informative annexes.
