ISO 80601-2-70:2015

Overview

ISO 80601-2-70:2015 - Medical electrical equipment - Part 2-70 - sets particular requirements for the basic safety and essential performance of sleep apnoea breathing therapy equipment. It applies to devices that deliver therapeutic breathing pressure (for example CPAP and bi‑level therapies) to alleviate obstructive sleep apnoea (OSA) in patients who are not dependent on mechanical ventilation. The standard covers devices intended for both the home healthcare environment (use by lay operators) and professional healthcare settings. It excludes equipment intended for neonates and devices for patients dependent on mechanical ventilation (e.g., certain central sleep apnoea cases).

Key topics and technical requirements

• Essential performance identification - Defines performance elements that must be maintained for safe therapy delivery.
• Therapy performance tests - Includes test methods for static and dynamic airway pressure accuracy, maximum flowrate and therapy delivery stability.
• Breathing gas pathway & connectors - Requirements and labelling for patient‑connection ports, gas output ports, monitoring probe ports and flow‑direction sensitive components.
• Accessories - Requirements for accessories that can affect safety or performance (labelling, compatibility, humidification and filters).
• Protection & hazards - Electrical, mechanical, thermal and radiation hazard protections, plus CO rebreathing and leakage considerations.
• Alarms, usability and training - Requirements for alarm systems, user information, operating instructions and training for lay and professional users.
• Electromagnetic compatibility (EMC) - Tests and criteria for EMC in home and clinical environments.
• Documentation & marking - Legibility, symbols, warning notices and guidance (Annex C, D).
• Annexes and guidance - Informative annexes cover rationale, data interfaces and references to essential principles for regulators.

Applications and who uses this standard

• Manufacturers of CPAP, bilevel PAP and other sleep apnoea therapy devices - to design and validate safe, compliant equipment.
• Test laboratories and conformity assessment bodies - to perform required safety and performance tests.
• Regulatory and procurement teams - to specify compliance for market approval and purchasing.
• Clinical engineers and biomedical teams - to evaluate device suitability for home or institutional use.
• Accessory designers (masks, tubing, filters, humidifiers) - to ensure compatibility and safety.
