EN ISO/IEEE 11073-10421:2026 PDF

Overview

EN ISO/IEEE 11073-10421:2026 is a harmonized European standard developed by CEN, aligning with ISO and IEEE, which specifies requirements for interoperable communication between personal health peak expiratory flow monitors (commonly known as peak flow meters) and computing devices acting as managers (such as smartphones, PCs, or health appliances). This standard addresses device interoperability in health informatics by providing a uniform framework to ensure that data from peak flow monitors is reliably transferred and understood across different telehealth platforms and software, promoting "plug-and-play" compatibility.

This standard is designed specifically for personal peak expiratory flow measurements, focusing on home or community settings for monitoring chronic respiratory conditions like asthma and COPD. It does not cover clinical spirometry or acute-care/high acuity monitoring scenarios.

Key Topics

• Device Interoperability: The standard establishes a normative structure for how peak flow monitoring devices (agents) exchange data with managers (receivers) in telehealth environments, ensuring seamless integration regardless of device manufacturers.
• Data Communication Protocols: It specifies the use of consistent term codes, information models, data formats, and prescribed behaviors. This harmonization reduces optionality and ambiguity, supporting reliable data exchange.
• Core Functionality: EN ISO/IEEE 11073-10421 outlines a common core set of device capabilities and expected communication features, helping manufacturers create compliant and secure peak flow meters.
• Use of Existing Standards: The document builds on foundational work from related ISO/IEEE 11073 standards, leveraging established terminology, application profiles, and interoperable frameworks for personal health devices.
• Personal Respiratory Monitoring: Emphasis is placed on capturing episodic peak flow data for the ongoing management of conditions such as asthma and COPD, aiding in early identification of declining respiratory status and supporting preventative care.

Applications

• Home Health Monitoring: Enables patients to record peak expiratory flow measurements with consumer devices, which can then automatically share results with healthcare practitioners for review.
• Remote Patient Management: Facilitates efficient transfer of respiratory data from patients to care teams, supporting proactive chronic disease management and reducing emergency interventions.
• Health Data Integration: Provides a standardized protocol for device manufacturers and telehealth software vendors, simplifying integration of peak flow data into broader electronic health records (EHR) and personal health applications.
• Quality of Care Improvement: By ensuring interoperability, healthcare providers can access accurate and timely peak flow data, allowing for data-driven decisions and reducing the need for hospital visits.
• Cost Reduction: Early identification of respiratory decline via interoperable peak flow meters helps prevent acute episodes, contributing to lower healthcare costs.
