Overview
ISO/IEEE 11073-10421:2012 - "Health informatics - Personal health device communication - Part 10421: Device specialization - Peak expiratory flow monitor (peak flow)" defines a normative, interoperable communication profile for personal telehealth peak expiratory flow (PEF) monitors and manager devices (e.g., smartphones, PCs, set‑top boxes). Part of the ISO/IEEE 11073 family, this standard specifies the data modeling and transport shim layer (per IEEE 11073-20601) to enable plug‑and‑play device communication in telehealth environments. It focuses on personal respiratory monitoring (asthma/COPD self‑management) and explicitly excludes hospital spirometry and high‑acuity continuous monitoring.
Key Technical Topics and Requirements
- Normative communication definition between agent (peak flow monitor) and manager (mobile apps, gateways) to ensure interoperability.
- Data modeling using ISO/IEEE 11073 information models and medical device encoding rules (MDER) as defined in IEEE 11073-20601.
- Restricted optionality: prescriptive use of term codes, formats, and behaviors to reduce ambiguity and improve cross‑vendor compatibility.
- Device specialization constructs: domain information model classes (numeric objects, real‑time sample arrays, enumerations, PM‑store, scanners, and class extensions).
- Service and communication models: association, configuration, operation procedures, time synchronization, and object access/event report services.
- Conformance and testing: sections on test associations, levels of conformance, and implementation conformance statements to support validation.
- Supporting annexes: ASN.1 definitions, identifier allocation, example message sequences, and protocol data unit samples to aid implementers.
Practical Applications
- Enables manufacturers to build plug‑and‑play peak flow meters that reliably exchange PEF data with smartphones, home gateways, and cloud repositories.
- Supports mobile health (mHealth) apps and personal health records that aggregate episodic respiratory data for patient self‑management and clinician review.
- Facilitates integration of consumer respiratory devices into telehealth platforms, remote monitoring services, and chronic disease management workflows.
- Reduces integration time and costs by specifying standardized nomenclature and transport layers for device‑to‑manager communication.
Who Would Use This Standard
- Device manufacturers and firmware developers for peak flow meters
- mHealth and health‑IT application developers
- System integrators and telehealth platform vendors
- Test labs and certification bodies verifying interoperability and conformance
- Procurement and regulatory stakeholders assessing device communication capabilities
Related Standards
- ISO/IEEE 11073-20601 (application profile / optimized exchange protocol)
- ISO/IEEE 11073-10101 (nomenclature) and 11073-10201/20101 (information model foundations)
- Other 11073 device specializations (e.g., pulse oximeter, blood pressure monitor)
By conforming to ISO/IEEE 11073-10421, stakeholders can achieve consistent, interoperable peak flow data exchange across consumer devices and telehealth ecosystems.
