Health informatics - Personal health device communication - Part 10421: Device specialization - Peak expiratory flow monitor (peak flow) (ISO 11073-10421:2012)

The scope of this standard is to establish a normative definition of communication between personal telehealth peak flow monitoring devices (agents) and managers (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It leverages work done in other ISO/IEEE 11073 standards including existing terminology, information profiles, application profile standards, and transport standards. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defines a common core of functionality of a peak-flow monitoring device. The use case is restricted to personal respiratory monitoring and therefore does not include hospital-based spirometry. Continuous and high-acuity monitoring (e.g., for emergency response) are outside the scope of the use case. In the context of personal health devices, a peak flow meter is a device used to measure the respiratory function of those managing respiratory conditions such as asthma and chronic obstructive pulmonary disease. The ability to identify declining respiratory status prior to the need for acute intervention improves the quality of life for the individual while reducing the overall costs of care. Respiratory status data are collected by a personal respiratory monitoring device and forwarded to a central data repository for review and action by a health care provider. The data are episodic in nature and are forwarded at designated intervals or when the person is symptomatic.

Dans le contexte de la famille de Normes ISO/IEEE 11073 relatives à la communication de dispositifs, l'ISO/IEEE 11073-10421:2012 établit une définition normative de la communication entre les dispositifs personnels d'analyse de composition corporelle et des gestionnaires (par exemple, des téléphones cellulaires, des ordinateurs personnels, des équipements personnels de santé, des boîtiers décodeurs) d'une manière qui permet une interopérabilité du type prêt à l'emploi. Elle s'appuie sur un travail effectué dans d'autres normes ISO/IEEE 11073, y compris la terminologie, les profils d'informations, les normes de profils d'applications et les normes de transports existants. Elle spécifie l'utilisation de codes, de formats et de comportements en termes spécifiques dans les environnements de télésanté, en limitant les choix à des cadres de travail de base en faveur de l'interopérabilité. Elle définit un noyau commun de fonctionnalités d'un dispositif de surveillance de débit de pointe.

Področje uporabe tega standarda določa normativno opredelitev komunikacije med osebnimi telemedicinskimi napravami za merjenje vršne vrednosti izdihanega zraka in upravljalnimi napravami (npr. mobilnimi telefoni, osebnimi računalniki, osebnimi medicinskimi napravami in digitalnimi sprejemniki) na način, ki omogoča interoperabilnost Plug and Play. Standard temelji na delu, doseženem v drugih standardih ISO/IEEE 11073, vključno z obstoječo terminologijo, informacijskimi profili, standardi za profile aplikacije in standardi za prevoz. Določa uporabo posebnih kod izrazov, formatov in vedenj v telemedicinskih okoljih ter v korist interoperabilnosti omejuje opcionalnost osnovnih okvirov. Ta standard določa skupno jedro funkcionalnosti za napravo za merjenje vršne vrednosti. Primer uporabe je omejen na osebno merjenje izdihanega zraka in zato ne vključuje spirometrije, ki se izvaja v bolnišnici. Trajno merjenje in merjenje v primeru visoke akutnosti (npr. v okviru odziva na izredne razmere) ne spadata na področje uporabe tega primera. Merilnik vršne vrednosti izdihanega zraka se v okviru osebnih medicinskih naprav uporablja za merjenje dihalne funkcije pri ljudeh z boleznimi dihal, kot sta astma in kronična obstruktivna pljučna bolezen. Sposobnost opredelitve slabitve dihanja pred potrebo po akutnemu posredovanju izboljša kakovost življenja posameznika ter niža skupne stroške oskrbe. Osebna naprava za merjenje izdihanega zraka zbira podatke o stanju dihanja in jih posreduje v osrednjo zbirko podatkov, v okviru katere te podatke pregleda izvajalec zdravstvenih storitev in ukrepa v skladu z njimi. Podatki so po naravi občasni in se posredujejo v določenih intervalih ali kadar oseba kaže znake slabitve dihanja.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards
through a consensus development process, approved by the American National Standards Institute, which
brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers
are not necessarily members of the Institute and serve without compensation. While the IEEE administers the
process and establishes rules to promote fairness in the consensus development process, the IEEE does not
independently evaluate, test, or verify the accuracy of any of the information contained in its standards.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is called to the possibility that implementation of this standard may require the use of subject matter
covered by patent rights. By publication of this standard, no position is taken with respect to the existence or
validity of any patent rights in connection therewith. ISO/IEEE is not responsible for identifying essential
patents or patent claims for which a license may be required, for conducting inquiries into the legal validity or
scope of patents or patent claims or determining whether any licensing terms or conditions provided in
connection with submission of a Letter of Assurance or a Patent Statement and Licensing Declaration Form, if
any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly
advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is
entirely their own responsibility. Further information may be obtained from ISO or the IEEE Standards
Association.
ISO/IEEE 11073-10421 was prepared by the IEEE 11073 Standards Comittee of the IEEE Engineering in
Medicine and Biology Society (as IEEE Std 11073-10421-2010). It was adopted by Technical Committee
ISO/TC 215, Health informatics, in parallel with its approval by the ISO member bodies, under the “fast-track
procedure” defined in the Partner Standards Development Organization cooperation agreement between ISO
and IEEE. IEEE is responsible for the maintenance of this document with participation and input from ISO
member bodies.

1 Overview
1.1 Scope
The scope of this standard is to establish a normative definition of communication between personal
telehealth peak flow monitoring devices (agents) and managers (e.g., cell phones, personal computers,
personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It
leverages work done in other ISO/IEEE 11073 standards including existing terminology, information
profiles, application profile standards, and transport standards. It specifies the use of specific term codes,
formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of
interoperability. This standard defines a common core of functionality of a peak-flow monitoring device.
The use case is restricted to personal respiratory monitoring and therefore does not include hospital-based
spirometry. Continuous and high-acuity monitoring (e.g., for emergency response) are outside the scope of
the use case.
In the context of personal health devices, a peak flow meter is a device used to measure the respiratory
function of those managing respiratory conditions such as asthma and chronic obstructive pulmonary
disease. The ability to identify declining respiratory status prior to the need for acute intervention improves
the quality of life for the individual while reducing the overall costs of care. Respiratory status data are
collected by a personal respiratory monitoring device and forwarded to a central data repository for review
and action by a health care provider. The data are episodic in nature and are forwarded at designated
intervals or when the person is symptomatic.

This standard provides the data modeling and its transport shim layer according to IEEE Std 11073-
TM
20601 -2008 and does not specify the measurement method.
1.2 Purpose
This standard addresses a need for an openly defined, independent standard for controlling information
exchange to and from personal health devices (agents) and managers (e.g. cell phones, personal computers,
personal health appliances, set top boxes). Interoperability is key to growing the potential market for these
devices and enabling people to be better informed participants in the management of their health.
1.3 Context
See IEEE Std 11073-20601-2008 for an overview of the environment within which this standard is written.
This standard defines the device specialization for the peak expiratory flow monitor, being a specific agent
type, and it provides a description of the device concepts, its capabilities, and its implementation according
to this standard.
This standard is based on IEEE Std 11073-20601-2008, which in turn draws information from both
1
ISO/IEEE Std 11073-10201:2004 [B2] and ISO/IEEE Std 11073-20101:2004 [B3]. The medical device
encoding rules (MDERs) used within this standard are fully described in IEEE Std 11073-20601-2008.
This standard reproduces relevant portions of the nomenclature found in ISO/IEEE 11073-10101:2004 [B1]
and adds new nomenclature codes for the purposes of this standard. Between this standard and
IEEE Std 11073-20601-2008 all required nomenclature codes for implementation are documented.
NOTE—In this standard, ISO/IEEE P11073-104zz is used to refer to the collection of device specialization
2
standards that utilize IEEE Std 11073-20601-2008, where zz can be any number from 01 to 99, inclusive.
