This document establishes a vocabulary of terms and semantics for all fields of respiratory care involving mechanical ventilation, such as intensive-care ventilation, anaesthesia ventilation, emergency and transport ventilation and home-care ventilation, including sleep-apnoea breathing-therapy equipment. It is applicable — in lung ventilator and breathing-therapy device standards, — in health informatics standards, — for labelling on medical electrical equipment and medical electrical systems, — in medical electrical equipment and medical electrical system instructions for use and accompanying documents, — for medical electrical equipment and medical electrical systems interoperability, and — in electronic health records. This document is also applicable to those accessories intended by their manufacturer to be connected to a ventilator breathing system or to a ventilator, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilator and ventilator breathing system. NOTE This document can also be used for other applications relating to lung ventilation, including non-electrical devices and equipment, research, description of critical events, forensic analysis and adverse event (vigilance) reporting systems. This document does not specify terms specific to breathing-therapy equipment, or to physiologic closed-loop ventilation, high-frequency ventilation or negative-pressure ventilation; nor to respiratory support using liquid ventilation or extra-corporeal gas exchange, or oxygen, except where it has been considered necessary to establish boundaries between bordering concepts.

This document specifies the general requirements for sampling, preservation, handling, transport and storage of all water samples for physicochemical, chemical, hydrobiological and microbiological analyses and determination of radiochemical analytes and activities. Guidance on the validation of storage times of water samples is provided in ISO/TS 5667-25.

This document specifies a means for communicating part or all of the electronic health record (EHR) of one or more identified subjects of care between EHR systems, or between EHR systems and a centralised EHR data repository. It can also be used for EHR communication between an EHR system or repository and clinical applications or middleware components (such as decision support components), or personal health applications and devices, that need to access or provide EHR data, or as the representation of EHR data within a distributed (federated) record system. This document will predominantly be used to support the direct care given to identifiable individuals or self-care by individuals themselves, or to support population monitoring systems such as disease registries and public health surveillance. Uses of health records for other purposes such as teaching, clinical audit, administration and reporting, service management, research and epidemiology, which often require anonymization or aggregation of individual records, are not the focus of this document but such secondary uses might also find the document useful. This Part 1 of the multipart series is an Information Viewpoint specification as defined by the Open Distributed Processing ? Reference model: Overview (ISO/IEC 10746-1). This document is not intended to specify the internal architecture or database design of EHR systems.

This document outlines a core dataset designed for a concise dental data exchange intended to support continuity and coordination of care. It provides a conceptual framework for a dental data for exchange that can serve as the basis for implementation models. The content reflects an international perspective on organizing dental information for cross-border exchange. It offers guidance on the essential data elements that should be shared globally and proposes a standardized format for their representation. The document focuses on defining the structure of the data to be exchanged (“the what”) without prescribing the specific methods or technologies used for transmission (“the how”). It does not include guidance on operational workflows such as data entry, collection, summarization, or integration. Nor does it address the competencies required to perform those tasks. Furthermore, it is not intended as an implementation guide and does not cover the underlying technical infrastructure or the use of particular coding systems, data formats, or terminologies.

Within the context of the ISO/IEEE 11073 family of standards for device communication, a normative definition of the communication between personal basic electrocardiograph (ECG) devices and managers (e.g. cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability is established in ISO/IEEE11073-10406:2012. Appropriate portions of existing standards including ISO/IEEE 11073 terminology and IEEE 11073-20601 information models are leveraged. The use of specific term codes, formats and behaviours in telehealth environments restricting optionality in base frameworks in favour of interoperability is specified. A common core of communication functionality for personal telehealth basic ECG (1- to 3-lead ECG) devices is defined. Monitoring ECG devices are distinguished from diagnostic ECG equipment with respect to support for wearable ECG devices, limiting the number of leads supported by the equipment to three, and not requiring the capability of annotating or analysing the detected electrical activity to determine known cardiac phenomena. ISO/IEEE 11073-10406:2012 is consistent with the base framework and allows multifunction implementations by following multiple device specializations (e.g. ECG and respiration rate).
