Within the context of the ISO/IEEE 11073 family of standards for device communication@ this standard establishes a normative definition of communication between personal telehealth blood pressure monitor devices and compute engines (e.g.@ cell phones@ personal computers@ personal health appliances@ and set top boxes) in a manner that enables plug-and-play interoperability. It leverages appropriate portions of existing standards including ISO/IEEE 11073 terminology@ information models@ 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 communication functionality for personal telehealth blood pressure monitors.
