PCD RTM Vent Modes

Ventilator Operational Mode Semantic Model

A key item in the Vent TG's discussion is to identify the core semantic components that make up a ventilator's operational modality. This in turn can be used to organize a device's settings, waveform annotations, etc. It is understood that the actual labels associated to a given mode will vary from vendor's device to device, and should eventually be harmonized with related activities such as the work being done within ISO TC121/SC 3/JWG 1 (Joint with IEC/SC62D) Critical Care Ventilators. Component semantics should be flexible enough to support all of these usages, though.

Note: This is also intended to result in an update to the existing ventilator operational modality terminology standard contained in ISO/IEEE 11073-10101 Health informatics - Point-of-care medical device communication - Nomenclature document.

The following table illustrates the current model being proposed:

Ventilatator Operational Mode Attributes

Atrribute	Description	Discussion
Patient Interface	<general semantic attribute description> Option(IV-Invasive): Option(NIV-Non-Invasive):	...
Delivery Method	<general semantic attribute description> Option(TBD-...):	...
Breathing Pattern	<general semantic attribute description> Option(TBD-...):	...
Breath Shape	<general semantic attribute description> Option(TBD-...):	...
Adaptive Targets	<general semantic attribute description> Option(TBD-...):	...
Assist Augmentation	<general semantic attribute description> Option(TBD-...):	Note: During the 2008-05-15 WebEx it was decided to add another Attribute to this table - "Assist/Support Breath Augmentation" (final name TBD).
