Ventilator Operational Configuration 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 4 (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, as well as a mapping to any "glossary" developed within ISO TC121/SC4.
Operational Configuration Data Set
Given the complexity and versatility of how a ventilator is configurated, mapping all the operational settings concepts into a single term or semantic model is a fairly intractable proposition. To address this complexity, a set of parameters has been proposed to convey how a device's operation has been configured.
Atrribute | Description | Enumerations |
---|---|---|
Patient Interface | Indicates the general mechanical connection between the patient and the ventilator. |
|
Delivery Method | Overall approach for achieving gas delivery.
Note: This mode setting may end up selecting a different set of "operational mode" enumerations. Those listed below are specifically related to Positive Pressure delivery method, which is used for conventional mechanical ventilation. |
|
Operational Mode | General intra- and inter- breath sequencing. | |
Backup Mode | Mode that is actived when an apnea condition is detected. |
Operational Mode Attributes (Positive Pressure)
For conventional "positive pressure" mechanical ventilation, the following table captures the key attributes that may be used to describe its operational mode.
Note: These attributes are listed in the preferred sequential precedence.
Atrribute | Description | Discussion |
---|---|---|
Breathing Pattern | <general semantic attribute description>
|
... |
Breath Shape | <general semantic attribute description>
|
|
Adaptive Targets | <general semantic attribute description>
|
|
Assist Augmentation | <general semantic attribute description>
|
Note: During the 2008-05-15 WebEx it was decided to add another Attribute to this table - "Assist/Support Breath Augmentation" (final name TBD). |

Mode Issues / Action Items List
The following table captures the current issues that need to be resolved regarding the above model:
Item Submitters Attr Topic Description Discussion/Disposition 1 Berryhill Breath Shape PF or is it really PV? Mark wanted to know if the BREATH SHAPE item should be classified as Pressure-Flow or Pressure-Volume. In his opinion, in a volume assured breath, you set the pressure, then maintain a flow until you reach the assured volume-Joel . 2 tbd . . . .
Mode Mapping Sandboxes
The table below may be used to try out mapping specific vent modes (real modes provided on real vents!) and to discuss issues with the model above - gaps, adjustments, etc.
NOTE: A sample table has been provided - copy that heading and table and then use it as a sandbox for your own mappings.
