Leak increases did not modify the AI for ICU-like ETV, while it influenced efficiency for three sophisticated ETV.
ICU-like ETV are devices that, even if transportable, cannot be considered for transportation on a routine basis; sophisticated ETV usually depict curve monitoring screens and allow noninvasive ventilation; simple ETV are standard devices providing no extensive monitoring; mass-casualty/military ETV are devices dedicated for field operations.
When comparing the same experimental conditions, results of ICU-like ETV do fall within range.
For all ICU-like ETV except one, the NIV mode enabled an AI decrease <10%.
To our knowledge, no guideline exists for standard ETV, but except for ICU-like ETV, two out of three devices had battery duration ≥4 hours.
Major differences were observed in terms of weight and volume, and ICU-like ETV seemed dedicated to use within ICUs and/or for intra-hospital transportation of severely ill patients, but not for standard out-of-hospital transport.
No significant difference was observed while comparing ICU-like ETV triggering performances to sophisticated and simple ones (198 ± 80 versus 256 ± 84 versus 422 ± 206 ms respectively; P = 0.18).
The few post-18 and post-21 supports, like ETVs, need to be greatly expanded.
Our simulation model confirms that most new generation ICU-like and sophisticated ETV induces low effort to trigger, while simple ETV (even the most recent devices that are presumed to enable CPAP), were not adequate for such a purpose.
Its clients include companies like CNBC, Express News, ESPN Star, ETV, MediaCorp and NDTV.
Applied PEEP was adequate for most devices in the ICU-like and sophisticated ETV categories, without impact of respiratory mechanics.
