From: Unconventional approaches to mechanical ventilation—step-by-step through the COVID-19 crisis
Although intensive care ventilators represent the standard of care, anesthesia ventilators can be used without difficulty if their conceptual differences are accounted for (e.g., the presence of trained personnel). Modern transport ventilators, albeit comparable in performance, can only be used for bridging as they are supplied by ambient air. Unconventional methods such as ventilator splitting should be treated with great caution and are only justified if all other resources are exhausted
