Thus, we will not be held responsible for any damages, liability that result from utilization of this document within other contexts.

Healthcare systems around the world now face an unprecedented challenge with the COVID-19 pandemic. Best case scenario, in your healthcare system you will not need this. So we are keeping our fingers crossed that this project is not used. But in the case that your system is already at capacity, we sincerely hope that this project might help bring care to more people who are critically ill.
