As people have come forward in the internet and social media to form a intricate network among those who serve oxygen and those who need it, we felt that disjoint posts are sometimes confusing, and a complete database can help us more in emergency.

Finally, this is a completely non-profit initiative, that arose from our duty towards the society we live in.
