Most of us would imaging a scuba diver if we were to mention anything about portable oxygen tanks but there are many other uses for these devices that you will find interesting. You may find a portable oxygen tank in an ambulance ready for people off the street that are having trouble breathing. Fire fighters also use these oxygen tanks when they get right into a building that is full of smoke and fire. They also use them after the fire if any of the fighters have got smoke inhalation.
Nursing homes and retirement villages that have doctor’s surgeries on them also are common places that you will find portable oxygen tanks. In these type of environments where there are many elderly people around you will expect that some of them are going to have beathing problems which can be sorted out using the oxygen tanks.
