I saw in the news today that hospitals had to put patients on oxygen therapy and hoped for the best because they did not have enough ventilators.

What you have there wouldn't even work as oxygen therapy unless a person stood there regularly replacing canisters. Also, how do you adjust that thing? How much oxygen is the patient getting?

Starting at eight-years-old, I had to help my grandmother, who was on oxygen therapy, which is how I learned about oxygen systems.
