I googled again.
If we're talking about the amount of pure oxygen in a scuba diving tank, rather than (as is most likely) the amount of 'breathing material' a scuba diving tank contains:

Scuba diving tanks use 20.9% oxygen.
Round it up to 21% - that's 302.4 litres of pure oxygen.

Here's a 500 litre liquid oxygen container - the sort used for covid patients, for perspective:

I doubt if the doctor was advocating using the same sort of oxygen but was trying to find a way of explaining the vast amount needed for one person.

I think the measure/ metering of free oxygen is different from scuba diving gases, in any case pure oxygen in a scuba environment is lethal

I wonder how much that's costing us financially ........ :-(

It appears, 90% of those now in hospital with covid are unvaccinated - some because they were too young - the majority (including the user Nameslessone mentions), because they're 'anti-vaccers', or believe it won't happen to them.

Wow!


No wonder hospitals were running low during the worst of the epidemic. It really puts things in perspective.

I had to 'Google'.
40 hours is 2,400 minutes.
Apparently a 3 litre scuba tank(on your back, size) would last 10 minutes above ground, and 5 minutes if you were 10metres under water.
So, (I think) you'd need 480 of those 3 litre tanks to last 40 hours underwater
That's 1,440 litres.

I sometimes think that not enough fuss is made about some COVID updates.
Such as what is happening to Israel at the moment.

This was in today’s Daily Mail. A large man, unvaccinated, was on oxygen. The doctor writing the article said to imagine a scuba tank capable of keeping you under water for 40 hours. The patient got through it in 15 minutes.
Stunning.
