O2 is supplied from (typically) BOC in liquid form; when required, allowed to evaporate into gas, & supplied to hospital outlets.
Most hospitals have a VIE big enough to meet their needs

I’m going to tag this as a little tutorial for @MichaelYeadon3 who keeps saying that there’s no problem from the suppliers of medical ‘gasses’
Most hospitals in the U.K. run their O2 supply from a Vacuum Insulated Evaporator (VIE)

Most ~12 bed ICUs have pipes that allow ~400L/min flow
This is Ok because most ventilators don’t use >20l/min; giving useful buffer capacity
Modern non invasive ventilation systems- CPAP, NIV, and High flow nasal Oxygen (HFNO), however, need more
3/n
6 of these patients will come very close to triggering the O2 flow alarm for this 12 bed unit.

5/n
A typical F cylinder has 1360 litres Oxygen. And weighs 18KG.
That will last ~22 minutes for a patient on HFNO
That’s 72 cylinders per patient per day.
That’s not how you can run a service.
6/n
These 72 cylinders cost approx £2000. That’s ~20x more than liquid O2 in a VIE.
Typical ICU tariff for a L2 patient is <£1500!

Leads to problems with staffing and cover for safety

The problem is infrastructure and old estate.
Please stop this misinformation.

You gotta think about this one carefully!
Imagine you go to the doctor and get tested for a rare disease (only 1 in 10,000 people get it.)
The test is 99% effective in detecting both sick and healthy people.
Your test comes back positive.
Are you really sick? Explain below 👇
The most complete answer from every reply so far is from Dr. Lena. Thanks for taking the time and going through
You can get the answer using Bayes' theorem, but let's try to come up with it in a different —maybe more intuitive— way.
👇
Here is what we know:
- Out of 10,000 people, 1 is sick
- Out of 100 sick people, 99 test positive
- Out of 100 healthy people, 99 test negative
Assuming 1 million people take the test (including you):
- 100 of them are sick
- 999,900 of them are healthy
👇
Let's now test both groups, starting with the 100 people sick:
▫️ 99 of them will be diagnosed (correctly) as sick (99%)
▫️ 1 of them is going to be diagnosed (incorrectly) as healthy (1%)

This is the $1mln question still without an answer: why were these workers cleaning bat guano from that abandoned mine?
Surprisingly we simply don't know.
China would have all interest in clarifying that point if for instance they were prospecting or selling guano. It did not.
What we know is that EcoHealth + WIV were sampling bat sites in the vicinity at the exact time of the workers being in that mine.
#DRASTIC wrote about this and about other oddities in the official story:
Maybe it's just one of these coincidences.
Then it gets interesting: about a year after the miners death, Olival & Epstein from EcoHealth Alliance co-authored a paper about the coronavirus risk infection from bat guano collection.
No mention of the
That paper oddly used some old bat samples collected by DARPA in 2006/7 at the famous Thai bat cave.
It never mentioned that the Thai monks have been doing this every Sunday for many many years without infection.
But most interestingly it never mentioned the Mojiang mine accident, even if the perfect timing and recycling of old DARPA bat samples seem to point to a likely knowledge of it.
Anyway, the idea was to ask for more money, as you correctly

The miners were tasked with removing bat feces. AFAIK it hasn't been established why they were doing this. Given that EcoHealth was collecting bat fecal samples in the same province around the same time, is it possible these miners were actually collecting guano for EcoHealth?
