What Are The Differences Between Medical Oxygen And Industrial Oxygen?
Medical oxygen is high purity oxygen that is used for medical treatments and is developed for use in the human body. Medical oxygen cylinders contain a high purity of oxygen gas
no other types of gases are allowed in the cylinder to prevent contamination. There are additional requirements and rules for medical oxygen, including requiring a person to have a prescription to order medical oxygen.
Industrial oxygen is focused on uses in industrial plants including combustion oxidation cutting & chemical reactions The industrial oxygen purity levels arent appropriate for human use & there could be impurities from dirty equipment or industrial storage that could harm people.
So as far as i understand the industrial oxygen needs to under further refinement to remove those impurities to make it safe for human use in medical situations. Chemical engineers could explain the processes involved there.
Common Oxygen Misconception
A common belief is that we are breathing 100% oxygen in our atmosphere. That’s not true. The air we breathe is about 21 percent oxygen and 78 percent nitrogen. The last 1% is a mix of other gases like carbon dioxide and hydrogen.
Excellent Doubt
As we learned in school, Earth's Atmospheric air is made up of
Nitrogen 78%
Oxygen 21%
and the remaining 1% made up of other gases
See Pie chart below
So we are breathing this air
We need ONLY 21% right?
Why 99.9% oxygen cylinders then?
This answer is a little long so bear with me. I will try and keep this as simple & brief as possible.
To start with 4 questions...
What is ventilation?
What is oxygenation?
What is respiration?
What is the difference?
Ventilation is a term that refers to the molecular exchange of oxygen and carbon dioxide in the body. Carbon dioxide is transported through the veins to the lungs where it can be exhaled. This natural phenomenon keeps the blood acidity (the pH) down within the normal range.

Let's talk about "evidence" in Evidence Based Medicine #MedTwitter
We have Levels of evidence
Sources regarded as strong evidence include clinical practice guidelines, systematic reviews with meta-analyses, systematic reviews alone, individual randomized controlled trials (RCT)
and well-designed non-randomized control studies. The hierarchy of evidence for treatment questions is based on the notion of causation and the need to control bias.
see figure below
Although each level may contribute to the total body of knowledge, "...not all levels are equally useful for making patient care decisions."
I saw this discussion going on yesterday
Wasn't able to comment for various reasons
There is a lot to unpack here so let's take a step back & look at this objectively & subjectively.
Objectively - the original person is upset because of the way her doctor treated her. She is well within her right to complain & seek alternative options. The person QTing her commented with some friend's comment (hearsay) there by steering the narrative to where she wanted it
Everything else and I mean EVERYTHING else is subjective. If you agree with me till this point then we can carry on. Else I'm afraid you are wasting your time reading on
So let's look at this subjectively. This is where I feel the core of most of the disagreements yesterday were
Classic case of generalizing based on anecdotal evidence
There are Christians who believe they shouldn't eat food which is blessed in another religion & there are those who don't care just like there are Hindus who eat beef & there are Hindus who don't
To each their own🤷♂️
I will never understand this obsession by certain folks about what is on their neighbour's plates. Why does it matter to you? Like seriously i just don't get it.
just as in any religion
you have extremist fanatical followers on one end & liberal laissez faire followers on the other
I have eaten Sabarimala Aravana from colleagues who have climbed up the mountain, and have seen other colleagues who have refused. Why take it personally?
