dear students or whoever anaphysio maybe confusing but to be very honest, in real practice u will understand it, u will learn to connect things once u encounter real patient during clinicals.. good luck

Also worth mentioning adjusting for FiO2 when interpreting PaO2. Very roughly, a normal PaO2 is FiO2 - 10. So if FiO2 is 80%, then a so-called "normal" PaO2 is actually profoundly hypoxic.

[@ZeroToFinals]

Good point!

[@championssportsagency3540]

When you run a ABG, you will have to enter FIo2 and temperature so your results are taking those in consideration

Thanks, a great video. Additionally, a method of assessing appropriate oxygenation is 5×FiO2, if PaO2 is below that means imapired oxygenation

This is a very informative data. However, I do have a question. What would indicate an underline of a medical problem if your blood work shows a low level of "pO2 (v) POC" at 25 mmHg in ref. to the average between 80 - 105 mmHg? Symptoms are shortness of breath, weakness in body upon exertion. Resting seems help. Thank you! BTW, do we need this test as well?

My step son is in ICU on a ventilator & ECMO machine. He has Covid & a severe bacterial pneumonia. Psuedomonis and Klebsiella. He's pretty sick. His lungs are full of clots. They did a bronchoscopy & found his chest tube has punctured his airway. He's a mess. I feel so helpless.

so sorry to hear that. it does feel helpless but just being there is what goes a very long way. how is he doing now?

Water plus salt ions are loaded into the passing RBCs
Surfactant creates a bubble over the neck
The bubble bursts and sprays water/salt onto the capillaries
And RBCs absorb
Lungs are regulating hydration
RBCs dark and collapsed are dehydrated
RBCs bright and full are hydrated
Breath pH is measured turning lime water cloudy not CO2
pH is determined by the salt component of the respiratory aerosols
Mucosa regulates the ion/salt content and the moisture inside the airways
Adding on the in breath
Subtracting on the out breath
Moisture at the alveoli will contain salt concentration at 0.9% isotonic to RBCs.
At the alveoli the humidity must reach 100%
That’s water droplets
The surfactant creates a bubble which bursts and jets the moisture droplets onto the capillaries
RBCs rehydrate
Excess drains to the lymph
Lungs work harder where?
Altitude and the cold why?
Altitude has reduced pressure
Cold air holds the least moisture
Mountaineers are dying on their mountains from acute oxygen toxicity which is more lethal with fatigue, cold and dehydration.
Wim hoff method increases pressure it’s a hyperbaric technique
Allowing a novice to breath hold 2.5min
No oxygen
No carbon dioxide
We breath air the gas form of water
Air is measured by its water content, humidity
Oxygen toxicity is due to its power to dehydrate
Medical oxygen has 67ppm of water contamination
See it’s measured by water content
Oxygen is a product and manufactured not present in air naturally
Oxygen was made to solve a problem in metallurgy
Water decomposes
They needed a dry air to infuse into the metal matrices so the water content didn’t decompose or corrode the compound
Yes every metal is a compound
Industrial oxygen has 0.5ppm of water contamination
It’s made by heating to dry and compression for efficiency
On repeat until the desired dryness (water contamination) is reached
Nitrogen is also a product
Made by taking oxygen and adding carbon particles to stop the flammability enhancement
So metals being shaped can be infused with a dry air that doesn’t cause fires with sparks
Eg wire pulling
Water is an element

100 reasons water is not H2O
By Peter Peterson
Smashwords
Free eBook
Water can be distilled because it doesn’t react with compounds, it acts as a carrier of ions, the medium and therefore is never lost to us and can cycle
It’s the great decomposer

[@janethrees9907]

They fool you by telling you these manufactured gases are in the atmosphere
Just need to look at the processes they use to “extract” them to see it’s not an extraction process
Look up patents for oxygen and nitrogen production
Eg Carbon filters that give required concentrations of carbon to nitrogen
