Purging your reg is not gonna solve the issue. Think about it:
The human body has no way to determine the amount of oxygen present in the blood. But, we have a little sensor in the back of our brain that can measure the carbondioxide level in the blood.
CO2 level too high? -> signal the brain that the breathing has to increase.
And that's the feeling which you experience as not getting enough air.
The exact process of gas exchange in your lungs can be explained with partial gas pressures as it's all physics laws, but the whole point is still simple:
- you breathe in air.
- your body uses the oxygen in that air, it goes from your lungs into your blood.
- after using the oxygen in your body, carbondioxide is transported back to your lungs.
- CO2 can go from your blood to your lungs if the amount of CO2 in your lungs is low.
- you breathe out the CO2.
