So if you require 3 liters per minute of oxygen, that amount of oxygen is delivered to you throughout one minute whether you take 20 breaths each minute or 10. Continuous flow oxygen concentrators deliver a set amount of oxygen per minute when set to the corresponding setting.
Oxygen Saturation. Normally, as PaO2 rises, SaO2, or oxygen saturation, will rise as well. Oxygen saturation of arterial blood has a normal range of 94%-100%. What this means is that normally 94%-100% of oxygen binding sites (which are located on hemoglobin) are saturated with oxygen. Note how that neither PaO2 nor oxygen saturation tell you how much total oxygen is in the blood. Another way to view oxygen saturation is to think about how sponges work.
