The pressure is the magic. It’s the pressure that pushes the oxygen into the part of the bloodstream where it never goes when you simply breathe it in. That is the plasma and the plasma is what takes the oxygen past blockages and allows it to penetrate to the injured areas to help rebuild and restore tissue and regenerate cell health and vigor. When you use an oxygen concentrator you are simply adding more oxygen to the hemoglobin which already has almost full capacity.
