breathing concentrated oxygen raises tissue oxygen levels up to 20× above baseline
During HBOT, arterial oxygen pressure can reach up to 2000 mmHg and tissue oxygen pressure up to 400 mmHg, increasing the oxygen gradient into tissues by a factor of 20.
What this means for you
When oxygen reaches tissues at much higher concentrations, your cells have more fuel to do their jobs — repairing, energizing, and recovering. Most people associate this with faster bounce-back after physical stress, sharper mental clarity, and a general sense of vitality that comes from cells running at full capacity.
