The concentration of oxygen inhaled during oxygen therapy depends on the flow rate of oxygen being delivered and the delivery method used (e.g., nasal cannula, mask). Higher flow rates or different delivery methods can increase the concentration of oxygen being delivered to the patient.
Inhaled oxygen diffuses through the walls of the alveoli in the lungs, then into the bloodstream where it binds to hemoglobin in red blood cells for transportation to tissues and cells in the body.
