An<unk>  session consists of an interval of several minutes breathing<unk>  (low oxygen) air, alternated with intervals breathing ambient (normoxic) or hyperoxic air. The procedure may be repeated several times in variable-length sessions per day, depending on a physician's prescription or a manufacturer's protocol. Standard practice is for the patient to remain stationary while breathing<unk>  air via a hand-held mask. The therapy is delivered using a<unk> ator during the day time, allowing the dosage to be monitored. Biofeedback can be delivered using a pulse oximeter.
