Oxygen therapy involves administering oxygen at a concentration which is higher than that found in air, in order to treat or prevent symptoms and onset of arterial hypoxemia.

Breathing is the set of processes which allow air to go in and out of our lungs, enabling us to assimilate oxygen from the atmosphere and expel carbon dioxide produced by cell metabolism.

Sleep-related respiratory disorders are a common occurrence. They vary from ordinary snoring to the complete or partial interruption of breathing, respectively called apnea and nocturnal hypopnea.

The term ‘Telemedicine’ covers technological solutions which harness electronic and digitalcomputerised systems to send information between doctors and patients, or between professionals, thereby reducing the need for patients to travel to a minimum.
