Abstract
In oxygen therapy, the patient is provided a mixture of air and oxygen. In the process, the oxygen is led from an oxygen supply container or an oxygen concentrator through a tube to the patient and made available for inhalation. The distribution system includes a whirler with openings directed toward the patient's mouth and nose. The oxygen flow is twisted into a spiral shape inside the whirler before it exits from the openings.
