Use of nasal reservoir cannula
Top panel: During exhalation, the membrane in the Oxymizer reservoir cannula is thrust forward, creating a 20 mL chamber. Bottom panel: When the patient is ready to inhale, he/she receives the stored oxygen in addition to the supply oxygen. This allows the patient to become adequately oxygenated at lower supply flows.
