Abstract
Oxygen-delivery systems are described. The systems may supply emergency respiratory gas on demand to aircraft passengers. To reduce risk of blockage of tubes delivering anti-blocking gas to the face masks worn by the passengers, the systems may be designed to provide a continuous trickle flow of respiratory gas, or one or more anti-blocking pulses of gas, into a delivery tube.
