An oxygen tube often gets caught under a chair leg or wheelchair wheel, and air stops flowing when it kinks. The AirLife nasal cannula uses a 2.1 m crush-resistant tube that keeps its passage open even under point pressure. Its curved tips follow the natural direction of the nostrils for a more stable support.

• The tubing goes around the ears and down under the chin, with no strap to go behind the head
• The 2.1 m length allows enough slack to move around a room without disconnecting the source
