1. A respiratory assistance component comprising:

  • a first conduit and a second conduit that are both configured to supply breathable gas to a patient, each one of the first and second conduits comprising electro active polymer that causes the respective conduit to change shape and/or size between a first non-energized state, when no electrical voltage or current is applied to the electro active polymer, and a second energized state, when voltage or current is applied to the electro active polymer, wherein the electro active polymer of the first conduit and the electro active polymer of the second conduit are configured to be selectively energized by a power source that is controlled by a controller,wherein a flow of the supplied breathable gas that is supplied to the patient through at least one of the first and second conduits is measured and flow data is provided to the controller, which determines when a reduction in flow occurs in one of the first and second conduits based on the measured flow data and, in response to the determination, causes the power source to selectively energize at least one of the first and second conduits so as to modify or maintain an aspect of the respiratory assistance provided to the patient.
