Abstract
A tracheotomy tube comprises a first port for orienting outside the neck of a wearer, a second port for orienting within the trachea of the wearer, and a passageway connecting the first and second ports to permit the flow of gases from the first port to the second port on inhalation by the wearer and from the second port to the first port on exhalation by the wearer. The tracheotomy tube further comprises a third port oriented between the first and second ports, and a valve controlling flow through the third port. The valve opens to permit flow from the passageway through the third port.
