Inspiratory and expiratory limbs (connected to the Neonatal swivel Y-piece) rotate 360° and independently of each other. At a right angle to these connections, the tracheal tube (catheter) connection rotates 360°.
Both of these limbs can be disconnected (from the Y-piece) to facilitate adaption for non-invasive therapies such as nCPAP and nHFOT.
