An adapter for use in airway exchange procedure capable of being rapidly coupled and uncoupled to the catheter and being capable of regulating the flow of fluid delivered to the trachea of the patient. Oxygenation is received at the proximal end of the adapter and delivered to a catheter at the distal end. The adapter may include a relief valve to release excess fluid from the provided oxygenation. The adapter may also include a throttling valve to limit the flow of fluid within the valve, preventing excessive pressure or flow rate of breathable fluid to the catheter. During the procedure, the adapter and oxygenation source may be rapidly uncoupled and coupled to the catheter by a connector on the distal end of the adapter.
