The subject matter described herein includes an assembly having a syringe, a pressure gauge, and an adapter. The adapter defines a longitudinal pathway that allows for flow through of fluids from a first terminal inlet to a second terminal outlet. The adapter also defines a second pathway that allows for flow through of fluids from a third terminal inlet into the longitudinal pathway. The first terminal inlet defines a threaded portion that selectively engages the syringe. The adapter defines a knurled grip that facilitates stabilization of the adapter when engaged with the syringe. The second terminal outlet selectively engages a tube that carries an inflatable balloon on an end thereof. The balloon is configured for sealing a patient's trachea when inflated. The third terminal inlet selectively engages the pressure gauge.
