1. A method of operating an aspirator arrangement, the method comprising: exerting a first force on a plunger of an aspirator air vent valve of the aspirator to direct the plunger towards a proximal inner wall of the aspirator air vent valve; engaging the plunger with the proximal inner wall of the aspirator air vent valve with the first force; and directing a fluid from a compressed fluid source through an air vent valve air channel defined by the aspirator air vent valve, through the aspirator, and into an inflatable evacuation device; wherein the first force moves the plunger from a first position to a second position; a vent passage extending between and to the proximal inner wall and an outer wall of the aspirator air vent valve is in fluid communication with the air vent valve air channel when the plunger is in the first position; and the vent passage is sealed from the air vent valve air channel by a sealing gasket coupled to a proximal side of a head of the plunger when the plunger is in the second position.
