1. An electrocardiogram (ECG) electrode application system, comprising:
an electrode distributor, comprising:
a housing; and
a suction manifold assembly disposed within the housing, wherein the suction manifold assembly comprises a manifold, a plurality of pneumatic valves integrated within the manifold, and the manifold comprises a common manifold chamber fluidly coupled to each pneumatic valve of the plurality of pneumatic valves, and each pneumatic valve comprises a venturi passage, wherein each pneumatic valve comprises a valve body portion coupled to an inlet portion, and each pneumatic valve comprises an outlet portion and a narrow portion disposed between the valve body portion and the outlet portion, and wherein the narrow portion has a diameter that is less than a respective diameter of each of the inlet portion, the valve body portion, and the outlet portion; and
a plurality of suction electrodes, each suction electrode of the plurality of suction electrodes having an electrode suction dome and coupled to the electrode distributor via a lead wire, and each lead wire is coupled to a respective pneumatic valve;
wherein each electrode suction dome is configured, when pressed to cause a change in air pressure that results in a suction pressure being applied within a respective electrode suction dome, to adhere a corresponding suction electrode to a subject at a pressure determined by the venturi passage of a corresponding pneumatic valve.
