A pressure transducer assembly comprises a pressure transducer, a cable, an expandable member, and a vented connector. The cable includes a proximal end, a distal end, and a vent tube. The proximal end is operatively connected to the pressure transducer. The expandable member is operatively connected to the vent tube proximate the distal end. The vented connector is operatively connected to the distal end, and the vented connector is configured and arranged to allow exposure of the vent tube to atmospheric conditions when in a disconnected configuration and to prevent exposure of the vent tube to atmospheric conditions when in a connected configuration. The expandable member accommodates changes in air pressure within the vent tube when the vented connector is in the connected configuration.
