An integrated pressure sensing device is disclosed. Embodiments of the disclosed concepts provide a device that integrates hemodynamic pressure transducers or sensors into a single package. The package can be designed for precordial placement on the subject so that pressure readings are substantially accurate and appropriately calibrated without “leveling” the sensors relative to a subject's heart using a separate support, and regardless of the subject's position. A lumen set can be configured to maintain a fluid column between each pressure transducer and the subject's blood stream and in some embodiments, the assembly, including all transducers, can be fed from a single fluid source such as a single IV bag.
