Abstract

A system and apparatus for utilizing invasive techniques to determine the blood pressure of a patient, are provided. An example system may include a pressure sensor, an intravenous fluid supply bag, and a hollow needle configured to penetrate a blood vessel of a patient. An intravenous supply tube may fluidly connect the pressure sensor to the hollow needle. A lumen filled with an incompressible fluid may be disposed within the intravenous supply tube. The lumen may be coupled to the pressure sensor at one end and terminate in a flexible membrane at the other end. The flexible membrane may deform in response to a blood pressure wave transmitted from the blood vessel of the patient, and transmit the blood pressure wave through the incompressible fluid and to the pressure sensor. The pressure sensor may determine a blood pressure measurement based at least in part on the received blood pressure wave.
