    • A method for performing an in-vivo calibration of a blood pressure sensor (40) that is associated with a balloon (10) of an in-vivo balloon system, the sensor and balloon being associated such that the sensor is in-vivo when the balloon is in-vivo. The balloon is inflated so that a gas pressure in the balloon system is indicative of a patient's blood pressure. The patient's blood pressure is monitored through two channels, the gas pressure and the sensor. The blood pressure measurements obtained by monitoring the gas pressure are used as reference, or "true," blood pressure measurements to determine a mathematical relationship between blood pressure measurements obtained through the sensor and the reference blood pressure measurements. In this manner, future blood pressure measurements obtained through the sensor can be modified according to the mathematical relationship to generate calibrated blood pressure measurements.
    • 一种用于执行与体内球囊系统的球囊(10)相关联的血压传感器(40)的体内校准的方法,所述传感器和球囊相关联,使得所述传感器在 气球在体内。 球囊充气使得球囊系统中的气体压力指示患者的血压。 通过两个通道监测患者的血压,即气体压力和传感器。 通过监测气体压力获得的血压测量结果被用作参考或“真实的”血压测量结果以确定通过传感器获得的血压测量结果与参考血压测量结果之间的数学关系。 以这种方式,可以根据数学关系修改通过传感器获得的未来血压测量结果,以生成校准的血压测量结果。
