Abstract:
1. An interface configured to connect between a noninvasive blood pressure (NIBP) sensor and an invasive blood pressure (IBP) monitor comprising: a first input configured to receive a measurement signal indicative of a NIBP of a subject from said NIBP sensor; a second input configured to receive a transducer excitation signal provided by said IBP monitor; at least one processor(s) configured to receive said measurement signal and said excitation signal and emulate an output signal indicative of an IBP of said subject according to predetermined instructions; and an output configured to provide said output signal in a form suitable for input to said IBP monitor; wherein said processor(s) is further configured to supply a zeroing signal to said output when calibration of said measurement signal is in progress or when said measurement signal is distorted.
