Abstract
An arterial line emulator interfaces a non-invasive blood pressure monitor with an invasive blood pressure monitor. The emulator receives pressure waveform signals from the non-invasive blood pressure monitor, and receives a transducer excitation voltage from the invasive blood pressure monitor. The emulator converts the pressure waveform signal from the non-invasive blood pressure monitor into an analog signal which is scaled as a function of the excitation voltage. The scaled analog pressure signal is supplied as an input to the invasive blood pressure monitor, and emulates the signal which would be received from a catheter-based blood pressure transducer.
