ABSTRACT:
A device and method for simulating the heartbeat, pressure, and respiration waveforms of a human being. A memory contains a plurality of sets of individual digitized samples of unique hearbeat rhythms. Another memory means contains a set of individual digitized samples of increments for generating a pressure waveform. A primary rhythm and a heartbeat rate are selected by an operator via a key pad. Optionally, a secondary rhythm and a number associated with that secondary rhythm is selected via the key pad. Also, a respirator rate and systolic and diastolic levels of blood pressure can be selected via the key pad. The selections can be stored in a user memory for future recall or they can be used for the immediate production of waveforms. The key pad communicates with a processor, preferably a microprocessor. The processor has program memory and data memory. The processor also has a plurality of bidirectional input-output ports. A first digital-to-analog converter communicates with one of the ports and outputs a signal simulating a heartbeat. A second digital-to-analog converter communicates with a second port and outputs a blood pressure waveform. A variable impedance circuit is the output for the respiration signal.
