Overview
ECG Waveforms
The microprocessor has stored in its memory all of the digitalized waveforms. It sends the
individual lead waveforms to D/A converters, which generate accurate analog
representations. The waveforms are then sent through resistor networks, developing the
appropriate signals on the output terminals.
Respiration
Respiration waveforms are provided that have adjustable rates from 15 to 120 BrPM
(Breaths Per Minute) as well as an Apnea (0 BrPM) setting. The signal is generated by
a variation in the impedance in either the LL or LA lead (selectable). The amplitude is
settable from .5 to 3.0 ohms.
Blood Pressure
There are one, two or four 6-pin mini-DIN plug connectors on the right side of the unit
for connection of the Blood Pressure cables. Full blood pressure simulation is available
through these connectors. The circuits are totally isolated.
