Arrhythmia Functions
Conduction defect
The MPS450 simulates 36 types of
arrhythmias, such as systole PVCs, systole,
systole, tachycardia, fibrillation, flutter, and
systole. Simulated conduction defects include
first-, second-, and third-degree heart block;
and left- and right-bundle-branch block.
Square/pulse/triangle/sine
R waveforms
Wave amplitude
ECG-Performance Testing
R-wave rate and width
The MPS450 generates square, pulse,
triangle, sine, and R waveforms for
performance testing. Wave amplitude is
adjustable, as well as R-wave rate and width.
Respiration lead
Baseline (impedance)
Respiration rate
Respiration amplitude
Respiration
Apnea simulation
Calibrated respiration rates are generated
from 15 to 120 BrPM (breaths per minute),
including four respiration-impedance
selections, with two different lead selections
(LA or LL). The output-impedance level is
adjustable to 500, 1000, 1500, or 2000 ohms.
The MPS450 generates apnea pauses (0
BrPM) of 12, 22, and 32 seconds, as well as a
continuous-apnea condition.
BP sensitivity
BP zeroing
Static-pressure levels
Dynamic BP waveforms
BP respiration artifact
Blood Pressure
Swan-Ganz simulation
The MPS450 simulates static and dynamic
invasive pressures, providing complete blood-
pressure simulation. The MPS450 also
provides calibrated static pressures and
dynamic waveforms to simulate signals such
as pulmonary-artery, left- and right-ventricle
and Swan Ganz (RA-RV-PA-PAW) pressures.
Temperature Temperature settings The MPS450 provides four preset
temperature simulations: 0 °C, 24 °C, 37 °C,
and 40 °C. All temperature simulations are
compatible with Yellow Springs, Inc. (YSI)
Series 400 and 700 thermistors.
Injectate temperature
Injectate flow
Faulty-injectate curve
Left-to-right-shunt curve
Cardiac Output (Option)
Calibrated pulse
The MPS450 simulates cardiac-output
waveforms for testing the accuracy and
sensitivity of cardiac-output computational
devices equipped with Baxter-Edwards-type
catheters. Injectate temperature can be set
either to “iced” or room-temperature
conditions, with adjustable flow rate (in liters
per minute). The MPS450 also simulates a
faulty-injectate curve, as well as a left-to-right-
shunt curve.
