OVERVIEW

1.1 Introduction

GENERAL DESCRIPTION

The MiniSim 1000 Multi-Parameter Patient Simulator is an advanced microcontroller
based instrument. It is designed to simulate patient signals of ECG, arrhythmia, invasive
blood pressure, respiration, and temperature. The device also simulates square, sine,
triangle, and pulse performance waveforms.

The easy to operate MiniSim 1000 is menu driven via eight tactile feel soft keys. All
functions are displayed on a two line sixteen character LCD display.

The small hand held instrument is powered by one 9 Volt battery or an optional AC
adapter. The MiniSim 1000 is CE marked and shipped with a Certificate of Calibration
traceable to the NIST.

The MiniSim 1000 is a rugged instrument that performs its simulations quickly,
accurately, and with ease.

QRS and T waves are generated with the following values:

QRS: Rate

T Wave Duration 180 ms

QT Interval

350 ms

T Wave Amplitude 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, and 1.2 mV .

In the automatic test sequence the T Wave Amplitude steps through the changes at one minute
intervals. The display indicates the T Wave Amplitude and the QRS Rate.

As the T wave amplitude increases, the first value at which the patient monitor counts the T wave at 80

8 BPM should be noted. This value should match the patient monitor manufacturer’s specification.

PPR: Pacemaker Pulse Rejection.

The test sequence cycles through normal paced rhythm (AP),

ineffective pacing (Asynchronous Pacing ASP), and pacemaker pulses alone (PCR).

For normal pacing (AP),QRS and pacer waves are generated with the following values:

QRS: Amplitude 1 mV

Width

100 ms

T wave: Amplitude 0.2 mV

Duration 180 ms

Q-T Interval

350 ms

R-R Interval

1 Sec

Pacer: Amplitude 2 mV, -2 mV

Width

2 ms, 0.1 ms

For ineffective pacing (ASP), the values of the QRS and pacer waves are the same as normal pacing
except for the QRS rate that becomes 30 BPM and the pacer rate that becomes 80 BPM.

During the ASP and AP test sequences the display will show the pacer amplitude, the pacer width, and
the QRS rate.

For pacemaker pulses alone (PCR) the values generated are:

Pacer: Rate

60 BPM

Width 2.0 ms, 0.1 ms

Amplitude 2 mV, -2 mV

During the PCR test sequence the display will show the pacer amplitude, the pacer width, and the QRS
rate.
Each set of values in the test sequence is generated and displayed for 20 seconds.

TAC:

Time to Alarm for Tachycardia.

The TAC test is designed to measure the time it takes for the

patient monitor to alarm after the onset of ventricular tachycardia. The low and high alarms on the
patient monitor should be set at 60 BPM 100 BPM before starting the test.

This auto test sequence generates a QRS wave form at the rate of 80 BPM alternating with a ventricular
tachycardia waveform with rates of 206 and 195 BPM and amplitudes of 1.0, 0.5, 2.0, and 4.0 mV.

Each waveform is generated for 20 seconds and the display will show the amplitude and the rate of the
waveform being generated.
