Introduction

Section 1

Regular testing of defibrillators and pacemakers is critical in order to ensure safe and effective operation. The BC Biomedical DA2000 Defibrillator Analyzer accurately verifies the output characteristics of all defibrillators as well as testing the parameters of non-invasive pacemakers. The DA2000 is battery operated and completely portable. Simple-to-use menu soft keys allow quick access to tests.

The DA2000 measures the delivered energy in Joules (watt-seconds) from a defibrillator by simulating the human body’s resistance. The analyzer then measures the flow of current through that resistance. The standard resistance used by the DA2000 is 50 ohms. Defibrillator energy is measured in one of two ranges: 0-100 Joules, or 0-1000 Joules.

The defibrillator pulse waveform can be replayed via the ECG jacks or paddle plates for viewing on a recorder, or on an oscilloscope for greater detail.

Synchronization time in milliseconds is measured by timing the firing delay from either the Q-wave (base) or R- wave (peak) simulated by the DA2000. The simulated waveform is present at both the ECG jacks and the paddle plates. Peak voltage and peak current (amps) of the defibrillator pulse can be measured. Overshoot voltage and current measurements of the defibrillator pulse are calculated and displayed.

The DA2000 also measures the defibrillator’s charge time (the time it takes for a defibrillator to reach its maximum charge setting).

Waveforms, including ECG, arrhythmias, and performance, help verify monitor and recorder accuracy, and also test the automatic defibrillator’s ability to recognize and fire.

All waveforms are present at the ECG jacks, the paddle plates and scope output. Utilities allow the setting of Serial RS-232 communication parameters to download results to printer, or computer. Display contrast can be adjusted to obtain the best view of the LCD display.

Upgrading the DA2000

A number of pre-configured DA2000 models are available. In addition, older models may be upgraded by contacting BC Biomedical. The following DA2000 models are available:

•DA2000: Base unit. Features output energy, synchronization time, peak measurements, bi-directional RS-232.

•DA2000W: “Waveform” version. Features output energy, sync time, peak measurements, overshoot, bidirectional RS-232, waveforms, charge time measurements, 28 programmable autosequences.

•DA2000P: “Pacer” version. Output energy, sync time, peak measurements, overshoot, bi-directional RS232, waveforms, charge time measurements, 28 programmable autosequences, pacer output measurements and pacer refractory period measurements.

Front Panel

The front panel of the DA2000 (Figure 1.2) includes the following operating features:

1.Universal ECG jacks that utilize AHA and International color coding, allowing for waveform output to monitor/recorder.

2.A “High Level ECG” Banana jack provides 1 Volt peak output of the selected waveform.

3.The “Common” Banana jack provides ground for the “High Level ECG” and “Defib Scope Out” jacks.

Figure 1.2. DA2000 Front Panel Layout

4.The “Defib Scope Out” Banana jack provides pulse output to an oscilloscope.

5.A range switch allows for defibrillator settings from 0 to 1000 Joules (high), for power below 0-100 Joules (low) for increased accuracy, and a PACER range setting for pacer output measurements.

6.The Power switch enables the DA2000 (I = ON, O = OFF).

7.LCD display: 24 characters x 2 lines. The upper line of the LCD display provides messages and test results, while the bottom line displays menu choices.

8.Five “soft keys” can be used to select the desired function highlighted on the lower line of the display.

9.Two nickel-plated Defibrillator Paddle Plates are available for defibrillator paddle contact. All waveforms are present at the paddle plates simultaneously with the ECG jacks.

Back Panel

The Back Panel includes a battery holder that houses a 9-Volt alkaline battery, and a DC battery eliminator jack. An RS-232 D-9 pin Serial Port allows communications to a computer, serial printer or other test equipment.

Installation & Operation

Section 2

Use the following checklist when unpacking the DA2000 to check the instrument for shipping damage. Perform a visual inspection to ensure the front panel or case has not been damaged during shipping.

Check the LCD display to ensure that it is intact. If the DA2000 has been damaged, call your BC Biomedical representative immediately.

Place the DA2000 on a level surface and power up the instrument by turning the power switch to I (ON). Check the display. If the message, Warning - Low Battery!! appears, the instrument's battery requires replacement.

Operation Warnings

The operator must be familiar with, and follow the safety precautions listed detailed below, before using the DA2000 with a defibrillator:

•Inspect the defibrillator daily. Examine the paddles, lead wires, and power cord for cracks and frays.

•If the defibrillator is line powered, be sure that it is plugged into a grounded receptacle. Do not touch the electrical contact surfaces of the defibrillator paddles.

•Grip one paddle handle firmly in each hand. Apply to the DA2000 plates. Keep the paddles firmly depressed to prevent arcing that can cause injury to the operator and/or damage the DA2000 or defibrillator.

•Do not touch the contact plates on the DA2000 when the defibrillator paddles are being pressed onto the plates. Do not use any electrical paste or pads when testing a defibrillator with the DA2000.
