General Overview

Congratulations on selecting the AccuPulse™ NIBP Simulator for your non-invasive

blood pressure (NIBP) monitor testing and simulation needs. AccuPulse is the first

"third-generation" NIBP simulator on the market, and is the result of Clinical Dynamics'

15-year leadership in NIBP simulation technology. AccuPulse provides everything

needed for quality–control testing of any oscillometric NIBP monitor, including the

following:

• Optional Selectable CalTables™: AccuPulse's new CalTable™ Technology provides

the first NIBP Simulator to accurately test NIBP monitors. Selectable CalTables™ is

the answer to the industry's issue of accurate and consistent testing of NIBP

monitors with NIBP Simulators. Select the appropriate CalTable™ on AccuPulse and

then use the defined presets for accurate NIBP monitor testing.

• Using the appropriate CalTables™ means the NIBP monitor readings can be

expected to match the AccuPulse BP settings

• CalTables™ are available for several popular NIBP monitors, with the ability to store

45 CalTables, updates are field upgradeable.

• AccuPulse simulates physiologically correct waveforms, the proper way to correctly

test and validate a NIBP monitor.

• AccuPulse's Simulation Engine is designed with very low friction components,

resulting in virtually no wear.

• 7 Adult presets cover the full Hypo through Hyper range.

• 6 Neonatal presets cover the entire range from 35/15 to 150/120

• Autosequences in both Preset and optional User Defined modes.

• Shift of the presets is available to test between the presets if needed.

• Pulse rate can be changed by the user.

• Patented NIBP Simulation Technology - U.S. Patent 5,027,641

• AccuPulse always tests with the NIBP Monitor cuff, which can be a major source of

problems.

• AccuPulse provides a high accuracy digital manometer.

• AccuPulse is half the weight of most other full featured NIBP Testers and includes

an internal battery.

• AccuPulse has a Graphical Display. This allows it to provide a display of the cuff

inflation/deflation waveform, which can be useful for diagnosing unusual NIBP

Monitor behavior.

• Integrated cuff support for adult and a provided accessory neonatal support.

• Internal Pump

• Leak test

• Over-pressure, "pop-off" valve test

• Internal LiOn Battery with intelligent charger

• Comprehensive library of remote control commands

• Optional User Defined mode allows for independent Systolic and Diastolic settings to

be set and adjusted for specific equipment and advanced test requirements.

• Optional Motion simulation software module.

• Optional Arrhythmia simulation software module.

Section 2. Functional Description

General

The AccuPulse NIBP Simulator provides accurate verification testing of blood pressure

monitors. AccuPulse is the first accurate NIBP Simulator that uses physiologically

correct waveforms for testing blood pressure monitors.

AccuPulse Plus includes these test modes:

Blood Pressure Test Mode: Selectable presets with physiologically correct Adult and

Neonate non-invasive blood pressures provide accurate verification testing of blood

pressure monitors. AccuPulse also provides the widest adult and neonatal simulation

range of any NIBP Simulator.

Leak Test Mode with High Accuracy Digital Manometer: Automatically tests the

leak rate of the blood pressure monitor, cuff and hose assembly. The user can configure

and save 3 test combinations for use where the requirements vary. This mode also

provides a high accuracy digital manometer.

Over-Pressure Test Mode: Automatically tests operation of the blood pressure

monitor's pressure relief valve and records the set point when pressure is released by

the relief valve.

Meter Mode : In addition to the 0.1 mmHg resolution manometer, this mode offers

automated inflation to preset values or a user defined set pressure to verify static

calibration across the entire range. The units of measure for this mode can be changed

by the user if desired.

NOTE: The unit may periodically zero itself at 1 minute intervals so that any drift is

removed. There will be a slight audible click heard when this occurs. This will happen

automatically, and only when the system is not inflated or actively testing.

Oscillometric Blood Pressure Measurement Principles

Unlike auscultatory NIBP measurement which uses a stethoscope or microphone, the

oscillometric method uses the pulses or oscillations in the cuff pressure to determine

the patient's blood pressure. The cuff is inflated above the systolic pressure then deflated

linearly or step-wise. When the cuff pressure is high, the pulse amplitude is small; but

as the cuff pressure decreases, the pulse amplitude increases and then begins to

decrease. During deflation, the amplitude of each cuff oscillation is measured and stored

along with the cuff pressure at which the oscillation occurred. The oscillation amplitude

is then plotted against the cuff pressure to produce the "oscillation envelope" curve. The

oscillation envelope is then used to determine the patient's blood pressure. It is widely

accepted that the mean arterial pressure (MAP) occurs at the peak of the envelope,

where the cuff oscillation amplitudes are maximum. Unfortunately, there are no

generally accepted formulas for determining the systolic and diastolic pressures. NIBP

monitor manufacturers have developed unique, proprietary algorithms for estimating

the systolic and diastolic pressures from the oscillation envelope.

Selectable CalTables™: AccuPulse's new CalTable™ Technology makes it the first

NIBP Simulator to address the variations of algorithms between different NIBP monitors.

Selectable CalTables™ is the answer to the industry's issue of accurate and consistent

testing of NIBP monitors with NIBP Simulators. Select the appropriate CalTable™ on

AccuPulse and then use the defined presets for accurate NIBP monitor testing.

AccuPulse can store up to 45 defined CalTables™ for accurate testing of NIBP Monitors.

These CalTables™ are approved for testing and developed by working directly with the

NIBP monitoring manufacturers to assure accurate testing. New CalTables™ are

continuously being released, please visit our web site, www.clinicaldynamics.com, for

updates.

The Generic Preset included represents no particular manufacturer's algorithm but

rather is a middle of the road approximation which will provide repeatable results as in

all prior generation NIBP simulators.

The Generic Preset can be tuned by the user for a particular need when appropriate. The

optional User Defined software module expands this capability and provides storage of

up to 45 custom presets for special applications and power users.
