Foreword
Foreword:
We are pleased that you chose to purchase our computerized ergometer ergometrics er900L.
This is the appropriate decision for quality and performance in heart/circulation testing.
The computerized ergometer er900L has been specially designed with the medical and
ergonomic requirements in mind for quick and definitive stress analysis of the heart/circulation system. Computer control makes a fully automatic process of the entire spectrum of
ergometrics. Numerous programming options ensure that for every patient type there is an
applicable specific stress or training program ready at the touch of a button. Manually controlled stress analysis can also be carried out by the operator, independent of programs,
through manual entry of the load data. Programs in progress may also be interrupted to
control subsequent load steps by hand.
The built-in automatic blood pressure meter was especially designed for ergometrics. It
assures that systole, diastole and heart rate limits are continuously, automatically, monitored
even under stress condition. The computer controlled execution of all measurements and
analysis of results markedly simplifies the work of operating personnel. Accordingly, the
patient can be more closely observed and instructed. This allows the ergometric process to
be performed with the highest level of safety.
The display integrated into the console provides the operator continuously with current measurement data. The integrated printer provides continuous documentation of all measurements
resulting from the ergometric process.
This handbook is intended for operators of the unit. It explains all the functions of the ergometer in detail and in such a manner that operation of the unit can be learned through its use. It
can also be used as a reference.
We hope that you are successful in your work with the ergometrics er900L ergometer. We
always welcome your constructive remarks and improvement suggestions with regard to the
unit as well as to this handbook.
Your ergoline team

5.1 The Computer - Your Helper
The half-leaning/leaning ergometer er900L was designed so that ergometric processes
could be conducted
simply - quickly - exactly - safely.
In order to achieve this, the computer is an indispensable aid. The integrated and especially designed blood pressure module for the ergometric process, makes computer
monitoring of the patient and his blood pressure condition largely autonomous. The
schematics below demonstrate the versatility of the unit .
Automatic Load
Program No. 0
Load program for patients whose
circulatory condition is not clear.
The ergometer tests the condition
of the patient’s circulatory system, and then selects an optimal
load program for the stress test.
With Circulation
Monitoring
Blood pressure and heart rate are
sampled and documented at the preset time interval. Heart rate and blood
pressure are simultaneously monitored for alarm limits and, if necessary, cause an alarm and abort the
load program.
Load Programs
No. 1 through 8
These load programs can be defined by the operator. Selection of
up to 12 load increments is possible. Blood pressure measurement
interval and parameter monitoring
are fully selectable.
Without Circulation
Monitoring
Blood pressure module is off. The
circulation condition is not monitored
and exceeding alarm limits do not
cause an alarm.
Manual Intervention
The preset program can be interrupted
at any time and the load levels may
be manually altered. When circulation conditions are being monitored
only load increments are interrupted.
Circulation data will continue to be
sampled, documented and checked
against alarm limit values in the preset time interval.
Load Program No. 9
Pulse-Steady-State
Special program for pulse-steadystate-training. A selected heart
rate will be maintained stable over
the entire training period.
Experimental Program
Prior to starting the program, each
program may be altered for this specific ergometry. These alterations are
not stored, and the standard settings
are restored after this ergometry.
Such sessions can also be manually
controlled and run with, or without,
circulation monitoring.

5.3 The Printer
5.3.1 Configuration of Printer
The printer may be configured in any one of three modes. This is done by pressing the
brown key „Printer“ (13). The status of the printer can be read from the lower right
corner of the display. The various configurations have the following meaning:
INT = The integrated system printer is enabled and prints all displayed parameters
immediately after each load change and/or blood pressure measurement.
EXT = The integrated printer is disabled. All data are exported to another system (ECG,
PC or external printer) and printed there.
OFF = The printer is turned off. (This setting is only valid for the current stress test and
will revert to „INT“ as soon as the current stress test is terminated.)
5.3.2 Printed Parameters
The printer documents all parameters that are shown in the display. Printing will occur
immediately following each load change and/or blood pressure measurement. Printing
will also occur after the recovery period when the ergometry is aborted or comes to a
programmed termination. There are three parts of the ergometric protocol:
2. Recovery Protocol:
Documents each blood pressure measurement during the recovery phase.
1. Loading Protocol:
Documents the blood pressure reading
at rest , at each load increment and after each blood pressure measurement
during the load phase and the elapsed
time at termination.

3. Summary Protocol:
A summary of the ergometry with the PWC
values at the end of the total ergometry.

6. Ergometry Process
6.1 General Preparations
6.1.1 Preparing the Patient
As support for getting on or off the ergometer, the patient may only use hand
grip (A). The arm rest (D) and the hand grip (C) must not be used as support
for getting on/off the ergometer and must not be strained with the whole body
weight.
1) Place the backrest of the ergometer at a 45 degree angle so that the patient may
comfortably take his place.
2) Position the shoulder and headrests (C) such that they are outside the backrest area.
3) If there are leg rests (B), remove them, or at least the one on the side that the patient
will step up on.
4) Have the patient take his place on ergometer and put his feet on pedals.
5) Put the patient in the optimal position, such that his outstretched leg makes an angle
of 170 degrees between upper body and upper leg. Fix this position by adjusting the
saddle.
6) Now move the shoulder and headrests (C) such that the shoulder supports lightly
touch the shoulders.

7. Applying the Blood Pressure cuff :
* Feel for the position of arteria brachialis and position microphone (identified by
the red tab) precisely above arteria brachialis (E).
* Apply the airless cuff tightly at upper arm in order to prevent slipping during the
ergometry test, however not extremely tight.
* Apply cuff directly on skin, i.e. you must not use an intermediate layer out of
cloth, paper, .....
* The cuff should not touch the elbow.
* After application of cuff, the patient shold use the arm rest (F) as support (and
reduce thereby movement artefacts)
* Check that the cuff tubing is unimpeded and will not knock against any objects
when the patient has placed his hand at the handlebars and starts pedalling.
Move the armrest (D) accordingly toward the head or toward the leg. The con-
necting tube for the cuff should be as free as possible and not crimped or pinched
in any way.
* Advise the patient to keep his arm as still as possible during an ongoing
blood pressure measurement, and especially to avoid extreme contraction
of muscles of the upper arm.
E
- Microphone precisely above arteria brachialis
- Microphone position identified by red tab (cross)
6.1.3 Preparation for ECG Acquisition
- Since in leaning/half-leaning ergometry
electrodes cannot be placed on the
patient’s back or extremities, position the
electrodes as shown in figure.
- Configure your ECG unit according to your
needs and proceed as described in this
manual in Chap. 7.4 „Ergometry Programing“ .
