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.

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.

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“ .

6.2.2 Entries Peculiar to the use of Program 0

When using program 0, the maximum heart rate (HR) should always be entered specific to the individual patient. Since this value serves as the target frequency for loading, it must be specifically adapted to the age and health of the patient. The remaining parameters, in particular the alarm parameter, should be established in the configuration so that even the weak patient can withstand the ergometric session without danger. Here also, all other parameters may be altered for a specific ergometric session.

Always enter the maximum heart rate (HR) for program 0 specific to the

6.3 Preparations for control by ECG or PC

The ergometer must be specifically configured to the controlling ECG-Type or PC, see Appendix. The ECG or PC is then in total control of the ergometry. Any entries that may have been made on the ergometer are therefore nullified. There is no preparation of the ergometer to be made on the console. Configure your ECG or PC in accordance with the appropriate operator’s instructions for ergometry. Start the ergometric session with the ECG or PC.

Assign patient to patient group, and select program for this patient accordingly, or select the

automatic program 0 for patients who you cannot be classified, or select program 9 for

patients who are to undergo heart-steady-state-training.

Possible modification of parameters

Prior to beginning an ergometric session you may alter any parameter for this specific ergometry.

Start of Ergometry

Press the red coloured „START“ key to begin the ergometric session.

Quiescent blood pressure measurement

Immediately after starting the ergometer, the quiescent blood pressure measurement will be taken. It is important that the patient remains absolutely calm during this measurement as the filter parameters for the blood pressure during stress are established by this measurement.

Artifacts during this measurement may lead to false results under stress.

Print-out of the quiescent blood pressure measurement

The resulting blood pressure data will either be printed out on the internal printer or fed to

the ECG via the RS-232 interface and documented there.

6.6 Ergometric Protocol

An ergometric protocol is recorded during the ergometric session. The protocol is either produced by the internal printer or by an ECG. Picture below shows such a protocol as documented by the internal printer. Program parameters were:

heart rate max. = 180, systole max. > 200, diastole max. > 130, initial load Po = 50 watt, maximum load Pmax. = 999 watt, blood pressure measurement interval = 01 min.,

load interval = 01 min., load change per interval = 25 watt. The PWC values to be ascertained were predifined for heart rates between 130 and 150 beats per minute. The values in this protocol are not representative of a patient as they were generated with a simulator.

Sometimes, it may be necessary for the patient to discontinue pedaling for one reason or another. Normally, when the RPM value drops below the minimum value (30 RPM), this will lead to an abort of the load program since a defined load is no more present.

Now it is possible to turn off RPM control for these special applications. The load program is then not aborted, but rather continues regardless of the presence of a minimum RPM value or not. Re-entry into the program is therefore possible at any time.

7.4 Defining an Ergometry Program

The operator may select from 10 different ergometric programs when using the ergometrics er900L. Of these 10 programs, eight are fully programmable, one program offers automatic loading and one program is for pulse-steady-state training.

Ergometric program definition is only possible when the ergometer is controlled

internally, i.e. not controlled by a PC or ECG unit.

Mixed control is also possible, that is, normal control is internal and, when needed, control may be transferred to an external device. For mixed control operations one should ensure that program 8 can be used as a buffer for several interface modes. Therefore, for mixed control operations only programs 0 through 7, or 9 may be used since program 8 will be used for switching the control type.

The monitor program can be used to establish a basic stress program. Program creation is done as follows:

7.4.1 Setup of Automatic Program 0

Automatic program 0 is for the fully automated testing of patients with unknown circulation condition, in particular, weak patients. The ergometer’s control computer uses this program to test the patient’s circulation response across two or three different but specific load increments. The computer then determines three standard load increments within which the pre-set maximum heart rate should be attained. The standard load increments and the corresponding time intervals are taken from the WHO table for stress analysis.

7.4.2 Definition of Programs 1-8

The operator has the choice of eight stress programs that are freely programmable to specific requirements on the ergometrics er900. In these eight programs, all control and alarm parameters are fully selectable. As with programs 0 and 9, the setup accomplished with the monitor program represents a basic setup that can still be changed for any specific ergometry run at the beginning of that particular ergometry.

Program 8 is an exception to this rule in case the ergometer is operated in mixed-

8.1.2 Creating Your Own Load Program

Programs 1-8 were intended to be programmed from the monitor program, as described in this manual, for various pre-defined patient groups. This allows you to select the appropriate program for a patient at the touch of a button. This gives you basic settings with which the stress test of the patient can be performed. You may still change any of the parameters prior to starting ergometry. Such a parameter change, that is not accomplished within the monitor program, is only temporary and effective for this specific one ergometry. Such changes are voided at the end of the ergometry.

This is why, when you use the monitor program to program the load programs, you need to proceed such that only the absolute limits for an entire patient group be pre-set as alarm parameters. The patient specific alarm parameter should then be entered when the program is called up. In general, eight programs with differing load characteristics are adequate to serve various patient group types if patients are grouped by their load requirement patterns. The flowchart below should serve to clarify the process of an ergometry.

Determine the correct patient group for the patient.

8.2 Systematic Setup of Programs

8.2.1 Setup of Automatic Load Program 0

Except for initial load and maximum load values, program 0 does not permit any load settings from the operator. Individual load increments are not programmable. The loading process is determined automatically by the ergometer during the ergometry process and is only dependent upon the circulation response of the patient.

Program 0 is intended for critical patients whose circulatory condition is unknown. It is therefore necessary that the parameters be accordingly conservative. Establish initial load and alarm parameter values such that even very weak patients will not be overstressed. Select blood pressure measurement intervals as short as reasonable in order to guarantee the best possible surveillance over the patient’s circulatory condition.

The program will calculate three standard load increments of 5, 10 or 25 watt within which the patient can reach the pre-set heart rate. The resulting protocol data will enable you to subsequently classify the patient into one of the patient groups for which you have a specific program (1-8).

Even with program 0 it is possible to make temporary alterations to any parameter for the specific ergometric process. The flowchart below should clarify the ergometric process for program 0.

Continuous doctor’s attention is also required for patients who are

stressed with automatic program 0 since the circulatory response is not continuously monitored. Parameters can change abruptly between individual blood pressure measurements without the system being able to appropriately counteract.

Pay attention to the execution of the program when programming. The base values that were entered via the monitor program are not necessarily those that are appropriate for a given patient. When programming you should only enter upper limit values that apply to the largest possible group of patients. Any parameter can still be changed for any specific ergometric run such that the parameters are tailored to the patient. You should also select alarm values that will prevent over stressing even weaker patients but still allow for a meaningful test. Select an initial load that will not overburden the weaker patients. If you don’t the circulation condition will show false results and automatic ergometry is then impossible.

In general, automatic ergometry is only used for acute, mostly weak, patients. Accordingly, you should set the parameters at relatively low levels.

Heart rate is one exception in these parameters. It should only be entered via the monitor program as a nominal value. Adapt this value however, to each individual patient, prior to ergometry. The ergometer works toward attaining this maximum heart rate. Program 0 will try to reach the maximum heart rate by using three standard load increments. You should, therefore, set the maximum heart rate in accordance with the capabilities of the individual patient so as to avoid excessive stresses. It is also astute to provide the ergometer with a continuous heart rate. This can be done with an ear/finger clip, a pulse monitor or with a heart rate feedback from an ECG unit (see appendix).

Operation Manual

Structure of Programs

Enter the maximum heart rate via the monitor program only as a nominal value but

adapt this value to each individual patient prior to ergometry.

You should write your program on one of the programming forms before entering the program on the console of the ergometer. The programming form is an aid that helps the operator maintain an overview of the various parameters. The program forms also represent a permanent record of the programs that are available if the unit should malfunction. You will find blank programming forms in the appendix to this manual. An example of a programming form already filled out can be found in this chapter.

Write your programs on the program forms (as found in the appendix of this manual) before entering them in the console of the ergometer. This contributes to clarity and proper record keeping.

8.2.2 Setup of the Fully Programmable Load Programs 1-8

Programs 1-8 serve to provide the user with a stress program spectrum that will accommodate the patient groups that are to undergo ergometry. Every parameter in these eight programs is freely definable and will be upheld by the ergometer unless an alarm parameter is exceeded or a manual change is made to ergometry by the operator.

In this manual you will find examples of such patient group oriented programs. These example programs are the same as those that are factory pre-programmed prior to shipment. Naturally, these programs can also be overwritten and individually adapted to the wishes and needs of the user.

Pay attention to the execution of the program when programming. Determine the parameters for the various patient groups before you begin to program. Select alarm and load parameters according to average strength characteristics of patient groups. Select parameter values such that most individuals in the group require no parameter changes and those that may become necessary are minor. Reserve a program, preferably program 8, for special patients that require an individualized program. Here then, you can create experimental programs suited to the patient’s specific requirements. To make such and experimental program, set all of the parameters for the selected program (e.g. program 8) to minimum or maximum values, i.e. 0 or 999, so that all automatic control functions are turned off. Then you can enter the actually desired values for this specific ergometry just before starting the session.

For special ergometrics, setup one program (e.g. program 8) as experi-

mental with all maximum or minimum parameter values.

8.2.3 Setup of Program 9, Steady-Pulse (Heart & Circulation Training)

Program 9 is for pulse-steady-state training. The ergometer increments the load from the outset of training according to your parameters. Upon reaching the maximum heart rate setting, instead of causing program termination, the unit switches over to pulsesteady-state control. That means that load changes are calculated to maintain this heart rate. It is absolutely necessary to provide the ergometer with a continuous heart rate signal when running the pulse-steady-state program. This can be accomplished with an ear/finger clip, a pulse monitor or a heart rate feedback from and ECG device.

Once reached, the ergometer will hold the maximum heart rate value stable until an additional alarm parameter is exceeded or the training session is manually ended by the operator.

Structure of Programs

Pay attention to the execution of the program when programming. Since program 9 is a pure training program, alarm parameters (except for heart rate) should be chosen that any danger to the patient is remote. Select a warm-up load parameter (used until reaching the max. heart rate value set) such that reaching the heart rate value will not go to quickly or take too long. When the warm-up phase is too short, reasonable pulsesteady-state training is not possible as the circulatory system has not yet adjusted to the load. When the warm-up phase is too long, the patient is already tired before the actual training phase has been reached.

Program 9 is purely a training program. Parameters must be selected that

reflect the requirements of this mode of operation (as opposed to programs 0-8).

Transmission Protocol:

In contrast to purely digital transmission, ECG type P4 protocol always responds, upon demand, with a standardized data record. The string consists of 54 alphanumeric characters with „Carriage Return“ and „Line Feed“ as line delimiters. The RS-232 will only accept the „S“<CR> command. All other characters will be ignored. Ergometry cannot be terminated with an interface command. Ergometry will automatically terminate, at the latest, six minutes after the test subject ceases to pedal. Blood pressure error measurements are discernible in that all values in the data string are set to „000“.

Control flow with P4 :

Start command sent from controlling device (e.g. ECG)

S<CR>

The ergometer will begin the ergometry by taking the quiescent blood pressure measurement. After

the blood pressure measurement is completed, the following string will be sent from the ergometer.

NR.01,SYST:xxxmmHg,DIAST:xxxmmHg,Pulse:xxx/min<CR><LF>

The pre-set load will be applied after the data record has been sent.

Every subsequent blood pressure measurement

must be requested with the

„S“<CR> command.

After every new start command a new blood pressure measurement will be taken and then the data record

(as below) reported.

NR.xx,SYST:xxxmmHg,DIAST:xxxmmHg,Pulse:xxx/min<CR><LF>

B.1.2 Switching Between Internal and External Load Control

This setting is determines control of the load. Internal control means that the ergometer’s internal program will determine the load. External means that the load will be controlled by the device connected to the analog interface. When the load is controlled externally, the ergometer controls only the blood pressure measurements and data transfer over the RS232 interface. Some interface modes are based upon external load control and others do not permit external load control. (see Appendix A).

D.1 PWC Values

D.1.1 What is a PWC Value?

The PWC (Physical Work Capacity) value is an index of the physical power of a patient at a given heart rate. Empirically derived values for men and women in various age groups are used as objectives. Various authors have established PWC tables. Naturally there are minor performance variations in these assorted tables. To arrive at a standard, PWC values for the following heart rates were calculated:

HR = 130/min. HR = 150/min. HR = 170/min.

These values establish what performance a patient in the assorted age groups should have at a heart rate of 130, 150 or 170 beats per minute to be considered normal for his/her respective patient group.

If only heart rate is considered with regard to a particular performance, the resulting absolute value is of little significance (e.g. 200 watt at HR=150/min.). The patient’s weight must receive consideration with regard to the performance factor in order for the results to be relevant and comparative. Continuing the same example, a patient with a weight of 100kg:

Performance at HR 150/min. = 200 watt

the resulting PWC value is:

PWC150 = 200 watt/100kg

= 2 watt/kg body weight

The following tables from the book „Stress Analysis in Practice“ from Rost and Hollmann can be used as a standard for performance characteristics.

Appendix D: Indicators

D.2 Training Indicator

The system can calculate and print a training indicator when ergometry is complete. These training indicators are reflective of the entire circulation response to the performance invoked by ergometry. This value however only has relevance when it is compared to values from multiple ergometry sessions of the patient over a period of time. These values are very good indicators of the patient’s training progress. The training indicator is calculated by the computer as follows:

training indicator = S - D * HR * M

S = maximum systole

D = maximum diastole

HR = maximum heart rate

M = patient’s weight

P = maximum resulting performance

The training indicator serves to compare multiple ergometric sessions of a single patient. This value is not applicable for the comparison of different patients. Basically, a drop in the value on a patient’s chronologically consecutive ergometric sessions is a positive indication of good training progress.

Appendix E: HR Recording

Ergometer

Type er900L

E.1. Heart Rate Feedback from ECG

When an ECG device is connected to the ergometer it is advantageous to supply the ergometer with a feedback of the recorded heart rate. This allows the heart rate to be continuously monitored as an alarm parameter. When performing pulse-steady-state training a continuous heart rate input is indeed absolutely necessary. If the ECG device used supports a QRS trigger output, this can be connected to the ergometer. There are two possible connections (see appendix C), either the analog interface (J13, Pin 7) or over the opto-input (J11, Pin 2).

E.2. Pulse Monitor

Ergoline offers a pulse monitor, type Polar, that can be used for heart rate input to the ergometer without an ECG. The receiver of the pulse monitor is connected to the opto-input of the ergometer. The QRS impulse is then radio transmitted from the chest strap to the ergometer.
