Operator manual Corival

This is the short operator manual for the Lode Corival Ergometer, which describes the

basic actions for starting up your ergometer. For a complete description, we refer to our

User Guide.

Intended Use

A Lode ergometer is a diagnostic tool intended to be used as a stress test device in a medical
environment. The main goal of the use of a Lode ergometer is to create reproducible stress
tests. The following parameters can be measured:
Workload (watt)
Revolutions per minute (rpm)
Time (minutes and seconds)
Distance (km)
Optional: Blood Pressure (mmHg)
Optional: Heart rate (beats per minute)
Optional: Energy (KiloJoules)
Optional: SpO2

In combination with other diagnostic tools, like ECG or pulmonary function equipment, other
important physiological data can be obtained, allowing a physician to evaluate a test subjects
physical status.

A Lode ergometer is designed both for manual operation and for control by external ECG-,
pulmonary equipment. In combination with optional software, the ergometer can also be
controlled by a PC.

The ergometer has to be operated under the supervision of well-trained medical specialists,
like cardiologists, pulmonologists and physiotherapists. The ultimate judgment whether a test
subject should undertake a stress test with an ergometer and which protocols should be used
must be made by the responsible medical specialist, based on the limitations of each
individual, the medical history and all other applicable circumstances. Neither Lode BV nor
its distributors assume any responsibility for the final use of its equipment.

Contra Indication

The Corival ergometer is to be operated by classified personnel only. As stated in the intended
use, the Corival is intended to be used in a medical environment. During the intended use the
test subject will deliver energy. Application of the wrong dosis of energy could lead to
permanent damage of the test subject health.

Maintenance

The Corival should be calibrated once a year. In case any damage is observed of the Corival
Lode B.V. or his representative should be informed in order to execute the necessary
repair(s). Service of the Corival is restricted to factory-trained personnel only.

Precautions

Caution:

This device should only be sold by, or on the order of authorized persons.

Operator manual Corival

Caution:

Not suitable for use in the presence of flammable anaesthetics.

Note: The voltage selector (115/230VAC) is inside the ergometer. The main unit panel has to
be unscrewed. Voltage selection should be done by a technician!

Possible hazards

Using the Corival according to intended use, contra indications, maintenance, precaution and
common sense stated above may not eliminate all hazards. Possible residual hazards could be:

3 System parameter

In the System Parameters different specific ergometer settings can be carried out.

3.1 Set display

This function allows you to adjust the parameters which can be read out on the display during
exercising. If more then 2 are set to ON they are shown in groups of 2 scrolling. Choosing
default allows you to go to factory settings for the display parameters.
Press the

( )

button to go to the next parameter and switching the actual parameter ON/OFF is

done with ▼▲ keys.

3.1.1 Power

Power indication in watts can be switched ON or OFF using the ▼▲ keys. The power
displayed is the actual power of the brake. This means that regulation speed is incorporated.
When rpm drops below 25 rpm the load is removed at once, because the pedal torque
becomes very high. Load is put on the brake when rpm is greater or equal to 30 rpm.

3.1.2 RPM

Switch ON or OFF the Cadence readout in Revolutions per minute. The rpm can always be
read out by the LED bar graph on top of the display independent of this adjustment.

3.1.3 Heartrate

Switch ON or OFF the Heart rate indication in beats per minute. The ♥ symbol is used in the
display.

3.1.4 Torque

Switch ON or OFF the Torque in the readout. The Torque is displayed in Newton meter.

3.1.5 Timer

Switches the Timer ON or OFF in the readout. The timer is shown in the display as:

Θ =

mm:ss

. The timer starts when you enter manual, terminal or analog mode and the rpm

increases above 30. The timer is reset when one of these modes is left.

3.1.6 Distance

Switches the distance ON or OFF. The distance is shown in the display as:

→ = 99,9 km,

expressing the distance in km. A fictive formula is used (see main manual), holding only for
average cycle conditions and it should not be used for diagnostic purposes.

3.2 Set P-slope

The load regulation steepness is set by this parameter to the default norm-value of 25 watt/sec
or to maximal. During the Wingate sprint test the P-slope has to be unlimited.

Operator manual Corival

11

3.3 Set mode

Set mode is used to define which parameter (like load, torque, heart rate and linear constant
alpha) has to be adjusted during exercising in MANUAL mode with▼▲ keys

3.3.1 Hyperbolic

Hyperbolic mode means that the load P can be adjusted in watt. The load is kept constant
independent of rpm.

3.3.2 HR controlled

Heart rate can be adjusted and the load is regulated until the adjusted heart rate is reached.
This means when heart rate increases above the adjusted level load is decreased and the other
way around.

3.3.3 Linear

In linear mode the load P is coupled with rpm using the following formula:

P [W] = α* (n [min-1] )

2

The linear coupling constant α is the adjustable parameter in this case.

3.3.4 Fixed Torque

In Fixed Torque mode the load is regulated such that the torque is kept at a set fixed value,
according to the formula:

T [Nm] = (P*60) / ( 2 * π * n [min-1])
Note: be aware of the fact that this fixed torque mode is not the same as the constant Torque
mode which is used with the Wingate software module (see for more information the Wingate
manual).

3.3.5 Isokinetic (only available for Excalibur Sport 925900)

In the Isokinetic mode the rpm is kept constant during the exercise, according to the formula:

P [W] = ( 2 * π * n [min-1]*T [Nm]) / 60

During the exercise you can not pedal faster then the chosen rpm. You can deliver more Force
with the same speed and produce more workload in this way.

Note: The rpm is the adjustable parameter in this case, this mode can be used to define the
optimal rpm.

3.4 Settings

Under settings all device specific and interface adjustments can be made. It concerns to all
those items not related directly to ergometry.

3.4.1 Default Startmenu

Normally your ergometer starts in the main menu. But you can modify this menu to your own
desired settings. This is convenient when your ergometer is used often in the same setting,
The following menus can be selected as startmenu: MAIN MENU; MANUAL; TERMINAL;
ANALOG At the next startup of your ergometer the selected menu will be activated.

Operator manual Corival

12

3.4.2 Keyboard On/Off

If you do not want to interrupt a training or you do not want the test subject to interrupt the
training by pressing a key accidentally, the possibility is offered to disable the keyboard
Now you wonder how to get back the control to the keyboard. Act as follows:
Switch off the ergometer
Switch it on again while keeping the

( )

button pressed. Now you have back the control. Go to
SYSTEM PARAMETERS / KEYBOARD ON/OFF and set it to ON.
At the next startup of the ergometer the keyboard is enabled again.

3.4.3 Test Functions

For servicing and calibration of the device a number of diagnostic tools is available in the
software. They are hidden under Test functions. You need a safety code to enter the
TESTFUNCTIONS.

3.4.4 P In/Out Analog

The ergometer can be controlled by an external device which has an analog output only. This
is done using the ANALOG mode. With P In/out Analog the analog scaling can be adjusted:

- 1 V analog in - can correspond with a workload of 100 W / 200 W / 500 W.

3.4.5 TC Bytes

The Test code (TC) Bytes offer in case of malfunction or poor performance of the BP option
the possibility to make error codes visible. Your local distributor can help you diagnose the
problem with the Error Code.

3.4.6 RS232 Protocol

When the ergometer is externally controlled via RS232 a protocol should be selected here.

3.4.7 Language

You can choose different languages for the ergometer.

3.4.8 Device No

When RS232 communication is used with the ergometer, it is identified with a so called
device number. This offers the possibility of looping through ergometers.

A Maintenance

The Lode Ergometer is mechanically and electronically designed for durability and accuracy.
This also accounts for the options and add-ons of the device. The frequency of calibration
depends on the intensity of usage. As a rule Lode Ergometers are calibrated on an annual
basis. Please refer to the Service Manual for specific details on check-up intervals for the
Lode Ergometer and its options and/or add-ons.

The dynamic calibration is performed using calibration equipment specially designed by the
manufacturer.

A.1 Cleaning

The housing of the Corival ergometer and all other external surfaces can be cleaned with a
cloth dampened with non-aggressive liquid.

A.2 Replacing fuses

You will not need a certified technician to replace fuses of the Corival.

Always disconnect the power cord first!

Unplug the mains cable. The fuses are part of the main unit (Fig. 3 Main unit panel
connections, item 8) and located at the bottom of the main unit. You have to lift the Corival
place it in the upright position (90°) to locate the fuses. Unscrew the fuse holders with a
screwdriver, replace the broken one and place them back again. Note: make sure that the fuses
that are in the Corival match the set voltage (115 V: 2 x 1,25 A slow; 230 V :2 x 0,63 A
slow).

switch your KEYBOARD ON or OFF. With the programmable control panel the basic (test
subject) side of the unit is default OFF. It is possible to control the ergometer with the buttons
of the basic control panel instead of the programmable control panel. You can use this option
for service purposes or to program the display of the basic control panel. During the startup of
the ergometer you can press one of the buttons at the basic side to switch operation to this
basic control panel, you will then loose the control function of the programmable side. To go
back to the default control situation you have to restart the ergometer without pressing any
button.

The TEST FUNCTIONS are only available at the basic control panel. They are meant for
service personnel only. Contact your supplier in case service of the device is required.

S= step

the workload can be adjusted + or – and the duration of this hyperbolic
stage can be determined; the load is independent of the RPM.

T= torque

fixed torque: the torque in Nm can be adjusted with certain duration.

L= linear

the workload is coupled with RPM with constant α as the adjustable
parameter for the desired duration; load P = α * N2 [W] goes up with
square of cadence.

H= heart rate

the workload is regulated as a function of the adjustable heart rate for a

certain duration in this heart rate controlled step.

P= proportional

the workload is increased linear as a function of time (ramp protocol). It
will take the total duration time to reach the programmed workload;

R = Repeat

repeat steps (until max. workload): you have to enter the workload step and
the duration of the step only once.

Recovery

the recovery stage is the last stage of a protocol with a fixed workload and
an unlimited duration (only 1 recovery stage in 1 protocol)

After the confirmation of the workload during the recovery stage the menu PROGRAM BPM
will appear. Toggle with the ▼▲ keys for the measurement possibilities:

C Heart rate option 928924

C.1 Connecting the Heart rate system (option 928924)

To install a heart rate option purchased afterwards, follow the instructions given in the user
guide supplied with the ergometer. Installation of the Heart rate option itself has to be done by
service personnel only.

C.2 Using the Heart rate option

The heart rate option is automatically recognized by the ergometer. The Polar belt should be
mounted around the chest of the test subjects (at heart level) with Polar trade mark pointing
forwards from the middle of the chest. The belt should not be to loose. If you have a weak
signal, check following tips:

•

Wet the contacts on the right and left backside of the Polar belt for good contact

•

Stay near the receiver (within a range of 0.8 meter) which is located in the display unit
at the test subjects side below the readout.

•

Due to the integration measurement principle it can take a few seconds before the
readout on the display shows the correct value. Be patient.

•

The test subject should be positioned in such way that a straight virtual line can be
drawn between the Polar trade mark on the belt and

the receiver inside the display

unit, or placed in front of the Test subject

C.3 Installing the BP cuff

To install a B option purchased afterwards, follow the instructions given in the user guide
supplied with the ergometer.
Installation of the Blood pressure measurement module itself has to be done by service
personnel only.

With option 928817, -818, 820 it is possible to perform stand alone or external controlled
blood pressure measurements. After installation the BP module is recognized automatically at
start up of the ergometer, indicated by the following screen for a few seconds:

D.1 Using the BP system

Caution

: Carefully read the instructions in Appendix D.2 Patient Hook-up before continuing.
Only well trained medical personnel, familiar with BP measurement, should operate the BP
system.

When you are in the MANUAL, TERMINAL or ANALOG mode you can go to the BP
measurement by pressing

( )

button. The following menu appears:

In the upper line of the display still your selected readout parameters appear. The buttons
below have the following functions:

▼ dis

: Toggle the display between your readout parameters and the pressure p [mm

Hg]. Pressure is indicated as lower case p and workload with upper case P.

▲

►

: The BP measurement starts:

With the same button the BP can be aborted at any time and the pressure will be released.

( ) MAN / TERM / ANA

: Return to the operation mode where you started from

(MANUAL, TERMINAL or ANALOG).

During the first BP measurement of the test subject the cuff inflates to 180 mm Hg. For each
subsequent BP measurement, the last measured SYSTOLIC value +50 mm Hg is used as a
maximum inflation limit. Be aware that in case of an error (D.3) the inflate limit can go up to
260 mmHg worst case. Above 300 mm Hg, or if a measurement lasts longer than 180
seconds, the hardware releases pressure immediately for safety reasons. Deflation is done 40

Operator manual Corival

29

mm Hg below the last measured DIASTOLIC pressure. The used deflate rate is
approximately 4 mm Hg/heartbeat.

A list of most occurring warnings and errors is given in D.3 Abort codes BP system.
The built-in BP module offers, in case of malfunction or poor performance, the possibility to
make error codes visible. See for more information the user guide supplied with this
ergometer.

Caution

: The interpretation of the error codes should be done only by experts. Ask your
supplier for more information.

D.2 Patient Hook-up

Correct patient hook-up is very important. Experience has shown that a lot of troubles can be
avoided when the rules below are kept in mind. Especially BP measurement using Korotkoff
tones under stress requires accurate preparation.

D.2.1

Apply the cuff

On the inside of the upper arm you can feel the brachial artery. Palpate the brachial artery to
ensure proper placement. The best place for the microphone is where you can most clearly
feel the pulse (Fig 2: Palpating the arm). Upper clothing should be taken off!
Pulled up garments should not jam the upper arm.

D.2.2

Position of the cuff

The cuff should be placed on the upper arm, so that it is positioned about 2 cm above the
elbow close to the heart level (Fig 3: Cuff position). Place the microphone on the position that
you palpated.

Fig 2: Palpating the arm

Operator manual Corival

30

Caution: Never place the cuff so that the microphone is located in the elbow.

Pull the cuff so tight, that it neither moves nor ties off the arm of the patient. By fasten the
cuff too tight or too loose, error measurements are caused.
Wrap the end of the cuff around the upper arm and close the Velcro fastening (Fig 4:
Mounting the cuff).

Ensure that the air hose from the monitor to the cuff is not compressed, crimped or damaged.
During ergometry the air hose should be handled and attached in such a way, that vibrations
and movement artefacts are avoided. Use the ring strap to fix the tubes to the wrist to avoid
tensions on the cuff due to moving and pulling tubes.

During the measurement, which starts with inflation, the arm with the cuff should be
kept in rest.

With ergometry it is most convenient for the patient to take the arm from the

handlebar of the ergometer and relax the arm with the cuff.

Fig 3: Cuff position

Fig 4: Mounting the cuff

Operator manual Corival

31

The intervals of the measurements should not be too short. Intervals of 2 minutes and more
result in long pauses between the stenoses, so that venous congestion and artiospasm can be
avoided.
