Safety precautions when operating with other devices
Portable communication devices, HF radios and devices labelled with the symbol (non-ionic elec-
tromagnetic radiation) can affect the operation of this device (see section 2.7).
2.7 Eliminating electromagnetic interferences
1. The unit is only designed for operation in the following electromagnetic environment: Ra-
dio frequency emission according to CISPR 11, group 1, class B.
2. Group 1 means that the ergometer exclusively uses HF energy for its internal function. The HF emis-
sion is therefore very low and unlikely to disturb electronic devices in the vicinity.
3. Class B means that the ergometer is suitable for use in any facilities including residential areas, even
if it is directly connected to the public mains that also supplies residential buildings.
4. The general electromagnetic environment with regard to the device's electromagnetic immunity is
defined as follows: the voltage corresponds to the typical business or hospital environment, and the
humidity is at least 30%, especially if the floors are synthetic.
5. If disorders should nevertheless occur, especially in the vicinity of devices labelled with the symbol
"non-ionic electromagnetic radiation", check the recommended minimal distance according to the fol-
lowing table. More information is given in the service manual.
Recommended safety distances between portable and mobile HF telecommunication devices and
the ergometer
The ergometer is designed for operation in an electromagnetic environment with controlled HF disturbance.

4.3 Blood pressure cuff for 250
The standard blood pressure cuff (order no. 24-10-301) has Velcro fixing. It can be used for arms up to
45 cm in diameter. A larger cuff (order no. 24-10-321) is available for larger arm diameters.
A microphone is installed in a microphone pocket on the inside of the cuff. It serves the transmission of
the blood pressure sound.
The connection cable with an air and a microphone connection is 110 cm long. This is a sufficient length.
It ensures that the cable does not dash against the ergometer during pedalling. This is to prevent unnec-
essary artefacts that might result in inaccurate blood pressure measurement. Longer cables (200 cm) are
available but it is imperative to make sure that artefacts are prevented.
Cleaning:
The cuff should only be washed with soapy water and immediately dried off again. The surface of the
microphone pocket is waterproof. Make sure that no moisture penetrates the opening of the microphone
pocket. If this occurs repeatedly, it may result in damage to the microphone.

5Safety notes
5.1 Precautions during operation
Before using the unit, make sure that the medical product consultant has conducted an introduction in
regard to function and safety precautions.
The unit should not be used if there are any doubts as to its being isolated from earth or the suitability of
the power cable.
The supplied power cable meets valid regulations for medical applications.
The unit is not intended for use in wet rooms, outdoors or in areas where there is danger of explosion.
Before its initial operation, the device must be adjusted using the base adjustors at the back to provide
absolute stability.
When the saddle is exchanged, make sure that the screws at the saddle are tightened hard enough so
that the saddle cannot be moved on the saddle pipe.
To move the handle bars and saddle, loosen the clamps and retighten them well afterwards. It is recom-
mended to position the clamps with the levers positioned vertically downward. Secure clamping is en-
sured when the handles are then again turned to this position during the adjustment procedure after
every movement.
The holding straps on the pedals must fit perfectly across the upper side of the shoe and be fastened with
a Velcro strap.
5.2 Safety precautions when operating with other devices
When several devices are coupled, there is a risk that the leakage currents may add up.
Interface RS 232, which can be used for communication with other devices, is isolated to ensure the pa-
tient’s safety.
External devices may only be connected with the interface cables supplied by ergosana.
5.3 Maintenance safety precautions
The device must be turned off and the power plug disconnected before cleaning with liquid cleaning
agents.
Use only standard cleaning agents for plastic surfaces.
The unit may only be opened, repaired and serviced by authorised and trained personnel.
5.4 Interference
The unit meets EMC regulations for medical products to ensure protection against emission and radiation.
Special caution should be taken when using this unit in combination with high-frequency devices.

6Start-up and initial preparation
6.1 Blood pressure recorder for 250
In order to conduct exercise testing correctly, it is of utmost importance to measure physical perform-
ance data and data from the ECG measurement as well as simultaneously measuring and recording blood
pressure data to determine the reaction of the circulatory system to increased exertion.
For this purpose, ergosana has developed an extremely accurate blood pressure measuring system that
is not susceptible to interference. It has been integrated into this ergometer and uses a so-called indirect
method of blood pressure measurement. The Korotkoff sound, which is created by the air being forced
out of the cuff as blood flows through the area of compression, is recorded along with several other im-
portant parameters of critical importance to attain accurate measurement. These measurements are
evaluated in milliseconds by an internal digital evaluation system and shown in the ergometer's display
as systole and diastole. The pulse rate is also determined during measurement and likewise shown in the
display. At the same time as they are shown in the display, the measurements can also be transferred to
a peripheral device such as an ECG or pulmonary function unit for evaluation and recording over an RS
232 interface.
The blood pressure cuff is the measurement sensor for blood pressure. Despite the perfectly functioning
measuring system, it remains critically important that the cuff is placed on the arm correctly and care-
fully.
According to international agreement, the blood pressure should be measured on the left arm, which is
near the heart, as the flow impedance level is lowest there. An exception to this rule is formed by approx.
1 to 2 per cent of test persons on whom the Korotkoff sound cannot be measured due to vascular phe-
nomena. The cuff is placed on the right arm of such patients.
Please note that the cuff's air tube must be fixed in a way that prevents it from dashing against the
ergometer. This is to prevent unnecessary artefacts that might affect the measurement's accuracy.
6.2 Applying the cuff for 250
The microphone is positioned so that it lies on the brachial artery, the largest arm artery. The location of
the microphone in the cuff is marked with a red fabric tag.
The ideal location for the microphone is approx. 2 centimetres above the elbow joint on the inside of the
arm, below the biceps. The cuff must be put on so it is tight and cannot shift out of position during the
movement created during the stress test.
The cuff is inflated rapidly at the start of the measurement. The blood pressure and pulse rate are al-
ready roughly measured during pumping and the inflation pressure is determined.
After the systolic pressure value has been attained, the air is released from the cuff at a rate of 3 mmHg
per heartbeat.
This procedure guarantees approximately equal measuring times despite the rising pulse rate during ex-
ertion.
The blood pressure measurement should not exceed a maximum total length of 45 seconds. One minute
is indicated as the shortest measurement interval. A measurement interval of 2 or 3 minutes is preferable
in most cases.
The blood pressure values are shown in the ergometer's graphic display together with the load and pulse
rate graphs.

7Ergometry
This section describes ergometry with the internal ergometer software.
7.1 Defining the automatic load programs
The following text field appears in the ergometer after it is switched on:
The menu item “Start ergometry” is highlighted with a black bar. This means the item is activated. It is
possible to select an exercise program directly from here and begin ergometry.
Beforehand, however, the five varying exercise programs must be defined according to the examiner’s
needs and wishes. On delivery of the unit, each program is set with normal values which cannot harm the
patient in case they are accidentally activated.
Activate “Define program” with the help of the arrow key .
Confirm with the right “ok” button.

Sana comfort 150 and 250 REHA
Article no.: 2.520064 rev.: b Page 15 of 24
The program selection menu appears.
The exercise programs 1–5 are set according to the parameters of standardised ergometry or according
to individual parameters in such a manner that the correct programs for the different patient groups can
be called up at the touch of a button.
Confirm program 1 with the right button “ok”, and the window containing the settings menu for ergome-
try program no. 1 appears.
Check the existing settings for:
•Type of load (Stage or Ramp)
•Initial load
•Increase in load
•Stage time
•Blood pressure measurement interval (for 250)
•Recovery load
•RR interval 2 min
•RR interval on
Push the “change” button if the settings need to be altered.
The individual parameters then appear one after the other. Select the desired values with the arrow but-
tons and confirm by pressing the “ok” button. The next parameter then appears. The settings menu can
be exited at any time by pressing the “cancel” button.

7.3 Remote operation
7.3.1 Explanation
Remote operation means that the ergometer is externally controlled via the digital RS 232 interface or
USB connector, i.e. all commands for the load and blood pressure measurement intervals are transmitted
from a separate “master unit”.
This type of operation is used primarily when the ECG device has its own ergometry-control program and
when the ergometer and ECG – and possibly other devices such as pulmonary function measuring devices
– can be combined to form an ergometry or pulmonary function measuring station.
In combination with third party units, remote operation is the only approved operation method.
7.3.2 Prerequisites
When the remote operation mode is selected, the unit used (an ECG device or a PC) must be connected
with the ergometer via an interface cable. For our ergometers, this is a type RS 232 interface, which is
isolated to ensure the patient’s safety.
The appropriate baud rate must be selected in the program “Setting” under “Interface”. The appropriate
transmission protocol must then be selected in the same menu under “Instruction Set“. The so-called
"ergoline operating mode" is stored under the setting P 10. Our own transmission protocol is located un-
der “ergosana”.
Information on interface and instruction set can be obtained from the operating data of the master unit.
When the settings have been correctly defined, the ergometer automatically switches to “remote opera-
tion” when the first command comes through over the interface. The ergometry screen is opened in the
display, showing the current load, blood pressure and pulse rate data in both alphanumeric and graphic
forms. The execution of the internal programs is disabled in this operating mode.
Remote operating mode is ended by either pressing the command button “End” or by switching the de-
vice off.

Sana comfort 150 and 250 REHA
Article no.: 2.520064 rev.: b Page 18 of 24
7.4 Training program (option)
The use of the training program requires a pulse signal receiver (Polar system), which is integrated in the
control panel. The receiver can be ordered together with the device or added later on.
The patient wears a transmitter belt, which is positioned on the skin below the chest. The effective radius
of the signals transmitted by the belt and received in the control panel is approx. 70 cm. Please note that
if the skin is dry, contact problems may occur between the belt and the skin at the beginning of the train-
ing. Therefore, if the pulse transmission is unsteady or disturbed, moisten the contact surfaces of the
transmitter belt with contact spray or water.
7.4.1 Training with constant heart rate (Pulse-Steady-State)
A bicycle ergometer training with constant heart rate (pulse-steady-state method) in the individual train-
ing range is a highly efficient and risk-free training method for the cardiopulmonary system. Ask your
physician which is the suitable training heart rate for you. He or she will determine it for you using an
exercise test.
7.4.2 Configuring a training program on the ergometer
To define a training program, select the menu option Define program. Then select the menu option Train-
ing using the arrow keys.
The below settings panel is displayed.
To set or change the parameters in order, press modify.
The first setting defines the Initial load, e.g.
50 watts.
The setting Duration A1 controls the du-
ration of warming-up phase 1, e.g. 1min.
The setting Increase in load controls by
how many watts per minute the load is
increased.
This is the warming-up phase 2.
In special cases, this phase can be lim- ited
in time using the next setting Duration A2.
By default, the warming-up phase 2 is
finished when the target HR is reached.
When the target HR is reached, the load
applied is automatically reduced by 10%.
This measure is to prevent a too great
heart rate increase during the training
phase (TP), which now begins.
The Target HR is set by the next parameter. The setting Duration of training controls the duration of
the training phase (TP). The setting Cool down controls the period of time in which the load is re-
duced to 0 watts after termination of the training phase. The following settings Ask for Po – no/yes,
Ask for HR – no/yes and Ask for weight – no/yes can be viewed when a new training is started and
edited. Editing these parameters can be required when different persons want to use the training pro-
gram.

Warming-up phase 1 with
defined load and time
Starting the Training Program in the Menu Start program > Training.
Please note:
Warming-up Phase 2:
The training heart rate (target HR) should be reached during warming-up phase 2. However, A1 and A2
should together not exceed 5 to 8 minutes. This time is mainly determined by the Po value and the in-
crease in load. From a physiological point of view, an increase in load by 10 watts per minute is recom-
mended for a healthy person but it should not exceed 15 watts/minute even for well trained individuals.
If the period of 5 to 8 minutes is not reached with the settings selected for the first training, the initial
load (Po) should be adjusted.
Training phase:
The effective training is in the training phase. It is important that the body, heart and circulation are
trained but no overload is exerted. The pulse-steady-state program is a very easy means to achieve this.
If the performance decreases by more than 15% within 20 minutes from the start of the training, the
load is too high. In this case, reduce the target HR until an acceptable value is reached. If the perform-
ance decrease is less than 10%, the target HR can be increased.
Adjustment:
During the warming-up phase A1, the Po load can be adjusted in 5-watt steps using the + and - arrow
keys.
During the training phase (TP), the target heart rate (target HR) can be adjusted using the arrow keys.
Load increase by
10 watts/min up to the
target HR or until the set
time has elapsed
Training phase: The load is controlled
by the HR. It should not be more than
10–15% lower at the end than at the
start.
Recovery phase: The
load is reduced to 0
within the set time
Heart rate progress. The HR is
kept on the preset level dur-
ing the training phase (TP).
