Using SYMBIOLINE Professional

Precautions for use ?

As a rule, SYMBIOLINE Professional is suitable for any patient. However, we advise against using it for:
- Paranoid or schizophrenic patients, highly depressive patients, and obsessional patients.
- Very young children (they are not able to understand and act upon breathing movements)
- Pacemaker patients

SYMBIOLINE : Objectives and limitations ?

  • Both professional users and patients should be fully aware of the objectives and the limitations of our technology.
  • SYMBIOLINE is an ideal tool for therapeutic approaches that choose a holistic, multidimensional strategy to address stress and anxiety.
  • SYMBIOLINE cannot be used as an alternative to a prescribed medical treatment. Besides, SYMBIOLINE is not a substitute for proper medical care if the patient’s health status requires it.
  • Better results will be obtained if the user is guided by a healthcare professional when using SYMBIOLINE. Results are also better if SYMBIOLINE is used in conjunction with other techniques such as psychotherapies, stress management training, physiotherapeutic rehabilitation, relaxation, pharmacological treatments, or more specific treatments.
  • Patient motivation, commitment, and compliance are crucial to ensure success.

What should therapists do if patients experience difficulty in reaching a state of cardiac coherence ?

Therapists should comfort patients if they do not manage to reach a state of full cardiac coherence.
  • It is recommended to tell patients that they need to keep trying to reach a state of cardiac coherence. Patients should be told that by striving to reach it, they will improve their self-control and gradually obtain significant results.
  • It is essential to motivate the patient through regular practice. It is the only way of making progress. Through practice, the patient will learn to deal with the negative effects of stress in everyday life.
  • Patients should be comforted and encouraged to carry on, even though they do not reach cardiac coherence immediately: they should be told that their heart rate variability is perfectly normal.
  • Patients should be advised that what counts most is their ability to better adapt to stressful situations. Adaptability is the tool that will help them fight the negative effects of emotions on their health.

How can results be improved ?

Stress and emotion management techniques, breathing control techniques, and relaxation techniques can help patients achieve cardiac coherence. Therapists should help patients master these techniques in order to improve cardiac coherence.
Patients can also use these techniques on their own, for example with SYMBIOLINE’s relaxation exercises. Reading self-help guides in which these techniques are described is also very useful.

Signal - Signal quality

The message “Module not recognized” appears on the screen

Make sure that you have properly connected the ECG sensor to your PC (the sensor’s black case should be connected to the PC by the USB cable).

The ECG signal is blurred or poor

1.If your laptop or your desktop is connected to power supply, ensure that the plug is plugged into an outlet that is properly earthed. If the outlet is not earthed, the signal may be affected by interference.

2. Check that you have properly fastened the 3 bracelets around your wrists and that the conducting band is against your skin. Check that you have fastened 2 bracelets on your right wrist, and 1 bracelet only on your left wrist.

3. Make sure that the cable with the red mark (it is the earthing cable) is properly connected on your right wrist.

4. Wait until your electrode bracelets polarize properly: this may take 2 to 3 minutes, then the signal’s quality become optimal. The explanation for this is that your electrical cardiac signal may need some time to stabilize.

5. Make sure that no other PC is operating close to your SYMBIOLINE devices (for example, you may have a laptop in the vicinity of your desktop). This may cause electromagnetic interference. Similarly, a mobile phone that is turned on, an electrical adapter, or any other electrical device may cause interference and affect the performance of the SYMBIOLINE solution.

6. If the signal is still weak or blurred, test the sensor on another person. Skin conductance can vary: some people have better skin conductance than others.

7. Clean the bracelets by rinsing them under the faucet. DO NOT USE DETERGENT or any other cleaning product.

8. Carefully follow the instructions for use. In particular, do not move your arms or your hands whilst using SYMBIOLINE.

9. If above instructions do not help, unplug all the cables. Start over and execute the installation procedure again, carefully following the instructions in the user’s guide.

When using SYMBIOLINE’s 3D video exercises, the heart rate indicator (above right) displays “NA”, or values that seem erroneous (for example, 247 bpm)

This may be due to two causes:

1. The signal is poor—bracelets have not been installed correctly, or the patient’s forearms are tensed or moving, etc.

2. Your PC configuration is not suitable for using SYMBIOLINE. In particular, your computer’s RAM capabilities may not be sufficient to allow SYMBIOLINE’s measurement engine to analyze the patient’s heart rate variability and communicate with the 3D video interface simultaneously.
Solution: upgrade your graphics card, or add RAM to your computer.

Please note that if erroneous values appear very briefly, this will not prevent SYMBIOLINE from delivering very accurate results—SYMBIOLINE’s measurement engine includes an intelligent, patented filtering device which corrects these errors in real time.

Accessories

Bracelets are dirty

Rinse the bracelets under a faucet. DO NOT use detergents or any other cleaning agent: this could cause critical damage to the bracelets.

A bracelet has been lost or damaged

It is recommended to purchase a new set of bracelets from SYMBIOFI’s E-Store.

The ECG bundle has been damaged, or a cable has been severed

It is recommended to purchase a new set of ECG cables from SYMBIOFI’s E-Store.

Is it possible to use electrodes instead of SYMBIOLINE’s standard bracelets?

YES, of course. SYMBIOLINE’s built-in modularity allows to use disposable self-sticking electrodes (with the proviso that their diameter is 4mm.)

Is it recommended to use additional products to improve skin contact and signal quality?

We strongly recommend not to use any additional products. Our bracelets have been designed to be used without any additional accessories or products.
