4.7 Conducting a session

To conduct a SIMEOX session, the patient must be settled comfortably.

The patient can change positions when using the device (on their stomach, on their back, semi-seated, on their side) in order to maximise drainage from all areas of the lung. SIMEOX does not act during the inspiratory phase, SIMEOX acts only during the expiratory phase

The patient is relaxed The patient begins by slowly inspiring through the

nose followed by an inspiratory pause. When the patient is ready to release air from his/

her lungs, he/she places the mouthpiece in his/ her mouth and press the remote control button (or the GO button on the front) to start the SIMEOX vibratory signal.

The mouthpiece is positioned in such a way that it is an extension of the trachea.

The mouthpiece is placed on the tongue, in such

a way that the tongue does not obstruct the mouthpiece during activation of the signal during relaxed expiration by the patient.

The GO button must be pressed throughout the expiratory phase.

The patient lets the device take control during his/ her relaxed expiration without opposition and feels the vibrations in his/her thorax.

Repeat the steps above as many times as necessary. A typical SIMEOX session consists of 4 to 5 cycles with a pause of 45 seconds between each cycle to be adjusted according to the needs and condition of the patient.

The patient only coughs to expectorate. If the cough is triggered prematurely, it must be controlled.

After a 20- to 30-minute session, the patient is drained. He/ she coughs naturally at the end of the session and/or at a later stage.

Reminder: in order to ensure that the device is optimally effective, training in the use of SIMEOX is recommended. Contact PHYSIO-ASSIST, your physiotherapist or your referring doctor for this training.

The mouthpiece is badly positioned if the vibrations are felt in the mouth and not in the thorax. An expiration that is too long or forced risks to prematurely trigger a cough, as does an inspiration that is too strong or violent

If lights 1 to 5 are illuminated: the transmission quality of the vibratory signal is optimal

If the red lights illuminate, the expiration must be stopped by releasing the remote control button or removing the mouthpiece.
