5.2. SMART ASSIST
If the nasal cannula is not well placed, its holes are too small or the patient
breathes through the mouth, any device of pulsed oxygen therapy
(economizer or concentrator) cannot detect inspiratory effort and not send
pulses of O
2
. It is essential to educate the patient on the need to use
appropriate cannula, take them in place and breathe through the nose. The
innovative Smart Assist system (patent pending) is designed to assist in
this education.
Smart Assist analyses the respiratory time. If it does not detect inspiratory
effort during a time abnormally high, it warns the patient by sending a train
of small pulses of O
2
, which are not bothersome. If it does not still detect
inspiratory effort, sends a second train of longer pulses. If, despite these 2
warnings, the inspiratory effort remains undetected, it activates
disconnection/apnea alarm.

This functionality can be enabled or disabled. OXYMO is factory supplied with
the Smart Assist deactivated.
5.3. SMART TRIGGER
A) The vacuum is not detected through an electro-mechanical pressure
switch, but in a high sensitivity pressure sensor. This permits to deliver
oxygen very early, so that less bolus is required to achieve the same
physiological effect. If an O
2
cylinder is used, more O
2
it saved and
increases patient autonomy.
B) The trigger level is very low and adjustable. This allows to detect weak
inspirations and to better adapt to each patient. Smart Trigger introduces
an analysis algorithm to avoid false triggering.
