摘要：
The invention is related to a device and method for monitoring respiration movements in mechanical ventilation in order to provide a non-pneumatic triggering for achieving patient-ventilator svnchronv and continuous measurement of efective tidal volumes. The method is based on noninvasive measuring the curvature of the patients torso surface using a single LPG (Long Period Grating) fiber-optic sensor (31) attached to a surface of the torso in an area having high stiffness of the underlving tissue, such as the area of the lower ribs close to the sternum.Pronalazak se odnosi na uređaj i postupak za praćenje zapremine vazduha pri disanju u mehaničkoj ventilaciji, kako bi se omogućila nepneumatska aktivacija za postizanje sinhronizacije između pacijenta i ventilatora i kontinualno merenje disajne zapremine. Postupak se zasniva na neinvazivnom merenju zakrivljenosti povrpšne torza pacijenta korišćenjem jednog fiber-optičkog senzora (31) baziranog na rešetkama dugih perioda upisanih u vlakno (LPG - Long Period Grating) i postavljenog na povrpganu torza u zoni veće čvrstine potkožnog tkiva, kao što je zona donjih rebara u blizini sternuma.
