The Philips Respironics Trilogy 200 portable ventilator is lightweight and easy-to-use. The Trilogy 200 was designed for the home, hospital, and alternative care sites to provide invasive and noninvasive ventilator support for a wide range of pediatric and adult patients. The Trilogy 200 has all the features of the 100, plus extra triggering sensitivity utilizing a proximal flow sensor. The extra triggering sensitivity decreases the work of breathing and provides increased comfort, better ventilation and improved patient/ventilator synchrony.
