The Philips Respironics Trilogy 202 is both a volume-control & pressure-control ventilator for invasive and noninvasive ventilation. This ventilator has versatile breath delivery and setup options which provide greater continuity of care. The Trilogy 202 has the unique ability to compensate for leaks in both pressure and volume control modes, using simpler passive circuits may support significant time and cost savings. The Auto-Trak algorithm improves patient-ventilator synchrony by adjusting to changing breathing patterns and dynamic leaks. Also the Trilogy 202 allows freedom of movement with a 3-hour internal battery.
