Weighing 22 pounds, the iVent201, with its self-contained turbine and internal battery, is one of the only true transportable critical care ventilators. The iVent201 Adaptive Bi-Level option is designed to improve patient comfort during mask ventilation. The use of an exhalation valve reduces CO2 rebreathing and therefore enhances patient comfort. In addition, extended rise time control and termination of the breath based on flow or l-time improves patient synchronization. The iVent201, from VersaMed, can be tailored for multiple applications from intensive care to the ER and home care use. The iVent201 provides a single solution for both mask and intubated ventilation.
