The iVent 201 is a compact, portable, fully-featured, microprocessor-controlled Ventilator offering the versatility and capability of larger and costlier ventilators. A turbine-powered air source and a rechargeable internal battery provide freedom from wall air and power outlets. An intuitive turn-and-click control knob, quick-choice pushbuttons, and a bright, well organized, easy-to-read screen allow rapid control and continuous real-time monitoring of patient ventilation. Alarm settings are fully adjustable. Optional Waveform and Diagnostic Software package displays pressure and flow waveform data, loops, trends, and logged totals in a full array of graphical and numerical modes. The iVent 201 supports many modes: • Assist/Control • Volume Controlled A/C • Pressure Controlled A/C • Synchronized Intermittent Mandatory Ventilation (SIMV) • Volume Controlled SIMV (Vctrl SIMV) • Pressure Controlled SIMV (Pctrl SIMV) • Continuous Positive Airway Pressure (CPAP) • Pressure Support Ventilation (PSV) In addition, the iVent201 has these advanced features: • Rise time is adjustable • Preset Parameters by Patient Weight enables quick setup • Adaptive Peak Flow can determine and deliver Inspiratory Peak Flow Rate according to a target mandatory tidal volume, maintaining a 1:2 I:E ratio • Adaptive I-Time allows the Ventilator to determine and deliver a respiratory cycle time to sustain a 1:2 I:E ratio • The iVent 201's Adaptive Bi-Level feature enables leak-tolerance for facemask ventilation or other specialized high-leak tube ventilation • Easy Exhale™ is an advanced PEEP mode designed to reduce expiratory work of breathing • Firmware is upgradeable via a PC connection • The iVent 201 is designed to operate according to specifications in any physical orientation – such as during transport use.
