• Subjects who are involved in the clinical trial are already mechanically ventilated on traditional standard commercial ventilator. Baseline measurements (T0) will be taken from each patient before being transferred to EZVent ventilator. The following measurements will be taken: Vital Signs and hemodynamics (heart rate, blood pressure, temperature, Respiratory rate), Chest X-ray, Arterial blood gases as well as the ventilator mode parameters (dependent on each mode) and lung mechanics parameters (Peak, Plateau, Mean Airway Pressure, Tidal Volume, Airway Resistance and Static Compliance).
• After taking the baseline measurements, subjects will be disconnected from their traditional standard ventilator and immediately connected to EZVent using the same previous original setting.
• After 60 & 120 minutes of ventilation on EZVent (T1&T2) respectively, the same measurement will be taken (Vital signs and Hemodynamics will be continuously monitored and recorded every five minutes).

EZVent Ventilator System is designed for respiratory support in hospitalized mechanical ventilated patients. The Ventilator is designed to be used for adults patients. It is designed to be a stationary product suitable for service in hospitals, critical care situations to provide continuous positive pres- sure respiratory support to the patient. The ventilator met EDA, ISO 80601-2-12 requirements on essential performance of critical care ventilator and other applicable international standards.
