  1. Results are presented as the different objective tasks success rate, expressed as the percentage of successful attempts. ICU’s physicians with mechanical ventilation’s knowledge had to complete 11 specific tasks of variable clinical importance for each ventilator, 4 mainly dedicated to monitoring and 7 to setting. Overall provides results of the entire bunch of test (first value), or after powering on/switching off tasks exclusion (second value)
  2. Among all ventilators, our reference device the Avea had the better success rate. In between our comparison of the six ventilators, Covidien PB980 had the better results and the Servo-U the worst. A minority of users could power on Servo-U and always over the predefined 120 s time range. Settings reading represented the more difficult task, whatever the device, while their terminology was highly different from one device to the other
