ABU v01

During the first wave of the Covid-19 pandemic, PBL contributed to the emergency by leveraging its skills and know-how to design and manufacture a cheap but effective mechanical ventilator: the ABU v01.  The entire proces that includes also the CE mark, took less than less than 2 months.


ABU v01 is a CE-marked medical device that transforms the traditional AMBU device into a real Assist-Control Ventilator (ACV) and Pressure-Support Ventilator (PSV), for ICU, through the implementation of advanced flow and pressure sensors and a high-precision feedback system. ABU can be used for both invasive and non-invasive (NIV) ventilation. The device is able to automate the ventilation process by operating the traditional AMBU system.

ABU v01 allows users to electronically monitor and control the following functions:

  • PEEP pressure (i.e., minimum positive pressure at end of expiration)
  • Maximum Peak Pressure
  • Airflow
  • Breathing Frequency
  • Peak Inspiratory Pressure (PIP)
  • Plateau Pressure
  • Support Pressure (for assisted mode)
  • Inspiratory and expiratory time ratio
  • FiO2 (21%, 45% and 99%). Other ranges can be obtained with oxygen blenders
  • Backup Time

In addition, ABU v01 offers:

  • Battery autonomy: 1,30 h.
  • Touchscreen 7’’ interface( (touch gloves on)
  • Connection to centralized alarm system
  • Data trasnfer
