This shows the confined bag valve mask cycling through inhalation / exhalation
This video shows the results of our first week of intensive working The Ambu or bag valve mask is confined within a rigid perspex box. This box can be pressurised from a 4 bar line. When it is pressurised, the Ambu compresses, providing an inhalation. When the pressure is switched off, the Ambu re-inflates.
We are open to all offers of collaboration that will enhance the national effort.
