Global race to make ventilators -------------------------------------- Inventors, academics, carmakers and aerospace firms are rushing to build hundreds of thousands of ventilators to help save the lives of people with Coronavirus- related breathing difficulties MECHANICAL VENTILATOR Ventilator unit: Pushes air into lungs, replicating normal breathing when disease causes lungs to fail. Patient must be heavily sedated Carbon dioxide flow from patient Oxygen flow to patient Humidifier Matches air to body temperature and adds moisture Tube inserted into windpipe Medication relaxes respiratory muscles so breathing can be fully regulated by machine NON-INVASIVE VENTILATOR Face mask covers nose and mouth Continuous Positive Airway Pressure (CPAP) device delivers oxygen to lungs without need for ventilator Mercedes F1 is offering engineering expertise to University College London to build up to 1,000 CPAP machines per day -------------------------------------- Sources: AP, BBC, UCL Picture: UCL © GRAPHIC NEWS
