Elon Musk and his engineers seem capable of achieving the impossible. From landing rockets to “Ludicrous Mode”, they have destroyed the walls between thought and production. That is why we’re awestruck at Tesla’s ventilator design team. If you ever needed a proper example of how fuel injection works, this would be it. Using parts from the Model 3, their apparatus mixes hospital oxygen to a desired pressure, flow, and saturation. An O2 sensor and a mass airflow meter in the exhaust send commands back to the intake to constantly make adjustments. Although it looks complicated on the bench, this design is poised to change the world of Respiratory Therapy. Well done to all involved!
