Spurred by the demands of the COVID-19 pandemic, researchers at Princeton and Google are applying mechanical engineering and artificial intelligence in an effort to increase the availability and effectiveness of ventilation treatments worldwide. Ventilators and their support equipment are lifesaving technologies, but they are also expensive and complex devices that require expert attention from doctors and other highly trained medical workers. The devices must be carefully calibrated and monitored to ensure they are meeting a range of parameters — pressure, volume, breath rate — tuned to each individual patient. Often, these measures change during treatment, requiring further tuning. To read the full story.
