Artificial Lungs Prevail
A man survived 48 hours without lungs using an artificial system until he was well enough to receive a double transplant. The landmark procedure took place nearly three years ago, with the patient since developing good function with his donated lungs.
In 2023, the 33-year-old developed flu, pneumonia, and acute respiratory distress syndrome. In severe cases, ARDS is treated with life support to give patients time to fight infection. In this case, however, the patient’s heart stopped, his lungs were melting, and his kidneys had begun to fail. Surgeons at Northwestern Memorial Hospital decided to remove both lungs and use a four-component “total artificial lung” system to drain, filter, and return oxygenated blood to the patient’s heart at a responsive flow rate.
Dr. Ankit Bharat, who designed the system, hopes it can be used in similar cases of severe ARDS, which impacts a portion of the roughly 190,000 US cases per year.
