A small enough artificial lung can be packed in a backpack, and sheep tests have shown that it works. This is a device that can save patients with lung failure, and most patients still rely on larger equipment. Now, the new equipment still needs to be carried with an oxygen tank, but equipment without an oxygen tank is also being tested. Patients with lung failure usually need to connect a pump that delivers blood to a gas exchanger to provide oxygen and carry away carbon dioxide, but this often limits them to bed. The longer you stay in bed, the weaker your muscles will be and the harder it will be to recover. In order to avoid this vicious circle, those wealthy people will walk around the hospital with help, but it is also very difficult, because the ventilator has a variety of long and heavy pipes. After the swine flu in 2009, many patients who depended on this therapy ended their lives, and for this reason, other better options began to emerge. Artificial lungs provide an expedient measure for patients who are recovering from a severe lung infection or who are waiting for a lung transplant. However, those with permanent lung damage still need long-term solutions. However, making artificial lungs is more difficult than mechanical heart. “The heart is just a pump,†says William Federspiel of the University of Pittsburgh, while the lungs contain an extremely complex network of branching balloons that allow gas to enter or remove blood. “The ability of the lungs to exchange gases is very powerful, and there is currently no artificial technology that is close to its efficiency.†Breathing more easily, a backpack can do this.
