Artificial lungs in a backpack may free people with lung failure


Key points from article :

Usual treatment is a large machine that pumps their blood through a gas exchanger to provide oxygen and remove carbon dioxide.

Artificial lungs have proven harder than making a mechanical heart.

Lungs contain a fabulously convoluted network of branching air sacs to allow gases to diffuse in and out of the blood.

One device is small and light enough to be carried in a backpack – but still needs a gas cylinder.

Another device under development runs off the air in a room using extremely thin channels formed by polymer membranes.
