Paul Alexander contracted polio in 1952 when he was six, leaving him paralysed from the neck down.
In 1952, when he became ill, doctors in his hometown of Dallas operated on him, saving his life. But polio meant his body was no longer able to breathe on his own.
The answer was to place him in a so-called iron lung - a metal cylinder enclosing his body up to his neck.
The lung, which he called his “old iron horse”, allowed him to breathe. Bellows sucked air out of the cylinder, forcing his lungs to expand and take in air. When the air was let back in, the same process in reverse made his lungs deflate.
He would go on to earn a law degree - and practise law - as well as publish a memoir.

Tl:dr version … Yes, because we don’t build iron lungs anymore. “Instead, they would likely use mouth intermittent positive pressure ventilation.”
Ventilators are positive pressure, pushing air into the lungs which is good for those with breathing issues.
Irons lungs are negative pressure because polio patients don’t have a problem with their lungs … polio has invaded their brain and spinal cord and killed control over their chest muscles and diaphram. Negative pressure forces their chest to rise and fall, making them “breathe”.
The article is worth reading.
