Abuse me for I will not care...

Abuse me for I will not care. Curse me when I stray from fair. Brute force won't put me in my place. Smooth and even wins the race. Envy colors where I rest. No sandy beaches for the best. What is it?

Iron lung

In 1927, the first iron lung (electric respirator) was installed at Bellevue hospital in New York for the post war polio epidemic. The first iron lung was developed at Harvard University by Phillip Drinker and Louis Agassiz Shaw built with two vacuum cleaners. The iron lung is a negative pressure machine which surrounds the patient's body except for the head, and alternates a negative atmospheric pressure with the ambient one, resulting in rhythmic expansion of the chest cage (and thus inhalation) in response to the negative extra thoracic pressure. During periods of ambient extrathoracic pressure, the lungs deflate. This type of machine is rarely used today.[Image: Early Drinker respirator prototype, 1928]
