iron lungs use something called negative pressure (as opposed to positive pressure) to help air into the lungs of patients because they cannot use their own muscles.
this means that the big “tank” you see fits around the chest of the person, who lays inside of it, like a coffin. their head stays outside the device. subatmospheric pressure is exerted inside the device which means pressure is LOWERED inside the sealed tank. this causes there to be a lower pressue in the TANK than INSIDE the lungs which makes the chest wall expand, inhaling. the pressure is then increased, which causes exhalation. essentially an exolung.
another symptom of ventilation other that psychological distress is cardiac destruction. many people do not think of the heart and lungs as inherently linked organs, but they are. the pulmonary artery goes directly from the heart to the lungs (for blood to be oxygenated) and the pulmonary veins go directly back from the lungs to the heart (to be pushed into the body’s peripheral vascular system and circulated in the body). which is to say, any stress on the resporatory system does irreversible damage to the cardiac system.
these things include: hemoptysis (bloody foam sputum), fluid gathering in the lungs as the heart fails because the body cannot pump out fluid from the weak lungs, children essentially drowning to death in their own fluids, pressure sores all over the body from lack of oxygenated tissue as they have to remain laying in one position (essentially decaying flesh on a living person), slowed cognition and mental processes because of lack of oxygenation to the brain, disturbed growth processes, post traumatic stress disorder… among other things.
so yes. these were torturous subquality of life devices of pure human desperation. they were invented in 1928 by Philip Drinker and revamped several times before the 40s. they were used to quell the tragic and horrendous cries of parents whose children were suffocating to death with no other hope but to be suspended in what looks like a medieval device of agony.
people did all THAT, endured all THAT, to get to the point where research and knowledge was far along enough to create vaccines.
it is pure selfish ignorance that prevents anyone from vaccinating a child and it should be a reportable offense as child abuse if a parent does not vaccinate a child.
