which is to say, any stress on the resporatory system does irreversible damage to the cardiac system. 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). many people do not think of the heart and lungs as inherently linked organs, but they are. essentially an exolung.Īnother symptom of ventilation other that psychological distress is cardiac destruction. the pressure is then increased, which causes exhalation. this causes there to be a lower pressue in the TANK than INSIDE the lungs which makes the chest wall expand, inhaling. subatmospheric pressure is exerted inside the device which means pressure is LOWERED inside the sealed tank. This means that the big “tank” you see fits around the chest of the person, who lays inside of it, like a coffin. 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. So even someone “lucky” like that person up-thread’s grandfather, might have severe complications later on, even if they survive it initially! In my grandmother’s case, her lungs already weren’t great from the first time around, and she ended up going into cardiac arrest in and had to be on a ventilator for a year, and couldn’t walk anymore - she’d been able to use crutches and go short distances before that - this would have been in the early 80s, so a good 35-40 years after she first had polio.
*Because we started fucking vaccinating people for aįucking REASON, and it’s not a problem if you’re not getting polio in It’s not super well-understood* but basically, in a certain percentage of people, decades after the initial infection - assuming you survived, that is - you start having more paralysis and more fatigue and more weakness. My maternal grandmother spent over a year in an iron lung when she was 17 - she and her little sister got sick in the same week.
