I feel bad making fun of it as a layman as it's slightly unscientific kibbitzing like this but I swear in the future they're gonna be making fun of us for blowing people's lungs up like a balloon and wondering why it's not controlling a respiratory illness. I'm not a doctor but I did software engineering on a medical ventilator for a while. I think we have a pretty good idea of what we're trying to do and it's more sophisticated than "blowing people's lungs up like a balloon." Modern ventilators are very safe and can be configured to be effective. Part of the reason for this is that the FDA makes sure the manufacturers comply with actual safety standards. It was a real pain in the rear end, I recall, because of things like bio-compatibility testing. There were at least 3 or 4 thousand different individual requirements we derived from the relevant standards documents. There are more standards for ICU ventilators than there were for our intended usage. The whole purpose of gas delivery in this case is to keep your alveoli from collapsing and sticking together from being filled with your body fluid. PEEP(Positive End-Expiratory Pressure) or CPAP(Constant Positive Airway Pressure) are often used to do this. A lot of the issue comes from maintaining enough gas diffusion in the pulmonary system to eliminate CO2 and take in oxygen. When your alveoli are collapsed, this is very difficult. If you are having trouble breathing naturally, a ventilator can additionally support your breathing by providing additional flow, making it easier for you to inflate your lungs. This can help recruit more alveoli for gas diffusion than your diaphragm can alone. Modern ventilators can trigger this inflow by detecting when you're trying to take a breath(Flow Triggering). Part of the problem is less our understanding of the pulmonary system and more that a human has to constantly monitor the patient, make adjustments to the ventilator, and continue monitoring the patient. There are a lot of ventilator-dependent patients to be monitored, and I don't know how many hospitals have enough Pulmonary Specialists and Respiratory Therapists to manage this many patients. The patient conditions probably change too quickly for the condition to be managed effectively once you're ventilator-dependent.

The patient conditions probably change too quickly for the condition to be managed effectively once you're ventilator-dependent. They're very sophisticated pieces of equipment able to treat a variety of pulmonary deficits but the SARS associated with COVID 19 is so dramatic they get turned up to 11. If someone finds a therapy that can limit their use or get kept at the levels associated with better ventilator outcomes they'll absolutely look back at COVID 19 like we're blowing lungs up like balloons.

I work for a respiratory simulation company and am in agreement with Sex Skeleton's take. The process of ventilating a patient varies greatly based on the patient's condition and physiology, and vast amounts of research go into fine-tuning those details over time. Discussions about how specifically to handle COVID-19 are taking place all day, every day, involving the entire respiratory health community. The amount of RT training going on right now is impressive as well, from diagnostics to vent maintenance to treatment. Of course, if you're sick and need mechanical ventilation, you have to both know you're sick and have access to a vent. There is no case where treatment later is better than prevention and early treatment, so the lack of testing and equipment is a major fuckup.

Azathoth posted:Leaded gas alone is a poor fit with the timeline, but it's easy to forget just how many other chemicals were sloshing around in our drinking water and floating in the air during that whole time. Like, things aren't great now, but holy poo poo were they bad back then and I don't think we even really understand just how bad it was. yeah, and even for those who grew up after leaded gasoline was fazed out, we still have likely had much more exposure than those who were born after 2000 or even later. One of the craziest facts to come out of the Flint water crisis, was that as scary and dangerous as the spike in lead exposure was, was that it still wasn't as bad as the "normal" exposure level just a few years earlier. And this isn't a problem particular to the USA. Lead exposure rates have basically moved in the same, improved direction the world over.

Exposure to lead paint is still a blight across a lot of the poorer areas of the US and has stunted the development of thousands of children. The housing stock is so old that peeling lead paint is all over the place and toddlers etc do nibble on them and put them in their mouth since they taste slightly sweet. Due to the lead. Which is poisoning them. There is no proper federal program to tackle the crisis and lol at the idea of slum landlords doing it. Generally it only happens when an area gets gentrified and the existing renters and homeowners get priced out and turfed out.

Aviation gasoline is still leaded. Bringing this up around pilots is like bringing up Poe’s orangutang around scholars of literature. One facility in Leeds makes the whole world’s supply of tetraethyl lead.

Asbestos is pretty "safe" unless you work with it in industry, construction or demolition. Even a clueless home owner is unlikely to develop a life long exposure to the fibres unless they are drilling holes through asbestos elements every day. Lead on the other hand used to constantly affect everyone to some degree.

I haven't noticed any real controversy among the pilots I know. Everyone's attitude is "well, yeah, but what are you gonna do? Not fly? Pfff" I do draw the line at the old fart method of checking the fuel level by sticking my finger in the gas tank, though. "One knuckle, that's 3 hours of flying, we're good to go." No thanks

One of my first jobs in my 20s was bench testing gas powered water pumps by unscrewing the carburator bowl and replacing it with one that had a tubing nipple welded onto it, connected to a can of LL100. And then switch the original bowl back in. I often wonder how many brain cells I lost doing that 35 times a day for two years. I mean, I still post here so it had to be significant

MRC48B posted:IIRC the last time TEL came up someone mentioned there's several viable alternatives to Leaded avgas, but since the epa got basically gutted, the FAA cant be bothered to force a change. ehhhhhh it depends on your definition of "viable." forcing a change would entirely kill general aviation nationwide due to the cost. like, the best solution would be to invent a diesel engine that is a bolt-in replacement for an O-320 (as used in tons of little Cessnas and Pipers and the like), then just swap all the old gas engines out and start running your planes on jet fuel, which diesel engines can burn. it's much less toxic and far more broadly available. but that would require that you invent the engine, which is no small feat, and then have the FAA test and certify its installation in every single airplane, and then have every small airplane owner buy a new engine (which is gonna be like 2/3 the cost of a used plane) and that's just not tenable. as far as inventing some additive that makes planes run on unleaded fuel -- there are additives that can do that in some cases, but again you need an extensive safety testing and certification program to verify that the change won't cause any safety issues. only a few aircraft/engine combinations have been certified to work that way (the Cessna 150 and the O-200, for example). the risk of having the new fuel corrode a seal or blow up your engine, likely resulting in injury or death, is seen as unacceptably great compared to the relatively tiny impact of lead pollution. like it's worth noting that the total annual consumption of 100LL avgas in the USA is equal to about six hours of motor vehicle gasoline usage. not even diesel for trucking, just gasoline. it's literally a drop in the bucket Sagebrush fucked around with this message at 23:10 on May 12, 2020 |
