Oxygen toxicity exists and ideally you give just enough oxygen concentration to keep PaO2 at minimum adequate levels in order to stave it off but sometime the oxygen concentration that is necessary is 100% (and even that might not work). Here is the money quote:

Life threatening hypoxia must always be relieved even if this requires the use of 100% oxygen for prolonged periods of time.
 

Suffering side effects from oxygen toxicity is bad, but being dead is even worse. Sometimes in medicine you have no good choices and can only choose the lesser of two evils.

No, we switched sides in WW2. In WW1, we waited it out while the King and his allies argued for a German alliance and the other elites argued for an Anglo-French one. Story of our lives, really. Entered the war in 1916 because the hour was late and we wanted Transylvania. The total neutrality crowd was also strong. Austria-Hungary as it was then was headed for the trashbin either way, because of demographics and internal nationalism. We in the Kingdom owed A-H and Hungary nothing and work hard at increasing the number of people who think that, because the people who do think they owe you are dangerous.



I would disagree on the persecution. This does not mean that it did not happen or that we did not sometimes adopt the same policies (for Romanianization) that our neighbors did (we learned a lot from Kossuth early on and his Magyarization). Anti-Hungarian prejudice existed, and of course the self-governing nation system had to disappear. Other than having to choose between citizenships and swearing an oath of allegiance to the state in order to maintain a role in public administration (the optants), there was only one other policy - the land reform which involved expropriation of the large landowners (the "Grof") with 100 tons of gold awarded in neutral arbitration in Paris, which led to land in Transylvania being allotted to 369 thousand Romanian and 87 thousand Hungarian peasants (in addition to being the majority, we were also the most rural, and the poorest). This was a case of disparate impact you could say, but land reform took place everywhere else in Romania as well at the time, but the expropriated ones where Romanians and Greeks, as well as the older land reform of the 1860s, which targeted the Church.

We too had our fascists and attitudes hardened after the Diktate of Vienna, when our ally, Nazi Germany, gave our ally Hungary Northern Transylvania, where followed a quite brutal period for all involved on the ground. We did not have much love for either afterwards and switching sides was the whole point of the coup which replaced Antonescu (whom we shot, shamefully). But the story of the evolution of the population levels for the minority, even under a totalitarian state which moved hundreds of thousands of people on a developmental whim, the maintenance of its concentration and language in the heart of the country in the three central counties (urbanization policies meant that the cities everywhere rapidly increased their Romanian proportions) show that the government was at least careful and its rhetoric emphasized the maintenance of language and culture for minorities. Neither do our other minorities claim that they were especially targeted for persecution, other than the general awfulness and arbitrariness of the Communist period which hit all of us. This is a book written by Hungarians and published by our Institute for the Study of minorities - The Magyar Minority in the Communist Period. Maybe you can find it in Hungarian. I would not be surprised if it was published that way. https://www.academia.edu/2574842/Minoritatea_maghiar%C4%83_%C3%AEn_perioada_comunist%C4%83

The evolution since, with the extraordinary permission for the creation of an ethnic party and its continuous presence in government coalition with high level positions does not imply love, but neither does it show marginalization. On the contrary, the Hungarians have been kingmakers in Romanian politics far out of proportion to their numbers.

One would have appreciated the chance to help build out Transylvania, but I would remind you that another word for serfdom there is "rumanie". The status of the Romanians as a "tolerated nation" not equal to the three other nations, as affirmed in the documents of the era, made it quite hard to develop in ways similar to the others. No Romanians in towns, no stone buildings, no political rights unless one turned Catholic or protestant (which then led to assimilation). Even today, the ideal Transylvanian home is the Saxon fortified dwelling. The famously narrow minded and rigid Ardelean (internal prejudice, my Southerners are supposedly all gregarious thieves) is what you get after a few centuries of boiling off the assimilable. The Romanians there have always looked towards Vienna for amelioration of their status and to play off against Budapest. They finally got the right to an Orthodox bishop by 1759, freedom from serfdom by the early 19th century. However, it was only in 1902 that the first Romanian cathedral was built in Sibiu (Hermannstadt) (mind you, a multi-ethnic team effort). As for being there for hundreds of years, I would remind you that such a nice place was hardly empty when you arrived. But even that is a ethnic group mistake. Most of the people in Transylvania, regardless of ethnicity, derived from the people already there, and ethnic sorting took place after, aside from a small number of mobile elites and well known colonization policies for frontier defense (involving Germans).

As for our xenophobia, it is quite an odd one indeed - with guaranteed representation in Parliament for all historical minorities, with a re-elected German President, a Half-Hungarian Prime Minister right now, our Half-Hungarian first European Commissioner, a Turkic Muslim PM candidate that almost made confirmation (Klaus rejected her) and a wide array of high officials who have been German, Hungarian, Jewish, Armenian, Gypsy, even the odd Arab (no Russians, I'll give you that), including those in critical functions like head of the intelligence service and head of the anti-corruption directorate. And an allegedly xenophobic left-party (PSD) which instructed its voters to vote for the Hungarian party so it can make the 5% cut-off for being in the European Parliament and to sign lists for Kelemen Hunor to be able to run as President (thousands of signatures in counties with fewer than 10 Hungarians). And with no appeal to quotas or distributive justice, only cold hard politics and one's personal capacity for sociopathy and manipulation that makes a "good" politician. Not to mention how early on we allowed double citizenship (as opposed to your other neighbors), which turned Hungarian politicians' electioneering here into a perennial irritant and tightrope act.

Mind you, I do not much care for the issue one way or the other. The Romanians in Transylvania are the ones who express gratitude for Austrian administrative competency and an appreciation of the Hungarians and their qualities every chance they get. But its their grandparents who got the shit kicked out of them in 1939 and who got new documents from the Hungarians military administration calling Stefan Istvan, so they started giving their kids the freakiest possible names to stave off Magyarization (I've heard Romeliu, Flavius). They remember that too, and getting stuck with them in some sort of autonomous arrangement is not something conducive to peace.

Talk about a problem with an easy solution. How many airliner flights to Mexico City would it take? Not that many, I wager.

Everywhere in the world must be made to be like everywhere else.

Also, there is also a distinct countryside accent, often typified by dropping, for example, the “L” in a word like bolt (English: store) — so it sound like boat.

 

The dubbing craze is catching up in Romania. We used subtitles exclusively until a few years ago. Now, they are dubbing movies for children (which is very bad for any incipient English language skills).
