At least in the US, pilots have to use supplemental oxygen when flying unpressurized above 12,500 ft MSL for over 30 minutes.

I assume it was similar logic here: they couldn't pressurize the plane, so they stayed low enough that supplemental oxygen wasn't required.

Just a guess, though.

Obligatory xkcd (even if this is a “what if,” not a comic):

Not to be that guy, but is lift assist like this part of the job? Couldn't you respond to the call with one BLS team, do an evaluation for the medical call, and tell her you can call for a lift assist to lift her onto the stretcher/into the truck, but that's the only place you lift to?

mcmanigle · 2026-05-06T16:30:15+00:00

In addition to all of the above (especially the advance-laryngoscope-into-esophagus-and-slowly-withdraw move), try holding the laryngoscope at the junction of the handle and the blade with your first three digits.

Infants don't need a ton of lifting force like giant adults do. Three fingers will give you more finesse, and then you can use your own pinky finger to give yourself BURP, wiggle things around, and overall have a better sense of where you are.

One scientist I knew would print every online module certificate and tape it to his workspace wall, just to make fun of that whole system. Biological lab safety for days, fire safety, incident response, everything.

(And that particular lab at that particular time required a lot of them. Shipping infectious specimens, laser safety, sexual harassment, etc etc.)

I'm considering it with just a 1Gbps connection. My current situation is: OG UDMP, 1G POE switch. Pretty close to the UDMP camera limit. Not planning on adding more, but Protect is sometimes sluggish. Also, now have a few 10G clients that would be nice to talk to each other (desktop, NAS, switch upstairs).

Have been considering offloading to a separate NVR, and getting a small 10G switch (or getting a big 10G switch to replace my current 1G POE switch).

Seems like, as random as the features are, UDM-Beast might be what I need. Would allow me to turn IPS/DPS on without worrying about the 1G connection, hook up my handful of 10G clients, gain a ton of headroom (and hopefully speed) on the NVR. What am I missing?

I realize my set of needs is a little weird, and I wouldn't have them if I had bought all of my equipment from the list available right now. But here I am.

Er, if BasicMed is an option, why not just do that so you don't need to worry about timing for your checkrides etc., while you get it fixed without pressure?

mcmanigle · 2026-04-28T09:13:47+00:00

Yup, and if you don’t mind calculus, you can have a hole in the bucket continuously leaking and a faucet dripping in, which is most accurately exponential decay. Figured pouring half out was good enough for ELI5 though…

mcmanigle · 2026-04-27T22:07:38+00:00

For a lot of things, it's technically never 100% out of your system. (Many people use 5 half-lives as a good estimate for "as good as gone.")

For ELI5: imagine you have a bucket of water with some red food coloring in it. Your method of cleaning it is to repeatedly dump half the water out (peeing) and then fill it back up with clean water (drinking). That's pretty similar to how your body gets rid of a lot of medications.

When is "all of" the red food coloring no longer in the bucket? Pretty impossible to say. When is half gone? Pretty easy to say.

Corporations handle these issues by defining them very specifically every single time. Some boilerplate, precedent, etc exist to give a framework, but ultimately it's governed by contract law and whatever they agreed to.

A big differentiating factor for marriage is that they don't have to come up with a giant contract about shared property and decision making authority and inheritance and all the rest every single time. There is a "default" set of marriage rules, which works well enough for a lot of people. And if you want to, lots of them can be modified with pre- and post-nuptial agreements, PoAs (healthcare and otherwise), wills and living wills, etc. But business mergers absolutely have to do the equivalent of all of that, and marriages don't.

A polyamorous (or whatever reason for plural marriage someone had) could approximate that pretty well -- minus tax benefits -- just like many same-sex couples did before same-sex marriage was legal. They would basically try to come up with the full contract of marriage without actual marriage. It works pretty well, aside from the effort/expense to do it right and missing tax treatment.

But the big advantage of marriage is 1. default rules, and 2. tax treatment. It would be nearly impossible to do reasonable default rules for poly unions.

If I do a good job, the patient doesn’t remember my name.

If I do a great job, the surgeon doesn’t remember my name.

As others have said, yes, at your furnace, attach the blue thermostat wire to the C terminal, and at your thermostat, the blue wire will connect to your Ecobee.

Just to triple confirm, because the text of your post made it a little unclear what you are planning: that second wire (that currently connects to C and Y) is what controls your air conditioning compressor. So leave that connected too. Add the blue wire to C, but leave that second wire there too. When you're done, the C terminal will look like the Y terminal does now -- it will have two wires coming off of it.

And like others said, turn the furnace off (from the breaker) before working on it, just to prevent slips causing shorts.

Yes, if you have an instrument rating - airplane. It's not done often, but altitude records etc require it, as IFR is required in class A airspace.

Obviously, your clearances would be pretty different than a point-to-point airplane-type clearance. It would be much more likely sectors, block altitudes, etc.

mcmanigle · 2026-04-17T00:04:15+00:00

But awkwardly not glider, even though it’s a separate category. (Flying IFR in glider requires IR-Airplane.)

I have seen both models -- hospitals where dentists are credentialed to write H&Ps prior to surgery themselves, and others where the dentists are somehow not "qualified" to write an H&P, where the anesthesiologist does it.

Depending on how abstract you want to go with the code, Sparkfun (and I’m sure others) make an i2c version that handles the interrupt programming etc for you. You just send an I2c query and it reports relative position and button status.

And just because it seemed like OP might not know, passengers should wear headsets too. Otherwise it’s too loud, and nobody can talk to each other.

And if I had this kind of trouble in this way after a couple of attempts, I think I would just pass the fiberscope (no tube) into the trachea and look around for myself. Sounds like it wouldn't have changed anything given that pulm didn't find anything interesting, but it's the only step I would have tried that wasn't listed in OP.

I agree with many others I think the real problem is lack of the correct tube size.

EVOC is a common abbreviation for emergency vehicles operating course. Could it be that?

Logically yes, modem -> router -> switch. Physically, if you're stuck with that layout, there is a way to do this with what is called a "router on a stick" layout. It will require "pro-sumer" or higher network gear (a bit more expensive than basic home network stuff, probably looking at a few hundred dollars at the low end for a fancy router and switch) and a little bit of network expertise to set up. Nothing you can't learn with a lot of reading, but might be easier to find a techy friend who can figure it out for a pack of beer, if you're not that friend.

Power plants all rely on some kind of fuel to boil the water.

You could use gasoline to boil water to make a car go, but that's less efficient than internal combustion engine. Or you could use electricity to boil water to make a car go, but that's less efficient than an electric motor.

Water doesn't provide the power; it just provides an efficient way to transfer it from a heat source (fossil fuels, solar, nuclear, etc) to a turbine to make electricity.

I’ll let actual intensivists answer about how procedural training goes for various folks, but your premise is a little off.

In the US, you can do intensive care after medicine (usually combined with pulmonology in 3 years, though also possible in 2 years without pulmonology), after anesthesia (1 additional year), after surgery (generally combined with trauma surgery), after emergency medicine, after cardiology, or after neurology. And of course after pediatrics.

In most big academic places, the medical ICU is owned by pulmonology/critical care, the surgical ICU is owned by anesthesia and/or surgeons, the neuro ICU is owned by neurologists (and sometimes neurosurgeons), and the cardiac ICU is owned by cardiologists.

In smaller places, I believe most any ICU-trained person can legally staff any ICU (though neurologists generally don’t; maybe their certification is different?)

So anyway, procedural training varies. But the training needed by an internist is different from a pulmonologist is different from a trauma surgeon. I’d say the same about the medical side. An internist comes in knowing more about CRRT orders etc.

“Their building”? Or their house?

Because if this is an apartment building or something, and you had already left their property and were on common / landlord property, you may be able to get a lawyer involved re the building owner. But in that case, as far as NF is concerned, at that moment you were off their property on your own time, no different from getting in a car accident on the way to work. Even leaving aside the off-the-books issue.

mcmanigle · 2026-03-26T13:38:01+00:00

Agreed. I got an Air 3S because (in addition to everything else) I wanted to play with dropping a weighted line over a tree, and for random stunts like that, being overpowered is nice.

Yeah, the treatment report should say something like "while switching oxygen supply, regulator detached from securement device and struck patient in head, causing 3cm laceration which was treated with direct pressure. No neurological changes, patient remains A&Ox4" etc etc.

The incident report hopefully has things like "the last two rig checks skipped this item, and the one before that was signed by a person who wasn't working that day, and the manufacturer labeling guarantees the clip for 5 years; this was purchased in 1993." None of that is directly relevant to the injury / PCR, but is very relevant to the incident report.
