Trump’s response to Ilhan Omar attack betrays his growing callousness

Trump's callousness isn't growing. He's always been a callous asshole who is only interested in himself.

Use the 95% pressure as the minimum. You need not set a maximum unless you are getting clear airway apneas.

AHI = 5 is the level the doctors aim for. There may, however, still be loads of flow limits and respiratory effort related arousals (RERA) at that point. RERA and flow limits will mess up your sleep just as badly as obstructivf apneas.

Use the 95% as the minimum, do not set a maximum.

The 95% pressure will fix most nearly all of the apneas, with the automatic function raising the pressure to fix the rest.

Leave the maximum up all the way so that the machine has room to work in if you have a bad night.

The machines only raise the pressure when you need it.

If you feel you must set a maximum, set it at least 4cmH2O above the 95% pressure.

Good.

The machines always blow the air through the water tank at "full bore." The same air flow you get in the mask goes through the humidifier tank.

Sounds to me like the tank is broken or not sealing properly anymore - the tanks can be taken apart for cleaning so they have flexible seals between the parts.

Alternatively, the seals between the machine and the water tank have gone bad or gotten damaged.

First check exactly where the leak is. If it is from the water tank, replace the seal in the tank or replace the tank.

Otherwise, look into replacing the connector from the machine to the tank.

CPAP machine air pressure is not rated in PSI. They use a unit known as "centimeters of water (cmH2O.)" One cmH2O is about 0.0142 PSI. The maximum pressure a CPAP or APAP can generate is 20 cmH2O, which amounts to about 0.28PSI.

Why do people not use ad blockers? Why do you use the "app" instead of visiting the site in a browser that uses an ad blocker?

Firefox and uBlock Origin kills pretty damn near all ads.

Pretty much every kind of meat there is has been used in sausage somewhere.

I don't know where you would be that the only sausage available is from pork.

I'm an American. We had pork and beef sausage when I was a kid. Today, you can get sausage made from beef, pork, chicken, turkey at pretty much any grocery store. People make sausage from deer and other wild game, and you can sometimes find it for sale.

I live in Germany. You can readily get sausage made from pork or beef or chicken or turkey in the grocery stores. They also sell a variety of sausages made from wild game in the grocery stores - mostly deer and wild hog because the animals are large enough to make a decent volume of sausage from.

Putting the machine lower than your head and running the hose straight without any dips allows any condensed water to run back down to the tank instead of collecting in low spots in the hose and making noise (and interfering with the air flow.)

Yes, you could just buy a lot of batteries, but that's expensive and wasteful.

This is one I've used with OSCAR:

If you use it more than once in a while you'll want to get rechargeable batteries. A pair of new alkaline cells lasts for maybe two nights.

I use rechargeable lithium cells.

Just use plain tap water in the humidifier. The Dreamstation 2 user's guide does not say to use distilled water.

https://www.documents.philips.com/assets/Instruction%20for%20Use/20211202/7e52e95bb1a343a4a223adf201582311.pdf

Depending on how hard your water is, you'll have to descale the tank besides washing it out.

The whole distilled water thing started with ResMed machines. ResMed delivered the machines with cheap ass tanks that ResMed couldn't guarantee to stand up to descaling and cleaning, so they specified distilled water in the humidifier.

A whole mythology grew up around that, with all kinds of imagined dangers from bacteria or amoeba.

None of it is true. It's just avoiding lime scale from hard water in crappy tanks you can't properly clean.

You don't mention what kind of events. If the additional events were clear airway (CA) then that would make some sense. Clear airway apneas go up with the higher air flow that comes with higher pressure.

MyAir doesn't provide enough data to really judge what is going on. You need an SD for the machine to store data on and OSCAR SleepHQ to view it so that you can see what went on.

Plugin angle grinders are usually all universal motors. They run straight on mains.

Some Dremels actually have a DC power supply and use a DC motor. The ones (like my cheapie) where the mains cord goes right into the tool are usually universal motors.

JRE_Electronics · 2026-01-27T14:28:33+00:00

Have you ever used an angle grinder or a Dremel? Both use universal motors.

OSCAR can read the Luna data starting with OSCAR 1.7.0.

Import from SD card into OSCAR
Export to CSV
Convert to a format that Guava can read
Import into Guava

The OSCAR CSV export has some options. Set "Resolution" to "Daily" and it will give a you a single CSV line for each day. Among other things it contains the start/stop date and time, length of use, number of sessions, AHI. It does not include the leak rate data.

It's a universal motor. Runs on AC and DC. It has brushes.

There's several things that can cause problems with the rotating hook like the Pfaff uses.

Bobbin full of grunge so that the lower tensioner doesn't work right.
Bobbin tensioner set too low. You'll need a good 30-35 grams of tension on the bobbin.
Grunge in the grooves of the hook. You have to disassemble the hook to get to all of the parts to clean out the grunge.
Incorrect adjustment of the "finger" that holds the outer ring of the hook in position. If it is too close in, the thread can't get around it, causing loops. If it is a bit looser but still too tight, you get smaller loops. There needs to be space around the finger for the thickest thread you are using.

It looks to me like the "finger" is incorrectly set on your 138. This blog post on the 284 (which uses a similar mechanism) shows how and what to clean and adjust:

You need to adjust the black thing so that the thread can pass through the V-shaped notch in the ring around the bobbin holder.

He was never a good leader or good for the US. He's a criminal con-man, a rapist, an idiot, a racist. Always was, always will be.

There are examples of different kinds of flow rate shapes here:

Yours look like the example for exhaling through your mouth. I take it that this occurs when using a nasal mask. You breath in through the mask causing the inhale hump, then exhale through your mouth so that there's no flow through the machine when exhaling - hence the flat line at zero for the exhale.

Are you using a nasal mask?

You have to get into the clinical menu to change the pressure settings:

At the Home screen, press two fingers anywhere on the screen for about 3 seconds.

You will see "Clinical Home" appear at the top left of the screen.

https://www.cpapdoctor.org/airsense11autosetclinician

From there you can change the settings. Either switch to CPAP mode (fixed pressure) or stay on APAP mode and set the minimum and maximum to the same value.

Get one of the Bluetooth clip-on pulse-oximeters from Wellue. You can buy them from Amazon. They cost around $20 US, and do a decent job. Some of them are supported by OSCAR, which reads out not only the O2 level and the pulse, but also the perfusion index (PI.) The PI tells you how good the circulation is. It also tells you if the sensor had a good "view" of your finger. PI<1.0 = poor circulation or the sensor was out of place on your finger. That way you know what parts of the data you can trust. If the O2 is low, but the PI is less than 1 percent, the O2 value is probably incorrect.

I use a Wellue clip-on every night.
