Two hats, one style

After wearing a wool hat for years, I bought a Stetson open road. It is styled as a snap brim fedora.

Rather than taking my Stetson with me on a trip next week, I cleaned up my old wool hat and gave it a styling. The Stetson cost too much to risk losing or damaging on a plane.

The old wool hat isn't as snazzy as the Stetson, but it'll do to keep my pointy head dry while exploring Ireland with my wife.

The wool hat had sweat stains and so many cat hairs I'd swear the kitty had been sleeping in it. It took a good sized piece of duct-tape to get all the cat hair off. A gentle scrubbing with a damp cloth and a mild soap got rid of the sweat stains.

The hat says "crushable" on the inside, and crushed it has been. I mixed up a really thin solution of shellac and ethanol to stiffen it. I shaped kind of like I wanted it, then let the sprayed on shellac dry

A little steam from the vent on a pot let me refine its shape to be similar to the Stetson. The wool doesn't hold its shape as well as the thinner felt on the open road, but I think it worked out well.

The brim on the wool hat doesn't "snap" like the open road. Wool just hasn't got it in it to do so.

The band on the wool hat is custom made. The LEDs light if a phone gets closer than a couple of inches from the concho. No batteries, purely passive. The Stetson will get a similar band, but I haven't gotten around to designing a new, smaller circuit board for it.

I had a polysomnograph checkup on Tuesday night, with the evaluation in the doctor's office the next day.

The doctor was thrilled with my results, though somewhat concerned with the pressure settings - it seems that 18cmH2O minimum with pressure support 5 is rather at the high end and that apparently most folks don't deal with the pressure well. The sleep lab techs even asked me if I had changed the settings - they were ready to call and chew out the equipment provider for giving me a machine with such screwy settings.

All was good, though. The doctor was impressed by my OSCAR charts and the methodical way I had documented the changes and the reasoning and the things I had done besides just diddling with the pressure (breathing exercises on a didgeridoo, compression stockings to reduce the effects of edema on my apnea.) He was also impressed that I make my own mask straps - it seems it is unusual for folks to do such things.

The polysomnograph charts agreed with my OSCAR results:

I didn't get a copy of the lab report, but I saw, and it agreed 100% with OSCAR.

Lowest RDI I've ever had. Highest steady breathing rate I've ever had. Pulse the most stable I've ever had.

All to the good, right?

Confusing as hell is more like it.

This week has been pure chaos. My mother-in-law is in the hospital, due to come home on Friday. We visit her on alternate days (my wife's brother does the other days.) When mother-in-law gets home, she's going to have to live in just the downstairs floor of their house, so my wife and I (and some neighbors) spent Tuesday tearing down furniture and rearranging rooms so that her bedroom is now where the dining room was. I've had a cold this week, and it is a bugger - a dry hacking cough that I don't wish on anyone. I wore a mask all Tuesday while working so as not to spread my germs too far, and had to take codeine to relieve some of the coughing - each cough felt like someone was trying to split my head with an axe. We busted ass all day long, with a break for me to drive over and pick up the polysomnograph equipment. It was midnight before I got to bed, and I had to take some Vick's Medinight to stop coughing long enough to fall asleep. Around 04:30, the cat woke me up. No reason, just "meow" until I got up to look, and found her laying her bed, blinking and looking like "why'd you have to turn the lights on?" I found that the tubes for the polysomnograph had gotten wrapped around the air hose, and were bent over so that it looked like no air could get through them. I straightened them out, but thought that had ruined the results. Nope. The full night on the polysomnograph had good data.

I am confused:

  1. How did the polysomnograph get good data despite the tubes being kinked shut?
  2. How in the name of little green boogers did I get score that good while loaded with codeine and Medinight?
  3. Did the exertion while wearing the mask strengthen my breathing?
  4. Did sweating in the night due to a slight fever have anything to do with it?
  5. Does wearing a doctor's filter mask improve my breathing or do something positive for my lungs? (I cough less while wearing the mask. The air I breathe with the mask on is warm and moist, possibly reducing irritation in my lungs.)
  6. Does breathing just through my mouth have some effect on things? (My nose has been stopped up off and on for the last couple of days. I had another good night last night, but woke up completely unable to breath through my stopped up nose.)

I'll be doing some experiments in the coming weeks to see what's going on, starting with the mask. That's the safest part to play with. I don't like to mess with codeine. It stops the coughing (mostly) but it also stops up the other end. I don't like balancing "not coughing" against "taking ex-lax." Sweating at night is easier to simulate - just toss on an extra blanket. I've got nose plugs for swimming ordered to see if forced mouth breathing makes any difference.

The doctor and his boss are both positively impressed by OSCAR. While I was at the front desk, making an appointment for next year's checkup, he came out and asked if he could borrow the printed OSCAR charts for a moment to show his boss. She had seen them on my last visit, and wanted another look. I gave him a complete set (to keep) going back to 1 January, 2025 (that's when I got my second Löwenstein Prisma and started getting really serious about this CPAP stuff.)
