I forgot to mention that it rained most of the day yesterday... it started just as I got to work, and it's continued off and on ever since. Oddly, I have carried my umbrella to and from the truck both days and not had to open it. Just lucky. Yeah, I know what happens if I forget to take it in with me in the morning. Another lousy night and another busy day and I'm getting tired of both of those things. Last night I woke at 03:00 and I was awake and up off and on the rest of the night, dammit. Clogged-up nose, which makes the CPAP not work. I need a CPAP working to be able to sleep. And then I go to work and there's not a minute to sit down, which is probably good because it would have been really hard to get back up. There's something odd going on at work with the machine failing at certain times on certain exams, it's happened five times now, but it's never happened when I was sitting at the console setting up the same exam... it's worked flawlessly every time for me. I don't know if it's just a fluke, or if there is some little thing that I'm doing right that everybody else is missing. To kinda explain things, the exam that we're doing is a CT angiogram, looking for pulmonary emboli... blood clots in the lungs, specifically the pulmonary artery. The way we do that is to inject contrast material through a venous access point, usually an antecubital vein, and it goes into the superior vena cava, into the right atrium, into the right ventricle and then into the pulmonary artery, where it's distributed to the lung to be oxygenated. As you can imagine, timing is critical. We usta just guess, and we were right about 80% of the time. Now we're a lot fancier, we actually measure the density in a spot in the PA and trigger the exposure off of that. There is no way to miss... if everything works right. Setting it up is a pretty straightforward but lengthy procedure, and I can't believe that my co-workers aren't doing it right...but I can't think of any reason why I can make it work and they can't. I watched most of the setup of the last one that failed and I didn't see anything amiss. On the other hand, we're doing it all with computers, so who knows? Once I got home tonight, I knew that I wouldn't want to get out again, but I had to go to Walgreens and get some pharmaceutical necessities. And I was planning on going to sleep early, but that's not happening either. Karen is already in bed, it's rare that she goes to bed before me, especially lately. She was complaining of not getting enough sleep last night either... she went to bed in the spare bedroom with Lacee, but she woke up and came to bed about 02:00. Just checked the radar, there's a fierce-looking line of storms about 70 miles west of here, if they hold together they'll be here about 03:00 to wake me up, I'll bet. I might just sleep through them.
