"Dafydd ab Hugh, Brad Linaweawer DOOM: Hell on Earth (english)" - читать интересную книгу автораThe pressure dropped so gradually, we didn't even
notice. After a while I found myself panting for air after climbing a ladder, and Arlene had to rest after every heavy part she handed me. Then a couple of days later, I realized my mind was ' wandering in the middle of a task. I focused, then wandered again. Arlene was able to maintain her concentration; maybe being smaller, she didn't need as high a partial pressure of oxygen. But both of us were getting mighty cold. When I saw Arlene shivering while working, I made her throw on a couple of sweaters and did the same. We wore gloves, except that I kept removing mine because it interfered with the work. Then my hands would turn to ice, and I'd put them back on to warm up before taking another stab at attaching the fine filaments that ran microvolts to the plasma globules. Suddenly, the air-pressure sensor started screaming its fool head off. Arlene and I exchanged a worried glance, but we didn't need to be told twice. It was time to start hitting the raw stuff, O2 neat. We took hits off the same oxygen bottle, trying to limit ourselves to a few breaths every hour or so, or when we started to get dizzy or goofy. Uncle Sugar packed a lot of air into a single bottle; but even so, even at the slow pace we used it, we'd run out of breathing oxygen in just a few more days. We had more bottles, but we needed them for fuel mixing. And of course we'd need to breathe more frequently as the pressure droppedЧparadoxically, it was drop- ping slower now, since there was less pressure in the dome to push the air out. We stretched the bottles as long as we could, but they ran out while there was still plenty of work left. I'd done mountain climbing in my native Colorado before joining the Corps; as the air grew thinner, I tried to help Arlene deal with it. "Breathe shallowly," I said. "Rest, and don't talk except for the job." The physical exertion wasn't any less, though. We'd have to stop frequently, gasping and panting. We tired easily and needed more sleep, but stayed on the four- hour rotations, creating a cycle of exhaustion we couldn't break. But sleeping longer would just make the job take longer, and the pressure would drop lower in the meantime. Low pressure is insidious. There are obvious ef- fects: exhaustion, trouble breathing, and cold. But there are other symptoms people don't often think |
