The improvised power supply failed. The CPAP has some kind of sensor in it that detects pressure and I think the power from the supply was erratic enough to fool the sensor into "thinking" I wasn't breathing.
So every breath resulted in the CPAP turning on and then off. Needless to say I didn't use it after that arose. So I've had my first night without the machine for a while.
It's deeply disturbing. I'm aware I can't breathe and I keep waking up.
