Had sleep study last night: calling all auto cpap users!

My wife was so bad during her test they woke her up and she had the machine the next mornning. We have Kaiser. Still she often does not use iit. The hose she has allows her to put it on the floor though I made her a shelf. She has the humidifier model. We were surprised it would not run through our four hundred watt power inverter. That is still a mystery. Best of luck to you
