Last night John’s big floor model oxygen concentrator quit! He needs oxygen 24/7 and only the large floor unit can deliver when he sleeps. It was a tense time but I finally located the service person for Hillsborough County and the rep delivered a working unit about midnight. (He drove from Zephyr Hills.)

John feels much better today. The old unit may not have delivered oxygen at the correct levels for some time. We heard a loud boom and shortly afterward an alarm sounded. It would appear to work, but his oxygen level kept dropping. It was like the unit didn’t put out oxygen. The alarm would sound after about 10 minutes of usage and his level was lower and lower.

When awake, he could use his portable unit, but when he sleeps, the portable unit doesn’t work. (He has to breathe through his nose, and when sleeping, his mouth gapes open.) The floor model is “constant flow.”

When the new unit came his oxygen levels went up and they’ve stayed there.

I shudder when I think of what would have happened if it had quit while we were sleeping. I could have lost him!
