Hyperbaric Monitors

What kind of monitors are you using in your hyperbaric chamber?

I'm a critical care nurse and work part time and on-call in a hospital based multiplace chamber hyperbaric program.

I frequently dive with ICU patients who are obviously monitored.

Lately my monitor (a ProPaq 106) has been acting up and giving me errors, etc. In monitor years it's about 115 years old. I've talked with BioMed /clinical engineering and been told not to break it further as parts are no longer available.

I'm looking for a new monitor that is usable in the chamber. We monitor from the inside and don't penetrate the hull. My vent goes in as well. Anything we use has to have a solid battery life and be less than or equal to 25 volts. Shouldn't have NBP as those are run by electric brush motors.

We're a large multiplace chamber and can go to 6ATA or 165 FSW, so it needs to be able to handle some pressure.

The ICU's here use Spacelabs and I've checked with the manufacturer, none of their gear is hyperbaric compatible.

So please let me know what you're doing in your center. Any suggestions or thoughts would be greatly appreciated.
