How to silence alarms under specific circumstances.

I am in a pain clinic where all cases are MAC.  We use the Narkomed 2b as a back-up in case of emergency, but 99% of the time only utilize the aux. O2.  However the machine is turned on and checked daily.  How do you silence the alarm that goes constanly saying %02Low, etc.  You can silence for 120 seconds, but it is annoying to have to press the silence alarm button every 2 min during a 10 hr day!!  What is the trick to silencing that alarm for the duration, yet keeping the machine ready to go as needed?

Tubing replacement tip

I have found a simple trick to aid when replacing tubing on the NM2, 3 and 4's. I use a heat gun to turn the opaque tubing clear. It is best if you have a small diameter welding nozzle on the gun. The tubing is more flexible after treatment. This avoids the problem of having multiple lines breaking as I am attempting to change them one by one. I have found this helpful. I hope you do as well. Only heat the tubes till they are clear, any further runs the risk of melting the tube. Also care must be taken when the line runs past wires or electronics. Any residue displaced should be vented during post replacement testing.

All the best, Ron.
