BiPAP ST Rx: Back up rate=0
#1
BiPAP ST Rx: Back up rate=0
Hi,

I just got a new prescription to change from CPAP to BiPAP ST. The prescription has my back up rate at 0. That doesn't seem to make sense to me. Doesn't that mean the breath per minute is zero, so it would never alert me if I stop breathing?

Thanks!

You have posted no information that would help us make a judgement. I don't know what your results were for CPAP, or what any sleep studies showed. What's the problem? Do you have CA? Obstructive or restrictive pulmonary disease? Why did you fail CPAP?

RE: BiPAP ST Rx: Back up rate=0
Hi,

My sleep study showed more than 50% CAs and with CPAP I couldn't get my AHI to lower than about 11. A sleep therapist said I needed to be on BiPAP ST with CAs. I just got my Rx and I am confused as to why the back up rate is 0. I haven't gotten my new machine yet, so I haven't tried therapy on the BiPAP yet, but i was wondering if it made sense to have a back up rate at 0.

Thanks,
Jgoole

jgoole, the ST is not an ideal machine, I would think for complex apnea, ASV would be the correct application; either the Resmed Aircurve 10 ASV, or Philips Respironics SV Advanced. The ST may work, but it's not the ideal machine.

If you have centrals, the machine must be set to have a backup rate and enough IPAP pressure to overcome CA. Unfortuneately, you will also get that IPAP when you're spontaneously breathing because that machine is designed for restrictive, or obstructive pulmonary disease or obesity related hypoventilation. You can do a google search and compare ST and ASV and you will see what I mean.

An appropriate backup rate is your normal respiratory rate (BPM) minus 2. For most people, that will be a backup of 11 to 14 BPM. Can you relate your other settings?
