actually an inch is close to 1/12 of the light nanosecond - again a distance not a time measurement
So then a light-nanosecond is approximately one foot. That's easier to remember, and equally useless.

Thank you guys. Now I understand what "backup rate" means.
I assume the sleep doc wrote the "backup rate" in report so that whoever setup the machine will adjust this setting, just like EPAP/IPAP settings. But I went through the provider mode menu of respironics BiPAP, I can see these options: therapy mode (bilevel/auto bilevel), ipap, epap, max ipap, min epap, max press up, bi-flex setting, rise comfort, ramp time, ramp start pres, mask alert, auto off, split night time, show ahi/leak, patient reminder.
It seems to me none of the options is related to "backup rate". Am I missing something?

Your machine model is not capable of providing a "back up" rate (assuming you have listed the correct BiLevel model at the bottom of your posts). Rather that model is a BiLevel machine that runs in spontaneous mode only.
A spontaneous-mode BiLevel machine like yours delivers
all of its EPAP-to-IPAP machine transitions based
only on the patient's own breathing transitions---from exhalation to inhalation. So a BiLevel S/T machine can be set up to provide a "backup rate" while an ordinary spontaneous-mode BiLevel machine cannot.
