I was given a Resperonics Cpap with 9000 hours on it. Can I expect
this thing to go a while longer or is it at the projected end of the unit?
It still seems to function fine. I used it the last couple nights without
issue. I was going to use it for a backup/travel machine. How many hours do these things last on average?
The usual insurance approved replacement schedule for the machine itself is typically about 5 years. Although many people have no trouble using a CPAP far longer than the 5 year replacement cycle.
If we "guesstimate" that an average person sleeps roughly 7.5 hours per night, then the expected 5-year life span for a CPAP would be:
7.5 * 365 * 5 = 13687.5 hours.
As a back up unit this machine ought to be fine. You might want to have it checked out by a DME to make sure that it is blowing at an accurate pressure level however.

How long will my CPAP last?
The average life expectancy of a CPAP or BIPAP machine is approximately 20,000 hours, or roughly 7-8 years full time use. That said, many times, if properly cared for, these devices will last much longer. Many properly maintained machines will last upwards of 50,000 hours.
