Practically speaking, that is probably close enough,
considering the negative effects of complete discharge.
As you mentioned, discharging the battery 70% in 5 hours
leads one to believe that we are looking at 14% discharge
per hour, or a total run time of about 7.1 hours before
the battery is totally flat.
(70% discharge / 5 hours = 14% hourly discharge rate)
and 1 / 14% = 7.14 hours total run time)
Your CPAP unit appears to be drawing about 3.36 A because:
24 AH / 7.14 hours = 3.36 A or about 41 W
Looked at another way, 3.36 A * 7.14 H = 24 AH
That is not *quite* as high as 5 A.
