My partner sleeps with it every night. So 7-9 hours.

Hi Peggy. Your DOC will prescribe the correct settings and duration for using the TRILOGY machine DAILY. The insurance company probably dictates a minimum 5 hours per day for payment coverage. Your Medical Equipment company will send the usage data to your Doc on a regular basis.

But you are free to use it in other places and at other times as you see fit. The rechargeable battery will permit use in other areas of the home or while away on travel.
be Well
