SleepyHead - How to import and overwrite a day?

[MyronH]

I have a trial BIPAP machine I was using for most days. But for one day, I temporarily switched to APAP and imported that partial day. But then switched to my BIPAP.

Currently March 25th shows my AirSense data. I want to overwrite this with my Aircurve data. How do I do that?

To purge a day's data in SleepyHead:

1. Switch to the Daily screen.
   
2. Select the date of the day you wish to purge.
   
3. Go to Data -> Advanced -> Purge Current Selected Day.

When using two different machines there is no need to purge data. Both machines are tracked in separate data-sets and can coexist and be displayed separately.
