Question:
Can you use a CPAP machine with a Shabbos clock or it is still an issue b/c the machine is still recording the changes in your breathing patterns and breathing pressure and is raising or lowering the air pressure in accordance to your breathing patterns and breathing pressure minute by minute. So, is it an issue that you are causing the computer to be recording and changing circuits while sleeping or not?
Answer:
