Why do I need to use my CPAP/PAP therapy equipment and for how long?

PAP therapy was prescribed by your physician and is to be used every night and during naps. CPAP equipment is portable, lightweight and may be taken on vacations and business trips. If you find it difficult to wear your CPAP at first, try to wear it as long as you can tolerate it; 4 hours is considered therapeutic. Try to work up to the entire night as it may take time to adjust using your CPAP.
