What is ramp on a CPAP machine?

Ramp on a CPAP machine is a feature that gradually increases the air pressure over a set period of time when starting therapy. This allows users to become accustomed to the increased air pressure and helps to reduce the discomfort associated with starting CPAP therapy. The ramp time can be adjusted to suit individual preferences, typically ranging from 5 to 60 minutes. During the ramp period, the air pressure will start at a low setting and gradually increase until it reaches the prescribed pressure level. This helps to make the transition to full therapy pressure more comfortable and can reduce the likelihood of users waking up during the night due to discomfort.
