If you have obstructive sleep apnoea, you spend your nights snoring, pausing your breathing during periods called apnoea, gasping, and then snoring once again. Continuous positive airway pressure (CPAP) machines create a steady stream of compressed air at a predetermined pressure to keep your airways open and stop the cycle of sleep apnoea. ResMed sells CPAP machines with a small programmable unit to compress the air, a face or nasal mask that attaches firmly, and tubing to connect the compressor and the mask. The CPAP machine will be programmed when you obtain it, but you can make some changes at home. Each model has its own instructional manual, and this article focuses on the C-Series Tango model.

Things you need
- Your ResMed CPAP machine
Locate the Tango interface. This control panel, which allows you to change settings, is located on the top of the programmable unit and has the word "Tango" imprinted above a display window.
Locate options for ramp time. The ramp feature allows you to set your machine to deliver air at a lower pressure while you're falling asleep. The pressure will gradually rise to the level prescribed by your doctor over a preset amount of time (the ramp time). Your options are 0, 10, 20 and 45 minutes. Press the ramp button (a triangle pointing left and located in the lower left section of the Tango interface) repeatedly until it shows a number.
Adjust the ramp. To adjust the air pressure for the ramp, press the ramp button until the desired number of minutes is visible in the display window. Press the power button (the circular button on the bottom of the Tango interface) to save that ramp setting.
Adjust the humidity. If you have significant nasal dryness in the morning, for example, you can increase the humidification of the air delivered through your CPAP. Locate the humidity button (a horizontal line with three wavy vertical lines above it) on the right side of your Tango interface. You can increase or lower the amount of humidity of the air by pressing the up and down arrow buttons to the right of the humidity button until you see the desired setting. Press the power button to save your changes.
Adjust for your altitude. If you're travelling to a location at a significantly different altitude above sea level, your machine will work best if you adjust it accordingly. Locate the altitude button (a mountain range with jagged peaks) on the upper left side of the Tango interface. Hold it down for three seconds until you see the desired altitude in the display window on the Tango interface. Use the up and down arrows to select the best option from one of four altitude readings. Press the power button to save that setting.
