The Respironics CPAP machine is a device used to regulate breathing in patients with sleep apnea. The device consists of a humidifier, a hose and a face mask to wear while sleeping. Like other CPAP machines, the system forces the wearer to breathe through her nose, which eliminates snoring. The Respironics CPAP system also contains five humidity-level settings which the patient can adjust to her specific comfort level.
Fill the CPAP water tank with water until it reaches the fill line marked on the tank.
Plug the Respironics CPAP machine into an electrical outlet and turn it on.
Look at the digital display screen located on the top of the CPAP machine. This is where the relative humidity percentages are displayed.
Turn the dial located below the digital display screen until the desired relative humidity level is achieved. There are five levels to choose from. Below are the relative humidity percentages for each level as displayed on the Respironics website. Level 1 - 80 to 90 percent relative humidity Level 2 - 70 to 80 percent relative humidity Level 3 - 60 to 70 percent relative humidity Level 4 - 50 to 60 percent relative humidity Level 5 - 40 to 50 percent relative humidity
Put the mask on to test the comfort level of the selected humidity setting. The air should be comfortable to breath, but not humid. If the air is too moist, lower the relative humidity level on the CPAP machine until you achieve the proper comfort level.
