If you have obstructive sleep apnea, your nights are broken into periods of snoring, apnea (no breathing), gasping and some normal breathing. A bilevel positive airway pressure (BiPAP) machine, such as the BiPAP Pro 2 model from the company Philips Respironics, is made up of a unit that compresses air, a nasal or facial mask and tubing. It produces a stream of air at a higher pressure when you inhale and a lower pressure when you exhale to keep your airways open and promote a good night’s sleep.
Find the standby and monitoring screens. Plug the Respironics BiPAP Pro 2 machine in and watch the display on the top of it until you see the standby screen, which has words such as “patient” and “hours” displayed. You can hold down the “pressure on/off” button on the control panel until you see the monitoring screen on the display. It will have a number and “cm H20” displayed.
Locate the session-counting view screen. From the standby or monitoring screen, hold down the “ramp” button until you see the word “nights” with a number to the left of it.
Adjust the flex setting. This option tells the Respironics BiPAP machine to give you some pressure relief when you’re exhaling. Go to the session-counting view screen, and press the right “user” button on the control panel until the display says “flex.” Use the “heat” button to increase the number on the screen and the “ramp” button to decrease it. No. 1 provides the least relief, while 3 provides the most.
Change the rise time. This option allows you to control how long it takes your Respironics BiPAP machine to change from your exhalation pressure to your inhalation pressure. Go to the session-counting view screen and press the right “user” button on the control panel until the display says “rise time.” Use the “heat” button to increase the number and the “ramp” button to decrease it. You can choose a rise time from zero (fastest) to 3 (slowest).
Adjust the ramp starting pressure. This setting provides a lower air pressure while you’re falling asleep, with a gradual increase (ramp) in pressure over a period of time. From the session-counting view screen, press the right “user” button until the display says “ramp start.” Press the “heat” button to raise the number and the “ramp” button to lower it. Choose a ramp starting pressure between 4 and your pre-programmed exhalation pressure.
