Standby and Monitoring Screens
You first of all should locate standby and monitoring screens. These two screens can lead you to access many settings of the machine. So better locate the screens by plugging Bipap in. Watch then for appearing of standby screen, which should display the numbers '888.8'. then if you press the On and Off button on left of the display panel, you will see the monitoring screen popped up. It should display the number '888.8' as well.
Rise time is the amount of time that the Bipap machine takes to change from exhaling pressure to inhaling pressure. You can change this time. From standby or monitoring screen, and press the 'user' button from the control panel on the right side until it displays the 'Rise Time'. You can then use 'Heat' button to increase the time of the pressure or use 'Ramp' button to decrease the pressure. Do make excessive changes in the panel, as this can affect the pressure in the mask and might cause trouble in breathing for you.
You should modify ramp pressure. The option provides the lower air pressure while you are asleep. The adjustment gradually increases the pressure, while you continue to sleep. You can adjust the pressure from the standby or monitoring screens by following the same procedure as you have done while adjusting the rise time. Choose the heat button to increase the air pressure and ramp button to lower the pressure. The adjustment in the pressure can help you sleep more comfortably as this will increase the breathing process.
