Moving beyond the abilities of C-FLEX on CPAP machines, AFLEX offers a more sophisticated analysis of breathing cycles and adjusts the pressure accordingly. The machine adapts to meet the changing air pressure needs of CPAP wearers on a person-by-person basis rather than offering a one-size-fits-all approach to adjusting the airflow. This means patients do not need to work as hard to breathe against the machine while maintaining the appropriate supply or air pressure coming in while inhaling. C-FLEX accomplishes this by reducing air pressure sent into the airways prior to exhalation and restoring them to the prescribed settings just prior to inhalation. The goal of C-FLEX is the same as the goal of EPR – to make wearing CPAP masks more comfortable for patients with obstructive sleep apnea (OSA). What is CFLEX?Ĭ-FLEX is similar to EPR and is used by different CPAP machine makers. The feature essentially makes it more comfortable for CPAP users to use their devices throughout the night, improving compliance which offers better outcomes for CPAP patients. If you choose an EPR or three, for instance, and your normal pressure setting is 10, the machine will automatically reduce the pressure to seven when you’re exhaling then return it to 10 when you inhale. How does EPR work? The three settings allow CPAP wearers to reduce the pressure by one, two, or three pressure points when exhaling. What is EPR?ĮPR stands for “expiratory pressure relief.” It is a feature on some CPAP machines that allow users to adjust between three different comfort settings to alleviate feelings of breathlessness some CPAP wearers complain about. Work with your sleep technician to identify the best choice for you. There are devices that provide different ramp settings to meet the needs of different CPAP wearers. The CPAP ramp is most commonly used to increase the air pressure incrementally, every five minutes, over a 45 minute period of time. Since the actual purpose of the CPAP machine is to deliver a stream of air while you sleep, the ramp feature, as its name implies, serves as a ramp that starts out delivering a lower amount of pressure allowing wearers the opportunity to fall asleep before the higher pressure settings engage. Breathing against this powerful stream of air, especially for people who have higher than average prescribed pressure settings, can be discouraging and may even affect compliance.Įnter the CPAP ramp feature. One of the challenges for many CPAP wearers is exhaling against the continuous pressure stream. What Does My CPAP Ramp Setting Mean?ĬPAP machines deliver a fixed amount of pressure into your airways at night. Others may even need to consider varied pressures throughout the night, particularly those who shift sleeping positions and at different sleep stages. Though it is true, to some degree, that people with severe OSA often do require higher settings to maintain unobstructed airways while sleeping, other contributing factors play roles in determining this, including: In fact, there are numerous factors that determine which setting is the most appropriate for individual CPAP users. While many people believe that the pressure settings are determined by the severity of the sleep apnea, that isn’t necessarily the case. Most CPAP users require more than the minimal CPAP pressure settings and less than the maximum settings. The pressure reading is typically abbreviated as “cm of H2O” or “cm of CWP.” The lowest setting on most CPAP machines is four or five CWP with maximum settings as high as 25 or 30 CWP (depending on the type of machine you have. The CPAP pressure setting indicates the amount of pressure behind the air being sent through your mask at night. These are some of the CPAP settings you’ll want to become familiar with as you explore your CPAP machine and learn more about how it works for you. You’ll receive optimal benefits from your sleep apnea therapy when your CPAP machine settings are where you need them to be to keep your airways clear and unobstructed throughout the night. CPAP machines can make a world of difference in the quality of sleep you receive each night if you’re a sleep apnea patient.
