The Differences Between CPAP & BiPAP

There are many different treatment options available for managing sleep apnea. We know it can be difficult to narrow down such an important decision but the most critical aspect is choosing the option that’ll provide you the most relief. The two most common options on the market these days are CPAP and BiPAP machines.

CPAP machines work by delivering a steady flow of pressurized air to the user’s airway to treat sleep apnea. While CPAP machines work with a single pressure setting that stays the same throughout the night, there are some models that come with a ramp feature. This feature starts off with a lower pressure setting and works its way up to the prescribed amount of pressure. The main function of this feature is for comfort purposes so the pressure is less forceful and immediate. Once it reaches the prescribed setting, it stays there for the night.

Many users find the single pressure setting in CPAP machines to be challenging to exhale against. If you’re a patient with a prescription for a higher pressure strength and experience difficulty exhaling against a CPAP machine, you may want to look into BiPAP machines instead. It’s also possible that your physician will prescribe you a BiPAP machine from the start if your pressure setting is high enough. You may also benefit from a BiPAP machine if you have low oxygen levels. The main difference between a CPAP and BiPAP therapy is that the BiPAP machines come with two pressure settings. You’ll have the prescribed pressure setting for inhalation and a lower setting for exhalation.

CPAP with C-Flex

While we’re discussing options, we should also take the time to discuss CPAP with C-Flex. This option is similar to BiPAP because it offers pressure relief for exhaling. C-Flex is designed to be a comfort feature for CPAP therapy and offers around 3 cm of pressure relief as opposed to BiPAP pressure relief, which begins at 4 cm and up. Another key difference is that the pressure relief you experience with C-Flex is not a fixed amount like with BiPAP. The pressure drop can vary with each breath.
