Positive airway pressure (PAP) is one of the most common treatments for sleep apnea, a breathing disorder that affects approximately 10% to 30% Trusted Source UpToDateMore than 2 million healthcare providers around the world choose UpToDate to help make appropriate care decisions and drive better health outcomes.

The most common PAP treatment is continuous positive airway pressure (CPAP), but bilevel positive airway pressure (BiPAP or BPAP) may be a better option for some people.

While both forms of PAP therapy work in similar ways, their differences mean that each has distinctive benefits and drawbacks to consider. Because of this, the decision to switch PAP treatments should always be made under the advice of your health care team.

In general, CPAP machines have an adjustable pressure setting that delivers between 4 to 20 cm H2O Trusted Source UpToDateMore than 2 million healthcare providers around the world choose UpToDate to help make appropriate care decisions and drive better health outcomes.

The average setting is between 8 to 10 cm H2O Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source . While CPAP machines have only one setting, some models now have a pressure relief option that allows for gentler air pressure on the exhale.

There are portable CPAP machines designed for travel, while BiPAP machines are designed for at-home use. Because BiPAP machines require additional sensors and settings, they are usually more expensive than an otherwise similar CPAP machine.

Different types of PAP therapy work better for different conditions, though there is some overlap Trusted Source National Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source . CPAP therapy is generally recommended for obstructive sleep apnea (OSA), and sleep specialists are unlikely to place someone with OSA on BiPAP unless they cannot tolerate CPAP treatment. While some insurance providers cover both CPAP and BiPAP for OSA, those that do usually require proof that CPAP treatment is inadequate or not tolerated before reimbursing for a BiPAP machine. BiPAP therapy is primarily used to treat central sleep apnea (CSA), as well as heart, lung, and neurological disorders that require structured airway support during sleep.

Both CPAP and BiPAP machines are available with a range of accessories, both integrated and after-market. The most common are data collection features and climate control features like humidifiers and heated tubing.

CPAP machines continuously pump air at one pressure setting rather than varying in pressure between the inhale and exhale, which can cause some people to feel as though they cannot exhale properly or that they are choking. Most users adjust to CPAP relatively quickly, while others find BiPAP easier to tolerate.

Unlike BiPAP machines, CPAP machines are available in a range of sizes. The most common type is intended to be used at home and is slightly smaller than a shoebox, while travel versions may be small enough to fit in the palm of your hand. Travel models sometimes have backup batteries for use while camping, and FAA-approved models are available for use on planes.

Bilevel positive airway pressure machines have distinct air pressure settings for inhalation (IPAP) and exhalation (EPAP). The EPAP setting is usually significantly lighter than the IPAP setting, allowing users to breathe more naturally and not feel as though they are fighting against the machine when they exhale. Most BiPAP machines have a range of approximately 4 to 30 cm H2O.

Although CPAP and BiPAP machines may seem similar, their differences can have a significant impact on your treatment. Because of this, the decision to switch from one to another should always be made with your health care team.

CPAP users usually have an adjustment period before they feel comfortable using their machines. Discomfort can be managed by adjusting settings, experimenting with climate control accessories or different mask types, or using a machine that slightly reduces air pressure on the exhale. BiPAP treatment is available for patients who do not tolerate CPAP therapy, but this switch must be decided on and supervised by a sleep specialist.

In general, your CPAP pressure setting should be just high enough to keep your airway open. When your pressure is too low, you may suffer from the symptoms of sleep apnea. If your pressure is too high, you may struggle to keep up with your therapy, have nasal congestion, and experience choppy or fragmented sleep.

Your CPAP machine measures several things, including one key metric that sleep professionals use to determine the severity of your Obstructive Sleep Apnea (OSA). This is called the apnea-hypopnea index (AHI), and it indicates how many times you stop breathing over the course of an hour of sleep.

CPAP machines can be adjusted between 4 and 20 cmH2O. APAP machines also operate in that range, but since they are automatic, they are not set to a fixed number as a CPAP machine would be. Rather, they are capable of adjusting themselves within that range. BiPAP machines are slightly different as they can be adjusted to lower than 4 and higher than 20.

Automatic positive airway pressure (APAP) machines automatically adjust themselves to your changing breathing patterns throughout the night. If you are like many people with sleep apnea, you tend to have more frequent bouts of paused breathing at some times of the night over other times. APAP automatically adjusts your air pressure settings to fit your changing breathing patterns.

Your APAP machine is capable of adjusting itself within that 4 to 20 cmH2O range, so if your sleep apnea symptoms resurface while using an APAP machine odds are the culprit here is either a leaky mask, a change in your health, or something is wrong with the machine itself. Regardless of the potential source of the problem, if you begin experiencing your sleep apnea symptoms again while using an APAP machine, you should consult your specialist to narrow down possible causes.

A Bilevel Positive Airway Pressure (BiPAP) machine delivers two different air pressures to keep your airway open as you sleep. The machine senses when you inhale and exhale and produces different pressures accordingly. The BiPAP machine produces a high enough pressure to hold your airway open when you inhale and then produces a lower pressure when you exhale, making breathing easier.

Additionally, some people find it difficult to exhale over the constant pressure of the CPAP machine, which in turn, also complicates inhalation, making a BiPAP machine the best option for them. BiPAP machines are also adjustable to as low as 3 and above 20 cmH2O, unlike CPAP and APAP machines that are normally calibrated between 4 and 20 cmH2O.

In most cases, if you use a BiPAP machine, there are also other special circumstances associated with why you are using BiPAP instead of CPAP or APAP. Your first line of defense to fixing the issue if you are experiencing sleep apnea symptoms again will be to examine your mask for any leaks or begin utilizing a humidifier.

While we hope to relieve some pressure (no pun intended) for you in understanding your PAP pressure settings, remember to contact your sleep specialist first if you have any questions about your pressure settings.

If your machine is linked via a modem to the supplier like mine is they know the settings at all times I monitored. That is a same way to know you are doing ok pressure wise an equipment. I have Respirionics Equipment.

When you buy a new CPAP machine, you will need to have a prescription on file, and that prescription will have your pressure setting on it. We will set the pressure before sending it to you. If you need help tracking down the old prescription you can reach out to us at our number for international customers: +1 713-351-3414. Perhaps we can help you work out a solution to your problem that will get you back into CPAP therapy.

I have trouble with mask leakage. If I adjustthe headstraps to stop air leakage I have to cinch it up until it hurts. I get new masks every 3 months. I mask usually last a month. This is very uncomfortable and makes me not to use my BIPAP but I have frequent long period of not breathing without my BIPAP.
Thank you for helping

You might want to consider using a mask liner, as an inexpensive way to reduce the amount of leakage from your mask. Mask liners are great at improving the seal and making the mask more comfortable too.

Some machines have optional exhalation relief. The machine automatically senses when the user is exhaling and reduces the pressure. For example DeVilbiss calls this feature smartflex. Do you know what the difference is between Smartflex and a Bi-pap machine?

My doctor gave me a pressure of 4. I had to buy the CPAP out of my own pocket and pay cash, because it was a percentage point above where Medicare would pay for it. My doctor has his own sleep study center set up in his own office. My doctor also said he would do a stem cell treatment for $1000 below another well experienced physician. My doctor had only done 10. I say this because it was obvious that my doctor was seriously worried about not making it financially. My doctor quit earlier this year by way of an email. He went to work for the VA. Do you think I need a CPAP machine?
