CPAP is continuous positive airway pressure. It may be prescribed by a doctor to treat a disorder such as sleep apnea. Usually a person has to undergo a sleep study before CPAP will be ordered. CPAP helps by keeping the airways open and improves breathing. Machines for home use include the Respironics CPAP machine. Its important to understand how to set or adjust the pressure on your unit.

Get familiar with the machine. Locate the on and off button and the two user buttons, which allow you to move into different menus. Find the ramp button, which you use to select the setting you want when in a particular menu. There is also a display screen on the front of the unit where you can view your settings.

Plug the power cord of the Respironics CPAP unit into the wall outlet. Pull the other end of the power cord out of the back of the machine.

Hold down the two user bottons on the front of the machine for a few seconds while simultaneously plugging the power cord into the back of the machine. This will allow you to enter the therapy setup menu. Press the user button on the right to access the “Choose the Mode” screen on the display menu.

Choose the mode. Respironics machines have two modes, CPAP and C-Flex. Your doctor will prescribe one of the modes for you. Press the ramp button to select either CPAP or C-Flex as your mode.

Set the pressure. Press the user button on the right to get to the “Set the Pressure” display screen. Use the ramp button to set the pressure your doctor ordered. The pressure can be set from 4 to 20.

Keep in mind that as you hit the ramp button numbers will appear on the display screen. Each time you hit the button you will increase the pressure by one. Press the ramp button until the correct pressure appears.

Warnings

Don’t change you CPAP pressure without talking with your doctor. A specific pressure was predetermined through your sleep study. Be aware Respironics makes a few different models of CPAP machines. Each machine’s display screen may vary slightly.

If you have been prescribed continuous positive airway pressure (CPAP) therapy to treat obstructive sleep apnea, you may wonder: Does the severity of sleep apnea measured by the apnea-hypopnea index (AHI) correlate with the needed CPAP pressure for effective treatment?

Learn if (and how) the prescribed CPAP setting is related to the underlying degree of sleep apnea and what other factors might be involved to determine your optimal treatment, including anatomy, sleep position, and sleep stages.

Sleep Apnea Severity

It is only natural to assume that there would be a relationship between the prescribed CPAP pressure setting and the degree of obstructive sleep apnea that is being treated. If you need a medication for blood pressure, a higher dose naturally would have a greater effect, right? Well, unfortunately, the relationship is not quite so direct when treating sleep apnea.

Obstructive sleep apnea (OSA) is diagnosed with an overnight sleep study or home sleep apnea test that assesses the number of times per hour of sleep that the upper airway collapses, resulting in a drop in blood oxygen levels or awakenings from sleep.

If the airway completely collapses this is called apnea and if it partially collapses this is called hypopnea. The total number of these events per hour of sleep is the apnea-hypopnea index (AHI).

AHI and Severity

The AHI allows a general classification of the severity of sleep apnea:  

  • If there are fewer than 5 events per hour, this is deemed to be normal.
  • If 5 to 15 events per hour are recorded, this is mild OSA.
  • If more than 15 but fewer than 30 events are observed, this is considered to be moderate OSA.
  • If more than 30 events are recorded per hour of sleep, this is characterized as severe OSA.

You might think that severe OSA requires a higher CPAP pressure setting to treat it. In actuality, this is not always the case as there are multiple factors involved in determining the required setting. Typically, the treatment starts at a low setting and is gradually increased to resolve all apnea and hypopnea events as well as snoring.

The lowest setting on CPAP machines maybe 4 to 5 centimeters of water pressure (abbreviated as cm of H2O or CWP). The vast majority of people require more pressure than this lowest setting. The maximum setting varies with the type of machine, but it could be as high as 25 or 30 CWP.

Determining Required CPAP Pressure

If the CPAP setting is determined as part of an overnight titration study in a sleep lab, a polysomnography technologist will observe the breathing patterns and adjust the setting upwards while you sleep. This is done remotely from another room so that disturbances do not occur.

The goal is to eliminate the sleep apnea and snoring and observe deep sleep, including rapid eye movement (REM) sleep. This setting should also be optimized while sleeping supine (on your back) when sleep apnea often worsens.

Some people are sent home with a self-adjusting CPAP machine, sometimes called AutoCPAP or APAP. In this scenario, the prescribing physician allows a range of pressures.

The machine will start low and adjust upwards as needed in response to measured airway resistance (suggesting persistent collapses of the soft tissues like the base of the tongue or soft palate into the throat).

The CPAP delivers intermittent pulses of extra air pressure to evaluate for resistance and, by extension, whether the upper airway is collapsing. If the airway is open at the current CPAP setting delivered, it is maintained.

The required CPAP pressure does not directly correlate with the severity of sleep apnea. Some people with mild OSA need high pressures and some people with severe OSA need relatively modest pressures.

People with more severe sleep apnea do more often need higher pressures on CPAP or even bilevel therapy. This is especially true in the setting of obesity or nasal obstruction. Children may require similar pressures to adults, despite the smaller size of their airways.

Factors Affecting the Pressure Setting

The anatomy of the upper airway and the nature of the airway obstruction has the biggest role in determining the required CPAP pressure setting.

If sleep apnea occurs because of a blocked nose due to allergies or a deviated septum, a collapsing soft palate, or a tongue that falls back into the airway, differing amounts of air are required to push these tissues out of the way.

In addition, being overweight or obese may exacerbate things. In fact, when people lose about 10% of their body weight, it may be necessary to adjust the CPAP settings by turning them down.

Alcohol, medications that relax airway muscles (like benzodiazepines), and sleeping on your back may all transiently add to your pressure needs. Finally, REM sleep towards morning may relax muscles and exacerbate sleep apnea as well.

Making Pressure Adjustments

Therefore, as described above, it is not easy to guess what CPAP pressure you may need to treat your degree of sleep apnea. It may also vary somewhat during the night depending on your sleep position and sleep stage.

If the pressure is too low, your sleep apnea will not be adequately controlled. If it is too high, you may experience side effects like mask leak or air swallowing. It is important to have the machine properly set by a sleep specialist to ensure the best experience with it and the greatest benefits.

Modern devices can provide information on the residual AHI and this can help to guide the pressure adjustments. It may be desirable to use an AutoCPAP machine that is able to adjust with these other variables.

A Word From Verywell

If you continue to have sleep apnea symptoms, get reassessed by your board-certified sleep medicine physician to ensure your condition is adequately treated by your machine’s pressure settings. Don’t change the settings yourself as you may not fully understand the variables that contribute to the difficulties you may be experiencing.

What a Ramp on CPAP Is

Most modern CPAP or bilevel machines have a comfort setting called a ramp. As the word implies, it allows the machine to start at a lower pressure and then gradually to increase the pressure over a set period.

The beginning of the ramp, with lower pressure, may make it easier to fall asleep. Once you have fallen asleep, the pressure can be increased to the range that is needed to keep your upper airway from collapsing during sleep.  

How the Ramp Is Set on CPAP

There are multiple PAP machine models available from distinct manufacturers and various iterations over the past decades. Not all have a ramp feature, and the ability to access it will vary based on the model.   It may be easiest to review your device’s manual or to speak with your durable medical equipment provider or sleep specialist to access the setting.

In general terms, the ramp may begin when the machine is turned on, and it may be initiated via a reset button on the external surface (often with a triangle on it). Its settings may also be a feature that is accessed via a user menu on the device’s display screen. The initial pressure and duration of the ramp may be preset by your provider or be accessible to you.

There are two variables to consider in the ramp setting. First, the starting pressure should be comfortable. It is generally lower than the pressure that may be required later to support your breathing once you’ve fallen asleep. The lowest possible ramp setting is 4 centimeters of water pressure (CWP).   If it is set too low, you may struggle to get enough air and may request that it be turned up.

Second, the duration of this starting pressure will vary in 5-minute intervals from zero (if off) to 45 minutes. This duration should be slightly longer than the average amount of time it takes you to fall asleep.

If you feel the pressure becoming stronger, your ramp is likely too short. In addition, newer devices may have an automatic ramp feature that detects changes in the regularity of your breathing with the onset of sleep as an indicator that the pressure can be turned up.  

Using a CPAP Ramp and Overuse Issues

It is advised to use your ramp to help ease yourself into sleep without having to contend with an uncomfortable pressure.   Once the ramp ends, the device will increase to your lowest therapeutic pressure (which may be either fixed or further adjusted during the night as needed with an AutoCPAP or Autobilevel machine).

If you wake in the night and the pressure has become uncomfortably high, it is possible to reset the ramp and allow the pressure to be lowered again. This may be desirable if you have awakened for any reason, including to urinate.

It may also be helpful if your mask has started to leak excessively and has become disruptive due to noise or the discomfort of the airflow. This will allow you time to fall back asleep at a lower, more comfortable pressure.

It is possible to overuse your ramp, and this can cause some problems.   When reviewing your usage data, your sleep specialist may note multiple ramp resets throughout the night. This might suggest the presence of excessive mask leak, pressure levels that are too high, or coexisting insomnia.  

Repeated resets of the ramp can reduce the effectiveness of therapy.   If you require a pressure of 10 CWP to support your breathing, and you consistently reset your ramp to 4 CWP for 45-minute intervals through the night, you will have long stretches when your sleep apnea is not adequately treated.

For those who are needing to reset the ramp repeatedly, think about the underlying cause. If you are waking to urinate, or due to mask leak, address these underlying problems. You may benefit from a mask fitting to explore a new option. In some cases, it may be necessary to switch to ​bilevel therapy, as this treatment can make it more comfortable to breathe both in and out.  

Speak with your equipment provider or a sleep specialist if you need additional assistance in optimizing the settings of the ramp on your PAP machine.

It’s an undisputed fact that continuous positive airway pressure, or CPAP, therapy is the number one form of treatment for sleep apnea. A CPAP machine provides continuous pressured air through a hose and mask that keep obstructions from blocking the airways when you sleep, essentially “curing” the condition when under use. When your breathing becomes normal again, the body ceases to wake itself up, allowing for more restful, deep sleep throughout the night.

Your Pressure Settings

Restful sleep can only happen if your pressure settings are accurate and properly prescribed by a board-certified sleep physician. Your personalized pressure settings are based on a variety of factors from age, gender, and weight to things like sleep positions and environmental factors. Severity of sleep apnea alone does not determine the pressure settings on your CPAP machine.

Pressure settings on your CPAP machine can be a bit difficult to understand if you don’t do your research. Your CPAP pressure settings are measured in centimeters of water pressure, or cmH2O. Most CPAP machines are able to go as high as 25 cmH2O, but that is far too high for the average sleep apnea sufferer. While the average setting is 10 cmH2O, your setting will likely fall anywhere between 6 and 15 cmH2O. Again, your pressure settings are prescribed by your sleep physician based on the results of your sleep study as well as the type of machine you are recommended to use: a CPAP, BiPAP (BiLevel Positive Airway Pressure) or AutoPAP (Automatic Positive Airway Pressure).

How to Tell When Your Pressure Needs Adjustment

If you have a CPAP machine , you use one pressure setting prescribed by your doctor for the entire night. Your pressure should be just enough to keep your airways unobstructed for a full night of sleep. When your pressure is too low, you can experience more apnea events than the normal 5 per hour as well as other symptoms like snoring or waking up gasping for air. But, if the pressure is too high you can experience other side effects like uncomfortable therapy, problems with your CPAP mask, nasal congestion, and fitful, interrupted sleep.

BiPAP pressure settings deliver air at two different pressures: one for inhalation and another for exhalation. These different pressures help hold your airways open when you breathe in but produce a lower pressure so you can more comfortably breathe out. As such, if your physician prescribes a BiPAP machine, you should also get two different pressure settings. If these settings are too low or too high, you will experience the same symptoms as those with incorrect CPAP settings.

An AutoPAP machine is a bit different in that it automatically adjusts the pressure itself, changing to adapt to your breathing patterns as they change throughout the night. Some sleep apnea sufferers tend to experience increased breathing events at certain times of the night or during certain points during their sleep cycle. An AutoPAP machine takes these factors into account and vacillates between different pressures within a range prescribed by your doctor. Again, if the pressure range changes to be too low or too high for your condition, you’ll experience similar symptoms to those in the above two machine types. This auto-adjustment may lead to fewer pressure changes as its inherent adaptability makes it a less rigid type of sleep apnea treatment.

If you are ever concerned that your sleep apnea treatment settings are too low or two high for your condition, please consult your sleep physician before making any changes to the settings. Incorrect pressure settings can lead to worse sleep and less effective treatment, causing even more problems in the long run. Ensuring that your machine and specialized pressure settings are correct is an important step to managing your sleep apnea and experiencing the better quality of life that restful sleep can bring.

Speak with your equipment provider or a sleep specialist if you need additional assistance in optimizing the settings of the ramp on your PAP machine.

Auto CPAP machines (APAP) automatically adjust the pressure settings throughout the night based on your individual needs. How does an APAP machine work? It uses an algorithm that detects airway closure, increasing or decreasing as needed. This technology is great for people who change sleep positions, which can cause apnea to be more severe and require a higher pressure. These sleep apnea machines are perfect for correcting breathing problems and promoting better quality sleep.

Weight gain or loss can mean that you need a pressure adjustment, and the auto CPAP machine will do that for you without the need of undergoing another sleep study for pressure adjustment. That is the main difference between the auto CPAP machines and the average CPAP machines. These devices have a pressure range of 4 to 20 cm/H2O and can be set to auto mode or fixed pressure mode. One of the most loved machines by people with sleep apnea is the Philips Respironics CPAP machine. Another favorite is the ResMed AirSense 10 with its built-in humidifier and ClimateLine. No matter what brand you opt for, their machines provide the necessary therapy for breathing problems that hinder you from a good sleep.

Frequently Asked Questions

What Does an APAP Machine Do?

An auto-adjusting airway pressure machine (APAP) is a smarter breathing device that adjusts perfectly to your body’s ideal pressure through a breath basis. It detects varied pressure during drastic weight loss or gain, consuming alcohol before going to bed, or even changing sleeping patterns throughout the night.

This is done through the therapy-tracking software that comes with the device and, unlike the original machines CPAP are known for, it’s not programmed to do only one single air pressure. It can also run on an off-grid power option and offers heated humidification when needed. It’s a better alternative for those who have fluctuating weight or those who can’t sleep in one position.

What Is the Difference Between APAP and CPAP?

The original continuous positive machines are only capable of a single pressure that is covered for different people with sleep apnea. The only setting it offers is the highest setting, which is the necessary pressure that’s usually used in sleep studies.

Since there are different factors that need to be understood first before identifying the setting, the auto-adjusting CPAP machine aims to be more flexible and provide the best pressure for your body. It’s easier to breathe and more comfortable to use compared to the standard continuous positive airway pressure you’re used to.

What Is the Best APAP Machine?

As of now in 1800CPAP, the best sellers the patients love to use are the ResMed AirSense 10 AutoSet with Humidifier & ClimateLine, Philips Respironics DreamStation APAP with Heated Tube Humidifier, and the SleepStyle APAP Fisher & Paykel CPAP machines. Depending on your budget and the kind of pressure you might need while sleeping, it’s all up to your needs and what you think is important for you.

Some people also factor in the size, as it’s necessary to carry this device during travels for continuous therapy. If you’re unsure what device to get, it’s safer to consult your sleep doctor first.

How Much Is an APAP?

It can cost as much as $999, depending on the brand, features, size, and functions. The cheapest in our store would be the mini APAP Transcend 3 by Somnetics ($449), which is made for traveling.

I will be traveling to Macchu Picchu in Peru. the elevation in the city of Cuzco where we will be staying for a few days is about 11,000 feet above sea level. How will this affect the operation of my CPAP?

Answer

The CPAP machine is affected by a change in altitude, so it will operate differently at higher altitudes such as Macchu Picchu. As you go up in the mountains, the air is thinner and is less air pressure than on the sea level.

The higher the altitude the less pull gravity exerts on the air molecules, therefore the air pressure decreases.

Some people think that if you have less air pressure to press on the airway, the pressure required to keep the airway open should also decrease.

But here is the catch: the CPAP delivered pressure varies directly with the change in air pressure at various altitudes. The higher you go on the mountain, the bigger the pressure drop in CPAP delivered pressure.

In other words, with less air pressure around you, the CPAP machine gives less pressure to open the airway .

Therefore, you will need to increase the CPAP pressure according to those 11,000 feet above sea level. Here is the study which proves that CPAP mask pressures varies systematically with changing altitude.

Fortunately, the new CPAP machines can automatically compensate for altitude changes. Still, I would recommend talking with your CPAP provider or sleep doctor regarding the automatic pressure adjustment for your altitude.

If your CPAP doesn’t have an automatic function, you may need to adjust it manually, but do this with your doctor. There are some calculations to be made for manual adjustment.

However, given the large changes in altitude and the small changes in pressure, I would think that making changes on one’s own would be a risky proposition.

Another issue that can happen to some CPAP machines at higher altitudes is a false leak detection, obviously due to low ambient pressure at this high altitude. The pressure sensor is causing the CPAP to shut itself off every few seconds because of this alarm. Hopefully, if you have a good machine, it won’t happen to you.

Bottom line. I would suggest you talk to your sleep specialist about your trip on high altitudes.

Even when the CPAP is making the automatic adjustment for altitude, you can still have problems. It all has to do with the thinner air which does not have as many oxygen molecules.

The brain does not get the signal to breath and you may get central apnea events. even with the use of CPAP. One remedy is to adjust your pressure..not to be done without a doctor’s knowledge. Another remedy is to use supplemental oxygen.

I hope it helps. Don’t be afraid to comment back.
