    Common CPAP Machine Questions

    What is a CPAP Machine? What is CPAP Used For?

    CPAP machines are a way to treat Sleep Apnea. CPAP is an acronym that stands for "Continuous Positive Airway Pressure" and is regarded by experts as being the best way to treat Obstructive Sleep Apnea. Sleep Apnea is a sleep disorder where a person's upper airway relaxes during sleep, and in this relaxed state partially or completely blocks the airway. These blockages can cause the person to wake up as the body fights to breathe. If this process happens hundreds of times a night, not only does one not sleep well, but they also have increased chances of higher blood pressure, and are at greater risk for heart attack or stroke.

    To begin treatment, a person would see a Sleep Specialist or other medical professional. In most cases, they would order a sleep study as a diagnostic tool. The sleep study would check heart rate, blood oxygen levels, and breathing among other things. The results of the sleep study help determine what type of treatment the doctor will pursue, which may include wearing the CPAP pressure machine. Popular brands of CPAP devices include Resmed, Philips Respironics, Fisher & Paykel, Human Design Medical, 3B Medical, and DeVillbis.

    How Do CPAP Machines Work?

    PAP machines have an internal motor which provides air pressure at a specific pressure setting, helping keep the airway open throughout the night, assisting in getting an adequate amount of oxygen to the lungs. This means less choking, gasping, and waking up during the night. It means better sleep, and your body isn't deprived of the oxygen that it needs to keep you healthy. CPAP devices are mostly quiet (under 30 decibels) and some are very small and lightweight - designed with busy lives in mind.

    CPAP machines only work with the help of a CPAP mask. CPAP masks come in three basic styles: full face masks, nasal masks, and nasal pillow masks. Full face masks cover the nose and mouth. Nasal masks cover the entire nose. Nasal pillow masks are so-called because they use soft nasal pillows, sealing around the base of each nostril. While people breathing through the nose can use any mask, mouth breathers will need to use a chin strap in order to use a nasal or nasal pillow mask.

    What are the Differences Between CPAP, BiPAP and APAP Machines?

    CPAP machines have 3 different types to choose from, designed to fulfill 3 different needs:

    • CPAP Devices: Only blow air at one set pressure ranging from 4 - 20
    • APAP Machines: APAP machines blow air at a variable pressure on a breath-by-breath basis ranging from 4 - 20
    • BiPAP Machines: BiPAP machines (also known as BiLevels) provide different pressures for inhalation and exhalation ranging from 4 - 25, and can automatically adjust on Auto-Adjusting BiPAPs

    The type of machine you get depends on what your prescription says. For example, a prescription for a CPAP machine cannot be used to purchase a BiPAP machine, and vice versa. A prescription for a CPAP machine CAN be used to get an APAP machine. It all depends on how severe your condition is and whether you have complications like Complex Sleep Apnea or Central Sleep Apnea.

    What Are the Best CPAP Therapy Devices?

    That's a really good question, and if you look at current buying trends, the best CPAP machines right now are actually APAP machines! Like we mentioned earlier, APAP machines blow air at a variable pressure on a breath-by-breath basis. This makes them so much more versatile than CPAP machines, and it's a large reason why APAPs are preferred by most patients. Some customers are also interested in travel devices. Travel devices are almost always APAP machines. As the popularity of travel machines increases, we will only see further growth of the APAP machine category.

    Where to Get a CPAP Device?

    CPAP therapy devices are considered Class II Medical Devices and are available from CPAP shops called Durable Medical Equipment providers. CPAP machines are also available at online DMEs, like In order to get one, you need to get a prescription from your doctor. Typically, a doctor would conduct a test known as a sleep study to look at your heart rate, breathing, and blood oxygen levels. Sleep studies are typically done at home or overnight in a Sleep Lab. Home Sleep Tests are growing in popularity and use an electronic device that records your activity. In the morning, you would mail it back to the Sleep Lab and wait for your results. When the results come in, your doctor will know if a CPAP is right for you.

    When you get a CPAP device from an insurance company, one thing to watch out for is how much you'll get billed for the total cost. Depending on how your policy is written, there could still be a cost even if you've met your deductible. The total cost can be higher when you get a machine through your insurance company. Insurance companies also get reimbursed the same whether you get a great machine or an average one, so there's little incentive to give you the best machine.

    Is CPAP Therapy Loud?

    CPAPs are not as loud as you might think. Even though the device motors are a distant cousin of vacuum motors, manufacturers have gone to great lengths to make machines quiet. Many CPAP devices check in at 30 decibels or less, which is considered whisper-quiet. When paired with a quiet mask, it can reduce the overall sound output to a level that will allow you to comfortably sleep.

    What's it Like to Sleep With CPAP Therapy?

    Sleeping with a CPAP device can feel a little unusual at first, but your body will adjust quickly to the increased pressure, and soon you won't notice the change in pressure. If you notice air escaping from the side of the mask or air blowing on your face, many masks can be easily adjusted to minimize the discomfort. Many CPAP users use humidification to reduce the dry mouth or nose sensation that can happen when using CPAP therapy. Once you start using your machine every night, you'll begin to notice benefits that will improve your everyday life. You may find any annoyances with your therapy are easily outweighed by the benefits.
