A BiPAP machine offers two levels of pressure, one for the patient's inhale and one for her exhale, and can help ease breathing for some patients. Patients may not understand the difference between CPAP vs BiPAP therapy and may want to learn why a change in therapy might be recommended, and what the benefits of BiPAP therapy are to improve sleep quality.

What Is CPAP Therapy?

One of the most popular treatments for OSA (Obstructive Sleep Apnea) is called Continuous Positive Airway Pressure (CPAP). Together, a CPAP machine produces a steady stream of pressurized air through a mask during sleep. This regular breathing keeps the airway open and does not cause pauses in breathing.

CPAP therapy can be helpful and alleviate symptoms for many people, including:

·        Loud snoring.

·        Poor sleep quality.

·        Morning headaches.

·        Daytime sleepiness.

·        Breathing problems during sleep.

But during breathing, CPAP provides exactly the same pressure for both in and out. If higher pressure is required, it may be difficult for some patients to exhale against the constant pressure.

What Is BiPAP Therapy?

BiPAP (Bilevel Positive Airway Pressure) therapy is a therapy that operates on two pressure settings:

·        Higher pressure when you breathe in (inhalation)

·        Lower pressure when you breathe out (exhalation)

This distinction can help make breathing easier and more comfortable for many patients. A BiPAP machine for sleep apnea can offer more breathing support for individuals who require more support than a CPAP machine can give.

Patients with certain sleep apneas, breathing problems, and those who need extra respiratory support are treated with BiPAP therapy.

CPAP vs BiPAP: Understanding the Difference

The primary difference between CPAP and BiPAP is the way that pressure is administered while breathing.

CPAP Machine:

·        Delivers continuous pressure level.

·        Mainly used for obstructive sleep apnea.

·        Supports respiration while sleeping.

·        Can be used for many mild to moderate cases.

BiPAP Machine:

·        Has 2 levels of pressure.

·        Inhales and exhales with support as needed.

·        Supports patients who require increased pressure support.

·        Helps to make breathing easier for some people.

There is no clear-cut advantage to either CPAP vs BiPAP. The best choice is based on the patient's condition, breathing habits and sleep study findings, and the doctor's advice.

Why Switch from CPAP to BiPAP?

Switch from CPAP to BiPAP might be considered if CPAP is not helping the patient and the patient requires more breathing assistance.

Some common reasons include:

1. Difficulty Exhaling Against CPAP Pressure

Others simply do not want to wear a CPAP machine. During exhalation, BiPAP decreases pressure, which can help breathing to be easier.

2. High CPAP Pressure Requirement

For those with severe sleep apnea, the pressure level might need to be increased. CPAP can be uncomfortable at higher pressures and BiPAP can offer an alternative to a more comfortable feeling.

3. CPAP Therapy Is Not Controlling Symptoms

If symptoms persist despite regular use of CPAP, a physician may choose to assess if BiPAP therapy might be more effective in supporting a patient.

4. Certain Breathing Conditions

A few diseases of the respiratory system may need a bilevel pressure support (BPS) instead of CPAP.

5. Improved Comfort and Compliance

Comfort is a key factor in a successful sleep therapy. Switching from CPAP to BiPAP can make it easier for a patient to use the machine nightly if they are having trouble with their CPAP.

When to Use BiPAP Machine?

Many ask that is the time to use BiPAP machine than CPAP. When you might use a BiPAP machine:

·        CPAP is not tolerated when it is not working.

·        If additional pressure support is required.

·        If a person experiences difficulties with breathing while asleep.

·        If patient needs help with breathing in and out.

·        When advised by a medical professional or sleep study after sleep problems are identified.

Decision regarding the use of BiPAP typically is made by a healthcare provider based on symptoms, sleep test results and general health.

Signs You Need BiPAP

If you know what signs to look for, you'll be better prepared to talk to your doctor about the options for treating your sleep apnea with BiPAP. The following are some potential indicators:

1. Feeling Tired Despite Using CPAP

Even when using CPAP regularly, people sometimes feel tired, have trouble focusing on tasks or lack energy during the day, and this can signal a need for CPAP evaluation.

2. Difficulty Sleeping With CPAP

Others experience discomfort breathing out against the pressure of the CPAP machine or may not get used to it.

3. Persistent Sleep Apnea Symptoms

If the snoring continues or breathing stops or is impaired, or if you don't sleep well, your current treatment might need to be adjusted.

4. Need for Higher Pressure Settings

If you need a higher pressure to use your CPAP machine, your doctor may want to try BiPAP, which may be easier to use.

5. Breathing Support Requirements

BiPAP therapy can be used for patients who require greater ventilator support.

Benefits of BiPAP Therapy

A proper therapy can help to enhance sleep quality and functioning in everyday life. Some benefits of BiPAP therapy include:

·        Better night's sleep.

·        Less pressure on the airways during exhalation than with high pressure CPAP.

·        Improved treatment of some breathing disorders.

·        Improved sleep quality.

·        Better quality of sleep due to reduced sleep apnea symptoms.

An apnea machine called BiPAP may offer more personalized breathing support for those who have difficulty using a CPAP machine for sleep apnea.

How Does a BiPAP Machine Work?

A BiPAP machine provides pressure support based on the pattern of your breathing by using sensors.

During inhalation:

·        The machine gives a higher level of pressure to help maintaining the airway.

During exhalation:

·        The pressure decreases, making breathing easier outwards.

This pressure gap decreases the effort needed for breathing and can help to make sleep more comfortable.

Is BiPAP Better Than CPAP?

This varies on a case-by-case basis. CPAP works for a lot of people who have obstructive sleep apnea, and BiPAP may work for people who require more assistance.

The choice of CPAP or BiPAP should depend upon:

·        Sleep study results.

·        The amount of oxygen deprivation or lack of breathing during sleep.

·        Breathing patterns.

·        Have confidence in ongoing treatment.

·        Doctor’s recommendation.

A BiPAP machine is not necessarily a CPAP machine; it is another therapy option that can be used for certain needs.

What Happens During the Switch from CPAP to BiPAP?

An oral doctor's prescription to change the therapy typically involves:

1.     You should always examine your existing CPAP data.

2.     Checking your sleep study reports.

3.     Adjusting pressure settings.

4.     Choosing the appropriate BiPAP machine and mask.

5.     Checking how you feel and are getting better.

Adjustment is necessary as incorrect settings can diminish the effectiveness of treatment.

Choosing the Right BiPAP Machine

When choosing a BiPAP machine, take into account:

·        Doctor’s recommendation.

·        Pressure requirements.

·        Comfort features.

·        Mask compatibility.

·        Machine settings.

·        Regular maintenance needs.

Long term therapy can be more manageable and effective with a suitable machine.

Conclusion

Switch from CPAP to BiPAP for those who are unable to get them to get a comfortable and effective seal at CPAP can be an important step. Knowing about CPAP vs BiPAP, the Difference between CPAP and BiPAP, and the Signs you need BiPAP can help patients make informed decisions about their sleep health.

BiPAP therapy delivers a two level pressure support that can make breathing easier for some and provide more comfort. However, if it is not tolerable, or symptoms persist, see a health care provider to find out if a machine that delivers air pressure during sleep (BiPAP) is the best machine to use for sleep apnea.
