Bilevel positive airway pressure (BiPAP), also now and again known as BPAP, is a mechanical respiration device with a masks that is used to deal with sleep apnea and other health situations that impair breathing.1 This consists of positive instances of COVID-19 in which BiPAP can be used to postpone mechanical air flow.2
BiPAP is a less commonplace opportunity to non-stop high quality airway pressure (CPAP) but, in a few conditions, can be more useful. For instance, wherein CPAP gives steady air pressure, BiPAP offers various stress in the course of inhalations and exhalations. This can be beneficial for humans who’ve hassle exhaling towards CPAP’s continuous strain.
This article explains how BiPAP is used to treat obstructive sleep apnea and principal sleep apnea.What BiPAP Does
A BiPAP device is used whilst you could breathe for your very own, but require some help pushing air into your lungs so that you keep healthy oxygen degrees. It is used in scientific settings, as well as at home.
Much of a BiPAP device is the same as the same old CPAP machine. For instance, it nevertheless calls for a face mask and tubing linked to the device. But there are a few variations among BiPAP and CPAP.
The pressurized air settings of the BiPAP include:1
Inspiratory superb airway strain (IPAP): This is the strain the system affords as you inhale. The BiPAP presents a higher IPAP than the CPAP. So, when you inhale, the BiPAP helps your breath as you are taking it in.
Expiratory fine airway pressure (EPAP): This is the strain the gadget presents when you exhale. The BiPAP offers a decrease pressure that permits you to breathe out readily.
BiPAP pressures are preset based totally on your health practitioner’s prescription. They trade just like your respiratory pattern.
Beyond these wellknown settings, there are some different to be had variations. They include:4
Bilevel ST: This consists of the timed shipping of a breath if the gadget detects a pause to your breathing. These pauses often arise in valuable sleep apnea.
Auto or adaptive servo-air flow (ASV): These superior settings range the timing, period, and volume of the breaths the gadget supplies.

When BiPAP Therapy Is Used
BiPAP is a form of respiratory guide that treats crucial sleep apnea (CSA). CSA takes place while the mind does not ship right signals to the muscular tissues that manage respiratory, causing prolonged gaps n breathing.
The reason of CSA is not always recognised but is occasionally seen in human beings who’ve:four
Neurological issues like Parkinson’s sickness and more than one system atrophy
Sleep-disordered breathing due to opioid drug use
Congestive coronary heart failure (CHF)
Doctors can also prescribe it for extreme instances of obstructive sleep apnea (OSA). This is the more common sort of sleep apnea that happens when your higher airway receives in part or completely blocked.5
As opposed to CSA that’s neurologic (related to the brain), OSA is as a result of a mechanical trouble that blocks the airlines, which includes continual obstructive pulmonary disorder (COPD) and pulmonary edema.Three
BiPAP is useful whilst there’s mixed sleep apnea, that means that there are components of each CSA and OSA.
Cost of BiPAP Machines
BiPAP is more highly-priced than a general CPAP device. It can be two or three times the cost of a CPAP. The ASV models can fee more than $4,000.
In addition to treating relevant sleep apnea, BiPAP is likewise useful inside the following situations:
People who’ve hassle with CPAP: People who have trouble respiration out in opposition to CPAP pressure may additionally advantage from BiPAP. This is especially real for individuals who require better stress—normally higher than 15 centimeters of water stress (CWP)—to hold the airway open.4
People who are hospitalized: BiPAP is a non-invasive treatment for those who are in respiration misery however who need to be on a mechanical ventilator. This may be the case for people with respiratory headaches of COVID-19.2
People with neuromuscular disease: It may be useful in those with conditions that reason nerve and muscle weakness, including amyotrophic lateral sclerosis (ALS).5
What Is a Sleep Study (Polysomnogram)?
BiPAP vs. Bilevel vs. VPAP
There is some confusion about the word BiPAP, bilevel, biphasic, BPAP, and VPAP (variable fantastic airway stress). They are all basically the same factor. However, the names of the device range particularly based totally at the manufacturer.
They consist of:
Respironics: One of the main producers of these devices, Respironics, has registered BiPAP as a hallmark call for the generation generically called bilevel.
ResMed: The other important competitor, ResMed, calls similar gadgets VPAP.
AirCurve: ResMed also markets AirCurve that’s a bilevel device.
Though the names can be unique, the basic concepts are the equal.
In most instances of obstructive sleep apnea, CPAP alone is enough as a therapy. However, BiPAP can be an excellent opportunity within the extra complicated scenarios or when it’s miles tough to tolerate CPAP.
A Word From Verywell
BiPAP is an alternative to CPAP to deal with people with relevant sleep apnea. In addition, those who cannot tolerate CPAP and those hospitalized with respiratory misery who do no longer want to be on a ventilator may additionally choose BiPAP.
If you marvel whether BiPAP might be suitable for you, start with the aid of speaking with your sleep doctor. After they compare your chance factors and sleep look at, they can recommend the proper treatment.
FREQUENTLY ASKED QUESTIONS
How long are you able to live on BiPAP?
In theory, you can be on BiPAP indefinitely. Even so, the tool isn’t always meant for use complete-time within the same manner as supplemental oxygen remedy for people with COPD. Using BiPAP continuously for longer than 24 hours can reason pressure ulcers, severe nasal tissue injury, or even tissue demise.6
Can BiPAP damage the lungs?
Lung damage isn’t a diagnosed difficulty of BiPAP.7
What is the distinction between BiPAP and a ventilator?
BiPAP is a machine used to deal with sleep apnea and different conditions wherein someone remains capable of breathe however needs assistance is needed. Mechanical air flow is used when someone can not breathe well sufficient on their own to aid the body’s need for oxygen.
