What is the Difference Between CPAP and BiPAP Therapy?

March 01, 2022 | Sleep Apnea |

CPAP therapy and BiPAP therapy both apply to sleep apnea patients. Here are the similarities and differences between both types of therapy and the machines you may have to use.

Difference between CPAP vs BIPAP

What is CPAP?

CPAP stands for continuous positive airway pressure. Sleep apnea patients have a tendency for their airways to close, leading to disruptive and unhealthy sleep patterns. This treatment for sleep apnea uses mild air pressure to keep your airways open while you sleep.

What is BiPAP?

For some patients, mild air pressure isn’t enough. BiPAP or bilevel positive airway pressure delivers pressurized air both during inhalation and exhalation, regulating settings prescribed by your sleep doctor. BiPAP is used for more severe sleep apnea cases, other health conditions, or for sleep apnea patients who have been unsuccessful with CPAP.

What are the Similarities Between CPAP vs BiPAP?

Both CPAP and BiPAP therapies use pressurized air to treat sleep apnea. They both therapies use machines with a hose and mask to deliver that pressurized air. Both  CPAP machines and BiPAP machines are available with humidifiers. Both machines are also available in portable versions.

What Health Conditions do CPAP and BiPAP Treat?

 CPAP therapy is focused entirely on managing sleep apnea. BiPAP therapy is also used for patients with congestive heart failure, coronary artery disease, and pulmonary lung disease like COPD. With regulated pressures for both breathing in and out, BiPAP becomes helpful for patients with low oxygen levels.

What is the Difference Between BiPAP and CPAP?

CPAP machines deliver pressurized air through the nostrils into the back of the throat to maintain an open airway while you sleep. While the air pressure is adjustable, the CPAP machine is delivering only one flow of air.

BiPAP machines deliver two levels of air pressure, inhalation positive airway pressure (IPAP) and exhalation positive airway pressure (EPAP).  These two adjustable pressure settings provide a more regulated control of airflow for patients.

Which is Better: CPAP or BiPAP and Why?

There are many factors that can determine which type of machine will be better for you. It is important you first consult with your doctor so they can give you an accurate diagnosis of how severe your sleep apnea is.

Although the type of therapy you end up using depends on your personal health needs as recommended by your doctor, your personal comfort matters too. If you are struggling to adjust to CPAP, BiPAP may be the ideal alternative for a more restful sleep. The most important thing is to prioritize getting the best therapy necessary for a successful night’s sleep and better health overall.

How Much Does CPAP or BiPAP Cost?

CPAP is less expensive with CPAP machines ranging from $385 to $849. If BiPAP therapy is required, you will pay more with BiPAP machines running from $1,700 to $3,500.

    I snore like a train, will a cpap help me.

      Hi Michael, snoring could be a potential sign of sleep apnea. We recommend first getting tested for this disorder, and a doctor would then be able to prescribe you to CPAP therapy if needed. Sleep Care Online is a great at-home sleep study we recommend that you can take from the comfort of your own home.
