The Difference Between CPAP and BiPAP

A CPAP machine is a type of air pressure machine which provides constant air pressure. It has two parts: a blower and an air tube. The prescription specifies the settings for the blower and the tube’s length, diameter, and pressure.

A BiPAP, on the other hand, is a type of sleep apnea device that provides individualized therapy for each patient’s needs. Unlike CPAP devices that provide fixed levels of therapy provided by a single-level device, BiPAP machines are multi-level – they offer different levels of therapy to suit each patient’s needs.

The ResMed BiPAP machine by No Insurance Medical Supplies machine is a device that helps to treat sleep apnea. It works with the help of a mask. The CPAP is used for patients diagnosed with sleep apnea, and the BiPAP is for those who have not been diagnosed but may have mild sleep apnea symptoms.

What is CPAP?

CPAP is an abbreviation for “Continuous Positive Airway Pressure.” For obstructive sleep apnea, it is the gold standard treatment option (OSA). A machine creates pressurized air, which is then piped into a mask and placed over the user’s nose and/or mouth.

How does it work?

To maintain an open airway, CPAP therapy employs a CPAP machine that pumps pressurized air past the patient’s nose and down the back of their throat. You can alter the level of pressure. Several variations of on-air delivery can keep the airway open when sleeping.

Who uses it?

Those who have severe breathing difficulties during sleeping often use CPAP therapy. Patients with obstructive sleep apnea, in which the lungs don’t get enough air, are the ones who benefit the most from this treatment for sleep apnea. This method of treating sleep apnea has been successfully used not only in adults but also in infants. To force air into the lungs of infants whose lungs have not matured, CPAP therapy is used.


What is BiPAP?

BiPAP stands for Bilevel or two-level Positive Airway Pressure. Similar to continuous positive airway pressure (CPAP), this sleep apnea treatment involves using a tube to provide air to a mask placed over the nose. Instead of only one pressure like CPAP does, BiPAP provides two, one for each breath. The terms “inhalation positive airway pressure” (IPAP) and “exhalation positive airway pressure” (EPAP) refer to the two different types of pressures that are applied to the airway during each breath (EPAP).

How does it work?

There are often two different levels of pressure that can be adjusted on a BiPAP system, and breathing effort is tracked. The BiPAP can be adjusted to administer a breath if the patient has gone without breathing for a predetermined amount of time. The minimum number of breaths per minute must be taken as a “backup rate” (BPM). The patient’s breathing rate is controlled such that they take the same number of breaths at the same rate every minute.

Who uses it?

People with severe cases of sleep apnea often benefit from this treatment because it provides them with the additional breathing assistance they require. Congestive heart failure/coronary artery disease and pulmonary or neurologic problems are common indications for its use. The pressure differential provided by a BiPAP machine may also be useful for patients with neuromuscular problems.

What is the difference between CPAP and BiPAP machines?

Positive airway pressure therapy often called CPAP and BiPAP equipment employs pressurized air to open and maintain the airway while you sleep. The pressurized air is produced by a portable machine and delivered to the user’s airway via a hose and mask. The masks, hoses, and other components of both systems are interchangeable.

The most effective CPAP devices allow the user to adjust the pressure, so that inhalation and exhalation air pressure is between 4 and 20 cm H2O (centimeters of water pressure). BiPAP devices offer two pressure settings that allow for reduced pressure during exhale: inhalation positive airway pressure (IPAP) and exhalation positive airway pressure (EPAP). The transition from IPAP to EPAP can either be timed or automatic, depending on the BiPAP machine’s settings and the individual patient’s breathing patterns. The standard pressure range for BiPAP equipment is between 4 and 25 cm H2O.

Although CPAP devices only have a single pressure setting, newer models with exhalation sensors can adjust the air pressure to be less harsh. Although the exhalation pressure is slightly lower than the overall pressure setting, unlike the EPAP setting on BiPAP devices, it is not adjustable by the user.

While BiPAP machines are intended for usage in the home, portable CPAP machines are ideal for trips. BiPAP machines are typically twice as expensive as comparable CPAP machines due to the need for additional sensors and settings.

Although there is some overlap, certain PAP therapies are more effective for different illnesses. Sleep doctors are unlikely to put a patient with obstructive sleep apnea (OSA) on BiPAP unless the patient is unable to tolerate CPAP. It is important to note that although some insurance companies will cover both CPAP and BiPAP for OSA, most of those companies will require evidence that CPAP treatment is insufficient before paying for BiPAP equipment. Central sleep apnea (CSA) and other conditions requiring structured airway assistance during sleep are treated with BiPAP.

There is a wide selection of built-in and after-market accessories for CPAP and BiPAP machines. Humidifiers, heated tubing, and other climate control systems are extremely prevalent.
