A clear BiPAP machine definition starts with its two prescribed air pressures: one for inhalation and another for exhalation. In other words, BiPAP is a common name for bilevel positive airway pressure equipment. A healthcare professional selects the device and settings based on a person’s clinical needs.
This guide explains how BiPAP equipment works and how it differs from CPAP. It also covers the device’s main components, what to consider when obtaining and using prescribed equipment, and questions to ask your healthcare professional or equipment supplier.
BiPAP Machine Definition: What Is a BiPAP Device?
A BiPAP machine is a type of positive airway pressure device that provides two pressure levels during a breathing cycle:
- Inspiratory positive airway pressure (IPAP): The pressure delivered during inhalation.
- Expiratory positive airway pressure (EPAP): The pressure delivered during exhalation.
Together, these two pressures define bilevel positive airway pressure. Depending on its features and intended use, a provider may also describe a BiPAP device as a bilevel machine or a non-invasive ventilation device.
“BiPAP” is widely used as a general term, although it is also a trademark associated with certain devices. However, equipment capabilities vary by model, so a healthcare professional must select and configure the device for its prescribed use.
BiPAP Machine Definition: How Does a BiPAP Machine Work?
A BiPAP machine draws in room air, pressurizes it, and sends it through tubing to a mask. As the person breathes, the machine supplies the prescribed pressure pattern. On a bilevel device, a healthcare professional sets the inhalation and exhalation pressures separately.
A typical setup includes the following components:
- The machine, which generates and controls airflow.
- Tubing, which carries air from the machine to the mask.
- A mask or interface, which directs air through the nose, mouth, or both.
- Optional humidification, which some systems use to add moisture to the airflow.
Specific features, operating modes, and accessories depend on the device. Therefore, follow the manufacturer’s instructions for setup, cleaning, and maintenance.
BiPAP Machine Definition: BiPAP vs. CPAP: What Is the Difference?
CPAP and BiPAP are both positive airway pressure devices, but they deliver pressure differently. Put simply, CPAP provides one prescribed pressure, while BiPAP provides separate pressures for inhalation and exhalation.
| Feature | CPAP | BiPAP |
|---|---|---|
| Pressure pattern | One prescribed pressure during use | Two prescribed pressure levels: one for inhalation and one for exhalation |
| Common equipment term | Continuous positive airway pressure | Bilevel positive airway pressure |
| Settings | The prescribing healthcare professional determines the pressure | The prescribing healthcare professional determines both pressure levels |
Neither device is automatically the right choice for everyone. Because the appropriate equipment depends on the prescription and clinical evaluation, the devices are not interchangeable. For more background on treatment options, see the National Heart, Lung, and Blood Institute’s overview of sleep apnea treatment. In any case, do not change a device, settings, or therapy without guidance from the prescribing healthcare professional.
What Are the Main Parts of BiPAP Equipment?
Machine
The machine generates airflow and applies the prescribed pressure pattern. Since controls and features vary between models, consult the manual for operating instructions.
Mask
Masks come in different designs. For example, some cover the nose, some fit beneath or around it, and others cover both the nose and mouth. Fit, comfort, breathing habits, and device compatibility may matter when you discuss mask options with an equipment supplier and healthcare professional.
Tubing
Tubing connects the machine to the mask. Use tubing that works with your specific device, and follow the manufacturer’s care and replacement instructions.
Humidifier
Some machines include or connect to a humidifier. However, whether you use humidification and how you operate it depend on the device instructions and your prescribed setup.
What Should You Know Before Getting a BiPAP Machine?
A healthcare professional prescribes BiPAP equipment. To obtain it, you may need a prescription, supporting documentation, and coordination among the prescriber, equipment supplier, and insurance plan.
Before the supplier provides equipment, consider asking:
- What prescription and documentation do I need?
- Which machine and accessories does the prescription specify?
- Which mask options work with the prescribed setup?
- How should I clean and maintain the equipment?
- Which replacement supplies work with this device?
- What costs might my insurance plan leave me responsible for?
Insurance coverage and patient costs depend on the individual’s plan and circumstances. A supplier may explain the equipment process and discuss insurance-related questions; however, no one can guarantee coverage or approval.

Using and Maintaining BiPAP Equipment
Use the machine and accessories according to the prescription and manufacturer’s instructions. Because cleaning steps and replacement intervals vary by model and component, check the device manual rather than relying on a schedule for another product.
If the mask, tubing, or machine looks damaged, or the equipment does not work as expected, contact the supplier for equipment-related guidance. On the other hand, contact the prescribing healthcare professional with questions about settings, therapy changes, or symptoms. Either way, do not adjust pressure settings on your own.
Frequently Asked Questions About BiPAP
Is BiPAP the same as CPAP?
No. CPAP provides one prescribed pressure, while BiPAP provides separate prescribed pressure levels for inhalation and exhalation. Therefore, do not treat the devices as interchangeable without appropriate clinical direction.
Does a BiPAP machine have two pressure settings?
A bilevel device uses an inhalation pressure and an exhalation pressure. In each case, the prescribing healthcare professional determines the settings for the person’s prescription.
Can I change my BiPAP settings myself?
No. Only change prescribed settings if the prescribing healthcare professional directs you to do so. If you have questions about your prescription or therapy, contact that professional.
Does every BiPAP machine use the same mask and supplies?
No. Compatibility depends on the device and its components. Therefore, check the equipment manual or ask the supplier to confirm that a mask, tubing, filter, or other accessory suits your specific setup.
Next Steps
In summary, a BiPAP machine definition describes a device that delivers two prescribed pressure levels through a machine, tubing, and mask. For that reason, the device, settings, and compatible supplies should match the prescription and manufacturer’s instructions.
