As the legend goes, a country doctor named Dr. Allen DeVilbiss first invented an atomizer designed to help his patients breathe easier in his backyard tool shed in 1888.
From humble origins in the doctor’s backyard, DeVilbiss Healthcare has grown into a global leader in respiratory medical manufacturing. Today, DeVilbiss designs, manufactures, and distributes respiratory therapy devices and medical technologies to more than 100 countries around the world. The company’s commitment to technological advances in the respiratory therapy world has earned them an A+ rating from the BBB.
DeVilbiss Healthcare manufactures a line of state-of-the-art Continuous Positive Airway Pressure (CPAP) machines. Widely regarded as the most effective way to treat obstructive sleep apnea (OSA), CPAP devices deliver pressurized air through the nasal passages to help users breathe easier during sleep.
In this guide, we’ll discuss the five different models of DeVilbiss CPAP machines, including the IntelliPAP Standard, Standard Plus with SmartFlex, AutoAdjust, Bilevel S, and AutoBilevel. To help you identify the right device for your individual needs, we’ll compare specs and explain the differences in their technologies.
The first and least expensive member of the IntelliPAP CPAP series, the DeVilbiss IntelliPAP Standard boasts the same compact design and many of the essential features of the later models. Like all four models, the DeVilbiss IntelliPAP Standard CPAP machine includes an optional heated humidifier that can be attached to form a single unit.
Sophisticated, compact construction designed to be quiet, discreet, and travel-friendly
User-friendly interface naviated with three large buttons
SmartCode feature tracks sleep performance and generates reports on therapy and usage data over 1-day, 7-day, 30-day, and 90-day periods
Least expensive model
Lacks more advanced features of later models, like event detection and SmartFlex exhale pressure relief
Data reporting limited compared to other models, lacking Expiratory Puff Index (EPI), Non-Responding Event Index (NRI) and (Apnea Hypopnea Index AHI) reporting
IntelliPAP Standard Plus with SmartFlex
The IntelliPAP Standard Plus takes comfort a step further with the introduction of SmartFlex, a technology that helps relieve machine pressure as you exhale. The SmartFlex system incorporates three levels of pressure relief and six different inspiratory and six rounding options to customize transitions between inhaling and exhaling.
SmartFlex technology helps you to breathe easier and limit sudden pressure changes that cause disruptions in sleep
SmartCode Tracking system records advanced therapy data on hypopnea, apnea, exhale puff events, and more
SmartCode data can be retrieved remotely
Some customers report FlexFlow function feels initially strange and requires getting used to
The versatile IntelliPAP AutoAdjust can function both as a traditional fixed-pressure CPAP machine and an auto-adjusting device. The auto-adjusting feature relies on an algorithm to learn your breathing patterns and changes pressure in response to hypopnea, expiratory puffs, and other events and conditions during the night.
Offers optional self-adjusting mode that automatically raises or lowers pressure on a breath-by-breath basis
Automatically detects mask leaks and snoring
Includes SmartFlex technology to provide exhale pressure relief and SmartCode data tracking
Some customers report high noise levels
IntelliPAP Bilevel S
Recommended for patients who require higher pressure to maintain open airways, the IntelliPAP Bilevel S machine offers a pressure range of 3 to 25 cm H20 compared to the 3 to 20 cm H20 of the previous three models. The Bilevel S can operate in traditional CPAP or in Bilevel mode, which delivers two different pressures for inhaling and exhaling.
Features optional bilevel mode with distinct pressure for inhalations and exhalations
Includes Flow Rounding technology designed to create more natural transitions in and out of inspiratory positive air pressure (IPAP) and expiratory positive airway pressure (EPAP)
No auto-adjusting setting
The newest IntelliPAP machine from Devilbiss Healthcare, the IntelliPAP AutoBilevel combines traditional CPAP with auto-adjusting and bilevel technologies into one machine. On auto-bilevel mode, the system utilizes an algorithm to self-adjust pressure on both inhalation and elation.
Operates as traditional CPAP, auto-adjusting, bilevel, or auto-bilevel device
Wider range of pressure settings
Includes SmartCode data tracking and Flow Rounding technology
Most expensive model
Which DeVilbiss CPAP machine will work for me?
The IntelliPAP machines are virtually identical in size and design, and all offer an optional attached humidifier. Choosing from the different models largely comes down to determining whether traditional CPAP, auto-adjusting, bilevel, or a combination of the three technologies is best for you. We’ve discussed these three different technologies and sleepers they are best suited for below.
CPAP: A traditional CPAP like the IntelliPap Standard or the IntelliPAP Standard Plus with SmartFlex delivers pressure at a set, predetermined pressure level through the night. This type of machine is generally recommended for sleepers with mild to moderate sleep apnea.
Auto-adjusting: Sometimes called an APAP or AutoPAP machine, an auto-adjusting device like the IntelliPAP AutoAdjust or the IntelliPAP AutoBilevel uses a complex algorithm to detect and adjust pressure as needed throughout the night. Auto-adjusting machines are recommended for those who tend to toss and turn during the night, as pressure needs may change depending on position. They’re also recommended to those with seasonal allergies, as pressure needs may change due to congestion during the night or according to the seasons.
Bilevel:Sometimes referred to as BiPAP machines, bilevel devices like the IntelliPAP Bilevel S or the IntelliPAP AutoBilevel deliver two different pressures: one corresponding to inhalation and one corresponding to exhalation. Like many Bilevel devices, the two IntelliPAP machines with bilevel modes feature a wider pressure setting range. Bilevel machines like these are recommended to patients who with higher inhalation pressure needs, since exhaling over high pressure can be difficult.
Even if your pressure needs are not high enough to require a bilevel device, you may want to skip the IntelliPAP Standard if you find that exhaling while wearing a CPAP device can be challenging or uncomfortable. In addition to having more limited data reporting, the IntelliPAP Standard is missing the SmartFlex exhalation pressure relief feature of the other two non-bilevel devices.
