Learn More About Your New Machine

The ResMed S8 Elite II is equipped with Easy-Breathe Technology along with new software, The CPAP now has a quieter motor and an improved EPR (Expiratory Pressure Relief) mode. The Easy-Breathe Technology is a new level in comfort and quietness. Use Version 3.5 or greater ResScan Software to check therapy effectiveness, compliance data, and periodic trends.

  • Users can choose a fixed CPAP pressure or an EPR mode 1 to 3 for maximum comfort with control. Adjusting the EPR settings allows the Easy-Breathe Technology to drop the pressure upon exhalation so that breathing feels more "natural". A pressure Ramp is also available and provides for a slow and comfortable increase to your pressure setting.

  • The S8 Elite II offers an improved motor that outputs only 24 decibels at 10cmH20 measured at one meter away. The S8 Generation One motors average 30 Decibels, making the new motors 75% quieter.

  • Fully customizable, the S8 Elite II has reminders for accessory replacements like your mask or machine filters. Take advantage of the remote downloading capabilities with the ResScan Data Card which provides comprehensive efficacy and usage data that helps you monitor critical trends on a breath-by-breath basis. The S8 Elite II allows for complete tracking and easy monitoring of patient therapy and compliance.

  • Compact and robust, the design of the S8 Series is portable and user-friendly, including Auto Altitude Adjustment to make sure the correct pressure is delivered when you travel.

  • The unit comes with a built-In power supply which automatically detects the DC input, which is ideal for travel. Please purchase the DC-12 Converter For S8 Machines.

  • Also included are the Ramp and settling options that enhance comfort and help improve compliance.


Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE the DC-12 Converter For S8 Machines when drawing power directly from a DC battery source (no inverter and no humidifier). Failure to do so can result in damage to your CPAP. ResMed S8 machines with a Humidaire heated humidifier (h3i and H4i) require a pure AC power source in order for the humidifier to work properly. The machine disables the humidifier when connected through DC Power. The machine and humidifier will both work properly only when connected to pure A/C power. You will need the DC to AC Pure Sine Wave Power Inverter to operate both.

User Manual:

The user manual included with this machine can be viewed and downloaded here: S8 Elite II User Guide.

Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE a cord such as the DC Converter for S8 Machines in conjunction with any battery source, when using an S8 or S8 II machine. Failure to do so can result in damage to your CPAP.

DC to AC Pure Sine Wave Power Inverter for Resmed S8 Machines

ResMed S8 machines are required to use a pure sine wave AC power source when connecting through an inverter; particularly, the ResMed S8 Compact is not DC compatible and must plug into a wall socket. The DC to AC Pure Sine Wave Power Inverter Second Gen provides clean AC power to any CPAP. You will need this product to operate the S8 Compact or any other S8 machine using the standard AC plug.

Cool Down Feature

All S8 and S8 II CPAP Machines utilize a "Cool Down" feature that runs the CPAP Motor up to 1 hour after turning the machine off. The motor helps to cool off the humidifier plate. You may hear a "faint blowing sound" when you turn the machine off. However, you can unplug the power cord and allow the heater plate to cool without airflow.

SmartStart

SmartStart enables your device to start automatically by breathing into the mask. Leak alert indicates when a high mask leak is present. If you have enabled Leak Alert, the SmartStart feature automatically becomes disabled. You cannot have both features enabled.

Humidification

The S8 AutoSet II and Elite II are compatible with the Humidaire 3i and the Humidaire 4i Heated Humidifier, but the CPAP machines were manufactured BEFORE the H4i was manufactured. When setting either machine, please note that H3i will appear on the display.

Leak Alert

Leak alert indicates when a mask is leaking as a result from a poor seal, open mouth or the complete removal of a mask. The alert is audible as well as visible on the machine's LCD display. This is one of the loudest and audible alerts on the market!

Universal Power

The S8 Series CPAP machines operate automatically between 110v and 240v AC. When traveling either inside or outside the USA, there are no switches to switch or fuses to change. The machine will automatically sense what voltage is needed and set itself to run on that power.

The user will need to adapt the plug that goes into the wall to fit the style of outlet socket that is being used. This is simply done with a Power Adapter Plug kit. This is the same type of plug adapter that would be used with a hair dryer or an electric shaver. World Traveler Power Adapter Plugs.

What does CPAP therapy do?
CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. It is traditionally provided through a nasal mask that seals around the nose to maintain the pressure level.
Which CPAP masks work on which machines?

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:

  • ResMed AirFit™ N20 Nasal Mask
  • ResMed AirFit™ F20 Full Face
  • ResMed AirTouch™ F20 Full Face
  • ResMed AirFit™ P10 Nasal Pillow

When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

What comes with my machine?
Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP, APAP, and BiPAP machines do not come with a delivery system or mask. CPAP masks must be purchased separately.

To see the list of what specifically comes with each machine, you can Browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.

Do all CPAPs use filters?
Yes, all CPAPs use at least one filter that is usually a type of foam material and washable. Some CPAPs offer finer filtration with the addition of a disposable paper filter.

Cleaning and changing filters is the only maintenance required for a CPAP machine.

The filters are located at the back of the machine at the air intake.
Are prescriptions required for mask, machine, humidifier, and EPAP purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or EPAP therapy, including Provent and Bongo RX. You will also need a prescription to purchase the Nightbalance POSA device.


We provide many easy ways to get your prescription:

  • We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.
  • Fax your prescription to our toll-free fax number: 866.353.2727, or our international fax number: 713.541.7377
  • Email your prescription to cpap@cpap.com
  • Upload your prescription in your account, under the Prescriptions Section
  • Ask your doctor to fill out our prescription form. We have both a standard prescription form and an EPAP prescription form.


For more information on prescriptions, please see our Prescription Section of the Learning Center.


What is ramp?
The ramp button on a machine is a feature that allows for a gradual pressure build-up to your prescribed pressure. The feature is enjoyed by those with high pressures because it eases up to their pressure.
What is exhalation relief?
Exhalation relief is a comfort feature which reduces the air flow at the time of exhalation, making the breathing process more natural.

The following are the different types of exhalation relief names by manufacturer.

  • Philips Respironics = C-Flex, C-Flex+, A-Flex and Bi-Flex
  • Resmed = EPR (Expiratory Pressure Relief)
  • 3B Medical = RESlex
  • Apex Medical = PVA (Pressure Variation Algorithm) Pressure Relief
  • Curative Medical = EUT (Expiratory Unloading Technology)
  • DeVilbiss = SmartFlex
  • Fisher & Paykel = SensAwake Technology
  • Human Design Medical = Z-Breathe
  • Somnetics = EZEX

Here are some machines with an exhalation relief feature:

Transcend Auto miniCPAP™ Machine with EZEX
PR System One REMStar 60 Series Auto with Bluetooth
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier

What maintenance is required on machines?
The only care a CPAP, APAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.

Here are some other suggested actions to care for your machine:
  • Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
  • Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
  • If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
  • If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.

I had an older S8 and was happy with it. I have had light to moderate sleep apnea for 15 years and am comfortable with a nasal mask and no humidifier. I tried the most current models of both the Resmed and Respironics machines and found that the design, compactness, and noise factor of this model beat out the newer machines that are designed to be used with a humidifier.

S8 Elite II

Verified purchase | Sep. 01, 2011 | Verified CPAP.com Customer
I was a little nervous, buying a CPAP machine online. I thought it might be difficult to set it up myself - without the help of a technician. I was wrong. The setup was easy; the instructions understandable. Within just a few minutes it was working perfectly. I can't believe a CPAP can be this small and quiet.

Outstanding

Verified purchase | Aug. 19, 2011 | Verified CPAP.com Customer
Its small size makes traveling a breeze. Its super quiet and if you find the hidden menu to adjust air pressure, you can adjust it yourself if you get a cold and need more pressure. I wish it had a longer cord. I need to travel with an extension cord because hotels don't often have an outlet near the bed that is available and open. The air filters are ok, and rather extensive to replace. I found home depot has room airconditioner filters and if you get the ones that filter 'pollen' and/or pet dander, are the best. Its cheaper and works as a filter just as good.

Excellent CPAP

Verified purchase | Jul. 11, 2011 | Verified CPAP.com Customer
I got the S8 Elite II to replace my broken S8 Compact. It was easy to set up and runs very quietly. As a bonus it accepts my current Humidaire 3i humidifier so I didn't have to get a new one. I recommend this unit without reservation.

Nice Machine

Verified purchase | Feb. 09, 2011 | Verified CPAP.com Customer
Great machine. Adjusts pressure when you inhale and exhale. The humidifier does not hold enough water. The air tube needs to be heated to prevent condensation. The motor starts up and slows down when you breath which may annoy your partner. But you really get a good deep sleep with this machine.
