Learn More About Your New Machine

Packed with every feature ResMed offers, the VPAP series starts out with a wider pressure range, accommodating pressures from 3cm to 25cm H20 and supports five modes of operation (Spontaneous, Timed, ST, Vauto, and CPAP). In addition to ventilator synchronization, the VPAP ST supports ResMed's Easy-Breathe Technology, TiControl, Vsync, and new optional Humidaire H4i Heated Humidifier.

When non-invasive ventilation is required, ResMed offers three modes: Spontaneous, Spontaneous/Timed, and Timed. The VPAP ST and T modes provide a customizable backup rates to force a switch from exhalation to inhalation. Spontaneous mode simply reacts from the lack of breath with no time interval. Ventilated therapy can now take advantage of Easy Breathe technology.

VAuto is engineered to prevent obstructions before they occur by responding quickly and accurately to flow limitations. The algorithm works on a breath per breath basis and automatically adjusts to find the lowest required pressure needed to prevent most snoring and apnea events. VAuto is so consistent in response to events it often adjusts on the very next breath after a flow limitation or obstruction.

TiControl allows CPAP users to set minimum and maximum inspiratory time limits that provide a range to accommodate treatment for chronic obstructive pulmonary disease and respiratory conditions. ResMed has also included five trigger and cycle settings that help manage patient inhalation and exhalation patterns. Vsync is unique to the VPAP Series that automatically minimizes pressure loss due to mask leaks. All three technologies help regulate IPAP/EPAP intervals through monitoring the breathing cycle (BPM) and Rise time.

Enjoy the new Easy-Breathe technology which offers smoother, comfortable pressure by synchronizing with the CPAP user's normal breathing patterns, allowing for a natural and stable breath. Easy-Breathe Technology imitates normal respiration that makes breathing more comfortable than traditional CPAP or BiLevel machines. The transition from EPAP to IPAP pressures is gentle and slides into an exhalation curve that feels more natural. The final result is a VPAP machine that is intuitive, effective and produces only 26dB decibels at 10cmh20 at a distance of 1 meter.

Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE THE DC-24 Converter For ResMed 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 Humidiare humidifier is disabled when using the DC-24 Converter For S8 Machines. You will need the DC to AC Pure Sine Wave Power Inverter to operate both.

ResMed VPAP Auto 25 and VPAP ST

The ResMed VPAP Auto 25 and VPAP ST use a different cord, DC-24 Converter For ResMed. Refer to the Respironics Battery Kit for ResMed VPAP Auto 25, VPAP Malibu & VPAP ST Machines for a battery kit for these machines

Humidification

The optional heated humidifier will not operate with DC Power and will need a Pure Sine inverter. Do not run this machine on a regular DC to AC inverter. The DC to AC Pure Sine Wave Power Converter for Resmed S8 Machines must be used when using both the VPAP and humidifier.

The VAP Auto 25, VPAP ST and VPAP IV are not compatible with ResMed's Humidaire H3i Heated Humidifier. Please select the Humidaire H4i when purchasing a humidifier for this machine.

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.

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 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.

Battery Power for S8 VPAP ST

ResMed DC-24 Converter

The VPAP Auto 25 and VPAP ST come equipped with a DC plug on the back of the unit. This allows the user to connect the CPAP to an external DC battery source. These VPAP machines run on 24Volt DC Power and must use the ResMed DC-24 Converter when connected to a DC battery. This cord is ideal for travel by recreational vehicle, boat, or any external DC batter that is equipped with a cigarette lighter plug.

What is the difference BiPAP and BiPAP ST?
A BiPAP (also referred to as a BiLevel or VPAP) delivers two set pressures, a higher pressure for inhalation and a lower pressure for exhalation.

BiPAP and BiPAP ST machines are similar, as they are both designed to provide the same airway pressure. The difference between a BiPAP and a BiPAP ST is the Spontaneous Timed feature. The ST responds to the user when the minimum number of breaths per minute has not been met. This machine ensures all breaths occur by triggering the user to take another breath within the minute.

For example, a BiPAP might be set at the following:
  • Inhalation Pressure - 10
  • Exhalation Pressure - 5
In this case, a BiPAP will provide an IPAP of 10 and EPAP of 5.

A BiPAP ST might be set at the following:
  • Inhalation Pressure - 10
  • Exhalation Pressure - 5
  • 12 BPM (Breath Per Minute)
Similarly to the regular BiPAP, the BiPAP ST will provide an IPAP of 10 and EPAP of 5, and will additionally monitor if you inhale 12 times within the minute. Please Note: The ST will not breathe for you, rather it will prompt the user to take a breath.

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.

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.

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

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:

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.
