The VPAP Auto 25 uses VAuto technology to adjust automatically using ResMed's unique AutoSet algorithm. 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.
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.
Additional features include the TiControl, Vsync and five sensitivity settings that provide additional fine-tuning to the VPAP Auto 25. 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.
The machine is suited with three mode options, VAuto, Spontaneous, and CPAP, proving to be one of the most flexible flow generators in the market, delivering all of the comfort available for successful compliance and treatment.

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 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.

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
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 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 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!

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.

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.
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.
