The backlight for this machine either shuts off automatically after a short intreval or can be set to off.
The machine display is lit for ease of reading.
These machines were designed with a woman's lifestyle in mind.
Timed (T) or Spontaneous Timed (ST) modes provide a customizable backup rate that forces the machine to switch from exhalation to inhalation. In ST Mode, the machine monitors the breathing cycle and switches from EPAP to IPAP once the backup time is met or whenever the break is detected through the sensors; whichever occurs first. The time aspect is only meant to act as a backup respiratory rate to the (S) function (see Spontaneous). This is used for patients with central sleep apnea, or those who need non-invasive mechanical ventilation.
Spontaneous (S) mode tells the machine to start blowing at IPAP pressure with no specific interval set. The machine must wait and detect a break in the breathing cycle before reacting, switching from exhalation to inhalation. If a backup rate is needed, then the unit will need a time interval setting and will be marked 'Yes' on the Timed property.
This feature detects excessive mask leaks due to poor cushion seal or when a user stops therapy by removing a mask when in use. The alert can be in the form of an audible alarm (ALARM) or a text message on the unit's LCD display (LCD).
This feature turns the machines off and on when putting on or taking off the mask. When you put your mask on the machines senses you breathing and turns itself on. Take off the mask and the machine turns off.
Altitude Adjustment is defined as the machine's ability to compensate for changes in altitude. Compensation can either occur manually or automatically. Manual adjustments occur within the Setup Menu and must be set by the user. Automatic requires no user intervention.
Software is an option on some CPAP machines. The software can give details on compliance and performance. The patient or physician downloads the data from the CPAP machine to determine how long a patient has used their machine each night and how well the machine is working to stop Apnea/Hypopnea events. This property shows the software package to use for machine that has the ability to transfer data to your computer and report Hours of Usage. See Advanced Software for a list of machines that can report AHI or Leakage.
This property marks the machines that have the ability to record performance data on a removable card. Some machines that are flagged as having software (seeOptional Software), do not have removable memory cards, rather instead, records information on-board and must use a download cable to retrieve the data from the machine.
Identifies which machines are data capable and have the ability to track your therapy progress over time. The machine captures key metrics like AHI (Apnea/Hypopnea Index), Leakage, and most pressure used. Depending on the machine, the data can be retrieved through an on Machine Screen Display (MSD), through Optional Software (OS), and/or through SmartCode (SC).
An integrated battery pack attaches to and functions seamlessly with the machine it is integrated with. It allows your CPAP to run on AC and fail over to the DC battery only if necessary.
A 'Yes' answer indicates that the CPAP Machine has an optional DC cable that plugs directly into a DC port. This allows you to use a DC power source, such as a battery or car cigarette lighter outlet. Some optional DC cables include alligator clips to connect directly to battery terminals. See the "Power" tab of the machine's product page for more detailed information on how the machine works with alternate power sources, and what optional cables and batteries are compatible.
Domestic Voltage is the voltage that is used with a standard wall outlet in the United States and ranges from 100-120 volts. International Voltage can range from 220v-240v AC.
Indicates which machines have a DC port in which you can use to connect a battery pack or a deep cycle marine battery with an optional DC cable. This is different from an integrated battery that works only with the machine it was designed for. (i.e. Everest CPAP Machine) see property Integrated Battery
This is the maximum altitude at which the machine will properly operate.
Leak Compensation is a machine feature that identifies mask leaks and adjusts to maintain the delivered pressure as set. If marked N/A assume the information is not available due to being out of production or unavailable.
This property defines whether the machine is capable of continuously blowing a constant pressure. All CPAP machines are defined as 'continuous', but some BiPAP's and APAP's also come with a CPAP mode; some BiPAP and BiLevel machines Do NOT. By setting the IPAP and EPAP to the same pressure, a CPAP Mode is achieved, preventing the EPAP pressure from dropping.
The Ramp feature allows the user to start treatment at a lower pressure to fall asleep with, gradually raising the pressure over a set time. This is a comfort setting and can set from 0 to 45 minutes on most CPAP machines.
Pressure Relief is a feature that lowers your therapy pressure to help with difficulties breathing against the machine's airflow, providing a more comfortable and natural breathing pattern. Assistance can occur on the Exhalation, on the Inhalation, and on both exhalation and inhalation at the same time.
This Property lists the operating range for the Exhalation Positive Airway Pressure (EPAP). This is the pressure setting used when you exhale. EPAP is always lower than the IPAP (inhalation) pressure, making breathing out easier and more comfortable.
A CPAP (Constant Positive Air Pressure) delivers continuous airflow at a prescribed pressure at 4cm to 30cm. APAP operates between a range and BiPAP machines are a mix of ranges and constant pressures. This pressure is measured in centimeters of water pressure (H2O) and 4-20cm is average pressure range on most CPAP machines.
This property defines whether the machine automatically adjusts pressure to meet the needs of the CPAP user on a breath-by-breath basis. All APAP machines are defined as 'Auto Adjusting', but some BiPAP's also use an Auto feature on both the IPAP and EPAP. If not marked, Yes, assume the machine does not have AUTO capabilities.
This is the maximum water capacity held by the chamber of the compatible humidifier.
This indicates that the machine has an integrated heated hose option to enhance humidification and reduce rainout. An integrated headed hose receives power directly from the machine and does not require a power supply. The tube's heat settings are set through the machine menu screen.
A yes in this field indicates the machine and humidifier have technology to reduce rainout, the water that collects in a hose when using a heated humidifier. Sensors measure the air temperature in the room and adjust the amount of heat and moisture delivered to the mask to reduce or omit rainout.
This property identifies how the machine incorporates a Heated Humidifier. Build In humidifiers are built into the CPAP machine and cannot be separated from the machine. Integrated humidifiers connect directly to the CPAP machine and they can only be used with compatible CPAP machines. With Integrated humidifiers, the CPAP machine, can be separated and used without the humidifier. CPAP machines that do not have a built in humidifier and do not have an integrated humidifier option have to use a Stand Alone humidifier as the machine's heated humidifier option. Stand Alone humidifiers can be used with any machine and connect to the CPAP machine with an additional hose.
Identifies which CPAP has a humidifier that is built into the CPAP. Built-In humidifiers cannot be separated from the CPAP machine.
This indicates which heated humidifier works best with the listed CPAP machine. In some instances, Built-in is used to describe a machine/humidifier combination system. The Fisher and Paykel HC150 was used for machines that do not have an integrated or built in humidifier system.
Measures the overall dimension of the machine only. Machines with a built-in humidifier are marked NA and must refer to Entire Size dimensions.
This is the size of the CPAP with Heated Humidifier in its travel bag.
This is the combined dimensions of the CPAP with the Heated humidifier.
This is the combined weight of the machine, heated humidifier, power cables, bag and hose. The weight of the shipping box is not included in the number.
This is the actual weight of the CPAP Machine without any accessories, power cord, or humidifier. Machines with a weight 3lbs or less are also identified in the Under 3 lbs property.
This measures only the weight of the machine and does not include total weight of power cables, bag, additional batteries or non-built-in humidifiers.
Looking to travel? We have found some machines are easier to travel with than others. These smaller and more lightweight machines are still robust enough for constant daily use as well as travel.
This indicates which manuals are included with the purchase of a CPAP machine. Most all machines come with a patient manual; also called 'user manual', which may or may not have pressure setting instructions. Some machines come with both the patient and quick setup guide or both patient and clinician manuals.
This identifies which machines have a decibel rating of 29 and lower. This does not account for use with the humidifier attached, which could supply additional volume that can muffle or amplify sound. This property does not account for noise that travels through the CPAP tubing, seemingly sounding louder than the measured db rating.
This is the level of sound the machine produces at a pressure of 10cm, standing 1 meter away or roughly 3 feet from machine. Measured in Decibels, the values also indicate whether the machine is considered a "quiet CPAP"; see Quiet property.
Warranty is the length of time that the manufacturer will guarantee a product to be free of defects. Warranties vary in length depending on manufacturer, but generally all machines come with a 2 Year Warranty.
This identifies the machine as continuous, auto adjusting, or bilevel operation. This does not identify whether the machine automatically adjusts pressure. Auto adjusting refers to APAP, whereas BiPAP Auto is differentiated using the Auto Pressure Adjustment property. BiPAP machines are defined further using Spontaneous or Timed properties.
A CPAP machine blows one constant pressure of air into your passageway throughout the night. Your ideal pressure was determined during your sleep study.
A BiPAP machine delivers two separate pressures of air; One when the patient inhales and a separate pressure when they exhale. The machine alternates between the two set pressures to help optimize your sleep apnea treatment.
An APAP machine automatically adjusts on a breath by breath basis to blow the minimum pressure needed to keep your airway open during sleep. This allows your machine to provide you with your ideal pressure nightly.
This is the company that produces the product being compared.
Complex Sleep Apnea can occur when a person's breathing does not improve despite exposure to CPAP therapy. The ResMed VPAP Adapt SV(Adaptive Servo Ventilation) delivers optimal therapy for complicated sleep-disordered breathing cases like Central Sleep Apnea and Cheyne-Stokes respiration.
The VPAP Adapt SV provides therapy that augments breathing during apnic periods and rapidly removes support when spontaneous breathing resumes. All this helps stabilize breathing and normalize oxygen levels.
Adaptive Servo Ventilation (Adapt SV) Algorithm
The VPAP Adapt SV uses an algorithm to assure that each breath is properly ventilated. The algorithm monitors three key factors to ensure synchronization between CPAP pressure support and the patient's breathing.
The patients own recent average respiration rate
Changes in patient airflow
Backup respiratory rate
The Servo Ventilation algorithm continuously measures these factors and calculates a target ventilation. The target is 90% of the current average breath per minute. Once irregular breathing occurs, the machine rapidly increases pressure in response to hypo-ventilation, then pressure support decreases when normal breathing resumes. The algorithm helps generate a smooth pressure waveform, which is similar to normal breathing, ensuring that the rapid response to an apnea doesn't wake the user.
Complex Sleep Apnea Detection and Response
The VPAP Adapt SV is designed to identify and respond to symptoms beyond classic OSA parameters. Detection is expanded to include data on Periodic Breathing and Respiratory Effort-Related Arousals (RERAs). This device can monitor the breathing cycle and deliver comfortable pressures proactively for patients with complex events such as:
Restrictive disorders (kyphosis or fibrosis)
Periodic breathing such as Cheyne-Stokes Respiration (CSR)
Obstructed airway apnea
Obesity with hypo-ventilation
Complex SDB
COPD and OSA
Neuro-muscular disorders and SDB
RERAs differ from a hypopnea or snoring event in that a RERA shows increased respiratory effort with each breath, culminating in a shift in brain wave activity and not necessarily a result of obstruction. Periodic breathing conditions such as Cheyne-Stokes respiration (CSR) and Central Apneas are advanced forms of Central Apnea and are identifiably different from Obstructed Apnea or snoring events.
Advanced Back-Up Rate
Complex Sleep Apnea is a form of Central Apnea that occurs as a result of CPAP therapy. In treating such users, care must be taken not to over or under-ventilate while still allowing for natural pauses in breathing. The advanced backup rate for the VPAP Adapt SV accounts for the user's spontaneous breathing. This system will automatically calculate the backup rate based on a natural respiratory rate.
