LiveO2 Dual User Extreme Adaptive Contrast EWOT System

System Type

LiveO2 Dual User Extreme adjustable Adaptive Contrast Exercise with Oxygen Therapy (EWOT) system with two training stations. Designed for clinics, recovery centers, athletic facilities, wellness studios, performance environments, and dedicated multi-user home settings where flexible single- or dual-user operation is desired.

Oxygen Training Method

Adaptive Contrast oxygen training with alternating oxygen-rich and simulated-altitude breathing phases. Adjustable simulated altitude ranges from approximately 10,000 to 22,000 feet.

Each training station has its own breathing switch, while both users share the same selected simulated-altitude setting.

User Capacity

Supports one or two users at the same time.

When one person trains, that user can access the system’s available air supply. When two people train simultaneously, the available air supply is shared between them.

User Throughput

LiveO2 does not specify a fixed number of users per hour for the Dual User Extreme.

Actual throughput depends on session duration, selected altitude, whether one or two people are training, individual air demand, reservoir status, and the time required for cleaning and changeover between sessions.

Higher air-supply capacity provides additional available supply but does not guarantee a specific number of clients per hour.

Air Separator Configuration

20 LPM standard configuration: 2 × 10 LPM air separators

30 LPM configuration: 3 × 10 LPM air separators

40 LPM configuration: 4 × 10 LPM air separators

LPM describes rated oxygen production rather than reservoir size or the amount of air delivered with each breath.

Reservoir Operation

The oxygen chamber continues refilling while the system is operating, including during use.

LiveO2’s current product specifications do not provide fixed reservoir fill-time estimates for the 20 LPM, 30 LPM, or 40 LPM configurations. Initial reservoir filling is different from preparing an already-filled, operating system for subsequent users.

Reservoir Dimensions

Reservoir: approximately 96 in H × 57 in W when laid flat

Filled depth: approximately 36 in

These measurements describe the reservoir itself and do not include the freestanding frame.

Frame Dimensions

Freestanding frame configuration: approximately 8 ft 6 in H × 6 ft W × 3 ft D

The support frame and stabilizing legs extend beyond the reservoir itself.

Air Separator Dimensions

Each air separator: approximately 23.6 in H × 15 in W × 14.6 in D

Allow at least 8 in of open space on all sides of each air separator for ventilation.

Placement Requirements

For wall or ceiling mounting, hanging points should be spaced approximately 4 ft 6 in apart, with at least 8 in between the reservoir and the wall so the reservoir can fill freely.

Allow additional room for the selected number of air separators, tubing, two training stations, exercise equipment, and safe movement around the system.

The freestanding frame requires approximately 8 ft 6 in of vertical clearance and approximately 6 ft × 3 ft of floor area before accounting for exercise equipment and user movement.

Altitude / Hypoxic Challenge

Adjustable simulated altitude: approximately 10,000–22,000 ft

Both training stations share the same altitude setting. The system cannot operate one user at one simulated altitude and the second user at a different altitude simultaneously.

Each user can independently switch between oxygen-rich and simulated-altitude air.

Mask System

Includes 2 Premium EWOT Mask Kits and 10 Standard Neoprene Mask Kits.

Airflow / Outflow Design

LiveO2 uses a Neutral Pressure™ breathing system rather than positive-pressure breathing assistance.

Two independent breathing switches allow each user to move between oxygen-rich and simulated-altitude air during Adaptive Contrast sessions.

Power Requirements

U.S.: 110V / 60 Hz

International: 110V / 60 Hz or 220V / 50 Hz configurations are available depending on destination.

Reservoir Materials & Low-VOC Liner Design

LiveO2 reservoir construction is designed with the breathing pathway in mind. The reservoir uses a thin oxygen-retaining liner to reduce unnecessary plastic exposure, along with a woven nylon protective shell for durability and a low-VOC inner liner. LiveO2 reservoir materials are tested clean below 3 parts per million, and the system uses biologically inert silicone tubing rather than PVC in the breathing pathway.

Inspection-Friendly, Non-Pressurized Reservoir Design

LiveO2 reservoirs use a white exterior to support easier visual inspection and include a zipper with an inspection/drainage port for internal inspection, rapid drainage, and care access when needed. The reservoir is designed to avoid sealed pressurization, allowing excess gas to escape rather than trapping gases inside the air compartment.

The LiveO2 Dual User Extreme is available in 20 LPM, 30 LPM, and 40 LPM air-supply configurations. The standard 20 LPM system uses two 10 LPM air separators, the 30 LPM configuration uses three, and the 40 LPM configuration uses four.

The 20 LPM configuration supports both solo and paired training, while the 30 LPM and 40 LPM options provide additional available air supply for more demanding paired sessions and higher-use clinic or performance environments. Actual user throughput depends on session length, simulated altitude, individual air demand, whether one or two people are training, and cleaning and changeover time between sessions. Higher flow increases available supply but does not guarantee a fixed number of users per hour.

The reservoir can be installed using a wall or ceiling mounting arrangement or with the optional freestanding frame configuration. For the frame setup, plan for approximately 8 ft 6 in H × 6 ft W × 3 ft D, in addition to the space required for exercise equipment and safe movement around both training stations.

The LiveO2 Dual User Extreme can be installed in professional indoor environments such as clinics, recovery centers, athletic facilities, wellness studios, and performance training spaces. It may also be appropriate for dedicated home gyms or wellness rooms where multiple household members, athletes, or training partners plan to use the system regularly.

The reservoir measures approximately 96 in H × 57 in W when laid flat and approximately 36 in D when filled. For wall or ceiling mounting, hanging points should be spaced approximately 4 ft 6 in apart, with at least 8 in between the reservoir and the wall so it can fill freely.

For the freestanding frame configuration, plan for approximately 8 ft 6 in H × 6 ft W × 3 ft D. These dimensions do not include the additional space required for exercise equipment, tubing, user access, or movement around the training area.

Each air separator measures approximately 23.6 in H × 15 in W × 14.6 in D and should be placed on the floor with at least 8 in of open space on all sides for ventilation. The 20 LPM configuration uses two air separators, the 30 LPM configuration uses three, and the 40 LPM configuration uses four.

For paired sessions, allow adequate room for two bikes or other compatible exercise stations, both breathing stations, tubing pathways, and safe movement throughout the training area. Households with more than two regular users can share the system across separate or paired sessions, with a maximum of two users training simultaneously.

LiveO2 provides a limited manufacturer warranty for the original purchaser covering qualifying defects in materials or workmanship.

Standard Manufacturer Warranty: 2 years

Optional Extended Warranty: 4 years

Masks, pulse oximeters, breather hoses, shipping responsibilities, exclusions, and claim procedures are subject to LiveO2’s current manufacturer warranty terms and may be handled differently from primary system components.

Customers should review LiveO2’s current warranty terms for the applicable usage-hour limits, covered components, exclusions, shipping responsibilities, and claim requirements at the time of purchase.

What is the LiveO2 Dual User Extreme Adaptive Contrast EWOT System?

The LiveO2 Dual User Extreme Adaptive Contrast EWOT System is a two-station Exercise with Oxygen Therapy (EWOT) system designed primarily for clinics, recovery centers, athletic facilities, wellness studios, and performance environments. It combines oxygen-rich breathing, simulated-altitude breathing, and adjustable altitude control from approximately 10,000 to 22,000 feet within one Adaptive Contrast system.

Is the LiveO2 Dual User Extreme Adaptive Contrast EWOT System an IHHT system?

The LiveO2 Dual User Extreme is an active Exercise with Oxygen Therapy (EWOT) and Adaptive Contrast system that alternates between oxygen-rich and simulated-altitude breathing phases. This creates similarities to intermittent hypoxic-hyperoxic training (IHHT) and hypoxic hyperoxic training, but LiveO2 is designed around active exercise rather than functioning as a conventional passive IHHT machine or IHHT device.

How is the Dual User Extreme different from the single-user LiveO2 Extreme?

Both systems provide Adaptive Contrast training with adjustable simulated altitude from approximately 10,000 to 22,000 feet. The LiveO2 Extreme has one training station and is available in 10 LPM or 20 LPM configurations. The Dual User Extreme has two training stations, starts with a 20 LPM configuration, and is also available with 30 LPM or 40 LPM air-supply configurations for paired and higher-demand professional use.

Can two people use the LiveO2 Dual User Extreme at the same time?

Yes. The Dual User Extreme has two valves, two Adaptive Contrast switches, and two breathing hoses so two people can train simultaneously. Both users share the system’s available air supply and operate at the same selected simulated-altitude setting, while each person independently controls whether they are breathing oxygen-rich or simulated-altitude air.

What is the LiveO2 Air Separator, and is it the same as an oxygen concentrator?

The LiveO2 Air Separator produces the oxygen-rich and oxygen-reduced air used by the Adaptive Contrast system. LiveO2 uses the term Air Separator because the component supplies both sides of the contrast-training process rather than functioning as a conventional medical oxygen concentrator.

Is the LiveO2 Dual User Extreme an EWOT system or an Adaptive Contrast system?

It is both. The Dual User Extreme is an Exercise with Oxygen Therapy (EWOT) system that also incorporates LiveO2 Adaptive Contrast, allowing users to alternate between oxygen-rich and simulated-altitude breathing during structured exercise sessions.

What does adjustable Adaptive Contrast mean on the Dual User Extreme?

Adjustable Adaptive Contrast means the simulated-altitude side of the system can be set from approximately 10,000 to 22,000 feet. This allows altitude challenge to be adjusted according to the selected training protocol rather than remaining at one fixed simulated altitude. Both training stations share the same altitude setting.

What is the difference between the 20 LPM, 30 LPM, and 40 LPM configurations?

The difference is the system’s rated oxygen-production capacity and the number of air separators included. The standard 20 LPM configuration uses two 10 LPM air separators, the 30 LPM configuration uses three, and the 40 LPM configuration uses four.

Higher-output configurations provide additional available air supply for paired or more demanding use. They do not guarantee a specific number of users per hour, since actual demand depends on session length, selected altitude, whether one or two people are training, and individual breathing requirements.

What makes the Dual User Extreme useful for clinics, recovery centers, and performance facilities?

The Dual User Extreme combines two training stations, adjustable simulated altitude, and configurable 20 LPM, 30 LPM, or 40 LPM air supply within one system. Facilities can use it for paired sessions or a single client depending on scheduling needs, helping reduce equipment duplication while providing flexibility across different training sessions.

Can the LiveO2 Dual User Extreme also be used in a home setting?

Yes. The LiveO2 Dual User Extreme can be a practical home option for households with multiple regular users, including families with several athletes, training partners, or wellness-focused household members. The system supports up to two people training simultaneously and can also be shared across separate sessions by additional household members.

A dedicated home gym or wellness space should provide adequate room for the reservoir, air separators, exercise equipment, tubing, and safe movement around the training area.

For a single person who will be the system’s primary user, LiveO2 recommends the single-user Extreme. For households where several people expect to use the system regularly, however, the Dual User Extreme offers greater shared-use flexibility.

Does the LiveO2 Dual User Extreme include coaching and training support?

Yes. The Dual User Extreme includes owner access to the LiveO2 Training App and one New User Coaching package with a qualifying system order. The Training App provides guided sessions, session timers, training history, progress tracking, and access to available training resources.

LiveO2 also provides phone or video assistance, setup guidance, an instruction manual, support-portal access, and access to its private user community. Staff certification and certain additional training resources are separate from the included New User Coaching package.

The LiveO2 Dual User Extreme is installed by positioning the adjustable-altitude dual-user reservoir using the selected wall, ceiling, or freestanding frame configuration, connecting the 20 LPM, 30 LPM, or 40 LPM air-separator setup, attaching the required silicone tubing and connectors, and preparing both breathing stations for use.

The system should be installed indoors with adequate room for the reservoir, air separators, tubing pathways, two breathing stations, exercise equipment, and safe movement around the training area. When two people train simultaneously, both users share the system’s available air supply and operate at the same selected simulated-altitude setting, while each user independently controls switching between oxygen-rich and simulated-altitude air.

Before beginning structured sessions, owners should review the LiveO2 instruction manual and setup guidance and complete the included New User Coaching and available Training App resources. LiveO2 recommends becoming familiar with reservoir setup, breathing controls, pulse oximeter use, session structure, and appropriate altitude progression before beginning more advanced training.

Because the Dual User Extreme provides adjustable simulated altitude from approximately 10,000 to 22,000 feet, users should follow LiveO2’s current manufacturer guidance for setup, monitoring, user pairing, and training progression.

The LiveO2 Dual User Extreme should be maintained according to LiveO2’s current cleaning, inspection, and maintenance guidance. Masks should be cleaned after each use, and each user should ideally have a dedicated mask or inner mask body in multi-user environments. Breather hoses should be cleaned approximately monthly or whenever contamination is suspected and allowed to dry completely before reuse.

Keep all air separator ventilation areas unobstructed and maintain the required clearance around each unit. LiveO2 also specifies routine air-separator filter maintenance, including weekly cleaning of the external gross-particle filter and periodic inspection or servicing of internal intake filters based on accumulated operating hours.

After each session, disconnect the mask from the breathing hose, clean and dry the mask before storage, and loosely coil the breathing hose to help prevent kinking. Masks, hoses, and other user-contact components should be stored in a clean, dry indoor location.

For clinics, athletic facilities, wellness studios, recovery centers, and other shared-use environments, mask hygiene and cleaning procedures should be managed carefully between users. LiveO2 recommends following its current cleaning and decontamination instructions for masks, breathing hoses, filters, and other system components rather than using fragranced soaps, essential oils, or harsh chemical cleaners that may damage materials.

Do not attempt internal service of the air separators. Internal repairs or service beyond routine owner maintenance should be handled according to LiveO2’s current technical-support guidance.

LiveO2 was founded by electrical engineer Mark Squibb after health challenges affecting his family led him to investigate oxygen delivery and the limitations of conventional oxygen approaches. What began as an engineer-led effort to solve a practical problem eventually developed into an oxygen training company built around Adaptive Contrast, a method that alternates oxygen-rich and simulated-altitude breathing phases during structured exercise. LiveO2 presents its development as a process shaped by engineering, real-world testing, user experience, and continued refinement of its oxygen training systems.

Today, LiveO2 manufactures specialized oxygen training systems for home users, athletes, wellness-focused individuals, and professional environments such as clinics, studios, gyms, and performance facilities. The company supports its systems with the LiveO2 Training App, New User Coaching, setup guidance, instructional resources, protocol training, technical support, and customer care.

For SanaVi Health Systems, LiveO2 represents an important part of the Exercise with Oxygen Therapy category because its Adaptive Contrast technology expands beyond oxygen-only EWOT by incorporating alternating oxygen-rich and simulated-altitude breathing within structured exercise sessions.
