Oxlife LIBERTY2 Portable Oxygen Concentrator with Continuous & Pulse Flow

The Oxlife LIBERTY2 Portable Oxygen Concentrator combines continuous-flow oxygen up to 2.0 LPM with 10 pulse dose settings in one compact portable oxygen system.

Designed for prescribed oxygen users who need greater flexibility at home and away, the LIBERTY2 provides continuous and pulse dose oxygen delivery without the size of a traditional stationary concentrator. Continuous flow is adjustable from 0.5 to 2.0 LPM in 0.25 LPM increments, while pulse mode provides settings 1–10.

At approximately 6.35 lbs. and measuring just 9.9" H × 9.9" W × 3.8" D, the LIBERTY2 combines portable size with oxygen-delivery capabilities not commonly found in lightweight pulse-only portable oxygen concentrators.

Who Is the Oxlife LIBERTY2 For?

The LIBERTY2 is designed for individuals who have been prescribed supplemental oxygen and require an oxygen delivery mode and setting supported by the device.

It may be worth considering when:

• Continuous-flow oxygen is prescribed but greater portability is desired

• Pulse dose oxygen is prescribed and multiple pulse settings are needed

• Both continuous and pulse delivery modes are useful within the prescribed oxygen plan

• A smaller alternative to a full-size stationary concentrator is desired for appropriate prescribed use

• Battery, AC, and vehicle DC power options are important

• Air travel is part of the user's mobility needs

• A compatible continuous-flow POC is required as part of an appropriate CPAP setup

The correct oxygen mode and setting must be determined by the patient's healthcare provider.

Pulse dose settings are not equivalent to continuous-flow liters per minute. Do not change oxygen delivery modes or prescribed settings without instructions from the prescribing clinician.

Specifications

Continuous Flow + Pulse Dose in One Portable Concentrator

One of the LIBERTY2's most important features is its ability to provide both continuous-flow and pulse dose oxygen from a portable system.

Continuous flow is adjustable from 0.5 to 2.0 LPM in 0.25 LPM increments.

Pulse mode provides settings 1 through 10, with bolus sizes ranging from 8 to 80 mL.

This dual-mode design gives prescribed oxygen users an option worth comparing with portable concentrators that provide pulse dose oxygen only.

Important: Pulse settings such as 1, 2, or 3 do not mean the same thing as 1, 2, or 3 liters per minute of continuous oxygen. Use only the oxygen delivery mode and setting prescribed by your healthcare provider.

Continuous Flow Up to 2.0 LPM

For users prescribed continuous oxygen delivery within the LIBERTY2's operating capabilities, the device provides 0.5–2.0 LPM continuous flow.

The ability to provide continuous flow from a device weighing approximately 6.35 lbs. is one of the LIBERTY2's distinguishing features.

O2 Concepts describes the LIBERTY2 as its wearable portable oxygen concentrator capable of providing continuous flow up to 2.0 LPM.

Compact 6.35 lb. Portable Design

The LIBERTY2 measures approximately:

• 9.9" high

• 9.9" wide

• 3.8" deep

• 6.35 lbs. device weight

Its compact dimensions and multifunction carry bag are designed to make prescribed oxygen easier to incorporate into everyday activities away from a stationary home setup.

Rechargeable Battery Operation

The LIBERTY2 can operate from its rechargeable battery, allowing prescribed oxygen therapy to continue away from an AC or DC power source.

O2 Concepts specifies battery duration of up to 4.5 hours, but actual runtime varies significantly according to oxygen mode and setting.

Typical operating time with a new, fully charged battery may be approximately:

Battery operating times are estimates for a new, fully charged battery and can vary. Runtime decreases with battery age, charge cycles, oxygen setting, and operating environment.

AC & DC Power Options

In addition to battery operation, the LIBERTY2 supports both AC and DC external power.

The AC power supply supports compatible household electrical power, while the DC power cord provides additional flexibility when using an appropriate vehicle power source.

O2 Concepts specifies vehicle performance using DC power across the LIBERTY2's available settings.

Using external power when available can also help preserve available battery capacity for periods when AC or DC power is unavailable.

Battery Charging

The rechargeable battery can be charged while using the appropriate external power source.

Battery recharge time is specified at under 2.5 hours under applicable charging conditions.

Charging time and performance can vary when the concentrator is operating while the battery is being charged.

Color LCD Display

The LIBERTY2 includes a color LCD screen with keypad controls.

The interface provides access to oxygen settings and device operating information without requiring complicated controls.

Energy Smart Technology®

The Oxlife LIBERTY2 incorporates O2 Concepts' Energy Smart Technology®, designed to help efficiently manage device power while supporting its portable oxygen capabilities.

This technology is particularly relevant in a portable system that may alternate among battery, AC, and DC power throughout the day.

DNA Technology® Connectivity

The LIBERTY2 also incorporates O2 Concepts' DNA Technology® Device Connectivity Platform.

DNA Technology supports connected equipment management and provides equipment providers with device performance and usage information.

This feature is primarily designed to support equipment management and monitoring rather than replace the patient's prescribed oxygen instructions or routine medical care.

CPAP Compatibility

One unusual capability of the LIBERTY2 is its continuous-flow functionality for compatible CPAP setups.

O2 Concepts currently identifies the LIBERTY2 as a wearable continuous-flow portable oxygen concentrator allowing CPAP compatibility.

Actual CPAP and oxygen equipment compatibility should always be confirmed before use. The prescribed oxygen setup should follow the instructions of the patient's healthcare provider and the manufacturers of the equipment involved.

Air Travel With the LIBERTY2

The LIBERTY2 is designed for portable use and is identified as meeting applicable FAA requirements for air travel.

Before flying:

• Contact the airline before travel

• Confirm the airline's current portable oxygen concentrator requirements

• Determine how much battery capacity the airline requires for the planned trip

• Carry required documentation or prescription information when applicable

• Plan for flight time plus potential delays

Airline policies and battery requirements can vary, so approval and travel arrangements should always be confirmed directly with the airline before departure.
