Who Is the Rhythm Healthcare P2-E6 For?

The P2-E6 is designed for individuals who have been prescribed pulse dose oxygen therapy at a setting supported by the device.

It may be worth considering when:

• Pulse dose oxygen has been prescribed

• A lightweight alternative to a stationary oxygen concentrator is needed for appropriate portable use

• Six pulse settings provide the range required by the patient's prescription

• Rechargeable battery operation is important for time away from an electrical outlet

• AC and vehicle DC power options are useful

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

• A portable concentrator designed for continuous-duty operation is desired

The appropriate oxygen setting must be determined by the patient's healthcare provider.

The P2-E6 is a pulse dose concentrator. Pulse settings 1–6 are not equivalent to continuous-flow liters per minute.

Specifications

*Current warranty terms apply to qualifying units purchased on or after January 1, 2026. Earlier purchases remain subject to the warranty terms applicable at the time of purchase.

Lightweight Portable Oxygen at 4.37 lbs.

The P2-E6 weighs approximately 4.37 lbs. with its battery installed and measures about 8.7" × 3.4" × 6.3".

Its compact footprint is designed to make prescribed oxygen easier to incorporate into everyday mobility than a full-size stationary concentrator.

Because the battery is included in the published weight, customers get a more useful picture of the device's actual carrying weight during normal portable use.

Six Pulse Dose Settings

The P2-E6 provides six adjustable pulse settings from 1 through 6.

Unlike a continuous-flow oxygen concentrator, which continuously releases oxygen at a prescribed liters-per-minute flow rate, the P2-E6 uses breath-triggered pulse delivery.

When the concentrator detects the beginning of an inhalation, it delivers a measured oxygen pulse.

Pulse volume changes according to both the selected setting and the user's breathing rate.

Important: Pulse settings are not equivalent to continuous-flow LPM. For example, Setting 2 should not automatically be interpreted as 2 LPM continuous flow.

Use only the setting prescribed by the patient's healthcare provider.

Pulse Delivery & Oxygen Output

Rhythm Healthcare specifies a maximum oxygen output of 1,200 mL/min for the P2-E6.

The amount delivered with each breath varies according to the selected setting and breathing rate.

As breathing rate changes, the device adjusts individual pulse volume while operating within its specified oxygen-delivery parameters.

This is one reason portable oxygen concentrators should be evaluated according to their actual delivery method and the patient's prescription rather than comparing pulse setting numbers directly with continuous-flow LPM.

Built-In Oxygen Monitoring & Alarms

The P2-E6 incorporates oxygen concentration monitoring and multiple operating alarms designed to alert the user when the concentrator requires attention.

Monitored conditions include:

• Low oxygen concentration

• Incorrect oxygen concentration

• Oxygen concentration sensor error

• Power failure

• High or low temperature

• Low battery

• High or low pressure

• Sieve bed condition

These monitoring systems help patients and caregivers identify operating conditions that may require troubleshooting, service, or another appropriate response according to the manufacturer's instructions.

Battery Duration by Setting

Battery runtime varies considerably according to the selected pulse setting.

With a new, fully charged battery under specified conditions, Rhythm Healthcare publishes the following approximate operating times:

These figures are estimates rather than guaranteed real-world runtime.

Actual battery duration can vary according to battery age and condition, charge level, oxygen setting, breathing pattern, environmental conditions, and device use.

For customers who spend extended periods away from external power, battery planning should be based on the prescribed setting, not simply the maximum advertised runtime.

Rechargeable Battery & Charging

The P2-E6 uses a rechargeable 14.4V lithium-ion battery rated at approximately 6.7Ah / 6700mAh.

Rhythm Healthcare specifies a battery charging time of up to approximately four hours with the appropriate AC power source.

Additional compatible batteries and charging accessories are available separately for customers who require greater time away from an external power source.

AC & DC Power Options

The P2-E6 supports both AC and DC power, giving users multiple options for powering the concentrator and supporting battery charging.

The AC power supply accepts 100–240V, 50–60Hz, providing auto-sensing capability for compatible electrical sources.

Compatible DC power also allows the concentrator to be used with an appropriate vehicle power source.

Always use the manufacturer-approved power equipment intended for the P2-E6.

2.8" Color LCD Display

A built-in 2.8-inch color LCD provides access to oxygen settings and important device information.

Straightforward controls and the easy-to-read display are designed to make routine device operation easier while helping users monitor the concentrator's status.

Designed for 24/7 Use

Rhythm Healthcare identifies the P2-E6 as designed for 24/7 use, and the manufacturer manual classifies the device for continuous-duty operation.

That does not mean the rechargeable battery will operate for 24 hours without charging.

For extended operation, users must plan appropriate access to AC power, DC power, charged batteries, or other prescribed backup oxygen arrangements.

Operating Environment

Rhythm Healthcare specifies the P2-E6 for operation within the following environmental range:

• Temperature: 41°F–104°F (5°C–40°C)

• Humidity: 10%–90%, non-condensing

• Altitude: Up to 10,000 ft. (3,048 m)

Operating outside the manufacturer's specified environmental range may affect equipment performance.

Air Travel With the P2-E6

Rhythm Healthcare states that the P2-E6 conforms to applicable FAA criteria for portable oxygen concentrator carriage and use aboard aircraft.

Before traveling by air:

• Contact the airline before departure

• Confirm its current portable oxygen concentrator procedures

• Ask about required documentation

• Determine the required battery capacity for the planned itinerary

• Account for flight time, airport time, connections, and possible delays

• Carry adequate charged battery capacity according to airline requirements

FAA criteria do not eliminate individual airline procedures, so travel arrangements should always be confirmed directly with the carrier.
