Who Is the Rhythm Healthcare LM5BA For?

The LM5BA is designed for individuals who have been prescribed stationary continuous-flow oxygen therapy within its 1–5 LPM operating range.

It may be considered when:

• A prescription requires continuous-flow oxygen within the 1–5 LPM range

• Replacing an existing 5-liter stationary oxygen concentrator

• A stationary home oxygen system is required

• Built-in oxygen purity monitoring and operating alarms are desired equipment features

• A compatible oxygen setup involving a transfill system is needed

The appropriate oxygen flow rate is determined by the patient's healthcare provider. Do not change a prescribed oxygen flow rate without instructions from the prescribing clinician.

5L vs. 10L Oxygen Concentrators

One of the most important considerations when comparing stationary oxygen concentrators is the patient's prescribed flow requirement.

The Rhythm Healthcare LM5BA provides continuous flow from 1–5 LPM. A 10L stationary concentrator provides a higher maximum flow capacity for prescriptions requiring oxygen delivery beyond the range of a 5L unit.

A 10L concentrator is not automatically a better choice simply because it provides greater maximum flow. The appropriate concentrator should match the patient's prescription and required equipment specifications.

If you're unsure which equipment matches an existing prescription, State Medical Equipment can help compare product specifications before ordering.

Specifications

Continuous-Flow Oxygen from 1–5 LPM

The Rhythm Healthcare LM5BA provides adjustable continuous-flow oxygen from 1 to 5 LPM with a manufacturer-specified oxygen concentration of 93% ± 3% throughout the rated flow range.

This makes the LM5BA a stationary home oxygen option for patients whose prescribed requirements fall within its operating range.

Oxygen flow should always be set according to the patient's prescription.

Built-In Oxygen Purity Monitoring

The LM5BA includes a standard oxygen purity sensor to monitor the concentration of oxygen produced by the concentrator.

The unit includes a low-oxygen warning system. When oxygen concentration falls below the specified threshold of 82%, the red service indicator activates.

The LM5BA also incorporates alarms for operating conditions including temperature, oxygen purity, high and low pressure, power failure, and blockage.

These monitoring features help patients and caregivers identify when the concentrator requires attention.

Quiet, Compact Stationary Design

The LM5BA measures approximately:

• 23" high

• 14.2" wide

• 11.4" deep

• 35.25 lbs.

Its sound pressure level is rated at less than 50 dBA, helping reduce operating noise during everyday home use.

Although the LM5BA can be repositioned when necessary, it is a stationary oxygen concentrator and should not be confused with a portable oxygen concentrator.

Filtration & Maintenance

The LM5BA uses multiple filtration components as part of its oxygen concentrator system, including:

• Intake sponge filter

• HEPA air inlet filter

• Bacterial filter

Rhythm Healthcare offers replacement filtration components specifically for the LM5BA.

Routine care and filter maintenance should be performed according to the manufacturer's instructions to support proper concentrator operation.

Transfill Capability

Current LM5BA units feature a standard transfill port, expanding the concentrator's compatibility with appropriate oxygen cylinder transfill setups.

Rhythm Healthcare also offers the LM5BA9 Transfill Rack as a separate accessory.

The transfill rack is sold separately and should not be assumed to be included with the standard concentrator.

Confirm all required components and compatibility before purchasing or using transfill equipment.

Compatible Accessories & Replacement Supplies

Rhythm Healthcare offers several accessories and replacement components specifically for the LM5BA, including:

• Humidifier bottle

• Humidifier adapter

• Nasal cannula

• HEPA air inlet filter

• Bacteria filter

• Intake sponge filter

• LM5BA9 Transfill Rack

Accessories and replacement supplies are sold separately unless specifically stated as included with the concentrator being purchased.

Not sure which filter, humidifier component, cannula, or transfill accessory you need? Contact State Medical Equipment before ordering so we can help confirm the appropriate product.

5-Year Warranty & Rhythm Resolve

For new LM5BA purchases on or after January 1, 2026, Rhythm Healthcare currently provides a 5-year manufacturer warranty, subject to the manufacturer's applicable terms and conditions.

Earlier LM5BA purchases remain subject to the warranty terms that applied when the equipment was originally purchased.

The LM5BA is also covered under the Rhythm Resolve Warranty Replacement Program. For qualifying manufacturer defects, Rhythm Resolve is structured around replacement of eligible units rather than a traditional repair process, subject to Rhythm Healthcare's current program requirements and warranty terms.

Warranty claims are handled through the provider from which the equipment was purchased.
