Description

The Rhythm P2 Portable Oxygen Concentrator from Rhythm Healthcare is a lightweight, pulse dose oxygen device built for people who want mobility without sacrificing reliability. Weighing just 4.37 lb, it's designed for seniors, caregivers, COPD patients, and travelers who need a compact solution for everyday supplemental oxygen.

This model delivers pulse dose oxygen only across five adjustable settings, with battery runtime ranging from up to 5 hours at setting 1 down to about 1 hour 50 minutes at setting 5. The P2 meets manufacturer-stated FAA acceptance criteria and is commonly used for air travel, though airline requirements vary and should always be confirmed before flying.

With flexible AC and DC power options, a simple color display, and quiet operation, the Rhythm P2 is built for straightforward daily use at home, during errands, or on the road.

Important: This is a pulse dose device only — it does not provide continuous flow. Always follow your physician's prescription when selecting a setting.

Product questions & answers

Is the Rhythm P2 a continuous flow or pulse dose device?
The Rhythm P2 is a pulse dose oxygen concentrator only. It delivers oxygen when it detects inhalation and does not provide continuous flow. Always follow your physician's prescription when choosing a device and setting.

Can I use the Rhythm P2 on a flight?
The P2 meets manufacturer-stated FAA acceptance criteria and is commonly used for air travel. However, airline requirements and battery documentation policies vary, so confirm with your specific carrier before flying.

How long does the battery last?
Battery runtime depends on your setting: up to 5 hours at setting 1, decreasing to about 1 hour 50 minutes at setting 5. Runtime also varies with breathing rate, environment, and battery age.

Can I extend battery life for longer days?
Yes. Many users carry a spare battery or use an external battery charger to extend usage time beyond a single charge.

How do I set up the Rhythm P2?
Insert the battery until it clicks into place, attach a nasal cannula to the oxygen outlet, press the power button, and allow the warm-up period. Adjust the setting (1–5) according to your prescription and ensure the unit is well-ventilated during use.

Does Order Your Supplies provide an insurance receipt for this purchase?
Most products are sold as cash-pay purchases. After your order is placed, you can request an insurance-ready receipt that includes the item description, cost, and applicable HCPCS code. You can then submit it to your insurance provider to ask about out-of-network or self-purchase reimbursement if your plan allows it.
