Stay mobile with a used Rhythm P2 portable oxygen concentrator, a compact pulse‑dose machine designed for people who want lighter, more affordable portable oxygen therapy. Weighing about 4.37 lb with the battery, it is easy to carry for errands, appointments, and travel.
This unit is used and pre‑owned. It has been tested, inspected, cleaned, and sanitized to help ensure it meets quality and performance standards, but it may show normal cosmetic wear. It is best for customers who want a lower‑cost portable oxygen concentrator and understand that used devices and batteries will not perform exactly like brand‑new units.
The Rhythm P2 is a pulse dose oxygen concentrator (not continuous flow). It delivers oxygen only when it detects inhalation and offers settings 1 through 5, so your clinician should confirm that pulse‑dose therapy is appropriate for your prescription before you order.
Key specs include: weight about 4.37 lb with battery, dimensions 8.70 in L × 3.35 in W × 6.30 in H, pulse‑dose settings 1–5, oxygen concentration around 90% ± 6%, maximum oxygen output up to 1,000 ml/min, warm‑up time about 2 minutes, and AC/DC power support for home and vehicle use.
When new, the Rhythm P2 battery can provide up to 5 hours at setting 1, with shorter runtimes at higher settings; a used unit will typically deliver less runtime, depending on your setting, breathing pattern, environment, and battery condition. Many users keep a spare or replacement battery for longer days.
This used Rhythm P2 is a good fit for people prescribed pulse‑dose oxygen who want a lightweight portable oxygen concentrator for daily routines, short outings, appointments, and travel, including many seniors, COPD patients, caregivers, and anyone looking for a more budget‑friendly portable option. The manufacturer indicates that the P2 meets FAA criteria for portable oxygen concentrators, which may make it suitable for many flights; airline rules can vary, so always confirm current requirements and battery needs directly with your airline before you fly.
