The most oxygen the P2 family carries
The Rhythm P2-E7 tops the pulse range — seven settings and up to 1,400 mL/min — the most oxygen any P2 portable delivers, in the same light 4.37 lb body. If your prescription runs high, or you want headroom for altitude and exertion without stepping up to a heavy transportable, this is it. Right now it's $2,300, down from $2,900.
American Oxygen is an authorized Rhythm Healthcare dealer. Every P2-E7 is a new, genuine unit — FDA-cleared and FAA-approved — backed by the full Rhythm manufacturer warranty.Why the Rhythm P2-E7
The E7 reaches setting 7 and 1,400 mL/min — the highest pulse output in the P2 line, for prescriptions and moments a 5- or 6-setting portable can't cover.
Setting 1 runs up to 7 hours from one internal battery — the longest single-battery runtime in the family. Carry a charged spare for full travel days.
The E7 is FAA-approved for commercial flights, so it flies in the cabin with you. It's a genuine, FDA-cleared prescription medical device — not a grey-market import.
Where the P2-E7 sits in the family
Your prescribed flow setting decides the model. The E7 is the top of the range — seven settings and 1,400 mL/min in the same light body as the P2.
Bars show each model's top pulse setting. Need continuous flow instead of pulse? That's the transportable TOC3, a different category. Pulse-dose output is not equivalent to continuous-flow LPM.
Runtime across all seven settings
The E7's single battery stretches to 7 hours on setting 1 and comes down as the settings climb. Here's the full falloff (hours per charge).
Runtimes are from Rhythm's 2026 battery guide and vary with your breath rate, battery age, and temperature. Many customers carry a charged spare for long days.
Runtime by setting — exact hours
Oxygen output rises with each of the seven settings, and battery time comes down. Match your prescribed setting to plan your day.
| Pulse setting | O₂ output | Runtime per charge |
|---|---|---|
| Setting 1 | 210 mL/min | 7h 00m |
| Setting 2 | 420 mL/min | 5h 30m |
| Setting 3 | 630 mL/min | 3h 42m |
| Setting 4 | 840 mL/min | 3h 00m |
| Setting 5 | 1,000 mL/min | 2h 30m |
| Setting 6 | 1,200 mL/min | 2h 00m |
| Setting 7 | 1,400 mL/min | 1h 42m |
| Recharge — AC wall supply | up to 4 hours |
| Recharge — external charger | about 2.5 hours |
The P2-E7 holds a fixed minute-volume per setting: the bolus per breath adjusts to your breath rate to keep oxygen output steady — from 210 mL/min at setting 1 up to 1,400 mL/min at setting 7.
Which Rhythm is right for you?
The E7 is the highest-output pulse portable. Step back to the E6 if six settings are enough, or up to the transportable TOC3 if you need continuous flow.

Details
What is the Rhythm P2-E7?
The Rhythm P2-E7 is a compact pulse dose portable oxygen concentrator with seven flow settings (1–7) and up to 1,400 mL/min of oxygen — the most any P2 portable delivers — in the same 4.37 lb body. It's built for oxygen users with higher prescriptions who still want a light, cabin-friendly unit.
It is designed for users prescribed pulse dose oxygen therapy. It is not a continuous-flow concentrator — if you require continuous oxygen, look at the Rhythm TOC3 or confirm alternatives with your clinician.

- Active users at altitude or on exertion who want maximum headroom without a heavy transportable.
