THE ONLY RHYTHM WITH CONTINUOUS FLOW · AUTHORIZED RHYTHM DEALER
When pulse isn't enough — continuous flow you can travel with
The Rhythm TOC3 is the one transportable in the family that delivers continuous flow — 1.0 to 3.0 LPM — alongside ten pulse settings. It's built for oxygen users who need continuous oxygen for sleep, higher-liter prescriptions, or conditions a pulse-only portable can't serve, and still want something they can wheel through an airport.
American Oxygen is an authorized Rhythm Healthcare dealer. Every TOC3 is a new, genuine unit — FDA-cleared and FAA-approved — backed by the full Rhythm manufacturer warranty.Why the Rhythm TOC3
Continuous flow, 1.0–3.0 LPM
The only Rhythm portable with true continuous flow — five levels from 1.0 to 3.0 LPM in 0.5 steps — for prescriptions and sleep needs that a pulse-only unit can't meet.
Ten pulse settings too
Beyond continuous flow, the TOC3 adds ten pulse settings with adaptive dosing — so one unit covers both delivery types as your needs change through the day.
FAA-approved & FDA-cleared
The TOC3 is FAA-approved for commercial flights, so it travels in the cabin with you. It's a genuine, FDA-cleared prescription medical device — not a grey-market import.
Two ways to breathe, one unit
The TOC3 is the only Rhythm that gives you both continuous flow and pulse dose in a single transportable.

Pulse-mode runtime by setting
In pulse mode the TOC3 runs across ten settings. Here's the runtime per charge at each (hours per charge).
| Pulse setting | Runtime per charge |
|---|---|
| Setting 1 | 6h 36m |
| Setting 2 | 4h 54m |
| Setting 3 | 3h 54m |
| Setting 4 | 3h 36m |
| Setting 5 | 3h 18m |
| Setting 6 | 3h 00m |
| Setting 7 | 2h 36m |
| Setting 8 | 2h 18m |
| Setting 9 | 2h 00m |
| Setting 10 | 1h 48m |
| Recharge — AC wall supply | up to 4.5 hours |
| Battery weight | about 4 lb, user-replaceable |
In pulse mode the bolus per breath adapts to your breath rate to keep oxygen output steady across all ten settings.
Continuous-flow runtime by liter setting
In continuous mode the TOC3 delivers a steady flow from 1.0 to 3.0 LPM. Higher flow draws more from the battery.
| Continuous flow | Runtime per charge |
|---|---|
| 1.0 LPM | 3h 06m |
| 1.5 LPM | 2h 30m |
| 2.0 LPM | 1h 54m |
| 2.5 LPM | 1h 24m |
| 3.0 LPM | 1h 12m |
Continuous flow is a true steady liter output — the delivery type most often prescribed for sleep and higher-liter needs.
Which Rhythm is right for you?
The TOC3 is the only Rhythm with continuous flow. If pulse dose covers your prescription, the lighter E7 may be the better fit; if you need continuous oxygen, the TOC3 is the one.
| P2-E7 | Rhythm TOC3 | |
|---|---|---|
| Flow type | Pulse only | Pulse + continuous |
| Continuous flow | — | 1.0–3.0 LPM (0.5 steps) |
| Pulse settings | 1–7 | 1–10 |

Details
What is the Rhythm TOC3?
The Rhythm TOC3 is a transportable oxygen concentrator that delivers both continuous flow (1.0–3.0 LPM) and ten pulse settings in one unit. It's the only continuous-flow model in the Rhythm portable range, built for users who need continuous oxygen for sleep or higher-liter prescriptions but still want to travel.
At 17.2 lb with its battery it rolls easily but is heavier than the pulse-only P2 portables. If pulse dose covers your prescription, a lighter model may suit you better — ask us and we'll help you decide.
Who it's for
- Continuous-flow users who need a steady 1.0–3.0 LPM for sleep or higher-liter prescriptions.
- Users who need both modes — continuous at night, pulse on the move — from a single transportable.
- Travelers — FAA-approved for flights, so continuous-flow oxygen can go in the cabin with you.
Confirm your prescription, flow type, and required setting with your clinician.

Frequently asked questions
Does the TOC3 really do continuous flow?
Yes. The TOC3 delivers true continuous flow from 1.0 to 3.0 LPM in 0.5 steps, plus ten pulse settings — it's the only Rhythm portable that offers continuous flow. That makes it suitable for many sleep and higher-liter prescriptions a pulse-only unit can't serve.
How long does the TOC3 battery last?
In pulse mode, up to about 6.6 hours on setting 1. In continuous mode, about 3 hours at 1.0 LPM, coming down as the liter setting rises. Runtime varies with conditions — carry a charged spare for long days.
Is the TOC3 approved for airline travel?
Yes. The TOC3 is FAA-approved for use on commercial flights and travels in the cabin with you. Airlines typically ask for advance notice and enough charged batteries for about 150% of your flight time.
Do I need a prescription to buy it?
Yes. The TOC3 is an FDA-cleared prescription medical device. American Oxygen can help you understand what's needed — just ask when you call.
Is this a new unit with warranty?
