PULSE AND CONTINUOUS FLOW IN ONE PORTABLE · AUTHORIZED GCE DEALER

When pulse isn't enough — continuous flow you can carry

The GCE Zen-O is the versatile one: a portable oxygen concentrator that delivers both pulse dose and true continuous flow — 0.5 to 2.0 LPM — alongside six pulse settings. It's built for oxygen users who need more than a pulse-only unit can give: continuous oxygen for sleep or steady-flow prescriptions, plus adaptive pulse dose on the move. Two hot-swappable batteries stretch it to a full day away from the wall. It starts at $2,495.

American Oxygen is an authorized GCE Healthcare dealer. Every Zen-O is a new, genuine unit — FDA-cleared and FAA-approved — backed by the full GCE manufacturer warranty.

Why the GCE Zen-O

Continuous flow, 0.5–2.0 LPM

The Zen-O gives you true continuous flow in 0.5 LPM steps — steady liter output for sleep and higher-liter needs a pulse-only portable can't serve.

Six pulse settings, adaptive dosing

Beyond continuous flow, the Zen-O adds six pulse settings with Rate Responsive Therapy — the bolus adapts to your breathing, so one unit covers both delivery types as your day changes.

FAA-approved & FDA-cleared

The Zen-O 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.

Two ways to breathe, one unit

The Zen-O is the versatile GCE portable — continuous flow and pulse dose in a single carry-along concentrator.

Pulse-mode runtime by setting

In pulse mode the Zen-O runs across six settings. Add the second battery to roughly double your time away from an outlet (hours per charge).

Pulse-mode runtimes come from a single retail source and are approximate — they vary with your breath rate, battery age, and temperature. Confirm exact figures with our team.
Pulse setting	1 battery	2 batteries
Setting 1	4h 00m	8h 00m
Setting 2	4h 00m	8h 00m
Setting 3	3h 00m	6h 00m
Setting 4	2h 15m	4h 30m
Setting 5	2h 00m	4h 00m
Setting 6	1h 45m	3h 30m

Recharge — full charge (AC)	about 6 hours
Battery	about 1.45 lb each, user-replaceable (up to two)

In pulse mode the bolus per breath adapts to your breath rate to keep oxygen output steady across all six settings.

Continuous-flow runtime by liter setting

In continuous mode the Zen-O delivers a steady flow from 0.5 to 2.0 LPM. Higher flow draws more from the battery (hours per charge).

Continuous-flow runtimes come from a single retail source and are approximate — confirm with our team. For steady overnight or higher-liter use, plan your runtime with margin and carry a charged spare.
Continuous flow	1 battery	2 batteries
0.5 LPM	3h 00m	6h 00m
1.0 LPM	1h 45m	3h 30m
1.5 LPM	1h 15m	2h 30m
2.0 LPM	45m	1h 30m

Continuous flow is a true steady liter output — the delivery type most often prescribed for sleep and higher-liter needs.

Which GCE is right for you?

The Zen-O is the versatile one — the only GCE portable with continuous flow. If you only need pulse dose in the lightest body, the Zen-O Lite may fit you better.

Details

What is the GCE Zen-O?

The GCE Zen-O is a portable oxygen concentrator that delivers both continuous flow (0.5–2.0 LPM) and six pulse settings in one unit. It uses GCE's Rate Responsive Therapy to adapt the pulse bolus to your breathing, and it takes up to two hot-swappable batteries for a full day away from the wall.

It's built for oxygen users who need more than a pulse-only portable — continuous oxygen for sleep or steady-flow prescriptions, plus pulse dose on the move. If continuous flow isn't part of your prescription and you want the lightest unit, look at the Zen-O Lite.

Who it's for

Continuous-flow users who need a steady 0.5–2.0 LPM for sleep or steady-flow prescriptions.
Users who need both modes — continuous at night, pulse on the move — from a single portable.
Travelers — FAA-approved for flights, with two batteries for a full day out.

Confirm your prescription, flow type, and required setting with your clinician.

Frequently asked questions

Does the Zen-O really do continuous flow?

Yes. The Zen-O delivers true continuous flow from 0.5 to 2.0 LPM in 0.5 steps, plus six pulse settings — it's the versatile GCE portable that covers both delivery types. That makes it suitable for many sleep and steady-flow prescriptions a pulse-only unit can't serve.

How long does the Zen-O battery last?

In pulse mode, up to about 4 hours on one battery at setting 1 and up to 8 hours with two. In continuous mode, about 3 hours at 0.5 LPM on one battery, coming down as the liter setting rises. Runtime varies with conditions — carry a charged spare for long days.

Is the Zen-O approved for airline travel?

Yes. The Zen-O 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 Zen-O 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?

Yes. American Oxygen is an authorized GCE dealer. Every Zen-O is new and genuine, backed by the GCE manufacturer warranty — 3 years unit, 1 year sieve columns, 1 year battery — plus our local support.
