OxyGo Fit Portable Oxygen Concentrator

OxyGo FIT Portable Oxygen Concentrator — 2.8 lbs, Hip-Wearable, Approved for Nighttime Use

The OxyGo FIT is the smallest and lightest member of the OxyGo family — and one of the most discreet portable oxygen concentrators available anywhere. At just 2.8 lbs, it’s small enough and quiet enough to be worn directly on the hip, making it virtually invisible in everyday life. Whether you’re at home, running errands, traveling, or sleeping, the OxyGo FIT keeps going — everywhere.

Designed for 24/7 use and approved for nighttime use (without CPAP/BiPAP), the OxyGo FIT is one of the few pulse dose portable concentrators that can serve as a patient’s primary oxygen source around the clock — day and night — in a package that weighs less than a large water bottle.

The Smallest & Lightest in the OxyGo Family

The OxyGo FIT is approximately half the size of the standard OxyGo concentrator. Its ultra-compact form factor allows it to be worn on a belt clip or hip holster, carried in the included shoulder bag, or tucked into a purse or bag — without the bulk or weight of a traditional portable concentrator. For patients who have struggled with the size or weight of other POCs, the FIT is a revelation.

Intelligent Delivery Technology™ — Smarter Oxygen Delivery

The OxyGo FIT’s most clinically significant feature is its Intelligent Delivery Technology™, which goes far beyond simple pulse dose delivery:

• First 400ms Bolus Delivery: Delivers the full oxygen bolus within the first 400 milliseconds of inhalation — ensuring the oxygen reaches the lungs during the most effective phase of the breath cycle.
• Adaptive Breathing Pattern Recognition: Automatically adjusts the bolus size when breathing rate slows during sleep, rest, or relaxation — maintaining therapeutic oxygen delivery even as breathing patterns change.
• Shallow Mouth Breath Detection: Detects shallow mouth breaths that many pulse dose concentrators miss, ensuring oxygen delivery is not interrupted by irregular breathing.

This combination of features is what makes the OxyGo FIT approved for nighttime use — a distinction that most pulse dose POCs cannot claim. (Note: Nighttime approval applies to patients who do not require a CPAP or BiPAP machine.)

Three Pulse Dose Settings

The OxyGo FIT offers 3 pulse dose settings with precise, fixed output volumes:

• Setting 1: 210 mL/min
• Setting 2: 420 mL/min
• Setting 3: 630 mL/min

These three settings cover the most common low-to-moderate pulse dose oxygen prescriptions, and the Intelligent Delivery Technology ensures each bolus is delivered at the optimal moment in the breath cycle.

Up to 5 Hours Battery Life

The OxyGo FIT delivers up to 5 hours of use on a single battery charge, making it suitable for a full day of outings, appointments, or travel. The included wall charger and car charger keep the unit powered at home and on the road, and additional batteries are available for extended use.

OxyGo Mobile App

The OxyGo FIT is compatible with a free mobile app for Apple and Android devices, allowing users to monitor key information remotely:

• Battery life and charge status
• Operational status and alarm notifications
• Usage data for patient and caregiver awareness

This connectivity gives patients and caregivers greater visibility into the concentrator’s performance — particularly useful for patients who may not always be near the unit.
