With flow settings 1-6, the Inogen One G5 delivers 24/7 oxygen delivery in a robust yet compact package. With the Inogen One G5, you can comfortably run errands, take a weekend trip to see family, or even enjoy an overseas vacation!
The Inogen One G5 is a travel-friendly device that meets FAA requirements and delivers an ultra-quiet operation.
Operating at a whisper-quiet 39 decibels, this feature allows you to engage in daily activities and social gathering without the intrusion of noise typically associated with oxygen therapy, ensuring privacy and comfort in any setting.
The Inogen One G5 features Intelligent Delivery Technology, optimizing oxygen delivery to your natural breathing rhythm. This advanced system delivers oxygen precisely when you need it during inhalation, ensuring optimal oxygen saturation without wasting energy.
Weighing as little as 4.7 lbs. with a single battery and 5.7 lbs. with the extended-life battery, the Inogen One G5 offers portability and convenience for active lifestyle. FAA-compliant for air travel empowers users with the freedom to explore and travel with confidence, knowing their oxygen therapy needs are seamlessly met on the go.
The Inogen One G5 sets a new standard for silent operation in portable oxygen concentrators. With its whisper-quiet 39 decibels at setting 2, you can use it any time, without worrying about noise, day or night. This minimal noise level ensures that your oxygen therapy remains a private part of your life, allowing you to participate in social activities or enjoy peaceful moments without drawing attention.
The Inogen One G5 portable oxygen concentrator incorporates Inogen's patented Intelligent Delivery Technology, a sophisticated system designed to optimize oxygen delivery in sync with your natural breathing rhythm. This technology ensures oxygen is efficiently released during the initial 400 milliseconds of inhalation—where it's most beneficial for lung gas exchange. What sets the G5 apart is its intelligent pulse dose delivery, a feature that seamlessly adjusts to your breathing patterns. By detecting the onset of inhalation, it delivers oxygen precisely when you need it, ensuring no waste while maintaining optimal oxygen saturation. This responsiveness not only conserves energy but also reduces noise.
The Inogen One G5 is one of the lightest portable oxygen concentrators available, weighing only 2.2 kg (4.7 lbs.) with a single battery and 2.6 kg (5.7 lbs.) with the extended-life battery. Its compact size ensures easy transport and flexibility for daily activities.
The Inogen One G5 meets FAA requirements for air travel, ensuring you can carry it on commercial flights without issues. This approval offers peace of mind for travelers who rely on supplemental oxygen. To ensure you have no problem with your Oxygen Concentrator equipment, it's advised to contact your airline at least 48 hours before your flight to verify their policies on using the G5 or any other Oxygen Concentrator during the flight, as some may provide onboard electrical power for the device or specific restrictions. If onboard power is not an option, plan to bring enough batteries to cover 150% of your flight's duration. This preparation allows you to maintain your uninterrupted oxygen therapy.
The Inogen One G5 portable oxygen concentrator features a design that is as discreet as it is stylish, matching the size of a small purse or shoulder bag. This careful design consideration ensures that it blends seamlessly into your daily life, offering oxygen therapy without drawing attention.
This Oxygen Concentrator is designed with ease of use at its core, featuring a LCD display that simplifies monitoring for even new oxygen therapy users. The screen provides clear feedback on the current oxygen flow setting and the remaining battery life, ensuring users can stay informed. Indicator lights next to the screen offer visual signals regarding the machine’s status; a green light signals normal operation with successful breath detection, while a yellow flash alerts users to a low battery or maintenance requirements, minimizing guesswork and enhancing safety. Adjusting oxygen flow is just as simple as pressing the +/- buttons, making it accessible for users of all ages and technical abilities.
