Low to Medium Priority Indicators

The user-friendly display on the Inogen One G5 offers convenient monitoring of vital functions including battery life, Bluetooth connectivity, and alert volume. Intuitive sets of icons provide instant feedback on the presence of an external power source and the remaining battery level. Should the battery life dip to 10 minutes, a lower priority alert will sound, prompting you to seek an alternate power source or battery. Fortunately, with a double battery on pulse setting 2, the Inogen One G5 can deliver over 10 hours of power, making instances of low battery levels rare.

During regular breathing, a reassuring green light illuminates with each detected breath. The intelligent system of the Inogen One G5 seamlessly adapts to rest, activity, and sleep without causing unnecessary alerts. Should there be a lapse of breath detection for 60 seconds, indicating a potential issue with connectivity or cannula placement, a medium priority alert will sound.

High Priority Alerts

The Inogen One G5 employs a combination of visual and audible alerts for high priority issues, ensuring they are impossible to overlook. In the event of battery depletion, extreme temperature exposure, or battery overheating, a flashing yellow light accompanied by a series of five beeps, repeated every ten seconds, will alert you. Detection of multiple alert conditions also triggers a high priority alert. While using an oxygen concentrator requires caution, adhering to safety guidelines allows you to confidently utilize your Inogen One G5.

Adjustable Settings

Breath detection audible alerts can be easily toggled on and off, while the volume of priority alerts can be adjusted from levels 1 to 4 but cannot be silenced. Beeps accompanied by flashing lights denote the highest priority alerts, indicating conditions requiring immediate attention. Utilizing advanced algorithms and time delays, the Inogen One G5 minimizes the likelihood of false alerts while ensuring you remain informed about potential issues.

Display Icons

The LCD screen of the Inogen One G5 portable oxygen concentrator showcases an array of icons, including power status, mode, and informational notifications, providing comprehensive visibility into device functions.
