Inogen One G5 Portable Oxygen ConcentratorOverview

The Inogen G5 Portable Oxygen Concentrator provides supplemental 24/7 oxygen service in a compact, lightweight form so it’s easy to live life with independence.

This unIt weighs less than 6.5 pounds with the carry bag and the single-size battery. It powers from three sources – battery, AC, and DC power – to add to its travel-friendly use when traveling in a car, boat, or RV. The battery options allow users to stay out and enjoy life rather than being tethered to a cumbersome oxygen tank.

Inogen G5 Oxygen Concentrator offers pulse flow oxygen with six flow settings. It features Intelligent Delivery Technology® that senses the user's oxygen needs and matches it to the setting, even while sleeping.

Its quiet operation produces 38 decibels of noise, the sound level close to a whisper, to not keep users up at night.

Vitality Medical offers a wide variety of portable oxygen concentrators by top brands.
