Inogen One G4 Oxygen Concentrator

The Inogen One G4 is officially the smallest and lightest portable oxygen concentrator ever released by Inogen.


Priced at $4355.99, the Inogen One G4 oxygen concentrator is considered to be the smallest and lightest portable oxygen concentrator capable of providing oxygen 24/7 in an extraordinarily small package.

Despite the small size, the Inogen One G4 is unbelievably powerful. It has a pulse flow delivery system which means that it does not offer continuous flow. Instead, it is fitted with Inogen’s standard intelligent delivery technology to make sure the unit identifies your breath to deliver the oxygen with extreme preciseness.

Cost Conscious

Using an oxygen tank is costly as it involves buying a new one when the supply runs out.  But an oxygen concentrator does not have to be replaced as it will supply unlimited oxygen therapy on demand and the cost is only one payment when the device is purchased.

Social and health benefits

A patient could significantly reduce risks of complications related to COPD such as pulmonary hypertension, heart failure by inhaling pure oxygen with the aid of a concentrator.

Many patients suffer from shortness of breath and best relief is by getting the correct amount of therapeutic oxygen into the bloodstream.

Quality of life can be improved. The proper oxygen treatment will help you to improve your mood and enjoy life. You will be able to sleep better and gradually symptoms of depression will disappear when all the organs get the correct amount of quality oxygen and on the whole, make you feel and look better.

Risk of hypoxemia can be reduced. Shortness of breath, wheezing, confusion and sometimes the skin turning blue are some of the symptoms of hypoxemia. Getting pure grade oxygen in the system reduces these symptoms.


Additional Benefits

  • It doesn’t need oxygen refills or heavy tanks
  • Manufactured to suit travel use, portable or stationary locations.
  • Easy to travel in a pack.
  • Minimal maintenance.
  • In accordance with FAA requirements for airline travel


This unit is definitely much safer than an oxygen tank. Several decades back large oxygen tanks were used as the best option for oxygen therapy patients. However, today Imogen One G4 concentrator is considered the best choice. While oxygen tanks are exposed to the risk of leakage, oxygen concentrators do not have any risk of leakage. Leaks could probably trigger inflammability but this will never occur in a home oxygen concentrator as it generates oxygen only on demand and delivers it through a nasal cannula conveniently and safely.

How Inogen G4 can help with Oxygen Therapy


Oxygen is a gas that a human body requires to function or live. Usually, oxygen is absorbed by the lungs when you breathe air. However, those suffering from diseases such as chronic obstructive pulmonary known as COPD do not get sufficient oxygen due to breathing difficulties. Such patients are treated with oxygen therapy to provide the extra oxygen required.

Oxygen concentrator or Oxygen generator is a medical tool used to deliver oxygen to those who have a medical problem that results in low levels of oxygen in their blood.


An oxygen concentrator/generator cannot be bought over the counter and sold only doctor’s prescription. These are usable by electric or battery operation. It has a compressed element and should not be mixed up with a compressed oxygen or an oxygen tank. A concentrator or generator filters the air, condenses and distributes the air continuously whilst the tank has a fixed amount of oxygen to dispense. The air supply in an oxygen concentrator/generator will never run out. It only needs a power connection to operate.

How does an Oxygen Concentrator Operate?

An oxygen concentrator operation is similar to a window air conditioning unit. It absorbs air, transforms and delivers it as new purified air. This is very useful to those in need of medical oxygen due to low oxygen levels in their blood.


  • Air from the atmosphere is taken into the lungs
  • Cooling mechanism keeps the concentrator from overheating when the air is being restricted.
  • Nitrogen is removed from the air through the filter and sieve beds.
  • Delivery settings of air are adjusted with an electronic fuse.
  • Purified oxygen is delivered through a nasal cannula or mask.
