Inogen One G4 POC with Pulse Dose Overview
Tired of the expense and hassle of tanked oxygen? The Inogen One G4 Portable Oxygen Concentrator creates its own oxygen supply from the surrounding air, and is the most portable oxygen concentrator on the market today, weighing in at only 2.8 pounds-- almost half the weight of the Inogen G3. It's small enough and light enough to be carried like a purse or tote bag, with a shoulder strap that connects to the machine directly.
The machine provides pulse dose oxygen therapy, and it's quiet enough to be used in almost any environment or situation such as a meeting, presentation, movie or play. The noise output from the device measures only 40 decibels. It's also FAA certified, meaning that it's approved for in-flight use.
It comes with a 4 Cell Lithium-Ion Rechargeable Battery that can provide up to 2.7 hours of run-time. Or, you can upgrade to a package that includes an 8 Cell Extended Battery, providing nearly 5 hours of run time (at the lowest flow rate setting)! That's more time with family, more time shopping, and more time doing enjoyable activities!
The Inogen One G4 Portable Oxygen Concentrator is the latest in a series of innovations and breakthroughs from Inogen Oxygen. It's a compact, lightweight unit and features several advances over the Inogen One G3. This concentrator provides pulse dose oxygen flow only.
It's almost half the weight, weighing in at 2.8 pounds and feels like carrying a purse or a briefcase on the shoulder. It's more portable, and has 3 different flow rates that synchronize to each breath, delivering oxygen within 400 milliseconds. It's also FAA certified for in-flight use, and can go almost anywhere.
A quiet unit at only 40 decibels, the Inogen One G4 can be used almost anywhere, without disturbing others. It's quiet enough to be taken to a meeting, library, or movie. It generates its own oxygen from the surrounding air, thus eliminating dependence on tanked oxygen for good.

Weighs Only 2.8 Pounds - Almost Half the Weight of the Inogen G3!
Whereas tanked oxygen is bulky and inconvenient, the Inogen One G4 is fully portable. It weighs in at 2.8 pounds, almost HALF the weight of the Inogen One G3. It's more portable and feels almost like carrying a briefcase or purse. It comes with a shoulder strap that attaches directly to the machine, making it easy to carry.
FAA Certified for In-Flight Use
The Inogen One G4 can go almost anywhere, including an airplane! Like its predecessor, the Inogen G3, the Inogen G4 can be used on an airplane according to current FAA regulations. It's important to check with the airline first, before flying, as regulations can change and some airlines have different rules as to the types of devices they permit.
Quiet Unit Operates at 40 Decibels
The Inogen One G4 Portable Oxygen Concentrator is quiet enough to not disturb others. Operating at 40 decibels, it's one of the quietest oxygen concentrators ever built.
Pulse Dose Flow Provides Oxygen on a Breath-by-Breath Basis
The Inogen One G4 is smart enough to detect when each breath is taken, and then almost immediately apply the needed oxygen-- within 400 milliseconds. This is considered optimal for oxygen therapy since this is the timeframe in which oxygen has the best chance of being absorbed by the lungs. Pulse dose concentrators supply oxygen on a breath-by-breath basis while continuous flow models supply oxygen continuously.
3 Different Flow Settings
Adjusting the flow rate on the Inogen One G4 is fairly easy with three available presets. The Inogen One G4 simplifies things by having three settings that allow for optimal flow.
Generates Oxygen from the Surrounding Air
An oxygen concentrator eliminates the need for tanked oxygen by filtering out other gasses from the outside air and turning it into mostly pure oxygen that is delivered to the nose through a device known as a cannula. The Inogen One G4 is lightweight and portable, bringing new independence for people that require constant oxygen therapy.
Included 4 Cell Battery Lasts Roughly 2 Hours
The included 4 cell battery lasts roughly 2 hours (depending on pressure setting) allowing for your oxygen therapy, even away from home. The OPTIONAL 8 cell battery provides almost double the amount of time as the 4 cell battery, providing roughly 4 hours of runtime depending on flow rate.

Oxygen Safety Tips
Overall, portable oxygen is very safe to use. It's important to remember that oxygen is a flammable gas, and if ignited, it can lead to serious injury or death. It's important to follow some basic common-sense ground rules when using oxygen.
- Avoid the following: matches, cigarettes, cigarette lighters. Be extremely careful around any source of open flames, as open flames risk injury or death while using oxygen.
- It's important to only use water-based lotion and not petroleum-based lotions for skincare.
- Do not use oxygen therapy around stoves, burners, or bonfires.
- At best, stay at least 5 feet away from any heat sources. It's recommended there is no smoking in any room where oxygen is used, even by persons who are not using oxygen therapy.
Using an Oxygen Concentrator in a Car
- Only use the concentrator while the car is running.
- Be sure to start the car before turning on the Inogen G4.
- Do not leave the machine in a hot car.
Additional Safety Precautions
- The inlet vent and outlet vent on the Inogen G4 should never be blocked. It's recommended to use the carrying case that comes with the machine, as its design is specific to the Inogen G4 and will not block the vents.
- The Inogen One G4 should never be started cold. If in a cold climate, please allow the Inogen G4 to warm up before starting.
- The Inogen G4 is not waterproof or water resistant. It is not designed to get wet. If it gets wet, it may become damaged or destroyed. When cleaning the device, use a damp cloth to wipe down the unit.
Getting Started with the Inogen G4 - Setup Instructions
- Choose a table or other flat surface near a power outlet to unbox the item. Operating the unit requires being in a space with plenty of ventilation, and the inlet and outlet vents should not be blocked.
- After unboxing, make sure the particle filters are installed before continuing with the setup of the Inogen G4.
- Take the battery, and slide it into place in the slot at the bottom of the machine.
- Connect the AC power adapter to the slot for the power supply, located near the bottom of the machine. The green LED will light up and the machine will beep.
- Connect the nasal cannula to the nozzle fitting on the top of the machine. The manufacturer recommends using a cannula that is no more than 25 feet in length for optimal oxygen flow.
- Turn on the Inogen G4 by pressing the ON/OFF power button. The machine will emit a single loud beep, and then a message saying "PLEASE WAIT" will appear on the LCD screen while the concentrator sets up.
- Use the + or - buttons to set the flow rate prescribed by your physician.
- Place the cannula comfortably on the face and begin to breathe. The Inogen G4 can detect each breath, and the status light will flash green each time a breath is detected. If a second breath comes too quickly after the first, the Inogen G4 may ignore the second breath, giving the appearance of a missed breath. This is normal behavior, as the Inogen G4 automatically adjusts to detect changes in breathing. The Inogen G4 should sense the next breath, and supply oxygen accordingly.
PLEASE NOTE: The Inogen G4 can operate using the battery alone or while plugged in.
Battery Charging and Use Tips
The Inogen One G4 Portable Oxygen Concentrator uses a lithium-ion rechargeable battery. The device can run completely off of battery power if needed, or it can run while plugged into the wall. If depleted, it can take up to 4 hours to fully recharge the battery.
The Inogen One G4 comes with an AC Power Supply and a DC Charging Cable (which plugs into the cigarette lighter in a car). The battery can be charged from either power source. The battery is designed to be charged while the unit is plugged in, as long as the battery is attached.
The Inogen G4 ships with a 4 cell lithium ion battery, which is good for up to 2.7 hours of runtime. The OPTIONAL 8 cell lithium ion battery provides up to 5 hours of runtime. Runtimes may vary, depending on what the flow rate is.
How to Check the Battery Level?
The battery level is displayed as a percentage on the LCD screen. To preserve the longevity of the lithium-ion battery, it's recommended to avoid over-depletion.
Most Common Cannula Questions
How Should I Connect the Cannula to the Machine?
There's a metal prong sticking out of the top of the machine. This is where the oxygen is released. Remove the cannula from the packaging, and connect the bottom of the tube into the metal prong on the Inogen G4. It's now ready to deliver oxygen.
What's the Best Way to Position the Cannula Tube?
Simply position the cannula on the face, so the nasal prongs are pointing upward into the nose. The sides should drape over the ear, creating a stable, comfortable fit.
How Can the Flow be Adjusted?
The flow can be easily adjusted by pressing the + or - buttons on the top of the machine. It's important to note that flow rate is the dosage of oxygen and must be set by a physician.
Important Filter Information
The filters are meant to work for the life of the device and do not need to be replaced, except in case of damage. If the filters become damaged they must be replaced before continuing with use.
AC Power Supply 100 -240 V
The included AC Power Supply features a two-pronged design compatible with US and Canadian outlets. The power supply is rated for 100 - 240 volts which means it can work internationally in most countries without needing an extra device to convert the voltage.
To use internationally, a plug adapter kit is needed. CPAP.com sells a plug adapter kit for international use, which can be found by following the link.
DC Power Cable
The Inogen G4 Oxygen Concentrator comes with a DC Power Cable. It's designed to plug into a cigarette lighter in a car or boat to power the Inogen G4 while on the go.
