Inogen One G5 Portable Oxygen Concentrator Analysis Report

Device Identification and Brand Model Specification

The device shown in the visuals is a portable oxygen concentrator that provides respiratory support. As a result of detailed visual examinations performed on the product, the brand and model information has been confirmed:

• Brand: Inogen
• Model: One G5

The inscription “INOGENONE G5” is clearly visible vertically on the control panel on the front face of the device. This writing unequivocally verifies the product’s identity. The product features the brand’s characteristic white plastic body and a blue/grey toned keypad design.

General Condition and Physical State

The product generally appears to be in a clean and intact condition, but it is not “new” or “never used”; signs of use are present. Physical condition details are as follows:

• Casing Condition: On the device’s white plastic casing, dirt accumulations, light scuff marks, and dustings have been observed here and there, especially around the screen bezel and corners. No breakage, cracks, or deep damage that compromises the integrity of the body is visible in the image.
• Carrying Case: The device is inside an original, black carrying case specially designed for it. The case’s stitching appears robust. The mesh (gridded) sections on the sides of the case, which allow the device to ventilate, are present and do not appear torn. The case’s shoulder strap and handle are attached.
• Mechanical Components: The oxygen output nozzle (metal tip) appears intact. The carrying case’s connection clips and adjustment buckles are in place.

Electronic Components and Screen Analysis

It can be visually confirmed that the device’s electronic functions are partially operational.

• Screen Status: In the 3rd visual, the device’s LCD screen is seen to be on. The screen displays the Inogen brand’s distinctive startup logo or a standby mode icon (honeycomb/grid pattern). This indicates that the device is receiving power and the display panel is functioning. No dead pixels or signs of breakage (e.g., ink bleeding) are noticeable on the screen.
• Control Panel: The device features an On/Off button, an Audio Alert/Alarm button, and plus (+) and minus (-) adjustment buttons. The symbols on the buttons (bell, power symbol) are clear and not faded. No depressions or physical damage are visible on the buttons.

Accessories and Quantity Information

The total contents of the set in the visuals and a detailed analysis of the accessories are as follows:

• 1 Inogen One G5 Main Device: The device is placed inside the case.
• 1 Carrying Case: A black protective case with a shoulder strap, perfectly fitted for the device.
• 1 Power Adapter (Power Supply): A black power block labeled “MEDICAL AC/DC ADAPTER” is present in the visuals. The label information indicates that this adapter complies with medical device standards.
• 1 Power Cable: A cable system connected to the adapter is present.
• 1 Oxygen Cannula (Tubing): A transparent oxygen cannula/tubing is connected to the device’s metal oxygen outlet. The tubing is wrapped around the device.

Label Information and Technical Details

The technical details readable from the adapter label and extracted from the visual are as follows:

• Adapter Type: Medical AC/DC Adapter (Power supply suitable for medical use).
• User Interface: The device panel has +/- buttons for adjusting the oxygen flow level. Additionally, the visual shows an area (screen bottom left triangle exclamation mark) where battery charge level or warning symbols are located.

Originality and Battery Status

The material quality of the device, screen fonts, logo placement, and specially designed carrying case indicate that the product is an original Inogen product. It does not give the impression of an aftermarket or counterfeit product.

Note on Battery: This model (One G5) typically operates with replaceable batteries inserted into the base of the device. Although the battery size (single or double battery) cannot be fully distinguished from the visual as the device is inside the case, it can be assumed that the device has a battery for wireless operation (however, the physical condition or capacity label of the battery is not visible in the visual).

Areas of Use

The Inogen One G5 is a medical device designed for patients with an active lifestyle. It is used for the following purposes:

• To meet the oxygen needs of patients with COPD (Chronic Obstructive Pulmonary Disease).
• To provide oxygen support during travel (airplane, vehicle, walking).
• To increase patient mobility by offering a more portable solution compared to stationary home-based devices.

Current Fault and Risk Assessment

No indication that the device is displaying an “ERROR” or a “SERVICE REQUIRED” warning is present in the visuals. The screen is active. As a potential risk, the dirtiness on the device’s white surfaces may indicate the intensity of previous use; therefore, its filters (in unseen parts) may need to be checked or cleaned. However, the absence of body breakage and the robust appearance of the cables suggest that the mechanical condition is good.
