Respironics EverFlo Oxygen Concentrator Analysis Report

Device Description and Intended Use

The product shown in the image is a medical oxygen concentrator. This device separates nitrogen from ambient air, leaving behind high-concentration oxygen, and is used to provide continuous flow oxygen to patients requiring respiratory support. The humidifier reservoir on the device is used to prevent the supplied oxygen from drying out the patient’s airways. Thanks to its wheeled structure, it can be easily moved in home or clinical environments.

Brand and Model Identification

As a result of detailed visual analysis, the brand and model of the device have been clearly identified. The front panel of the device displays the words Respironics, EverFlo | OPI, and Millennium. In light of this information, the device’s brand is determined as Respironics and its model as EverFlo. OPI (Oxygen Percentage Indicator) is a feature indicating oxygen percentage.

Physical Condition and Deformation Analysis

The device generally appears to be in good physical condition and is a used product. No significant cracks, breaks, or major dents were observed in the body plastic. There might be slight fading in color or minor scratches due to use, but this does not appear to affect the device’s functionality. No modification that alters its original structure has been detected, apart from a “27 V” label affixed to the power button.

Mechanical and Electronic Component Examination

No issues were detected during the visual examination of the device’s mechanical and electronic components.

• Wheels: All four wheels of the device appear intact and in place, with no deformation that would hinder mobility.
• Flowmeter: The vertical tube-shaped flowmeter, used to adjust oxygen flow rate, and the ball inside it are intact.
• Control Buttons: The power button and flow adjustment knob are in good physical condition.
• Power Cable: The black power cable and plug connected to the device show no signs of crushing or wear, as far as visible in the image.

Accessories and Equipment

The following accessories are included with the device in the images:

• Humidifier: A humidifier bottle with the word “UMIDIFICADOR” and its connection apparatus are attached to the device.
• Oxygen Tubing: A transparent tube is visible between the humidifier and the device’s oxygen outlet, likely extending to the patient.
• Power Cable: The electrical cable required for the device to operate is connected to the device.

No other accessories (e.g., nasal cannula or mask) are present in the images.

Label and Text Details

The readable text information on the device includes:

• Brand/Model Texts: EverFlo | OPI, Respironics, Millennium.
• Text on Humidifier: UMIDIFICADOR.
• Label: A label with “27 V” is on the power button.

No technical label containing the device’s serial number, REF code, lot number, or manufacturing date is visible in the images.

Overall Assessment and Conclusion

This report contains a visual analysis of a Respironics EverFlo model oxygen concentrator. Despite being used, the device is physically well-preserved and its integrity is intact. No major damages or missing parts are observed on it. Essential operating accessories such as the humidifier and power cable are present. Whether the device is functional or what its oxygen production performance level is cannot be determined solely by looking at the images. However, no serious wear, rust, or crushing in cables that could pose a potential risk of malfunction has been detected. Therefore, the visual condition of the product is positively evaluated.
