Respironics EverFlo Oxygen Concentrator Analysis Report

Device Identification, Brand and Model

The device in the image is a stationary type oxygen production device used for medical purposes. As a result of a detailed visual inspection, the brand of the device was clearly identified as RESPIRONICS from the logo located at the bottom of the front panel. The model information of the device was determined as EverFlo based on the inscription on the upper control panel. Furthermore, the “OPI” inscription next to the model name indicates that the device has an Oxygen Percentage Indicator variation.

Overall Condition and State

Upon visual evaluation, the product appears to be in second-hand (used) condition. Although the general body integrity of the device is preserved, there are noticeable signs of cosmetic wear. Black marks, scratches, and stains caused by friction are visible in various places on the blue plastic casing. These superficial deformations are particularly noticeable on the right middle and lower sections of the front body.

Technical Details and Observed Components

The hardware and functional parts on the device are as follows:

• Flowmeter: A manual tube flowmeter is located in the middle of the front panel, allowing for flow adjustment between 0 and 5 LPM (Liters Per Minute). The ball level inside is currently at the “0” position, meaning the device is off or there is no flow.
• Control Panel: The upper left part of the device contains the On/Off switch and status indicator LED lights (green, yellow, and red warning symbols). The button and panel section appear physically intact.
• Oxygen Outlet: The metal-tipped oxygen output port is intact and in place.
• Service Label/Note: A white label with handwritten text is located on the upper right side of the device. The phrase “%94.4 working” (or a similar percentage) can be read on this label. This is an important detail indicating that the device has likely undergone a technical service test and that its oxygen purity output is around 94%, thus implying it is functional.

Areas of Use

This device is used to provide continuous oxygen support to patients suffering from respiratory failure (such as COPD, pulmonary fibrosis, etc.). It is a suitable device for use in home care services and clinical environments. It filters the air, separates nitrogen from it, and delivers high-purity oxygen to the patient.

Physical Deformation and Malfunction Risk

The outer casing of the device has cosmetic scratches and dirt that are not at a level to affect its functionality. No deep cracks or breaks were detected in the casing’s integrity. While there is no physical evidence indicating it is ‘faulty’, the handwritten note on it confirms that the device is operational. However, since the condition of the device’s filter, compressor performance, and internal components cannot be definitively known solely from visual inspection, the need for regular maintenance should not be overlooked.

Accessories and Connections

The image shows a black electric power cable wrapped around the rear/top part of the device. The humidifier water bottle or patient cannula to be connected to the device are not present in the image; only the main unit of the device is shown.

Portability and Mechanical Components

Wheels are visible at the bottom of the device. The black wheels indicate that the device has mobility. No breaks or missing parts were observed on the wheels. The integrated carrying handle on the upper part, which allows for easy transportation of the device, is in good condition.

Originality Assessment

Upon examining the device’s casing, control panel layout, logo quality, and font characteristics, the product is assessed to be an original RESPIRONICS production.

Quantity Information

There is 1 unit of oxygen concentrator in the image. (Hospital beds visible in the background are outside the scope of this analysis.)
