Respironics EverFlo OPI Oxygen Concentrator Analysis Report

Overview and Device Identification

The product shown in the images is an oxygen concentrator used for patients who require respiratory support. The primary function of the device is to concentrate oxygen from the ambient air and deliver it to the patient in a purified form. The product consists of a main body, a humidifier bottle, and a power cord. The device’s wheeled structure allows it to be easily moved within a home or healthcare facility.

A total of 1 oxygen concentrator, 1 humidifier bottle attached to the device, and 1 power cord have been identified in the image.

Brand, Model, and Authenticity

Based on the logo and labels on the device, its brand is identified as Respironics and its model as EverFlo OPI. The “Respironics” brand name is located on the lower front part of the device, while the “EverFlo | OPI” label is located next to the upper control panel. OPI (Oxygen Percentage Indicator) is a feature that monitors the oxygen purity level and triggers an alarm if it falls below a certain level. The overall workmanship of the device, the quality of the logo, and the clarity of the labels give the impression that the product is authentic.

Physical Condition and Deformation Analysis

The product is generally in a used but well-preserved condition. No serious cracks, fractures, or dents are observed on its blue plastic casing. However, there are minor scratches and dirt due to usage, especially around the label on the upper part and on the general surface. No significant fading or yellowing is visible in the device’s color. The power cord is neatly wrapped around the device’s handle and shows no signs of crushing or wear.

Mechanical and Electronic Components Inspection

The mechanical and electronic components of the device appear to be in good condition based on visual inspection.

• Mechanical Components: The four black wheels located at the bottom of the device are intact and functional. The integrated handle on the top is sturdy. The flowmeter on the front panel, used for adjusting the oxygen flow, has a recessed design, which reduces the risk of breakage. The flowmeter’s scale ranges from 0 to 5 LPM (Liters Per Minute), and the ball inside is at the zero position.
• Electronic Components: The control panel features an on/off (I/O) switch and two status indicator lights. As the device is not powered on, the function of the lights could not be tested. However, there is no physical damage to the buttons.

Accessory and Equipment Evaluation

The accessories included with the device are as follows:

• Humidifier Bottle: A humidifier bottle with a transparent container, black lid, and red adjustment valve is attached to the top of the device. The bottle ensures that the oxygen is humidified before being delivered to the patient. The bottle and its connecting tube appear to be intact.
• Power Cord: The black power cord attached to the device is present in the image and has no physical damage.

No other accessories or missing parts were visually identified on the device.

Technical Information and Label Analysis

The main label detailing the device’s technical specifications (including serial number, year of manufacture, etc.) is not visible in the images. The information on the visible labels is as follows:

• Brand: RESPIRONICS
• Model: EverFlo | OPI
• Flow Capacity: The flowmeter has a scale ranging from 0.5 to 5 L/min.

Detailed technical information such as REF code, serial number, or lot number cannot be accessed from the images.

Potential Risk Assessment

Based on the visual inspection, the physical condition of the device is generally good. No significant wear, rust, or damage that could lead to an imminent failure has been observed on its casing or cables. The recessed flowmeter design provides protection against breakages, which is a common cause of failure. This assessment is a prediction based solely on external visual evidence and does not imply that the internal mechanical or electronic components are functioning perfectly. However, no significant potential risk of failure has been identified on the device in its current state.
