Respironics EverFlo OPI Oxygen Concentrator Analysis Report

Device Identification

The product shown in the visuals is an electric, wheeled-type oxygen concentrator used for medical purposes and providing respiratory support. The device is designed to take ambient air and deliver concentrated oxygen to the patient. It has a humidifier (water reservoir) connection and related accessories.

Brand and Model

Following detailed examinations on the front face of the product and its control panel, the brand and model information has been determined as follows:

• Brand: The RESPIRONICS logo is clearly visible on the black label located on the front bottom part of the product.
• Model: The phrase EverFlo | OPI is located on the panel in the upper left corner of the device’s front. This phrase indicates that the model is “EverFlo” and that it has the “OPI” (Oxygen Percentage Indicator) feature.

Areas of Use

This device is a home-use medical device designed for patients suffering from respiratory failure or requiring additional oxygen support (e.g., COPD). It filters atmospheric air, separates nitrogen, and provides high-purity oxygen to the user.

Originality

The device’s outer casing, color tone (characteristic blue), print quality, logo placement, and control panel structure indicate that the product is an original RESPIRONICS production. Label alignments and component joints appear orderly.

Quantity Information

The visuals show 1 unit of the main device (oxygen concentrator) and 1 unit of a humidifier water container with its connecting hose, attached to the device.

General Condition

The device appears to be in good and clean cosmetic condition overall. Although it could be considered second-hand, it does not show signs of significant wear. Its casing maintains its integrity, and no visible dirt or rust is noticeable.

Physical Deformation

Upon examination of the device’s blue plastic casing:

• No cracks, breaks, or significant dents were detected on the outer casing.
• No noticeable fading or regional discoloration is visible on the surface color.
• There are no gaps in the corners or joints; the assembly integrity is sound.

Mechanical Components

The product’s mechanical parts appear visually problem-free:

• The 4 swivel wheels (casters) located at the bottom of the device are in place and appear sturdy.
• The integrated carrying handle on the upper part of the device’s body is in sound condition.
• The oxygen flow adjustment knob (flowmeter knob) on the front panel is present.
• The ball (sphere) in the flowmeter indicator and the transparent reservoir appear clean.

Electronic Components

The device’s electronic controls are located on the front panel. The black on/off switch (rocker switch) sits properly in its slot. To the left of the switch, there are 3 LED indicator light positions (indicated by icons). Since the device is in the off position, the functionality of these lights or the switch could not be tested visually.

Accessories

• Humidifier Bottle: A transparent water reservoir is present, placed in the slot at the back of the device (an area presumed to be secured with Velcro tape). The bottle’s lid is gray.
• Connecting Tubing: A short connecting tube is attached between the device’s oxygen outlet port and the humidifier bottle.

Battery Status

No external or portable battery unit is visible in the visuals. This type of device typically operates directly with mains electricity (AC). The black cable visible at the back is the device’s power connection cable.

Label Information

• Brand Label: RESPIRONICS (Lower front panel)
• Model Label: EverFlo | OPI (Upper front panel)
• Flow Indicator: The flow tube has “LPM O2” (Liters Per Minute Oxygen) written on it and numbers scaled from 0 to 5.
• Warning Icons: Bell (alarm), yellow triangle (warning), and plug/power symbols are visible on the control panel.

Dimensions and Compatibility

The device is compact and wheeled, meeting home-use standards. Although distinguishing between adult and pediatric use directly from the visual is not possible, the flow range (0-5 LPM) is suitable for standard treatment dosages. Baby use generally requires additional equipment (low-flow meter), but a standard flow meter is present in this visual.

Existing Faults

As a result of the visual analysis, no physical evidence that could be classified as a “fault,” such as broken parts, disconnected cables, or leaked fluids, was found on the device’s casing or external components. However, whether the device is in working condition cannot be determined from the visual.

Potential Fault Risk

Since the device’s external condition is clean and good, no immediate or severe potential fault risk originating from the visual is foreseen. Its physical condition is reassuring as no excessive wear is observed in cable entries or on the control panel. The condition of the internal mechanical and electronic hardware is beyond the scope of a visual inspection.
