RESMED S8 ESCAPE II Respiratory Device Analysis Report

Device Identification, Brand and Model Analysis

The product in the visual is a CPAP (Continuous Positive Airway Pressure) device used in respiratory therapy and sleep apnea treatment. A detailed examination of the device has conclusively identified the following brand and model information:

• Brand: RESMED
• Model: S8 ESCAPE II
• Series/Platform: S8 Series
• Technical Feature Statement: The “EPR” indication on the front panel shows that the device has the “Expiratory Pressure Relief” feature, which reduces pressure during exhalation to provide comfort to the patient.

Areas of Use

This device is typically used in the treatment of patients suffering from Obstructive Sleep Apnea (OSA) syndrome, to keep the airways open during sleep. It is suitable for home care services and hospital pulmonology departments. Thanks to its integrated humidifier chamber, it aims to prevent the patient’s airways from drying out by humidifying the delivered air.

Originality and Visual Integrity

The product’s design language, material quality, button placement, and logo prints (RESMED font and color) are consistent with original manufacturer standards. No indication of an aftermarket or counterfeit product was found.

Quantity Information

The visual shows 1 unit of the ResMed S8 Escape II main unit and 1 unit of an integrated water chamber.

General Condition and State

The device appears to be used and in medium condition cosmetically. It is clear that the device is not new, showing obvious signs of use. It is not in the condition of a display item or a new device.

Physical Deformation and Cosmetic Examination

• Front Control Panel: On the device’s dark blue glossy control panel, around the adjustment knob (dial) located on the left side, intense stains, lime-like traces, and dulling are observed. These marks are likely due to dried water splashes from the humidifier unit or cleaning chemical residues.
• Humidifier Chamber: Significant yellowing is present on the internal gaskets and plastic components of the transparent plastic water chamber. The plastic material appears to have changed color over time due to heat and water exposure. This indicates that the device has been used for an extended period.
• Casing: While no cracks or deep fissures are observed on the white outer casing, there is general surface wear.

Mechanical and Electronic Component Analysis

Screen: The device features a monochrome LCD screen. As the device was in the off position during photography, no image or error code could be read on the screen. The physical integrity of the screen appears preserved, with no cracks detected.

Keypad and Buttons: The front panel has a total of 5 gray push-buttons (On/Off, directional keys, menu keys). The symbols on the buttons are legible, but slight wear on the paint of the “Start/Stop” button is noticeable. The white rotary knob on the left (heater setting dial) is physically in place.

Accessories and Connection Points

• Water Chamber: An integrated, detachable transparent water chamber is present on the left side of the device. It has an air hose output port.
• Hose Outlet: The air outlet tube is made of transparent plastic, and its end is empty in the visual; the therapy hose is not attached.
• Cables: A gray cable end partially visible coming from the upper right side of the device, but it is not clear whether this is a power cable or another connection cable. The original power adapter or a full set of cables are not fully displayed in the visual.

Potential Malfunction Risk and Warnings

The intense staining on the device’s control panel, especially around the humidifier adjustment knob, suggests potential liquid contact in this area. This situation could create a risk of oxidation in the electronic circuits beneath the panel. Furthermore, the yellowing and aged appearance of the water chamber raise the possibility that the gaskets may have lost their sealing properties. Before use, the device must undergo a technical service check, filters should be replaced, and the condition of the water chamber should be evaluated for hygiene.
