Philips Respironics DreamStation CPAP Pro Analysis Report

Device Identification, Brand and Model Analysis

The main device shown in the visuals is a positive airway pressure (PAP) device used in the treatment of sleep apnea. The device is a modular system with an integrated heated humidifier unit. Brand and model information has been finalized as a result of a detailed examination of the warranty certificate and user manual.

• Brand: Philips Respironics
• Model Series: DreamStation
• Device Type: CPAP Pro (Defined as “DreamStation CPAP Pro, CPAP System” on the warranty certificate).
• Product Code (REF): TRX400H15

Documents and Serial Number Information

The original warranty certificate/service form and user manual are included with the product. The “Türk Philips Ticaret A.Ş.” stamp and seller company (Intermed) information on the warranty certificate confirm that the product was supplied through the authorized Turkish distributor channel. A handwritten note on the document states “Guaranteed by us for 2 years”.

Identifying Data on the Document:

• Device Serial Number (S/N): J214478271807
• Humidifier Serial Number (S/N): H214523694156
• Lot/Ref Information: +H906TRX400H150H (Data below barcode)

Visual Condition and Physical State

The cosmetic and physical condition of the device and its accessories has been thoroughly examined:

• Main Unit and Casing: The white polymer surface on the device casing appears clean. No visible cracks, fractures, heavy impact marks, or case separation have been detected. The control buttons (on/off and ramp) and the rotary navigation knob are intact and in place.
• Humidifier Unit: A transparent water reservoir and its lid are integrated into the device. No deformation has been observed in the hinge mechanism or the lid lock.
• Carrying Case: The original black carrying case with the Philips Respironics logo is present. The fabric texture is intact, the stitches are not loose, and the zipper mechanism is functional. The internal compartments are clean.

Accessories and Consumables

The following accessories, besides the device, have been identified in the visuals:

• Heated Tube (1 Unit): A white, spiral-structured heated tube with an electrical connector is present, connected to the device. It is in used condition.
• Standard Tube (2 Units): A standard air tube (RP-15MM) in its original, unopened packaging (sealed bag), transparent-white in color, is present.
• Mask and Headgear: Inside the device bag, there is one nasal or full-face mask (full type cannot be clearly distinguished from the visual) and grey headgear straps. The hard plastic parts of the mask are intact.
• Filters: Spare air intake filters are visible inside the transparent pocket on the left side.
• Documentation: A Turkish “User Manual” booklet is present.

Analysis of Deformation and Usage Marks

Critical Finding: Yellowing (oxidation) is present on the silicone/cushion parts of the mask system lying loose inside the bag. This indicates material aging due to use or time and points to the necessity of hygienic replacement. No significant yellowing or discoloration has been observed on the white plastic components of the device itself.

Mechanical and Electronic Component Analysis

No signs indicating an electronic or mechanical fault (burn marks, loose parts, screen cracks) are present on the outer casing of the device. Since the screen is off, a visual analysis of pixel errors or software status could not be performed. Power cables are loosely arranged inside the bag, but no damage or breaks in the cable sheathing have been detected on their visible parts.

Originality Assessment

Considering the molding craftsmanship, material quality, font styles on labels, carrying case, and accompanying official documents as a whole, the product has been determined to be 100% original Philips Respironics production. No evidence of aftermarket or replica parts has been found.

Areas of Use

This device is suitable for use at home or in hospitals for the treatment of patients diagnosed with obstructive sleep apnea (OSA). It maintains an open airway by applying continuous positive airway pressure (CPAP) to the respiratory tract. The humidifier unit enhances patient comfort by heating and humidifying the delivered air.

Summary and Conclusion

The Philips Respironics DreamStation CPAP Pro device is a complete set, including its bag, spare tube, and official documents. The main unit is in “clean/good” cosmetic condition. Only the yellowing on the mask silicone indicates that the consumable needs to be replaced. The 10-year spare parts availability guarantee stated in its document and official records indicate that the device’s technical service history is traceable. No physical damage has been detected on the device.
