Physio-Control Lifepak 500 Defibrillator Analysis Report

Device Identification Brand and Model Information

Upon detailed examination of the product in the visual, it has been identified as an Automated External Defibrillator (AED) based on the text and emblem present on it. As clearly and legibly written on the device’s front panel and the instruction card inside the carrying case, the product is a Lifepak 500 model from the Physio-Control brand. Since the brand and model information is indicated on the device’s main casing with a permanent and integrated labeling system, its accuracy is absolute.

Authenticity Status

The casting quality of the device’s main casing, the neatness of the panel surrounding the user interface, and the professional integration of brand logos on the device case and carrying bag provide strong evidence regarding the product’s authenticity. The device features specific medical warning labels compliant with medical warning standards, and its color-coded medical use structure confirms that it is an original medical product manufactured to authorized producer standards.

Areas of Use

The Physio-Control Lifepak 500 is a medical device used to analyze a patient’s heart rhythm during sudden cardiac arrest due to a heart attack, and if necessary, to restore the heart to its normal rhythm by applying an electrical shock (defibrillation). It is understood from its carrying form and standby instructions that it is primarily suitable for emergency medical services, healthcare institutions, clinical environments, and first aid interventions.

Quantity and Accessory Information

The products in the visual have been carefully counted and their contents identified. The quantities of the main products and components included in the analysis are as follows.

• 1 unit main device casing (defibrillator).
• 1 unit carrying and protective bag made of special fabric with a shoulder strap.
• 1 unit quick-use instruction guide card, positioned in the upper compartment of the carrying bag, with a transparent protective sleeve.
• 1 unit package of defibrillation pads/electrodes with an “ADULT” warning band, remaining sealed in a transparent pouch.

General Condition and Physical State

The device is in good condition, well-preserved, and maintaining its structural integrity. No signs of cracking, crushing, or fragmentation were found on the outer coating and yellow protective casing. Very minor dust and lint-like superficial textures, due to use and environment, are visible on the black carrying case surrounding the device, but the fabric generally maintains structural integrity. It is determined that the device has been stored in the field but has not been exposed to extreme mechanical damage.

Electronic Components, Interface, and Button Layout

The electronic screen is off, and the device is not transmitting data in an operational state. Upon analyzing the device panel, the button layout enabling the user to manage actions is clearly readable.

• Two menu/navigation buttons with right and left arrow icons are present at the top.
• Below the screen are three main operation buttons. These are, respectively, ON/OFF (Power On/Off) on a green background, ANALYZE on a yellow background, and SHOCK on a red background.
• In the upper right part of the device interface, there is a phosphorescent or colored green circular label/marker area.
• A gray-background LCD data panel displaying digital information is positioned directly in the middle of the button layout. There is no visual breakage on the screen.

Visible Warnings and Label Information

The device’s front interface clearly displays hardware hazard and safety notifications. These warning messages, written in English along an orange line at the bottom of the front face, are as follows, verbatim.

• Full Warning Label Text: “WARNING HAZARDOUS ELECTRICAL OUTPUT. FOR USE ONLY BY QUALIFIED PERSONNEL. DANGER EXPLOSION HAZARD. DO NOT USE IN THE PRESENCE OF FLAMMABLE GASES.”
• Summary Analysis: The device contains hazardous electrical output, and information states that this product may only be used by qualified professionals or individuals with the necessary training level. An explosion warning prohibiting use in the presence of flammable/combustible gases is printed.

Usage Guidelines Analysis

The Quick Reference Guide attached to the inside compartment of the bag’s upper lid has been carefully analyzed. The heading section contains the phrase If patient is unconscious, not breathing and has no pulse then:. The instructions are presented sequentially with visual warnings and color matching.

• Green-Background Step 1: Turn on Device (matched with the green button on the device panel).
• Yellow-Background Step 2: Apply Electrode Pads.
• Red-Background Step 3: Follow Prompts.
• The device presents panel colors and guide instructions in a standardized format to maximize operational efficiency.

Size Capacity and Patient Compatibility

The product appears to have compact dimensions in a portable ergonomic design within its carrying bag form. In line with the prominent “ADULT” (Yetişkin) stamp with red-on-white emphasis on the electrode packaging found in the accessory section, the physical suitability of the spare defibrillation material provided in the package is entirely for the Adult patient class.

Visible Additional Potential Notifications and Risk Analysis

When observed through the visual, there is no clear data indicating hazardous or electronic material-damaging formations such as crushed connection plugs, liquid, or rust. Since the accessory packages are viewed from within an undeformed pouch, the existing structural system aligns with integrity. As there is no visible external damage due to physical wear and aging, it has been observed that the hardware structure of the general appearance profile does not match a non-potential sudden failure risk profile, and it is assessed to be maintained in an integrated, positive, and reasonable condition.
