• ABC (Airway, Breathing, Circulation) — A fundamental medical acronym used in cardiopulmonary resuscitation (CPR) and first aid protocols, standing for the critical steps of primary assessment and intervention: A (Airway), B (Breathing), and C (Circulation). While modern cardiac arrest guidelines often use the CAB sequence, ABC remains the cornerstone for primary trauma assessment.
• Hydrogen peroxide — A diluted aqueous solution of hydrogen peroxide (H₂O₂), typically at a three percent concentration, widely used in medicine and households due to its mild antiseptic, disinfectant, and hemostatic properties. Upon contact with damaged tissues or blood, its characteristic effervescence produces a white foam through the rapid release of atomic oxygen, mechanically cleansing wounds of debris and bacteria.
• Hydrogen peroxide — A compound form spelled with a hyphen designating a diluted aqueous solution of hydrogen peroxide (H₂O₂), typically at a three percent concentration. This pharmaceutical fluid is widely used for its mild antiseptic, disinfectant, and hemostatic properties, releasing atomic oxygen in the form of a white foam upon contact with open wounds.
• Arteriorrhagia — A massive and violent hemorrhage originating from a ruptured or severed artery, structurally characterized by the elimination of oxygenated blood (bright red color) in spurts synchronized with the heartbeats. It represents an extreme, life-threatening medical emergency due to the imminent risk of rapid hypovolemic shock.
• Splint — A rigid or semi-rigid medical device made of wood, metal, plastic, plaster, or pneumatic materials, utilized for the temporary or permanent immobilization of a fractured, dislocated, or traumatized limb, or a painful joint. Its structural role is to prevent the displacement of bone fragments, alleviate pain, and protect surrounding tissues during patient transport or throughout the healing process.
• Ambulance — A specially adapted motor vehicle equipped with specific medical apparatus and trained personnel, designed for rapid transport, emergency assistance, and first aid provided to sick, injured, or accident victims on their way to a hospital unit; an ambulance.
• Ambulance — A motor vehicle specially constructed, arranged, and equipped with medical devices, stretchers, and medications, used for providing first aid and rapidly transporting sick, injured, or accident victims to hospital units.
