Read the first 7 Laser Safety & Protocols flashcards as text

  1. Which chromophore is the primary target when using a 1064 nm Nd:YAG laser for vascular lesion treatment?

    Answer: Oxyhemoglobin

    Oxyhemoglobin has an absorption peak near 1064 nm, making Nd:YAG effective for deeper vascular lesions.

  2. What is the correct response if a client experiences immediate urticarial reaction (hives) during a laser session?

    Answer: Stop treatment immediately, assess for anaphylaxis, and follow emergency protocol

    Urticaria can be an early sign of an allergic or anaphylactic reaction; treatment must stop immediately and emergency protocols must be followed.

  3. What term describes the technique of delivering laser energy in multiple rapid pulses to limit thermal diffusion to surrounding tissue?

    Answer: Selective photothermolysis

    Selective photothermolysis uses pulses shorter than the thermal relaxation time of the target to confine heat damage to the chromophore without harming surrounding tissue.

  4. Which personal protective equipment (PPE) is mandatory for both the operator AND the client during all laser procedures?

    Answer: Wavelength-specific optical density-rated eyewear

    Wavelength-specific laser safety eyewear with adequate optical density is required for all individuals in the treatment room to prevent ocular injury.

  5. A laser technician notices the treatment room door was left open during a procedure. What is the immediate priority?

    Answer: Stop firing, secure the room, and ensure no unauthorized personnel were exposed

    An open door during laser use exposes unauthorized personnel to beam hazards; firing must stop immediately and the area must be secured.

  6. What parameter directly determines the amount of energy delivered per unit area to the skin during laser treatment?

    Answer: Fluence (J/cm²)

    Fluence, measured in joules per square centimeter, is the energy density delivered to the tissue and is the primary dosimetric parameter in laser therapy.

  7. When performing laser treatment near the orbital area, which additional precaution is required beyond standard eyewear?

    Answer: Intraocular eye shields placed under the eyelids

    Intraocular metal eye shields placed beneath the eyelids provide direct protection to the cornea and lens when treating the periorbital area.
