This book focuses on the use of photobiomodulation in wound care, grounded in scientific principles and the best available evidence. It encourages professionals to reflect on Evidence-Based Practices and Evidence-Based Nursing, thereby empowering nurses to play an essential role in wound care. This book equips nurses to deliver high-quality, effective care. It covers the history of biophotonics, the physical principles of light and its interaction with biological tissues, and aspects of dosimetry and treatment individualization. This includes using the correct technique, preparing the wound bed to receive light, and the necessary posttreatment care. It also addresses the main clinical indications and contraindications for low-level laser therapy, how to select the ideal light based on the healing stage and the wound's specific conditions, and demonstrates successful clinical cases involving photobiomodulation.
