This randomized controlled trial aims to evaluate the effects of an Interactive Digital Art-Based Relaxation Program on physiological parameters, anxiety levels, and emotional distress in children aged 7-12 years receiving care in a pediatric intensive care unit (PICU). Children in the intervention group will receive three short, nurse-guided digital art-based relaxation sessions delivered via tablet, while the control group will receive standard PICU nursing care. Outcomes will be assessed using physiological measurements and validated psychological assessment tools before and after the intervention.
