Aim: This study aimed to enhance conscious awareness of respiratory control in panic disorder patients to prevent panic attacks. Materials and Method: Thirty participants (aged 18–65) diagnosed with panic disorder were recruited from NP Istanbul Brain Hospital and NP Istanbul Medical Center. They were divided into two groups: one received only psychoeducation on breathing techniques, while the other received psychoeducation combined with visual biofeedback (Galvanic Skin Resistance, heart rate, respiratory depth, and skin temperature). Breathing training was conducted over four weeks, and outcomes were assessed using the Panic Agoraphobia Scale, State and Trait Anxiety Scale, and biofeedback metrics. Result: Both groups showed significant improvements in Panic Agoraphobia Scale scores and reductions in State and Trait Anxiety scores. The biofeedback group demonstrated more pronounced improvements in respiratory control, with significantly lower breathing rates in the final assessment. Conclusion: Respiratory biofeedback combined with psychoeducation effectively improves respiratory control and reduces anxiety symptoms in panic disorder patients.
