Abstract: Objective: To explore the impact of active cycle breathing techniques training based on IKAP theory on dyspnea belief, peak expiratory flow rate, and exercise self-efficacy in patients with undergoing high-flow nasal oxygen therapy during ICU transition period. Methods: Patients with high-flow nasal oxygen therapy during ICU transition period were selected from a Class A tertiary hospital in Tianjin. The control group comprised 46 patients admitted from October 2021 to February 2022, who received active cycle breathing techniques training under conventional health education guidance. The observation group included 46 patients admitted from March to September 2022, who received active cycle breathing techniques training guided by the IKAP theory. The scores for dyspnea belief, peak expiratory flow rate, and exercise self-efficacy were compared between the two groups before and after the intervention. Results: The observation group had significantly lower scores for dyspnea belief, and higher scores for peak expiratory flow rate and exercise self-efficacy compared to the control group (P<0.05). Conclusion: Active cycle breathing techniques training based on the IKAP theory can reduce patients′ exercise-related fear of dyspnea, enhance their ability to cough and expectorate, and improve their confidence in physical activity.
