ObjectiveTo summarize and analyze the standardized operational procedure and preliminary clinical outcomes of a "three-dimensional integrated" respiratory training model, and to propose a safe adjunctive intervention for the perioperative management of lung nodule ablation. MethodsClinical data from patients who underwent lung nodule ablation at West China Hospital, Sichuan University from August to December 2025 were consecutively enrolled and analyzed. Results A total of 18 patients were included, comprising 10 males and 8 females, with a mean age of (62.8±11.2) years. Following the implementation of the preoperative "three-dimensional integrated" respiratory training model, the mean breath-holding time significantly increased from (22.9±7.5) s at admission to (32.6±6.9) s preoperatively (P<0.01). The volume measured on the respiratory trainer improved from a mean of(1 247.2±518.9) mL at admission to (1 550.0±546.1) mL preoperatively (P<0.01). Ablation modalities included radiofrequency ablation in 17 (94.4%) patients and cryoablation in 1 (5.6%) patient. During the ablation procedure, the mean number of needle adjustments was (1.4±0.8) times, and the mean localization time was (15.6±4.4) min. All patients successfully completed the ablation therapy, achieving a technical success rate of 100.0% with no intraoperative complications. ConclusionThe "three-dimensional integrated" respiratory training model effectively enhances patients' surgical tolerance, cooperation, and procedural precision. It offers a new, safe, and effective perioperative management strategy, especially for high-risk patients (e.g., the elderly or those with poor lung function) who may be unable to tolerate conventional surgery. This model demonstrates promising potential for widespread clinical application.
