Application of load deep breathing training based on PERMA model in lung cancer patients undergoing chemotherapy

ObjectiveTo investigate the effect of load deep breathing training based on PERMA model in lung cancer patients undergoing chemotherapy.

MethodsSeventy lung cancer patients undergoing chemotherapy were selected as the study subjects, and were randomly divided into observation group and control group using a random number table method, with 35 cases in each group.The control group received routine nursing methods of chemotherapy, while the observation group received load deep breathing training based on the PERMA model, with an intervention time of 8 weeks.The changes in lung function, exercise endurance, respiratory difficulty level, and quality of life were compared between the two groups before and after the training.

ResultsAfter 8 weeks of intervention, the maximal voluntary ventilation (MVV), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and six minute walk distance (6MWD) in the observation group were higher than those in the control group (P < 0.05 to P < 0.01), MVV, FVC and FEV1 were higher than those before intervention and at discharge (P < 0.05 to P < 0.01), and 6MWD was higher than that before intervention (P < 0.05);there was a statistically significant difference in the grade distribution of modified Medical Research Council scale between the two groups (P < 0.01), the rate of grade 0 and grade 1 in the observation group was 62.85% (22/35), which was significantly higher than that of 25.71% (9/35) in the control group (χ²=9.78, P < 0.01);the emotional well-being (EWB), additional concerns-lung scores (LCS), and total scores of quality of life of lung cancer patients in the observation group were higher than those in the control group (P < 0.05 to P < 0.01), while physical well-being, EWB, functional well-being, and LCS scores were higher than those before intervention (P < 0.05 to P < 0.01).

ConclusionsLoad deep breathing training based on PERMA model can improve lung function indicators, enhance exercise endurance, reduce dyspnea grade, and improve the quality of life of lung cancer patients undergoing chemotherapy.
