The Importance of Breathing Training in Folk Dance Teaching

The importance of breathing training in dance teaching is reflected in the two aspects of enhancing the quality of dance movements and sublimating the connotation of dance movements.For example,high-quality breathing can help performers complete the dance movements and improve the coordination of the movements;at the same time,the unique body rhythm formed by breathing can strengthen the visual effect of the performance and convey its spirit and soul to the audience.This requires folk dance teachers to carry out relevant training and teaching activities based on the categories and skills of dance breathing,such as changing students’ideological cognition,developing periodic breathing training courses,providing personalized guidance to students,and allowing students to adjust their learning and practice methods in the evaluation.

Application Effect of External Diaphragm Pacemaker Combined with Active Respiratory Circulation Technology in Pulmonary Rehabilitation of Perioperative Lung Cancer Patients

Aim: To explore the application effect of external diaphragm pacemaker combined with active respiratory circulation technology in pulmonary rehabilitation of perioperative lung cancer patients. Methods: A total of 98 lung cancer patients admitted to our hospital from April 2020 to November 2021 were selected as the observation objects, and then divided into a control group and an observation group using the random number table method, with 49 cases in each group. The control group received routine admission guidance and active respiratory circulation training, while the observation group was supplemented with external diaphragm pacemaker on the basis of the control group. The intervention effect was evaluated by blood gas indicators, pulmonary function indicators, diaphragm function indicators, sputum comfort degree, and activity tolerance indicators before and after intervention. Results: Before intervention, there were no significant differences in blood gas analysis indicators, pulmonary function indicators, diaphragm function indicators, sputum comfort degree, and activity tolerance indicators between the two groups (P > 0.05). After intervention, the improvement degree of the above indicators in the observation group was higher than that in the control group (P < 0.05). Conclusions: The application of external diaphragm pacemaker combined with active respiratory circulation technology in pulmonary rehabilitation of perioperative lung cancer patients is significant, which can effectively improve the pulmonary function, blood gas function, and diaphragm function of lung cancer patients after surgery, and improve the activities of daily living and quality of life of patients.

Effects of Breath Training Pattern “End-Inspir atory Pause” on Respiratory Mechanics and Arterial Blood Gas of Pa tients with COPD

Objective: In order to explore the mechanism of C hinese traditional breath training, the effects of end-inspiratory pause br eathing (EIPB) on the respiratory mechanics and arterial blood gas were studied in patients with chronic obstructive pulmo nary disease (COPD).Methods: Ten patients in steady stage participating in the stud y had a breath training of regulating the respiration rhythm as to having a pause betw een the deep and slow inspiration and the slow expiration.Effect of the training was observed by visual feedback from the screen of the re spiratory inductive plethysmograph. The dynamic change of partial pressure of oxygen saturation in blood (SpO 2) was recorded with sphygmo-oximeter, the pulmonary mechanics and EIPB were determined with spirometer, and the data o f arterial blood gases in tranquilized breathing and EIPB were analysed.Results: After EIPB training, SpO 2 increased progressively, PaO 2 increased and PaCO 2 decreased, and the PaO 2 increment was greater than the PaCO 2 decrement. Furthermore, the tidal volume increased and the frequency of respira tion decreased significantly, both inspiration time and expiration time were prolonged. There was no significant change in both mean inspiration flow rate (VT/Ti) and expir ation flow rate (VT/Te). The baselines in spirogram during EIPB training had no raise. Conclusion: EIPB could decrease the ratio of the dead space and ti dal volume (VD/VT), cause increase of PaO 2 more than the decrease of PaCO 2, suggesting that this training could impro ve both the function of ventilation and gaseous exchange in the lung. EIPB training might be a breath ing training pattern for rehabilitation of patients with COPD.
