Effect of Active Respiratory Cycle Training Assisted Non-Invasive Ventilator Therapy on Symptom Remission Time and Lung Function in Patients with Pulmonary Heart Disease and Respiratory Failure
Objective To investigate the effect of active respiratory cycle training assisted non-invasive ventilator therapy on symptom remission time and lung function in patients with pulmonary heart disease and respiratory failure. Methods A total of 82 patients with pulmonary heart disease and respiratory failure treated in Dingtao District Hospital of Traditional Chinese Medicine of Heze City from October 2020 to October 2023 were selected as research objects,and were divided into a control group and an observation group according to random number table method,with 41 cases in each group. The control group was treated with non-invasive ventilator,and the observation group was treated with active breathing cycle training on the basis of the control group. The blood gas analysis indexes,symptom remission time,lung function and heart function were compared between the two groups. Results The relief time of severe cough,chest tightness,palpitation and dyspnea in the observation group were shorter than those in the control group,and the differences between groups were statistically significant (P<0.05). After intervention,the level of arterial partial pressure of oxygen (PaO2) was higher than before intervention,and the level of arterial partial pressure of carbon dioxide (PaCO2) was lower than before intervention,and the level of PaO2 in the observation group was higher than that in the control group,and the level of PaCO2 was lower than that in the control group,with statistical significance (P<0.05);the forced expiratory volume in one second (FEV1),peak expiratory flow rate (PEF) and forced vital capacity (FVC) of the two groups were greater than before intervention,and FEV1,PEF and FVC of the observation group were greater than those of the control group,the differences were statistically significant (P<0.05);the left ventricular ejection fraction (LVEF) in both groups was higher than before intervention,and LVEF in observation group was higher than that of the control group,the differences were statistically significant (P<0.05). Conclusion Active breathing cycle training assisted non-invasive ventilator can improve blood gas analysis,accelerate symptom relief,and enhance lung and heart function in patients with pulmonary heart disease and respiratory failure.
