| Objective To explore the effect of active respiratory cycle on exercise tolerance in patients with chronic heart failure and the correlation between clinical effects and provide the basis for the cardiac rehabilitation of chronic heart failure.Methods 1?A convenient sampling method was used to study 100 patients with chronic heart failure who were hospitalized in the Department of Cardiology at a tertiary hospital in Shandong Province from June 2017 to December 2017.The patients were divided into an experimental group and a control group using a random number table method.50 cases in each group.2?During the hospitalization period,both the experimental group and the control group received routine chronic heart failure treatment and nursing care.On the basis of this,the experimental patients were instructed to perform active breathing cycle training 3 times a day,1 hour after the patient's early,middle and late dinner,every 10 minutes,7 days a week for the duration of the entire hospital stay.Patients in the control group were not given active breathing cycle technical training guidance.3?At admission,6-minute walking distance at discharge,resting heart rate before and after walking,systolic blood pressure,and oxygen saturation measurements were measured.Result The measurement data obtained in this study were described x±s;using SPSS17.0 software statistical analysis data,two independent sample t-tests were used between the two groups,paired t-tests were used before and after the intervention in the groups,and count data were analyzed using the ?2 test.P<0.05 was considered statistically significant.1.There was no difference in sociological data such as age,sex,height,weight,occupation,and educational level between the two groups of patients,as well as disease-related information such as heart function grading and disease course.During the intervention period,2 patients in the experimental group withdrew due to changes in condition,2 patients could not adhere to,2 patients with drug dose adjusted to withdraw;1 patient in the control group experienced worsening of the disease,2 patients with drug dose withdraw,3 patients with automatic withdrawal,and 88 subjects with complete experiment.The experimental group and the control group each had 44 cases.2.2?6 Minute Walk Distance At discharge,the 6-minute walking distance in the experimental group was significantly higher than that at admission(80.16±5.20)m,the difference was statistically significant(P<0.001),and the 6-minute walking distance in the control group was also increased(22.82±2.57)m compared with that at admission(P<0.001),the walking distance in the experimental group was longer(45.02±6.21)m than that in the control group.There was a statistically significant difference between the two groups(P<0.05).3.Resting Heart Rate At discharge,the oxygen saturation before and after the 6-minute walking test in the experimental group was higher than that at admission(P<0.001).When the two groups were compared,the oxygen saturation of the experimental group was significantly higher than that of the control group before and after the discharge from the 6-minute walk.The difference was statistically significant(P<0.05).4.systolic pressure At discharge,the resting heart rate before and after the 6-minute walking test in the experimental group was significantly lower than that at admission(8.59±2.00)beats/min and(7.90±2.96)beats/min(P<0.001).The control group was static before and after the 6-minute walk test.The heart rate was lower(8.18±2.15)beats/min and(7.57±3.10)beats/min(P<0.001)than on admission,but there was no significant difference between the two groups(P>0.05).5.oxygen saturation Within the group comparison,the systolic blood pressure of the experimental group before and after the 6-minute walk test was significantly lower(10.09±0.59)mmH and(9.91±0.96)mmHg than that at the time of discharge,and the difference was statistically significant(P<0.001).The systolic blood pressure before and after the minute walking test decreased(7.48±4.63)mmHg and(7.52±4.25)mmHg,respectively(P<0.001),but there was no significant difference between the two groups(P>0.05).Conclusion 1.Active respiratory cycle technology can effectively increase the 6-minute walking distance and increase blood oxygen saturation in patients with chronic heart failure,which can reduce resting heart rate and systolic blood pressure and improve exercise tolerance of patients.2.Active respiratory cycle technology can be used as an effective,simple and easy-to-use breathing training method to provide adjuvant therapy for cardiac rehabilitation in patients with chronic heart failure. |
