[A study on the effect of Dan Jeon breathing method to reduce blood pressure of the client with essential hypertension].

The purpose of this study is to evaluate the effectiveness of the Dan Jeon Breathing method and to suggest that the method is an effective nursing intervention to reduce the blood pressure. The Dan Jeon breathing method is composed of thirty-minute program including Dan Jeon Breathing, a kind of abdominal-deep breathing, free gymnastics, mental concentration, physical strength exercise, and suggestion. The Quasi-experimental design was used in this study. In order to evaluate the devised the Dan Jeon breathing method, the non-synchronized research method with non-equivalent control group was employed. The results of this study can be summarized as follows; 1. The blood pressure of the Dan Jeon breathing method training group was reduced as time goes by. When the training was finished, the systolic blood pressure was lower than the baseline blood pressure by 15.80 mmHg (Y = -1.11X + 147.78, P = .0001, R2 = 0.89), and the diastolic blood pressure was lower than the baseline blood pressure by 10.91 mmHg (Y = -0.85X + 98.9, P = .0001, R2 = 0.96). 2. The score of perceived stress of the Dan Jeon breathing method training group after training was lower than that of other groups (F = 2.51, P = .09). 3. The serum cortisol level of the Dan Jeon breathing method training group was reduced as compared with that of there groups (F = 3.21, P = .05). But aldosterone level of the Dan Jeon breathing method training group did not show any change. The result proved that the Dan Jeon breathing method was an effective behavioral therapy to reduce blood pressure of the client with the essential hypertension from this study. The Dan Jeon breathing method might be an effective nursing intervention device to protect the ego structure of the clients, to promote their well-being and to reconstruct them by setting mind and body at ease. The Dan Jeon breathing method can be used in clinic as well as in community as an independent nursing intervention. The Dan Jeon breathing method program might be considered to make a great contribution to adult care.
