Abstract

|
The purpose of this study was to examine the effects of deep breathing exercises using phonation on the pulmonary ventilatory function, dyspnea, and duration of chest tube insertion in patients with pneumothorax.
This experiment was operated by quasi-experimental design which was compared pre-experimental measures with post-experimental ones. The data were collected from August, 1, 1999 to October, 30, 1999. The subject of this study was 19 pneumothorax inpatients who were inserted chest tube in K hospital in Kwangju and classified into the experimental group(9 patients) and control group(10 patients). The experimental group received deep breathing exercises using phonation, and the control group didn’t receive that intervention.
The deep breathing exercise using phonation was performed 5 days on each patient of all experiment groups.
The effects of the deep breathing exercise using phonation on the pulmonary ventilatory function, dyspnea, and duration of chest tube insertion were compared between experimental group and control group. In order to measure the pulmonary ventilatory function, peak expiratory flow rate(PEFR) of each patient were measured by Mini-Wright Peak flow meter. And in order to measure dyspnea symptom, visual analog scale were used.
The collected data were analyzed by SPSS/PC+(percentage, average, standard deviation, chi-square test, t-test, paired t-test, and repeated ANOVA).
The results were as follows :
On comparing of the experimental group and the control group, the PEFR(t=.337, p=.576), dyspnea(t=.337, p=.576), and duration of chest tube insertion(t=1.755, p=.622) were not significantly different. But, the PEFR of the experimental group were significantly increased in course of day, 1, 5 days after receiving deep breathing exercise using phonation. The dyspnea which was measured at 1, 4 days after receiving deep breathing exercise using phonation was significantly lower in the experimental group.
Although a statistical significancy was not established, the deep breathing exercise using phonation was effective to recover the pulmonary reexpansion and pulmonary ventilatory function, so I suggest follow-up study in various patient group.
