The purpose of this study was to examine the effect of deep breathing exercise with Incentive Spirameter on the pulmonary ventilatory function of postoperative patients. This experiment was operative by quasiexperimental design which was compared
pre-experimental measures with post-experimental ones.
The subject of this study was 46 inpatients who were scheduled for elective upper abdominal surgery under the general anesthesia in P National University Hospital in Pusan and classified into experimental group(23 patients) and control group(23
patients) by using Incentive Spirometer or unusing one. The data were collected from November, 1, 1993, to December, 31, 1993. The effects of the deep breathing exercise on the pulmonary ventilatory function were compared between experimental
group
who
were received deep breathing exercise with Incentive Spirometer and control group who were received same method without Incentive Spirometer. The Forced Vital Capacity (FVC) and the First Second Forced Expiratory Volume(FEV1) were represented as
index
of the pulmonary ventilatory function and those were measured by Vitalograph Compact.
The collected data were analysed by SPSS/PC+(percentage, average, standard deviation, chi-square test, t-test, and ANOVA).
@ES The results were as follow:
@EN (1) The FVCs of the experimental group were significantly increased in course of time, 24, 48, 72 hours after surgery(F=3.530, P=0.035).
(2) The FVCs and FEV1s of the control group were significantly increased in course of time, 24, 48, 72 hours after surgery (FVCs: F=3.480, P=0.037, FEV1s: F=6.153. P=0.004).
(3) The FVC which was measured at 72 hours after surgery was significantly higher in the experimental group than in the control group(t=2.620, P=0.013).
(4) The FEV1s which were measured at 24 and 72 hours after surgery were significantly higher in the experimental group than in the control group(24hr.: t=2.530, P=0.017, 72hr. : t=2.540, P=0.016).
(5) Among general characteristics, sex was significant variable which influenced to effect of pulmonary venitlatory function.
In conclusion, this study showed that the deep breathing exercise with Incentive Spirometer was more effective to recover the pulmonary ventilatory function after surgery than the deep breathing exercise without Incentive Spirometer.
