Abstract
Objective: To determine the effect of blowing balloons on pulmonary function tests and perceived level of
stress in medical students.
Study Design: Pretest-posttest quasi-experimental study.
Place and Duration of Study: This study was conducted at Department of Physiology, Islamic International
st st Medical College from 1 April 2016 to 31 May 2016.
Materials and Methods: Sixty students of Islamic International Medical College participated in the study after
fulfilling the DASS (Depression Anxiety Stress Scale) Questionnaire Performa. Pulmonary function tests of the
participants were measured according to the standard guidelines published by American Thoracic Society. This
was recorded by using Power lab and the data was then analyzed by using software, Lab chart 8 pro. The
participants were then subjected to a supervised blowing balloon exercise using commercially available
balloons. After completion of exercise, pulmonary function tests of the participants and the DASS
Questionnaire was filled again by the participants.
Results:After blowing balloon exercise DASS Score of the participants was reduced from 21.87 + 2.01 to 13.41 +
4.29 (p < 0.001). Tidal volume was increased from 517.72 + 48.57 ml to 638.65 + 86.02ml (p < 0.001), Vital
capacity was increased from 3.51 + 0.56 L to 4.83 + 0.77 L (p < 0.001) and the ratio of Forced Expiratory Volume
in one second to the Forced vital capacity was improved from 89.36 + 4.54 % to 92.66 + 4.27 % (p < 0.001) after
blowing balloon exercise.
Conclusion: Blowing balloon exercise is an effective way of improving pulmonary function tests and alleviating
stress levels in medical students.
