Abstract
Asthma is the most common chronic disease of the respiratory system and the third leading
cause of death worldwide. Hyperventilation is a major cause of hypoxemia in asthmatics,
resulting in developing habitual chronic hidden hyperventilation that can be controlled by
performing various breathing exercises like Buteyko, Diaphragmatic Breathing Exercise.
Aim: To evaluate the effect of Buteyko versus Diaphragmatic Breathing Exercises on
selected outcomes among patients with asthma. Quasi-experimental (pre/post) design was
used, a convenient sample of 60 adult patients divided randomly into Buteyko Breathing
Exercise group (BBE) and Diaphragmatic Breathing Exercise group (DBE); 30 patients
/group were enrolled in the current study. The study was carried out at a governmental
hospital of chest diseases in Cairo, Egypt. Four tools were used for data collection: Semi
structured interview Questionnaire, Pulmonary Physiological Parameters, London Chest
Activity of Daily Living (LCADL) and Insomnia Severity Index (ISI). Results: The mean
age among BBE & DBE study groups were 41±13 and 38±11.1years respectively. Further,
60% of BBE and 53.3% of DBE were female. No statistical significant difference among
both BBE & DBE study groups regarding pulmonary physiological parameters, functional
limitation (t=0.73, P=0.39) and insomnia severity (t= 5.1, p=0.16) at baseline preintervention, while a highly statistical significant difference was shown for pulmonary
physiological parameters, functional limitation (t=31.0, p=0.0001) and insomnia severity
(t=27.46, p=0.000) at the 5th day post intervention. Conclusion: Based on the current study
findings, Buteyko Breathing Exercise was more effective in improving Oxygen Saturation,
PEFR and insomnia severity than Diaphragmatic Breathing Exercise. Recommendation:
Buteyko Breathing Exercise should be added as a possible non- pharmacological nursing
intervention in managing asthma.
