Comparative Study of Flutter Device and Active Cycle of Breathing Technique in Airway Clearance in Subjects with Chronic Obstructive Pulmonary Disease
Keywords:COPD- Chronic Obstructive Pulmonary Disease, PEFR- peak expiratory flow rate, FEV1 / FVC- Ratio of forced expiratory volume in one second to Forced Vital Capacity, ACBT- Active Cycle of Breathing Technique.
Background and Objectives: Chronic obstructive pulmonary disease is a disorder characterized by presence
of air flow obstruction that is generally progressive, may be accompanied by airway hyperactivity and
maybe partially reversible. COPD comprises major pathological changes. Conventional airway clearance
techniques form the main stay of the routine Pulmonary Rehabilitation of subjects with chronic obstructive
pulmonary disease. The procedure of Active Cycle of Breathing Technique causes an increase in lung volume
which allows air to flow via collateral channels and may assist in mobilizing the secretions which but
incorporating newer techniques that are effective, comfortable and can be independently performed by the
subject without assistance help motivate the subjects to participate actively in their own health care. A device
is proposed to have good efficacy, reliability and provides relief of the symptoms in a better way than the
manual therapy in a way by excluding the bias and thus can be used as an alternative to it, so proves efficient
to it. This study incorporates a device called ‘THE FLUTTER DEVICE’ which aids in mucus clearance in
subjects with COPD effectively. Materials and Methodology: The Study participants were thirty subjects
aged 35 to 45yrs with chronic obstructive pulmonary disease. After two weeks of ACBT and Flutter therapy
with routine Physiotherapy each patient was told to record their VAS score for breathlessness on Visual
Analogue Scale for breathlessness, the patient’s peak expiratory flow rate was then checked with the peak
flow meter and FEV1 /FVC percentage was also obtained from the patient’s Pulmonary Function Test reports.
Results: Data was analyzed by statistical means, standard deviation and students t- test and the results
showed significant changes in terms of the VAS score for breathlessness, PEFR, FEV1 /FVC percentage of
PFT. Conclusion: It can be concluded that application of flutter therapy for airway clearance to patients
with Chronic obstructive pulmonary disease decreased the breathlessness drastically and increased the peak
expiratory flow rate and FEV1 /FVC percentage than the application of ACBT.
