Introduction: Chronic Obstructive pulmonary disease (COPD) is characterized by airflow obstruction with breathing-related symptoms such as chronic cough, exertion dyspnoea, expectoration, and wheeze [1]. The Buteyko concept is a system of breathing exercises originally devised in the 1950s by Professor Konstantin Buteyko, a Russian physician and ac...

There was significant improvement in Pulmonary Function Test in COPD patients through Buteyko breathing exercise than Pursed Lip Breathing for 4 weeks in patients with COPD.There was significant improvement in Dyspnoea post Buteyko breathing exercise than pursed lip breathing for 4 weeks in patients with COPD. 12 A study conduct by Geddes EL et al. 2008 states that inspiratory muscle training to determine its effect on inspiratory muscle strength and endurance, exercise capacity, dyspnoea and quality of life for adults with chronic obstructive pulmonary disease. Results indicate that targeted resistive or threshold IMT was associated with significant improvements in some outcomes of inspiratory muscle strength and endurance (Inspiratory Threshold Loading), exercise capacity (Borg Scale for Respiratory Effort (modified Borg scale), Work Rate maximum (Watts)), and dyspnea (Transition Dyspnea Index), whereas IMT without a target or not using threshold training did not show improvement in these variables. ...
Introduction: Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality
worldwide. COPD is characterized by persistent expiratory flow limitation which is usually progressive. Dyspnea
is the most prominent exercise-limiting symptom of the disease, which leads to chronic avoidance of physical
activities.1
Inspiratory muscle training (IMT) has frequently been applied in patients with chronic obstructive pulmonary
disease (COPD) to improve inspiratory muscle function, exertional dyspnea, and exercise tolerance. Results of the
latest meta-analysis indicate that IMT as a stand-alone treatment yields clinically meaningful improvements in
inspiratory muscle strength and endurance, functional exercise capacity, dyspnea, and quality of life.8
Aim of Study: “To Compare the Effectiveness of Inspiratory Muscle Training and Threshold device (IMT) in
patients with Chronic Obstructive Pulmonary Disease”
Methodology: This is a comparativestudy and study done in OPD and IPD of SMIH Patel Nagar, Dehradun
(UK). A total of 30 subjects of either gender, diagnosed to have mild, moderate and severe COPD were included in
thestudy and randomly divided into 2 groups 15 in each i.e. (Group A) Inspiratory muscle training and Threshold
group (IMT) (group B).
Limitation of Study: The study is conducted for a short duration and study shows only immediate effects and not
the long term effects.
Proper follow up is not done with the patients due to COVID-19 Pandemic.
Total size of population group studied was small.
In this study, the effects of extrinsic factors such as administration of drugs like Bronchodilators, Beta blockers,
Corticosteroids, etc. and intakes of caffeine in the diet are not considered while including patients in the study.
Future Research: Study can be done on largerpopulation. Further study can be done to check the combined effects
of Inspiratoy muscle training and Threshold Devices. The exact mechanism behind the reduction of dyspnea
following Inspiratory muscle training and the relationship between the reduction of dyspnea and Threshold Device
can be studied in more detail. The duration of study can be increased.
Conclusion: Analyzing and comparing both groups pre and post data, although both group shows significant
differences with in the groups and between the groups but group A (Exercise Group) shows slightly more significant
improvement in both outcome measures.
Therefore, results suggest that after 4 week of Inspiratory muscle training and threshold device(IMT), both group
shows improvement in Dyspnea but Inspiratory muscle training shows more improvement in Dyspnea in COPD
patients.

Chronic obstructive pulmonary disease is still a threat to the world community COPD will have a negative impact on the health of sufferers. The purpose of this study was to analyze the effect of buteyko breathing on expiratory peak currents in COPD patients. This research is a type of quantitative research with a pre-experimental design through a one group pre-post test design approach. The sample in this study was 58 COPD patients who fit the inclusion criteria. The tools used for data collection are peak flow meters to measure expiratory peak flows and SPO for buteyko breathing exercises. The results of the study included the average value of the peak expiratory current before giving buteyko breathing was 158.34 L / minute with a standard deviation of 69.1899. The average peak expiratory current after buteyko breathing is 144.42 L/min with a standard deviation of 16.21961. The difference in the increase in expiratory peak current before buteyko breathing and after buteyko breathing was 24.91. The paired t test results are p value of 0.001, it was found that there was a significant effect of buteyko breathing on the increase in expiratory peak current of COPD patients. Structured breathing exercises from buteyko exercise have the potential to increase lung capacity, allow for more efficient oxygen uptake, help achieve deeper and more efficient breathing, potentially affect oxygen saturation levels.
