Effect of Buteyko Breathing Technique on Haemodynamic Parameters and Functional Capacity in Subjects with Primary Hypertension
Keywords:Hypertension; Buteyko Breathing Technique; slow breathing.
The Buteyko Breathing Technique (BBT) has been found to be effective in the treatment of Asthma, Obstructive
Airway Disease and other diseases. Its effect on Hypertension has not been studied.
Aim and Objectives: To study the effect of Buteyko Breathing technique for 4 weeks on Hemodynamic parameters
and functional capacity in subjects with primary hypertension.
Methodology: Parallel group study design in which 66 subjects from Hypertension OPD of Tertiary Health Care
Centre were enrolled after taking their consent and Institutional Ethical approval. The subjects were randomly
allocated to Control (N=33) (receiving standard treatment of care) and Experimental (N=33) (receiving Buteyko
and standard treatment of care). Standard treatment of care included medication and educational videos on
Hypertension, its complications and management. Buteyko Breathing Technique included supervised session of
30 minutes using a video once in a week for 4 weeks. Subjects were informed to perform these exercises at home
Results: The experimental group showed a significant reduction in SBP (p=0.00), DBP (p=0.00), Resting HR (p=0.00)
and a significant improvement in Control Pause (p=0.00) and 6MWD (p=0.00). There was a mean reduction in SBP
of 8.6 + 6.31 mmHg (95% CI, 10.84- 6.36 mmHg) and in DBP of 4.606 + 4.34 mmHg (95% CI, 6.14-3.06mmHg).
Conclusion: Buteyko Breathing Technique has a positive effect on Haemodynamic parameters and functional
capacity in subjects with Essential Hypertension.
