Buteyko breathing techniques in asthma: a blinded randomised controlled trial

Area of Science:

• Respiratory Medicine
• Pulmonology
• Integrative Health

Background:

• Asthma management often involves medication, but complementary techniques are explored.
• Hyperventilation is common in asthma patients.
• Buteyko breathing techniques (BBT) aim to correct dysfunctional breathing patterns.

Purpose of the Study:

• To investigate the efficacy of Buteyko breathing techniques (BBT) in managing asthma.
• To assess the impact of BBT on medication use, respiratory function, and quality of life in asthma patients.

Main Methods:

• A prospective, blinded, randomized study was conducted with 39 adult asthma patients.
• Participants were assigned to either BBT or control classes.
• Outcomes measured included medication use, peak expiratory flow (PEF), forced expiratory volume (FEV1), end-tidal CO2 (ETCO2), minute volume (MV), and quality of life (QOL).

Main Results:

• The BBT group showed a significant reduction in beta-2-agonist use compared to the control group (P=0.002).
• A trend towards reduced inhaled corticosteroid use was observed in the BBT group (P=0.06).
• The BBT group demonstrated a significant decrease in resting minute volume (P=0.004) and a trend towards improved QOL scores (P=0.09), without changes in PEF or FEV1.

Conclusions:

• Buteyko breathing techniques (BBT) effectively reduce hyperventilation and beta-2-agonist reliance in asthma patients.
• BBT may lead to reduced inhaled corticosteroid use and improved quality of life.
• These benefits were observed without significant changes in objective measures of airway caliber.
