This is interesting to me partly because I saw a mask used with kids with brain damage in the early 70's that was designed to increase CO2 in order to trigger greater lung expansion and opening of blood vessels in the brain.....
Asthma patients taught to habitually resist the urge to take deep breaths when experiencing symptoms were rewarded with fewer symptoms and healthier lung function, according to a new study from Southern Methodist University, Dallas.
The findings are from a large clinical trial funded with a grant from the National Institutes of Health's National Heart, Lung, and Blood Institute.
The results suggest asthma patients using behavioral therapy in conjunction with their daily asthma medicine can improve their lung health over the long-term, said principal investigators Thomas Ritz and Alicia E. Meuret, both SMU clinical psychologists.
Also, sufferers may potentially reduce their dependence on emergency medication, such as rescue inhalers, the researchers said.
