Breathing CO2 test to predict which anxiety therapies won’t work
Part of Mental health clinical trials.
This study uses a controlled breathing test (inhaling CO2 or breathing faster) to see if it can predict whether exposure-based therapy will help your anxiety disorder. If you are in the right group, the results may help doctors choose more effective treatment earlier.
Summary written for real people, not researchers, by Clin2.
