b is CO2 reactivity, V1 is blood flow velocity of P1CO2, and PETCO2 is end-tidal CO2 partial pressure. To measure and control for variables such as blood pressure, pulse rate, and expiratory CO2 concentration, various modules of the Cardiocap S/5 collector (Datex-Ohmeda, Helsinki, Finland...
We present quantitative measures of brain volume changes using 3D high-resolution MRI, microstructural changes using DTI, baseline CBF, and finally, blood oxygenation level dependent (BOLD) signal changes in response to precise end-tidal (i.e. end exhaled) partial pressure of CO2 (PetCO2) to ...
Another breathing retraining attempt is described in the article “Behavioral control of intractable idiopathic seizures: I. Self-regulation of end-tidal carbon dioxide” published in Psychosomatic Medicine (Fried et al, 1984). This time 18 patients were able to partially normalize their breathing patt...
