Discussion

Observational analysis mapped regional hemodynamic and deoxygenation responses in subjects, indicating varied dynamics during breath-holds.

Deoxygenation responses change significantly across repeated breath-holds, highlighting important timing variations.
During initial breath-holds, cerebral cO2 Hb dropped substantially, yet subsequent attempts showed diminished responses.
A triphasic response in peripheral tissue (de)oxygenation was observed, with notable differences in the first attempt.
The study assessed 15 volunteers, revealing crucial insights about cardiovascular stability and gas exchange across trials.

Elia et al. (2025) studied this question.
