Breath-holding and its breakpoint
TL;DR
Voluntary breath-holding has physiological limits
Research demonstrating limits of voluntary override in hybrid respiratory control - chemoreceptor feedback eventually forces involuntary breathing, illustrating hierarchical priority in hybrid systems.
Key Findings from Parkes (2006)
- Voluntary breath-holding has physiological limits
- Rising CO2 triggers involuntary breathing
- Distributed chemoreceptor feedback overrides voluntary control
- System prevents fatal self-override
