Why the study?
Does facial cooling alter peripheral chemoreflex mechanisms and cardiac vagal activation in normal humans?
Does facial cooling alter peripheral chemoreflex mechanisms and cardiac vagal activation in normal humans?
Facial cooling enhances peripheral chemoreflex mechanisms and cardiac vagal activation in normal humans, promoting bradycardia during apnea.
Facial cooling effects on chemoreflex and vagal tone remain untested in patients; leaves open relevance to apnea or arrhythmia management.
The larger ventilatory response to hypoxia suggests that facial cooling facilitates peripheral chemoreflex mechanisms in normal humans. Moreover, simultaneous diving reflex and peripheral chemoreflex activation enhances cardiac vagal activation, and favours further bradycardia upon cessation of breathing.
