Which vagal maneuvers is best on an infant?

The best vagal maneuver for an infant is gentle stimulation of the infant’s face, particularly by rubbing the forehead or applying gentle pressure to the eyes. This can help to stimulate the vagus nerve and potentially alleviate issues like bradycardia or certain types of arrhythmias. Additionally, the “diving reflex” can be triggered by immersing the infant's face in water for a brief moment, but this should only be done under professional supervision. Always consult a healthcare provider for guidance in managing an infant's medical concerns.
