Does increased intrapulmonary pressure affect heart rate and arterial blood pressure in anesthetized dogs?
In anesthetized dogs, high pulmonary inflation pressure induces paradoxical bradycardia and prevents arterial pressure overshoot, likely due to reflex vagal activity and mechanical effects of muscle relaxation.
Kenji Hayashi (1969) studied this question.
