WebCardiovascular responses to OSA can be explained in part by the diving reflex, a reflex response to prolonged breath hold, during which simultaneous increase in parasympathetic activity to the heart and sympathetic activity to the periphery lead to concomitant bradycardia as well as increased peripheral arterial resistance [8].These together aim at decreasing … WebJan 7, 2024 · Fig 1 – A sphygmomanometer and stethoscope being used to measure blood pressure. Mean arterial blood pressure = cardiac output x total peripheral resistance. Therefore, these are factors that can affect blood pressure. Cardiac output – the higher the cardiac output, the higher the volume of blood in the vessels.

"WebThe pupillary light reflex ( Figure 16.3.1) begins when light hits the retina and causes a signal to travel along the optic nerve. This is visual sensation, because the afferent branch of this reflex is simply sharing the special sense pathway. Bright light hitting the retina leads to the parasympathetic response, through the oculomotor nerve ... " - Cardiovascular reflexes are controlled by
