Q

Forced expiration against a closed glottis produces increased intrathoracic pressure, increased central venous pressure, and decreased venous return know as ?

A

Valsalva maneuver - the resultant decrease in CO and blood pressure is sensed by baroreceptors, which reflexively increase HR and myocardial contractility through sympathetic stim.

Q

Once the glottis opens following a valsalva maneuver what happens

A

Venous return increases and so does the blood pressure, causing the baroreceptors to reflexively decrease the HR through the parasympathetic efferent pathway
