Q

What 4 things can increase Cardiac output?

A

Sympathetic nervous system activation and catecholamines include dopamine, epinephrine (adrenaline), and norepinephrine (noradrenaline).

Early infection cause you got massive Vaso dilation. Easy able to eject blood in sep

Q

What can decrease cardio output

A

Preload- dehydration or overload

After load - is clamped down

Contractility - if the HR is slow speed him up atropine or pacemaker
If to fast speed him up with adenosine
