ok, so imagine walking down the street and you meet something frightening that you need to run away from. think of what will be going on in your body as you run away from such that frightening situation ... think of it from your head to your feet.
Eye - dilated so you can see clearly and run
Lungs - vessels/airway adequately dilated to allow for good ventilation
Heart - pumps strongly and releases needed blood to all major organs to aid in your flee
Git - this is definitely not the tym to move bowels
bladder - this is definitely not the time to pee
etc etc.
these responses are typical effects of most adrenergics, cardiac glycosides and pos ionotropics.
so looking at this you can appreciate why some meds that are good for respiratory conditions like asthma cannot be given to a patient with a cardiac condition. eg; theophylline
think of the vagal nerve.....it helps reduce heart rate, but when u r running the git is hypoactive so definitely the vagal nerve is not affecting the heart rate here.
and oh remember the popular digoxin too; its a cardiac glycoside that increases myocardial contraction and at the same time reduces the Heart rate. interesting!!! its side effect includes nausea, vomitting, halo around eyes.
normal level: 0.5--1.0ng/mL
finally, normal therapeutic levels for PACT: 10-20mcg/ml
