Receptors
The receptor responsible for vasoconstriction
What is alpha receptors?
What is cardiac output?
Normal: 4 - 8 L/min
What is cardiac output?
This vasopressor is the most commonly used medication to treat hypotension
What is levophed or norepinephrine?
This antihypertensive can be administered under the tongue or as a paste
What is nitro?
This receptor is located in the heart and effects heart rate and contractility
Normal: 800-1200 dynes sec/cm5
What is systemic vascular resistance?
This inotrope has beta 1 and beta 2 effects and is often used to treat heart failure and/or cardiogenic shock
What is doBUTamine?
This vasodilator is often remembered for decreasing blood pressure while causing a headache
What is nitroglycerin?
This receptor is located in the bronchial and vascular smooth muscles
What is beta 2 receptors?
The volume of blood ejected with each heartbeat or ventricular contraction
What is stroke volume?
The half-life of Milrinone
What is 4 to 6 hours?
What is neosynephrine?
This calcium channel blocker is used cautiously by CV surgeons because of its increased risk of shunting
What is cardene or nicardipine?
This receptor increases afterload by causing peripheral vasoconstriction and increasing blood pressure
What is alpha receptors?
Atrial systole decreases preload by what percent?
What is 20%?
The force and velocity with which ventricular ejection occurs
What is contractility? Also known as "the squeeze"
This vasopressor is a naturally occurring anti-diuretic hormone that increases preload and blood pressure
What is vasopressin?
This venodilator when given IV, works immediately and has a half-life of 1 to 4 minutes?
What is nitroglycerin?
What is beta 1 receptors?
The resistance to blood flow returning to the left ventricle
What is systemic vascular resistance?
Normal: 2 - 6 Hg
What is right atrial pressure? Also known as CVP
This vasopressor relaxes bronchial smooth muscle by stimulating beta 2 receptors and alpha/beta receptors in the sympathetic nervous system
What is epinephrine?
This antihypertensive inhibits calcium ion influx across cardiac and smooth muscle cells?
What is cardene?
