I Got This, a cardiac review!
This is the formula for cardiac output
What is HR x SV?
Beta 1 receptors are located in this organ.
What is the Heart
Medication given in cardiac arrest/PEA
What is epinephrine?
This type of drug reduces peripheral resistance by dilating blood vessels and is us used as needed to treat acute chest pain due to narrowing coronary arteries.
What are vasodilators? Ex. nitroglycerin
This is a common side effect of nitroglycerin.
what is Hypotension, headache or syncope
Located in the right atrium and is known as the pacemaker of the heart.
What is the sinoatrial (SA) node?
These receptor sites are located in bronchial smooth muscle and vascular smooth muscle of skeletal blood vessels
What are beta 2 receptor sites.
These medications improve heart muscle contraction and are often used for heart failure.
What are Inotropic Agents?
This type of cardiac medication keeps HR low and decreases contractility.
What are beta-blockers? EX. esmolol
This is a common side effect of patients with hypovolemia receiving dopamine.
What is tachycardia? Must ensure that patient has adequate volume.
Relaxation phase of cardiac cycle, allows for filling of chambers.
What is diastole?
Medications that are contraindicated in patients with CHF, COPD, and asthma
What is beta blockers
This medication in low dose causes vasodilation in kidneys and mesentery, in moderate doses is a beta-1 (positive inotrope) and high dose will cause vasoconstriction to help treat hypotension.
What is dopamine?
This inodilator is indicated in the patient with heart failure and pulmonary congestion.
What is milrinone?
This is a potential side effect of epinephrine.
What is tachycardia and increased myocardial oxygen consumption?
This is the volume of blood ejected from the heart in one minute.
What is Cardiac Output?
Medications that stimulate the alpha -1 receptor sites.
What is alpha adrenergic/sympathomimetic?
These class of medications mimic the sympathetic nervous system and aim to restore blood pressure.
What are vasopressors?
These medications both dilate arteries and act as a positive inotrope.
What are inodilators? Ex: Dobutamine and Milrinone
This is a side effect of prolonged use of alpha blockers.
What is fluid retention?
Cardiac preload is determined by this variable (hint: preload is also called what?)
What is venous return?
These medications cause vasoconstriction results in increased blood pressure and preload.
What are alpha -1 agonists (aka adrenergic agonists) ex: epinephrine, norepinephrine, Neo-Synepherine
This positive inotrope can be used for for refractory bronchospasm.
What is isoproterenol?
This vasodilator causes direct smooth muscle relaxation and can be used to reduce afterload in heart failure
What is Nitroprusside?
Labetalol, used in severe hypertension, and is a beta blocker, it has this potential side effect and the HCP must be cautious with COPD patients.
What is bronchospasm?
