VasoPRESSors - PRESS on the vessels
Goes back to the heart
asoPRESSors - PRESS on the blood vessels,
Main Vasopressors
ncreasing blood pressure in order to squeeze
• Epinephrine
• Norepinephrine
xygen rich blood back to the CORE of the body
• Vasopressin o perfuse the vital organs (sort of like
• Dobutamine queezing a toothpaste bottle).
• Dopamine

• Squeezing down the blood vessels so blood is pushed back to the heart.
Alpha Agonist
• think AGonists ADD to the BP to increase it (example: vasopressors)
Alpha Antagonists
• are ANTI constriction - less constriction = less pressure to lower BP (example: clonidine)
Beta 1 = 1 Heart
Beta Agonists - think AGonists ADD - Faster heart rate. (example: Vasopressors)
• Positive Chronotropic (chronos = time) more beats per minute.
• Positive INOtropic = more FORCEFUL beats, which increased Cardiac OUTPUT (increased
blood coming OUT of the heart to perfuse the body)
Beta Antagonists - are ANTI heart, used to decrease the HR & BP (example: beta blockers) NORMAL
• Negative Chronotropic - Less Beats
HIGH
LOW
• Negative Inotropic - Less force
