Alpha Agonist • Think AGonists ADD to the ВР to increase it (example: vasopressors) Alpha Antagonists • Аге ANTI constriction - less coпstriction = less pressure to lower ВР (example: clonidine) Beta 1 = 1 Heart Beta Agonists - think AGonists ADD - Faster heart rate. (example: Vasopressors) • Positive Chronotropic (chroпos = time) more beats рег miпute. • Positive INOtropic = more FORCEFUL beats, which increased Cardiac OUTPUT (increased Ыооd comiпg OUT of the heart to perfuse the body) ii о1 Beta Antagonists - аге ANTI heart, used to decrease the HR & ВР (example: beta Ыockers) • Negative Chronotropic - Less Beats • Negative Inotropic - Less force Beta 2 = 2 Lungs Beta 2 Agonist • Think they ADD to the lungs - dilating both the vessels & broпchi - like а Ьig ballooп ог beach ball (example: Vasopressors & Albuterol) • Chrono • HJgh HR • 1notropic • С.О. 1heart 2 Lungs & Dllatfon Big Lungs &Vessels BIG Med!um Small BIG Med!um Small Med.
