vasopressor and inotropes vasopressors
causes vasoconstriction that increases 导致血管收缩增加
systemic vascular resistance so mean 全身血管阻力所以意味着
arterial pressure increases whereas 动脉压增加而
inotropes increase cardiac contractility inotropes 增加心肌收缩力
most of the drugs have both the effects 大多数药物都有这两种作用

vasopressors and inotropes acts via 血管加压剂和inotropes通过
receptors alpha 1 receptor in vascular 受体α1受体在血管中的作用
bed causes vasoconstriction and in heart 床会引起血管收缩和心脏病
it increases contraction without 它没有增加收缩
increase in heart rate beta 1 receptor 增加心脏速率测试1受体
in heart causes increase in cardiac 在心脏导致心脏增加
contractility and heart rate beta 2 收缩力和心率β2
receptor in vascular bed causes 血管床受体的原因
vasodilation dopamine receptors present 存在血管舒张多巴胺受体
in renal splanchnic coronary and 在肾脏内脏冠状动脉和肾脏
cerebral vascular beds causes 脑血管床的原因
vasodilation epinephrine has a strong 血管舒张肾上腺素有很强的作用
alpha 1 action at high doses strong beta 高剂量的 α1 作用强β
1 action and a moderate beta 2 action so 1动作和适度的beta 2动作如此
increases heart rate and cardiac 增加心率和心脏
contractility due to beta 1 action β1 作用引起的收缩性
decreases SVR due to beta 2 action but 由于β2作用而降低SVR但是
at higher doses due to alpha 1 action it 由于α1作用，它在更高的剂量下
increases SVR norepinephrine has strong 增加SVR去甲肾上腺素有很强的作用
alpha 1 and moderate beta 1 action it alpha 1和中度beta 1动作吧
has no beta 2 action so increases SVR 没有β2动作因此增加了SVR
heart rate and mean arterial pressure 心率和平均动脉压
phenylephrine has only strong alpha 1 去氧肾上腺素仅具有强α1
action so it causes increase in SVR and 因此它会导致SVR增加
mean arterial pressure with no change in 平均动脉压无变化
cardiac output dopamine has moderate 心输出量多巴胺有中度
alpha 1 action only at high dose beta 1 仅在高剂量β1时 α1作用
action increases as dose increases no 随着剂量增加，动作增加
beta 2 action and it has moderate action beta 2行动，它有适度的行动
on dopaminergic receptors even at low 多巴胺能受体即使在低水平
doses so at low dose it increases renal 因此，在低剂量时它会增加肾脏
perfusion via dopamine receptor and 多巴胺受体和多巴胺受体的灌注
increases heart rate by a beta 1 通过beta 1提高心率
receptor at moderate dose it increases 中等剂量的受体增加
SVR via alpha 1 receptor and increases SVR通过α1受体而增加
heart rate and contractility via beta 1 心率和收缩力通过beta 1
receptor 接收器
at high dose it increases SVR and mean 在高剂量时它会增加SVR和平均值
arterial pressure via alpha 1 receptor 通过α1受体的动脉压
dobutamine has weak or no alpha 1 action 多巴酚丁胺的作用很弱或没有α1作用
strong beta 1 action and moderate beta 2 强烈的beta 1动作和温和的beta 2
action so it increases heart rate and 行动所以它会增加心率和
decreases SVR 降低SVR
