|
appropriate urinary output in ml/kg/hr
|
0.5 ml/kg/hr min
|
|
|
5 classes of shock and an example from each
|
hypovolemic shock ie hemorrhage
cardiogenic shock ie pump failure distributive shock ie anaphylaxis, intoxication, sepsis neurogenic shock- spinal cord injury obstructive shock- PE |
|
|
MABP = ?
|
MABP = DBP + 1/3 (SBP-DBP)
|
|
|
What is PEEP and how high should you start it?
|
Positive End Expiratory Pressure
Start PEEP at 3-5 cm H20 |
|
|
Your patients HR has stopped, in addiiton to CPR what 2 drugs would you give alternatively
|
atropine- anti muscarinic
epinephrine- non selective adrenergic agonist |
|
|
What is the cutoff for cardioversion in afib?
|
48 hrs.. if longer will need to anticoagulate first
|
|
|
When do patients require blood?
|
When their Hct falls below 20-24% or below 30% if they have CHF
|
|
|
Contrast B2 and B1 activation
|
B1 is in myocardium stimulation cause s increased contractility and cardiac output
B2 is in arterial and bronchial smooth muscle. Activation will relax bronchials and vasodilate arterioles |
|
|
Norepinephrine MOA and indication
|
primarily alpha 1 agonist and some low dose non selective B agonist activity. Increases SVR and HR used to treat septic shock
|
|
|
Dopamine MOA and indications
|
DA activates B receptor at low dose and both alpha and B at high doses. Rec. as agent of choice in pts with cardiogenic shock and low SBP
|
|
|
Dobutamine MOA
|
Dobutamine activates B receptors. it is a more potent cardiac stimulant then dopamine, increases CO and SVR with variable effect on MABP.
Causes pulmonary vasodilation |
|
|
Epi moa and indication for use
|
EPI is potent alpha and Beta agonist 500x more potent then dopamine or dobutamine. Increases myocardial O2 consumption. used for cardiac arrest, anaphylatic shock and life threatening bradycardia
