What are some possible causes of -Vagal stimuli
Ventricular Tachycardia (VT)? -Hypovolemia
-Hypoxemia
-Acidosis
-Hyperkalemia or hypokalemia
-Hypoglycemia
-Hypocalcemia
-Hyperthermia or hypothermia
-Cardiac tamponade
-Tension pneumothorax
-Pulmonary or coronary emboli.
What is the appropriate immediate Immediate CPR at a rate of 100-120 per
treatment for Ventricular minute. If
Tachycardia the rhythm becomes shockable, shock with
(VT)? 120-
200J. For the 2nd shock, administer 1mg
of
epinephrine. For the 3rd shock, administer
1.5
mg/kg of lidocaine.
I'm assuming this is pulseless VT?
What are common medication- LAST, medication error or overdose, and
related causes of perioperative expected
cardiac arrest? effect of Adenosine.
