Asystole Treatment Algorithm

1
Asystole Treatment Algorithm
Continue CPR Intubate at once ???????? ???????
EKG 2 Lead ??????

• causes
• Hypoxia
• Hyperkalemia
• Hypokalemia
• Preexisting acidosis
• Drug overdose

2
transcutaneous pacing (TCP) a
Epinephrine 1 mg IV push,b,c
repeat every 3-5 min
Atropine 1 mg IV, repeat every 3-5 min up to
a total of 0.03-0.04 mg/kg d , e
Consider termination of efforts1
3
Pulseless Electrical Activity (PEA)
Algorithm(Electromechanical Dissociation EMD)
Epinephrine 1 mg IV push,a,c repeat every 3-5
min
If absolute bradycardia (lt60 BPM) or relative
bradycardia, give atropine 1 mg IV Repeat every
3-5 min to a total of 0.03-0.04 mg/kgd

• Consider possible causes
• (Parenthneses possible therapies and
  treatments)
• - Hypovolemia (volume infusion)
• - Hypoxia (ventilation)
• - Cardiac tamponade (pericardiocentesis)
• - Tension pneumothorax (needle decompression)
• - Hypothermia
• - Massive pulmonary embolism
  
  (surgery,
  thrombolytics)
• - Drug overdoses such as tricyclics, digitalis,
  -blockers, calcium channel blockers
• - Hyperkalemiaa
• - Acidosisb
• - Massive acute myocardial infarction
• (go to ACLS 6)

5
Ventricular Fibrillation / Pulseless Ventricular
Tachycardia(VF/VT) Algorithm
ABCs Perform CPR until defibrillator
attacheda VF/VT present on defibrillator
Defibrillate up to 3 times if needed for
persistent VF/VT (200 J, 200-300 J, 360 J)???????
Biphasic ??????????????????
6
Continue CPR Intubate once Obtain IV access
Epinephrine 1 mg IV push,b,c repeat every 3-5
min Vasopressin 40 IU. IV single dose (Class Iib)
Defibrillate 360 J within 30-60 Sd
????? Antiarrhythmics. Amiodarone Lidocaine
MgSO4
Defibrillate 360 J ???
