Describe steps in VF Treated with CPR & AED
Activate EMS / Get AED
Check Pulse:
---If no pulse - Begin 30comp:2breaths
---If pulse give 1 breath every 5-6 seconds, recheck pulse every 2 minutes
Place AED
VF Tx w/CPR&AED - Pulsless: Shockable rhythm
Give 1 shock
Resume CPR for 2 minutes
VF Tx w/CPR&AED - Pulseless: Rhythm is not shockable
Resume CPR for 2 minutes
Check rhythm every 2 minutes
Continue until ALS providers take over
VF Tx w/CPR&AED: Intro - Pulse present
Activate EMS / Get AED
Check Pulse - present -> Give 1 breath every 5-6 seconds
Give 1 breath every 5-6 seconds
Recheck pulse every 2 minutes
VF Tx w/CPR&AED: Protocol if pulseless
Activeate EMS / Get AED
Begin 30comp:2breaths
Place AED
For every minute that passes between collapse and defibrillation, the chance of survival from a witnessed VF sudden cardiac arrest declines by:

Define PEA
Organized rhythm without pulse
How much time should be taken for pulse check?
5-10 seconds
What is the role of routine fibrinolytic treatment in patients with cardiac arrest without known pulmonary embolus?
