Cardiac Arrest Flashcards
What is the rate of performing chest compressions?
80-100
NAVEL: ACLS Drugs Safe for Endotrachael Administration
Naloxone Atropine Vasopressin Epinephrine Lidocaine
Almost all episodes of sudden cardiac death initiate from:
A ventricular tachydysrythmia
Once pulseless VT or VF is identified, the patient should be immediately defibrillated using:
200J on a biphasic defibrillator or 360J on a monophasic defibrillator
How long should CPR be given between rhythm checks?
2 min (5 cycles)
What med to give for TdP?
Magnesium may be given for torsades de pointes.
Contraindications to Therapeutic Hypothermia include:
- -Severe cardiogenic shock (SBP<90 mmHg) despite fluids and inotropes
- -Cause of coma other than cardiac arrest (overdose, CVA)
- -Pregnancy
- -Known coagulopathy
- -Life-threatening arrhythmias
- -Initial temperature <30 C
- -Preexisting DNR status
- -Pediatric patients
The Inclusion Criteria for Therapeutic Hypothermia include:
- -Patients resuscitated after out-of-hospital witnessed arrest with VT/VF as initial rhythm
- -Resuscitation initiated by EMS within 5-15 minutes of arrest
- -No more than 60 minutes from collapse to return of spontaneous circulation (ROSC)
- -Persistent coma after ROSC
- -Adult age
- -Endotracheal intubation and mechanical ventilation
Vfib is primarily treated with:
Defibrillation
If 3 successive shocks and epinephrine have been given, the next step would be:
An antiarrhythmic agent, such as lidocaine or amiodarone
What is the treatment of choice for torsades de pointes?
Magnesium sulfate
If magnesium fails to break torsades, try what?
Overdrive pacing
What is the best response to PEA?
Treat the underlying etiology
Unstable VT is treated by:
A series of 3 stacked shocks, before medications are used
What is the optimal dosing of endotrachially administered drugs?
2-3x the standard (IV) dose
What is the standard ACLS dose of epinephrine?
1mg IC or IO of a 1:10,000 soln every 3-5 min
Standard treatments for asystole
Epinephrine, or
Atropine + vasopressin
Definition of Vfib
Totally disorganized depolarization and contraction of the ventricles. No discernible P, ST, T or QRS
Tx of complete AV block post-MI
Permanent pacing
T/F: The chin-lift maneuver risks spinal injury due to its employment of neck extension.
True
ST segment elevation is usually greater in lead III than lead II when:
Right ventricular infarction coexists with inferior AMI
Best way to diagnose a right ventricular infarction
Application of right-sided leads for EKG
Best mgmt of new onset RBBB
Pacemaker
What coronary vessel is usually he cause of MI in a pt with STE in V1, V2, V3?
LAD
