According to a study in 1993, for every minute a patient experiences VT, asystole, or PEA, the risk of
mortality increases by how much? - ANSWER 7-10%
CPR uses chest compressions to restore blood flow to important organs such as? - ANSWER The heart
and brain
4 types of arrhythmias discussed - ANSWER - VT
- PVT
- PEA
- Asystole
What is ventricular tachycardia? - ANSWER Wide QRS tachycardia characterized by 3 or more
consecutive PVC ~ 100-200 BPM
VT can lead to what? - ANSWER Ventricular fibrillation, systole, or cardiac arrest
Causes of VT - ANSWER - Ischemia
- Drug toxicity (digoxin)
- Electrolyte abnormalities
- Heart disease
What is sustained VT? - ANSWER - Lasts for > 30 seconds
- Symptomatic
- Can progress to life threatening incident
What is unsustained VT? - ANSWER - Brief and self-limited
, - Asymptomatic
How can V fib lead to death? - ANSWER No electric activity in the heart -> no cardiac output -> cardiac
arrest -> death
High quality CPR focuses on proper technique to ensure: - ANSWER - Adequate HR
- Depth of compression -> 100-200 beats/minute
- Full chest recoil after each compression (at least 2 inches)
- Avoidance of excessive ventilation
- Reduction in interruptions to increase compression fraction to 60% or above
Basic life support focuses on what? (Hint: CAB) - ANSWER - Compressions
- CAB = circulation, airway, and breathing
T or F: everyone should do a pulse check when performing BLS - ANSWER False - limit pulse checks
unless medical professional (check for 10 seconds and then start compressions)
How should a healthcare professional execute BLS? - ANSWER 30 compressions -->2 breaths until AED
arrives
How should a non-healthcare professional execute BLS? - ANSWER Compression only - NO breaths
Once AED arrives, what should be done? - ANSWER Check rhythm -> if the patient has a shockable
rhythm then give 1 shock (if non-shockable, do not shock) -> resume CPR immediately for 2 minutes
What should be administered during CPR? - ANSWER End tidal carbon dioxide (ETCO2)
Goal is > 20 mmHg
