What is the depth of chest compressions in cpr?
How many compressions/min in cpr?
What is the new sequence of cpr for lay people?
C-A-B (focus on compressions)
What are the 4 main types of pulseless arrest?
- 1)pulseless v-tach
- 3)pulseless electrical activity
Which 2 forms of pulseless arrest are not shockable?
asystole and PEA
What is the first step in unconscious patient?
Get help (911) and get defibrillator (AED)
What is the first step in CPR if you are alone?
5 CPR cycles (2 min) then get help and defibrillator
In BLS, after 1 cycle of CPR done what is next step?
10 second pulse check
In BLS, what is the appropriate ratio of compressions to breaths?
What do you do during CPR when defibrillator arrives and rhythm found to be shockable?
Shock, then resume CPR (if not shockable, just continue CPR cycles with pulse checks each 2 minutes)
During CPR, what do you do if a pulse is felt?
Stop CPR, breath for patient only (1 breath every 5-6 secs)
What is the appropriate amount of energy to use to defibrillate?
360J for monophasic, 120-200 biphasic
What medicine is used to try and defibrillate heart and how often can it be given?
Epinephrine 1mg q3-5 minutes (40u vasopressin can be used for dose 1 or 2 of EPI)
Patient has v-fib, no pulse, has been shocked and given 1 dose of epi, still in v-fib with no pulse. What should be done next?
Shock and give amiodarone (or lidocaine)
What doses of amiodarone can be given in pulseless vtach/vfib?
300mg followed by 150mg
What dose of lidocaine can be used for pulseless vtach or vfib?
1-1.5mg/kg (max 3mg/kg)
