100-120 compressions/min

9

From RECOVER, in nonintubated patients or single-rescuer CPR, what C:V ratio is recommended?

30:2

10

From RECOVER, recommended ventilation rate and tidal volume?

10 bpm and 10 ml/kg

11

From RECOVER, CPR should be performed in cycles of how many minutes?

2

12

From RECOVER, what is the low dose of epi? High dose? How often?

0.01 mg/kg (low), 0.1 mg/kg (high), and q 3-5min

13

4-6 J/kg (mono), 2-4 J/kg (bi)

15

From RECOVER, immediate defibrillation is recommended in cases of CPA due to VF of duration of how many minutes or less?

4 minutes or less

16

From RECOVER, T/F: immediate defibrillation may be considered if VF is diagnosed during a rhythm check b/w cycles of CPR

TRUE

17

From RECOVER, T/F: 2-minute cycle of CPR should PREcede defibrillation in cases of CPA due to VF of known or suspected duration of greater than 4 minutes.

TRUE

18

From RECOVER, which drug can be considered in cases of pulseless VT/VF resistant to defibrillation?

amiodarone

19

From RECOVER, what class is amiodarone? (Vaughan Williams classification)

Class III

20

From RECOVER, what is the MOA of amiodarone?

Classified as class III (potassium channel blocker), but also has Class I, II, and IV activity!

21

From RECOVER, what is the SECOND choice drug for pulseless VT/VF resistant to defibrillation?

Lidocaine

22

MgSO4 may be considered for which arrhythmia?

Torsades de pointes

23

MOA of impedance threshold device?

more negative intrathoracic pressure = more venous return = more cardiac output
