39
Q

what produces ECG strip

A

some pads
paddles
ECG leads w/defibrillator

40
Q

ECG lead advantage

A

more accurate ECG tracing
more reliable R wave sensing

41
Q

when is reliable R wave sensing required

A

pacing
sync cardioversion

42
Q

when are ECG leads required

A

pacing
sync cardioversion

43
Q

are ECG leads needed for defibrillation

A

no

44
Q

standard pads disadvantages

A

less reliable R wave sensing
dont measure chest compression effectiveness

45
Q

compression sensor prompts

A

rate
depth
idle time
see thru CPR filter

46

  4. One Step Basic
51
Q

which Zoll pads have a CPR sensor

A

one step CPR
one step Complete

52
Q

One step CPR limitation

A

less effective R wave sensing
