Q

Standard Pads:

  • Location options
  • Disadvantages
  • ECG needs
A

Location pairings: Anterior/posterior or Right anterior/Apex-lateral.
Disadvantages:
1. Lower quality r-waves than ECG leads
2. No compression detector.
ECG Needs: Need separate ECG leads for pacing/cardioversion.

Q

Pads with a Compression Sensor 4-way feedback

A
  1. See thru CPR rhythm during compressions
  2. Prompts you to go faster if rate<80
  3. Prompts if idle time too long
  4. Depth detector. Hexagon on monitor fills with depth of compressions. (2-2.4)

Q

CPR pad limitation

Should we get ECG leads?

A

less effective R-wave.

Yes use ECG if we need to pace/cardiovert.

Q

How to use One Step CPR pads for atrial cardioversion.

A

invert left anterior pad and place on right anterior so compression sensor still aligns with sternum.

Q

One Step Pacing Pad:

  • Placement
  • ECG leads needed?
A
  • Posterior/ Left Anterior

- No additional ECG leads needed as long as anterior pad is left of sternum.

Q

Can One Step Pacing pad be used for atrial cardioversion?

A

Yes, invert the anterior pad and put it on the right upper but R-wave is useless so Yo DO NEED ECG cable.

Q

What 4 things are available with a One Step COMPLETE pad?

A

CPR compression sensing
Defibrillation
Cardioversion w/out separate ECG cable
Pacing w/out separate ECG cable

17
Q

Can complete pad be used on R-anterior? Any lost capabilities?

A

Yes, like others, just invert the Left anterior pad and place it on R anterior. In order to detect R-waves, need separate ECG cable.
Can still sense compressions and defibrillate.

18
Q

Placement of One Step Basic Pad?

A

Posterior/L-anterior

Needs separate ECG cable.

19
Q

When do I plug in the One Step ECG adaptor cable to back of defibrillator?

A

Only plug in the One Step ECG adapter if monitoring ECG thru One Step Cable.

20
Q

When must One Step ECG adapter be unplugged?

A

When using standard ECG leads. They must be plugged into the back of the monitor.

21
Q

Which pads have a built in 3 lead ECG?

A

One Step Complete and One Step Pacing Pads.

22
Q

Which One Step Pads DO NOT have Built in 3-lead ECG?

A

One Step Basic and CPR

23
Q

Internal Handles are used for which area of the body?

A

Open hearts when they fibrillate coming off pump.

24
Q

What is the energy dose for internal handles on open heart?

A

10-20 Joules

25
Q

CPR box on screen shows adequacy of chest compressions thru these 3 qualities:

A
  1. Rate prompt
  2. Depth Prompt
  3. Idle Time
26
Q

Manual Defibrillator Controls (4)

A

Analyze
Energy Select
Charge
Shock

27
Q

The bottom screen will always show an energy to be delivered UNLESS…

A

The Control knob is set to Monitor

28
Q

Battery Indicator Lights

A

Green=good
Yellow=charging
Alt green/yellow=problems

29
Q

Recorder button does what?

A

prints out ECG strip

30
Q

How to Defibrillate (5 steps)

A
  1. Place Pad
  2. Turn know to Defib
  3. Select Energy (200J)
  4. Charge
  5. Shock
31
Q

If Defibrillating with paddles, name 3 functions performed on paddles themselves:

A
  1. Choose energy
  2. Charge
  3. Shock
32
Q

How to perform Synchronized Cardioversion: 6 steps

A
  1. Place pads: posterior/L-ant for Vent. Posterior/R-ant for atrial.
  2. Turn knob to defib
  3. Press “sync” button before each shock attempt. Markers appear over R waves.
  4. Select energy: 75-120J
  5. Hit charge button
  6. Hit Shock button
33
Q

How to perform Transcutaneous Pacing: 5 steps

A
  1. Place Pads: Posterior/L-anterior
  2. Turn know to Pace
  3. Select HR w/Rate knob.
  4. Change energy with mA knob.
  5. Set maintenance threshold 10% above pacing threshold.
    Ex) if capture is at 50mA, set maint. to 55mA
34
Q

What does 4:1 button do?

A

It suppresses 3 of 4 pacer impulses so I can see intrinsic rhythm to determine if bradycardia remains.
