BLS

Question 1

Adequate compression depth and strategy

Answer 1

At least 2 inches with shoulders used as a fulcrum over chest to use bodyweight to compress (step stool)

Question 2

Chest compression rate and strategy

Answer 2

• 100-120 bpm
• Complete chest recoil
• Minimize interruptions (including pauses to deliver ventilations

Question 3

What happens when chest compressions are interrupted?

Answer 3

Coronary perfusion pressure decreases dramatically and remains low until compressions are resumed

Question 4

What is required to reach adequate coronary perfusion pressure to get ROSC?

Answer 4

Several compressions are required to “build up” to the pressure required

Question 5

How long should interruptions in chest compressions be?

Answer 5

10 seconds or less

Question 6

Ventilation strategy

Answer 6

Avoid excessive ventilation

Question 7

How often should compressors be switched?

Answer 7

Every 2 minutes

Question 8

CPR compression to ventilation ratio

Answer 8

30:2

Question 9

Walk through 2 person CPR

Answer 9

1. Scene is safe
   
   2. Are you ok? Tap on them
   3. Call for help-Ask for defib
   4. Check for carotid pulse
      a. No pulse and/or not breathing
   5. Begin CPR Alone
      a. 30 Compressions: 2 Ventilations
   6. Help Arrives with defib
      a. Partner begins CPR
      b. I attach defib (attach pads to chest and plug pads into defib): “Analyzing rhythm. Do not touch patient.”
      c. CPR stops

Defib says “Shock Needed”
• Defib will charge: says “charging”
○ Continue not to touch the patient
○ Defib will say “Stay clear of patient. Deliver shock now.”
• I say: “Clear” and press the shock button
○ Defib says: “ Shock Delivered”
• Continue CPR
