BLS

Question 1

First step to BLS

Answer 1

Verify scene safety

Question 2

After verifying scene safety, what are the initial steps for BLS?

Answer 2

• Check for responsiveness
• Shout for nearby help
• Activate emergency response system (e.g. call 911)
• Get AED and emergency equipment
• Evaluate breathing/pulse

Question 3

How long should you check for a pulse before starting CPR?

Answer 3

No more than 10 seconds

Question 4

What should you do if you feel a pulse, but there is no breathing (or only gasping)?

Answer 4

• Provide rescue breathing (1 breath every 6 seconds)
• Check pulse every 2 min
• Check pupils (administer naloxone if pinpoint)

Question 5

How frequent should rescue breaths be administered (when there is still a pulse)?

Answer 5

1 breath every 6 seconds

Question 6

When should the AED be applied to the pt?

Answer 6

As soon as it is available (stop compressions to administer shock if needed)

Question 7

What is compression/breath frequency in CPR?

Answer 7

30 compressions and 2 breaths

Note: Pause CPR every 2 min to allow for a rhythm check (and possible shock).

Question 8

What is the appropriate rate of compressions for infants?

Answer 8

100-120 compressions per minute (same as adults)

Question 9

How deep should chest compressions be on an infant?

Answer 9

1.5 inches (4 cm)

Note: This is less than the 2 inches for children/adults.

Question 10

What is the compression:ventilation ratio for infants and children?

Answer 10

15:2 (if 2 or more rescuers)

30:2 (if 1 rescuer)

Question 11

Where should you place your hands to perform compressions on a child?

Answer 11

Lower half of sternum

Question 12

Rate of rescue breaths for child with abnormal breathing and a normal pulse

Answer 12

Every 2-3 seconds (20-30 breaths per minute)

Question 13

While administering rescue breaths, HR drops below 60 beats/min and you notice signs of poor perfusion…

Answer 13

Start CPR

Question 14

If you witness a child go into cardiac arrest, how does this change the single rescuer CPR algorithm?

Answer 14

You activate the emergency response system and retrieve the AED before beginning compressions

Note: If the cardiac arrest is unwitnessed, you perform 2 min of CPR prior to activating EMS and retrieving the AED (if still alone).

Question 15

What is the preferred method for a pulse check in an infant?

Answer 15

2-3 fingers on the inside of the upper arm (midway between the elbow and shoulder)
