Heart Code BLS

What ratio for compressions to breaths should be used for 1-rescuer infant CPR?

30 compressions to 2 breaths

How do you perform chest compressions when providing high-quality CPR to a child victim?

By compressing the chest at least one third the depth of the chest, about 2 inches (5 cm)

"The team functions smoothly when all team members know their positions, functions, and tasks during a resuscitation attempt." Match this statement with the most appropriate element of team dynamics listed.

Clear roles and responsibilities

While performing high-quality CPR on an adult, what action should you ensure is being accomplished?

Compressing to a depth of at least 2 inches

A 53-year-old woman collapses while gardening. She is unresponsive, is not breathing, and does not have a pulse. A neighbor, who is an emergency medical technician, rushes to her with an AED. After the AED pads are attached to the victim's bare chest, the AED detects ventricular fibrillation. What is the next step when using an AED?

Follow the AED prompts

An 8-month-old infant is eating and suddenly begins to cough. The infant is unable to make any noise shortly after. You pick up the infant and shout for help. You have determined that the infant is responsive and choking with a severe airway obstruction. How do you relieve the airway obstruction?

Give sets of 5 back slaps and 5 chest thrusts

Why is defibrillation important?

It can restore a regular cardiac rhythm

Rapid defibrillation is a link in the adult Chain of Survival. Why is this important to survival?

It eliminates the abnormal heart rhythm

How can rescuers ensure that they are providing effective breaths when using a bag-mask device?

Observing the chest rise with breaths

What is a consideration when you are using an AED?

On a hairy chest, the pads may not stick and may fail to deliver a shock

An 8-month-old infant is eating and suddenly begins to cough. The infant is unable to make any noise shortly after. You pick up the infant and shout for help. Which action do you perform to relieve choking in an unresponsive infant?

Perform CPR, and look in the mouth for the obstructing object

What should you do if you need to use an AED on someone who has been submerged in water?

Pull the victim out of the water, and wipe the chest

A victim with a foreign-body airway obstruction becomes unresponsive. What is your first course of action?

Start CPR, beginning with chest compressions

A 67-year-old man is found unresponsive, not breathing, and without a pulse. You and a second rescuer begin performing high-quality CPR. You notice the person giving chest compressions is not allowing for complete chest recoil. What is your next course of action?

Tell the compressor you notice decreased chest recoil

Why is allowing complete chest recoil important when performing high-quality CPR?

The heart will adequately refill between compressions

A 53-year-old woman collapses while gardening. She is unresponsive, is not breathing, and does not have a pulse. A neighbor, who is an emergency medical technician, rushes to her with an AED. When the AED arrives, what is the first step for using it?

Turn on the AED

A middle-aged man collapses. You and a second rescuer go to the victim and find that he is unresponsive, is not breathing, and does not have a pulse. You and another rescuer begin CPR. After a few cycles, you notice the chest compression rate is slowing. What should you say to offer constructive feedback?

"You need to compress at a rate of 100 to 120 per minute."

A 9-year-old child has suddenly collapsed. After confirming that the scene is safe, a single rescuer determines that the child is in cardiac arrest, shouts for nearby help, and activates the emergency response system. He immediately begins performing high-quality CPR. Two additional rescuers arrive to assist in the resuscitation attempt. What actions should occur next, to support a team-based resuscitation attempt?

2 rescuers alternate giving high-quality chest compressions

Which victim requires high-quality CPR?

A victim who is unresponsive with no normal breathing and no pulse

A 9-year-old child has suddenly collapsed. After confirming that the scene is safe, a single rescuer determines that the child is in cardiac arrest, shouts for nearby help, and activates the emergency response system. He immediately begins performing high-quality CPR. Two additional rescuers arrive to assist in the resuscitation attempt. Two rescuers begin high-quality CPR while the third rescuer leaves to get the AED. What action supports 2-rescuer CPR?

Alternating the compressor role every 2 minutes C. Alternating giving rescue breaths every 3 cycles

You witness someone suddenly collapse. The person is unresponsive, you hear gasping sounds, and there is no pulse. What should you do next?

Begin CPR; the gasps are not normal breathing

When performing CPR on an unresponsive choking victim, what modification should you incorporate?

Each time you open the airway, look for the obstructing object

"Members of the team know their boundaries and ask for help before the resuscitation attempt worsens." Match this statement with the most appropriate element of team dynamics listed.

Knowing your limitations

A middle-aged man collapses. You and a second rescuer go to the victim and find that he is unresponsive, is not breathing, and does not have a pulse. Which action is most likely to positively impact this victim's survival?

Performing high-quality CPR

A 67-year-old man is found unresponsive, not breathing, and without a pulse. You and a second rescuer begin performing high-quality CPR. When should rescuers switch positions during CPR?

Switch rescuers about every 2 minutes
