• your heart rate while at rest.

• the number of times your heart beats per minute.

• the highest your heart rate should go safely while exercising.

• A range of heart rates that you should reach to get maximum benefits from exercise.

A range of heart rates that you should reach to get maximum benefits from exercise. The range is 50-85% of your MHR.

• Heart Rate

  (HR)

• Resting Heart Rate (RHR)

• Target Heart Rate Zone (THRZ)

• Maximum Heart Rate (MHR)

What happens to your maximum heart rate (MHR)?

• As you get older, your max heart rate increases.

• As you get older, your max heart rate decreases.

• As you get older, your max heart rate stays the same.

Who has the higher MHR a 13-year-old couch potato or a 13-year-old athlete?

The ratio of chest compressions to rescue breaths when performing CPR on an adult or child is

• 30:2

• 15:2

• 5:2

• 60:2

The speed, or rate, of chest compressions when performing CPR on an infant, child, or adult is __________ times per minute.

• 60-80

• 80-100

• 100-120

• 200-220

You are performing CPR on an adult. Your compression depth should be about

• 1/3 the depth of the chest or about 1 1/2 inches.

• Right side and left side of chest

You have attached an AED to someone you suspect of being in cardiac arrest. The AED has analyzed the heart rhythm and advises a shock be delivered. What should you do next? 

• Make sure no one, including you, is in contact with the person before delivering the shock.

• Have the AED reanalyze to make sure the defibrillation is required.

• Immediately resume CPR, starting with chest compressions.

• Reassess the defibrillation pads, ensuring proper placement for directing shock through the heart.
