high quality CPR includes starting compressions within how many seconds after recognition of cardiac arrest in adults?

10

The 2010 AHA guidelines for CPR and ECC recommend that to identify cardiac arrest in an unresponsive victim with no breathing (or no normal breathing), a healthcare provider should check a pulse for no more than

10 seconds

The proper compression rate for victims of all ages is at least

100 compressions per minute

The compression to breaths ratio for 2 rescuer child CPR is

15:2

The compression to breaths ratio for 2 rescuer infant CPR is

15:2

The depth of chest compressions for an adult victim should be at least

2 inches ( 5cm)

which of the following is the preferred chest compression technique for 2 rescuer cpr in an infant?

2 thumb encircling hands

The compression to ventilation ratio for 1 rescuer adult CPR is

30:2

The compression to ventilation ratio for 1 rescuer infant CPR is

30:2

The compression to ventilation ratio for 2 rescuer adult CPR is

30:2

compression to ventilation ratio for 1 rescue child CPR is

30:2

to reduce rescuer fatigue during team CPR, compressor roles should be switched about every

5 cycles

In an unresponsive infant is not breathing and has a heart rate of 53 beats per minute and signs of poor perfusion despite oxygenation and ventilation with a bag and mask, which of the following should you perform?

Both chest compressions and breaths

Which of the following options lists the correct compression and ventilation rates for 2 rescuer CPR in the presence of an advanced airway?

Compress at a rate of at least 100 per minute, 1 breath every 6 to 8 seconds

During bag-mask ventilation, which of the following is recommended to minimize the risk of gastric inflation?

Give a breath just until you see the chest rise.

Where should the hands be placed to perform chest compressions on an adult?

On the lower half of the breastbone

The rescuer knows the rescue breath for an infant victim is effect when

The chest rises visibly

After the airway is opened, which of the following correctly states the proper technique for delivering mouth to mouth ventilation?

The rescuer opens the airway seals his or her mouth over the victim's mouth pinches the victim's nose closed and gives 2 breaths while watching for the chest rise

After the airway is opened, which of the following correctly states the proper technique for delivering mouth-to-mouth ventilation?

The rescuer opens the airway seals his or her mouth over the victim's mouth pinches the victims nose closed and gives 2 breaths while watching for the chest to rise

when is it appropriate to move an adult victim who needs CPR

When the adult victim is in a dangerous environment

When should the rescuer initially ensure the scene is safe?

When the rescuer first sees a potential victim

which of the following victims needs CPR??

a victim unresponsive with no normal breathing and no pulse

which of the following victims needs CPR?

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

Why is it important to compress to the appropriate depth during CPR

adequate depth of compression is needed to create blood flow during compressions

why is it important to compress to the appripriate depth during CPR?

adequate depth of compression is needed to create blood flow during compressions

if an AED is used for a child less than 8 years of age

adult pads/dose may be used ONLY IF pediatric pads/dose attenuator is not available

complete chest recoil contributes to CPR success by

allowing the heart to refill with blood between compressions

The recommended rate for performing chest compressions for victims of all ages is

at least 100 compressions per minute

The recommended depth of chest compressions for an infant is

at least one third the depth of the chest, approximately 1.5 inches (4 cm)

The correct depth of chest compressions for a child is

at least one third the depth of the chest, approximately 2 inches (5 cm)

What shoudl a single rescuer NOT use to provide breaths during CPR?

bad mask device

which of the following ventilation devices/techniques is not recommended for a single rescuer to provide breaths during CPR?

bag-mask device

what is the correct compression and ventilation rates for 2 rescuer CPR in the presence of an advanced airway?

compress at a rate of at least 100 minute per min, 1 breath every 6 to 8 seconds.

which of the following is a characteristic of high quality CPR in adults?

compressing at a depth of at least 2 inches

which of the following correctly compares characteristics of chest compressions in adults with those in infants and children

compression depth: adults at least 2 inches for children/infants, at least one third the depth of the chest

when administering breaths by using a bag-mask device for a child who is not breathing, but does have a pulse, the rescuer should

give breaths at the rate of 1 breath every 3 to 5 seconds

when administering breaths by using a bag-mask device for a child who is not breathing, but does have a pulse, the rescuer should..

give breaths given at a rate of 1 breath per 3 to 5 seconds

When a child has a heart rate greater than 60 per minute and a pulse but is not breathing effectively the rescuer should

give breaths without chest compressions

gastric inflation is more likely to occur if the rescuer

gives breaths too quickly or with too much force

After the AED delivers a shock, the rescuer should

immediately restart CPR, beginning with chest compressions

IF A VICTIM has a foreign body airway obstruction unresponsive rescuer should send someone to active emergency response system and ....

immediately start CPR beginning with compressions

Where should a rescuer attempt to palpate the brachial pulse in an infant?

inside the upper arm, between the elbow and shoulder

The 2 thumb encircling hands technique for the infant

is the preferred chest compression technique for 2 rescuer CPR

interruptions in chest compressions should be

limited to < 10 seconds

In 2 rescuer CPR, while the first rescuer begins chest compressions, the second rescuer should

maintain an open airway and give ventilations

which of the following is a characteristic of high quality CPR?

minimizing interruptions in chest compressions

IF a victim of foreign body airway obstruction becomes unresponsive, the rescuer should send someone to activate the emergency response system and immediately

start CPR beginning with chest compressions

the rescuer should deliver a shock with an AED after

the AED advises a shock, charges, and prompts the rescuer to push the shock button

As soon as an AED becomes available, which of the following is the first step the rescuer should perform to operate the AED?

turn on the AED

After you identify an unresponsive victim with no breathing (or no normal breathing) and no pulse, chest compressions should be initiated

within 10 seconds
