CPR

10 seconds

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

immediately restart CPR, beginning with chest compressions

after the AED delivers a shock, the rescuer should

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 to rise

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

10 seconds

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

turn on the AED

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

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

compression and ventilation rates for 2-rescuer CPR in the presence of an advanced airway

give a breath just until you see the chest rise

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

start CPR beginning with compressions

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

both chest compressions and breaths

if 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

maintain an open airway and give ventilations

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

bag-mask device

not recommended for a single rescuer to provide breaths during CPR

is the preferred chest compression technique for 2-rescuer CPR

the 2 thumb-encircling hands technique for the infant

15:2

the compression-to-breaths ratio for 2-rescuer child CPR is

30:2

the compression-to-ventilation ratio for 1-rescuer adult CPR is

15:2

the compression-to-ventilation ratio for 2-rescuer infant CPR is

2 inches (5 cm)

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

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

the recommended depth of chest compressions for an infant is

at least 100 compressions per minute

the recommended rate for performing chest compressions for victims of al ages is

the chest rises visibly

the rescuer knows the rescue breath for an infant victim is effective when

give breaths without chest compressions

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 at the rate fo 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

when the rescuer first sees a potential victim

when should the rescuer initially ensure that the scene is safe

on the lower half of the breastbone

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

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

which of the following victims needs CPR

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

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