Scene Safety - ANSWER make sure the scene is safe for you and the victim
how to check for responsiveness - ANSWER -tap the victim's shoulders and shout "are you ok?"
-if the victim is not responsive, active the emergency response system via mobile device
-get the AED or send someone to do so
how to assess for breathing and a pulse - ANSWER -assess at the same time; should take no more than

-to check for breathing, scan the victim's chest for rise and fall for no more than 10 seconds
--if the victim is not breathing or only gasping, be prepared to begin high-quality CPR
-to perform a pulse check on an adult, feel for a carotid pulse
how to find and feel for the carotid pulse - ANSWER 1) locate the trachea (on the side closest to you),
using 2 or 3 fingers
2) slide those fingers into the groove between the trachea and muscles at the side of the neck, where
you can feel the carotid pulse
3) feel for a pulse for at least 5 but no more than 10 seconds; if you do not definitely feel a pulse, begin
CPR, starting with chest compressions.
critical components of chest compressions in adults - ANSWER -place the victim on a firm, flat surface,
such as a floor or backboard
,-rate: 100-120/min
-depth: at least 2 inches (5 cm)
-chest recoil: allow complete recoil
-minimizing interruptions: limit interruptions to less than 10 seconds
what does a chest compression feedback device monitor? - ANSWER -compression depth
-chest recoil
-compression rate
how to open the airway for breaths - ANSWER 1. Place one hand on the victim's forehead, and push with
your palm to tilt the head back
2. Place fingers of the other hand under the bony part of the lower jaw, near the chin
3. Lift the jaw to bring the chin forward.

After positioning yourself directly above the victim's head, what is the correct order of steps for using a
bag-mask device? - ANSWER 1) Place the mask on the victim's face, using the bridge of the nose as a
guide for the correct position
2) Use the E-C clamp technique to hold the mask in place while you lift the jaw to hold the airway open
3) Squeeze the bag to give breaths (1 second each) while watching for chest rise
how to use a bag-mask device - ANSWER -Position yourself directly above the victim's head
1. place the mask on the victim's face, using the bridge of the nose as a guide for correct position.
, 2. Use the E-C clamp technique
-Perform a head tilt.

-Use the thumb and index finger of one hand to make a "C" on the side of the mask, pressuring the
edges of the mask to the face.
-Use the remaining fingers to lift the angles of the jaw, open the airway, and press the face to the mask.
3. Squeeze the bag to give breaths while watching for chest rise. Deliver each breath over 1 second. If
there are 2 rescuers:
-Rescuer 1: Positioned directly above the victim, opens the airway and positions the bag-mask device.
-Rescuer 2: Positioned at the victim's side, squeezes the bag.
2 life-threatening arrhythmias that can cause cardiac arrest are pulseless ventricular tachycardia and -
ANSWER ventricular fibrillation
AED - ANSWER automated external defibrillator
-a device that analyzes the heart rhythm to identify the presence of an arrhythmia that can be corrected
by a shock
-lightweight, portable device
-simple to operate
-uses voice prompts, lights, and on-screen messages
After an AED delivers a shock, what should the rescuers do next?
a) clear the victim for another rhythm analysis
b) complete a pulse check
c) resume CPR, starting with chest compressions
d) give 2 breaths and resume CPR - ANSWER c) resume CPR, starting with chest compressions
how to use an AED - ANSWER 1. Power on the AED if needed. Follow the prompts.
2. Choose adult pads for victims 8 years of age and older. Attach the adhesive AED pads to the victim's
bare chest.
