Safety Training. Heart code BLSWhat are the components of a pulse check in an unresponsive victim? - answer- Use
two or three fingers to locate the pulse
- Assess for a pulse for at least 5 but no more than 10 seconds
- Feel the pulse in the groove to the side of the trachea
What is the correct chest compression rate for adults? - answer100 to 120/min
Feedback devices monitor CPR what aspects? - answer Rate, depth, recoil
How do you open the airway for breaths if a single rescuer is present? - answer Head
tilt - chin lift
A bag-mask device is used to provide what to a victim who is not breathing or not
breathing normally? - answer Positive-pressure ventilation
How are breaths delivered using a bag-mask device? - answer1 breath over 1 second,
while watching the chest rise
Two life threatening arrhythmias that can cause cardiac arrest are pulseless ventricular
tachycardia and what? - answerVentricular fibrillation
What is an AED? - answerDevice that analyzes the heart rhythm to identify the
presenceof an arrhythmia that can be corrected by a shock
Where should AED pads be placed in the anterolateral placement for adults and
children 8 years or older? - answerBelow the right collarbone and side of the left nipple
What are correct actions to take for scene safety and assessment? - answerVerify
scene safety, activate the emergency response system and get an AED, check for
responsiveness, look for no breathing and only gasping and check pulse
After positioning yourself directly above the victim's head, what is the correct order of
steps for using a bag-mask device? - answer1. 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 yoou lift the jaw to hold
the airway open
3. Squeeze the bag to give breaths (1 second each) while watching for chest rise
, Where should AED pads be placed in the anteroposterior placement for adults and
children 8 years or older? - answerCenter of the chest and center of victim's back OR
left side of chest between breastbone and nipple and left side of victim's back
Why is an AED needed? - answerTo analyze the heart rhythm and provide a shock
When should the rescuer operating the AED clear the victim? - answerDuring analysis
and before shock delivery
What is recommended to minimize interruptions in compressions when using an AED? -
answerContinue with high-quality CPR until an AED prompts the clear, when 2 or more
rescuers are present, one rescuer should continue chest compressions while the other
prepares the AED, and if no shock is advised and after any shock delivery, immediately
resume high-quality CPR, starting with chest compressions
What is the preferred method for pulse check in an infant? - answerPlace 2 to 3 fingers
on the inside of the upper arm, midway betweenthe infant's elbow and shoulder
Critical components of chest compressions: Children - answerRate: 100 to 120/min
Depth: Approximately 2 inches (5 cm)
Hand Placement: 2 hands or 1 hand on the lower half of the breastbone
Chest Recoil: Allow complete recoil; do not lean on the chest
Minimizing Interruptions: Limit interruptions to less than 10 seconds
During CPR on a child, you should place 1 or 2 hands over the lower half of the
breastbone - answer
During CPR on a child, interruptions to chest compressions should be limited to no
more than how many seconds? - answer10
When performing high-quality CPR on a child, what is the correct depth of
compression? - answerApproximately 2 inches (5 cm)
Critical components of chest compressions: Infants - answerRate: 100 to 120/min
Depth: Approximately 1 1/4 inches (4 cm)
Hand Placement:
- 1 rescuer places 2 fingers in center of chest just below the nipple line
- 2 rescuers use the 2 thumb-encircling hands technique in the center of the chest, just
below the nipple line
- 1 rescuer may also use the 2 thumb-encircling hands techniqe or the of 1 hand
Chest Recoil: Allow complete recoil; do not lean on the chest
Minimizing Interruptions: Limit interruptions to less than 10 seconds
Compression-to-ventilation ratio: Infants and Children - answerRatio for 1 rescuer is
30:2
Ratio for 2 or more rescuers is 15:2
