(2022) BLS HeartCode *online*| Questions and
Answers
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 are breaths delivered using a bag-mask device? Answer- 1 breath over 1
second, while watching for chest rise
Why an AED is needed Answer- - Most sudden cardiac arrests are triggered by
abnormal heart rhythms called arrhythmias
- Two life-threatening arrhythmias that can cause cardiac arrest are pulseless
ventricular tachycardia(pVT) and ventricular Fibrillation (VF) where the heart's electrical
impulses suddenly become chaotic and ineffective
- Blow flow to the brain stops abruptly, and the victim loses consciousness
-Death usually follows unless a normal heart rhythm and pulse are restored within
minutes
Why is an AED needed? Answer- To analyze the heart rhythm and provide a shock
After an AED delivers a shock, what should the rescuers do next? Answer- Resume
CPR, starting with chest compressions
How to Use an AED Answer- Step 1: Power on the AED if needed
- Follow the prompts (as a guide to next steps)
Step 2: Choose adult pads for victim 8 years of age and older
- Attack the adhesive AED pads to the victim's bare chest
- Follow the diagrams on the pads
Step 3: When AED prompts you, clear the victim during analysis. Be sure no one is
touching the victim, not even the rescuer in charge of giving breaths
- Some AEDs will tell you to push a button to allow the AED to begin analyzing the heart
rhythm; others will do automatically
- The AED may take a few seconds to analyze
,Step 4:
If the AED advises a shock:
- it will charge and then tell you again to clear the victim
- Clear the victim before delivering the shock
- Pressure the shock button
- The shock will produce a sudden contraction of the victim's muscles
- After any shock delivery, immediately resume CPR
If no shock is needed:
- Immediately resume CPR, starting with compressions
Where should the AED pads be placed in the anterolateral placement for adults and
children 8 years or older? Answer- -Below the right collarbone
-Side of left nipple
AED pad placement: Adults and children 8 years and older Answer- Anterolateral
Placement:
- place one pad directly bellow the right collarbone
- Place the other pad to the side of the left nipple, with the top edge of the pad a few
inches below the armpit
Anteroposterior placement:
- Place one AED pad on the left side of the chest, halfway between the tip of the
breastbone and left nipple with upper edge of the pad below the nipple line
- Place the other pad on the left side of victim's back, beneath the should blade, next to
the spine
What is recommended to minimize interruptions in compressions when using an AED?
Answer- - Continue with a high-quality CPR until an AED prompts to clear
- If no shock is advised and after any shock delivery, immediately resume high-quality
CPR, starting with chest compressions
- When 2 or more rescuers are present, one rescuer should continue chest
compressions while the other prepares the AED
Scene Safety, Responsive and Assessment Answer- The first step in the adult BLS
sequence for 1 or 2 or more rescuers is to verify the scene is safe
Check for responsiveness and get help. Tap the victim's should and shout, "Are you
OK?
If the victim is not responsive, shout for nearby help. If you are alone get the
AED/defibrillator; if someone else is available send that person to get it
, Next, look for no breathing or only gasping and check the pulse simultaneously. Is a
pulse definitely felt within 10 seconds?
If there is normal breathing and a pulse felt, monitor until emergency responders arrive
If there is no normal breathing and pulse is felt, provide rescue breathing, Give 1 breath
every 6 seconds, or 10 breaths/min. Check the pulse every 2 minutes and if there is no
pulse, start CPR. If possible opioid overdose, administer naloxone if available per
protocol
If there is no normal breathing or only gasping and a pulse is not felt, start CPR.
Perform cycles of 30 compressions and 2 breaths and use the AED as soon as it is
available
Once the AED arrives, check the rhythm
If the rhythms is shockable, give 1 shock and resume CPR immediately for 2 minutes
until prompted by the AED to allow a rhythm check
If rhythm is nonshockable, resume CPR immediately for 2 minutes, until prompted by
the AED to allow a rhythm check
Continue CPR until ALS provider take over or the victim starts to move
Adult BLS algorithms for health care providers Answer- Verify Scene Safety
Check for Responsiveness
- Tap the victim's shoulders and shout, "Are you OK?"
- If the victim is not responsive, shout for nearby help.
- Activate the emergency response system via mobile device
- Get the AED or send someone to do so
Look for no breathing or only gasping and check the pulse( simultaneously). Is a pulse
definitely felt within 10 seconds?
Normal breathing, pulse felt
- monitor until emergency responders arrive
No normal breathing, pulse felt
- 1 breath every 6 seconds, or 10 breaths/min
- Check the pulse every 2 min
- If no pulse, start CPR
- If possible opioids overdose, administer naloxone if available per protocol
No normal breathing and only gasping, pulse not felt
