BLS Flashcards
These techniques are based on the most current research and
are organized
into a systematic response called the Chain of Survival,
which begins with Basic Life Support (BLS).
The Chain of Survival provides the victim the
best chance to receive the care needed
and return to a healthy life.
According to the Centers for Disease Control (CDC), heart disease continues to be the leading cause of death in the United States
and is responsible for over 600,000 deaths every year.
Research continues to improve how we respond with life-saving techniques to emergencies.
The heart pumps blood through the lungs, where blood takes in oxygen and releases carbon dioxide.
This blood then returns to the heart where it is pumped out to vital organs
—the heart and brain—as well as the rest of the body.
When the heart stops,
blood flow stops, and the person quickly becomes unconscious
. Without blood flow, the heart and the brain quickly become damaged due to a lack of oxygen.
The actions that make up BLS
try to prevent or slow the damage until the cause of the problem can be corrected.
BLS improves a person’s chance of surviving until advanced care becomes available.
Taking the right action quickly and confidently
can make the difference between life and death for a person dealing with cardiac arrest.
Keys for BLS:
Quickly start the Chain of Survival.
Deliver high-quality chest compressions to circulate oxygen to the brain and vital organs.
Know when and how to use an Automated External Defibrillator (AED).
Provide rescue breathing.
Understand how to work with other rescuers as part of a team.
Know how to treat choking.
Initiating chain of survival
. To increase the odds of surviving a cardiac event
, the rescuer should follow the steps in the Adult Chain of Survival
Early initiation of BLS has been shown
to increase the probability of survival
for a person dealing with cardiac arrest
Paediatric chain of survival
Prevent arrest
Activate EMS
Perform early CPR
Advanced life support
Post cardiac arrest care
Recovery
Emergencies in children and infants are not usually caused by the heart.
Children and infants most often have breathing problems
that trigger cardiac arrest.
The first and most important step of the Pediatric Chain of Survival is prevention
Adult Chain of Survival
Activation of emergency response
Perform early CPR
Defibrillate with AED
Advanced life support
Post cardiac arrest
Recovery
Early initiation of BLS has been shown
to increase the probability of survival
for a person dealing with cardiac arrest.
To increase the odds of surviving a cardiac event,
the rescuer should follow the steps in the Adult Chain of Survival
Approximately every five years the International Liaison Committee on Resuscitation (ILCOR),
updates the guidelines for CPR and ECC (Emergency Cardiac Care).
The content contained herein is based on the most recent ILCOR publications on BLS
. Recommendations for adult basic life support (BLS)
from the 2020 Guidelines for CPR and ECC include the following:
⭐️The importance of early initiation of CPR by lay rescuers has been re-emphasized.
The risk of harm to the patient is low if the patient is not in cardiac arrest.
Bystanders should not be afraid to start CPR even
if they are not sure whether the victim is breathing or in Cardiac Arrest.
🤩A sixth link, Recovery, was added to the Chains of Survival for both Pediatric and Adults
.
🤩Care of the patient after the return of spontaneous circulation (ROSC)
requires close attention to
oxygenation,
blood pressure control,
evaluation for percutaneous coronary intervention,
targeted temperature management,
and multimodal neuroprognostication.
Continuation of bls guidelines for cpr and ecc
💕Because recovery from cardiac arrest
continues long after the initial hospitalization,
patients should have formal assessment and
support for their
physical,
cognitive,
psychosocial needs
💕After a resuscitation,
debriefing for lay rescuers, EMS providers,
and hospital-based healthcare workers
may be beneficial to support their mental health and well-being.
💕Management of cardiac arrest in pregnancy
focuses on maternal resuscitation,
with preparation for
early perimortem cesarean delivery
if necessary to save the infant
and
improve the chances of successful resuscitation of the mother.
What is the Simple Adult BLS Algorithm?
The Simple Adult BLS Algorithm is a streamlined sequence of actions
designed to assess and manage
life-threatening conditions
in adults aged
puberty and older.
By focusing on the most critical steps, the algorithm enables
rescuers to act quickly and confidently during emergencies.

Key Steps in the Simple Adult BLS Algorithm
- Check Responsiveness and Ensure Safety
- Activate Emergency Response System
- Assess Breathing
- Begin High-Quality CPR
- Use an Automated External Defibrillator (AED
- Continue CPR Cycles
- Check Responsiveness and Ensure Safety
Ensure Scene Safety:
Before approaching the victim,
ensure the environment is safe for you and the patient.
Check Responsiveness:
Firmly tap the victim’s shoulders and shout, “
Are you okay?”
to see if there is any response.
- Activate Emergency Response System
If Unresponsive:
Shout for help.
If someone is nearby,
instruct them to call emergency services and
get an AED.
Call emergency services
and activate speaker mode
if
you are alone
and have a mobile phone.
- Assess Breathing
Look for Normal Breathing:
Observe the chest for rise and fall.
Listen for normal breathing sounds.
If Not Breathing or Only Gasping:
Begin CPR immediately
following the adult BLS algorithm.
- Begin High-Quality CPR
Chest Compressions:
Place the heel of one hand on the center of the victim’s chest (lower half of the sternum).
Place your other hand on top, interlocking your fingers.
Keep your arms straight and shoulders directly over your hands.
Chest Compressions:
Place the heel of one hand on the center of the victim’s chest (lower half of the sternum).
Place your other hand on top, interlocking your fingers.
Keep your arms straight and shoulders directly over your hands.
Compression Depth: At least 2 inches (5 cm).
Compression Rate: 100 to 120 compressions per minute.
Allow Full Chest Recoil after each compression.
Ventilations:
After 30 compressions,
open the airway using the head-tilt-chin-lift method.
Pinch the victim’s nose closed and give two breaths, each over 1 second, watching for chest rise.
Avoid Excessive Ventilation to prevent complications.
- Use an Automated External Defibrillator (AED)
Attach the AED as soon as it is available.
Follow AED Prompts:
💕Turn on the AED and follow the voice instructions.
Pad Placement:
💕Apply AED pads to the victim’s bare chest as indicated.
💕Analyze Rhythm:
Ensure no one is touching the victim during analysis.
💕Deliver Shock if Advised:
💕If a shock is advised, ensure everyone is clear and press the shock button.
💕Resume CPR Immediately After Shock:
Continue CPR starting with chest compressions,
following the adult BLS algorithm.
- Continue CPR Cycles
Cycle Ratio:
Maintain cycles of 30 compressions and two breaths.
Minimize Interruptions:
Keep pauses in chest compressions to less than 10 seconds.
Reassessment:
Do not stop to check for a pulse or breathing until emergency services arrive
or the victim shows signs of life.
Importance of the Simple Adult BLS Algorithm
The adult BLS algorithm is designed to simplify the rescue process, making it easier to remember and execute during high-stress situations.
Key benefits include:
👉Immediate Action: Encourages quick response, which is critical for survival.
👉Standardized Procedure:
Provides a consistent approach that all rescuers can follow.
👉Enhanced Survival Rates:
Early and effective CPR using the adult BLS algorithm can significantly improve outcomes
One Rescuer BLS/CPR for Adults
Be Safe
Make sure the scene is safe before proceeding.
Move the person out of traffic.
Move the person out of water and dry the person. (
Drowning persons should be removed from the water and dried off;
they should also be removed from standing water
, such as puddles, pools, gutters, etc.)
Be sure you do not become injured yourself.
Assess the Person
Shake the person, tap their shoulder hard, and talk to them loudly.
Check to see if the person is breathing.
(Agonal breathing, which is occasional gasping and is ineffective, does not count as breathing.)
Call EMS
Send someone for help or to call your emergency number and to get an AED.
If alone, call for help while assessing for breathing and pulse
. (The ILCOR emphasizes that cell phones are available everywhere now and
most have a built-in speakerphone. Call for help without leaving the person.)
CPR
Begin sets of compressions and rescue breaths.
