Welcome to the Basic Life Support (BLS) algorithms and training by United Medical Education. Here we will discuss basic life saving interventions for patients in respiratory and cardiac distress and the importance of teamwork in a medical emergency. The life saving interventions of BLS are primarily for the purpose of maintaining circulation and oxygenation of the brain and other vital organs until Advanced Cardiac Life Support (ACLS) and other interventions can be initiated by trained healthcare providers.

CPR: for adultsCABD (Circulation, Airway, Breathing, Defibrillate)There is a common acronym in BLS used to guide providers in the appropriate steps to assess and treat patients in respiratory and cardiac distress. This is CAB-D (Circulation, Airway, Breathing, Defibrillate). The following scenario will help guide you in performing CAB-D. You find an adult lying on the ground. Assess to make sure the scene is safe for you to respond to the down patient. Assess Responsiveness: Stimulate and speak to the adult asking if they are ok. Look at the chest and torso for movement and normal breathing.
Place patient supine on a hard flat surface. Circulation
If the patient has a pulse: Move to the airway and rescue breathing portion of the algorithm:
If the patient doesn’t have a pulse: Begin 5 cycles of CPR (lasts approximately 2 minutes). Start with chest compressions:
1 cycle of adult CPR is 30 chest compressions to 2 rescue breaths. If two providers are present: switch rolls between compressor and rescue breather every 5 cycles. AirwayIn the event of an unwitnessed collapse, drowning, or trauma: Use the Jaw Thrust maneuver. (This maneuver is used when a cervical spine injury cannot be ruled out.):
In the event of a witnessed collapse with no reason to assume a C-spine injury: Use the Head Tilt-Chin Lift maneuver:
BreathingScan the patients chest and torso for possible movement during the “assess unresponsiveness” portion of the algorithm. Watch for abnormal breathing or gasping. If the patient is breathing adequately: Continue to assess and maintain a patent airway and place the patient in the recovery position. (Only use the recovery position if its unlikely to worsen patient injury.) If the patient is not breathing or is breathing inadequately: If the patient has a pulse:
If the patient has no pulse:
During normal CPR without an advanced airway:
During normal CPR with an advanced airway:
If patient has a pulse and no CPR is required:
If there is a foreign body obstruction:
Recovery position(lateral recumbent or 3/4 prone position):This position is used to maintain a patent airway in the unconscious person.
Continue to assess and maintain access of airway. DefibrillateArrival of the AED (Automated External Defibrillator)
A short pause in CPR is required to allow the AED to analyze the rhythm. If the rhythm is not shockable:
If the shock is indicated:
CPR: for infants 0-1 in ageCABD (Circulation, Airway, Breathing, Defibrillate)An infant is found lying on the ground. Assess to make sure the scene is safe for you to respond to the down patient. Assess Unresponsiveness: Lightly shake or tap the infant’s foot and say their name. Look at the chest and torso for movement and normal breathing. If the infant is unresponsive:
CirculationFeel for either the brachial or femoral pulse (Do not check for more than 10 seconds). If the infant has a pulse: Move to the airway and rescue breathing portion of the algorithm.
If the infant doesn’t have a pulse: Begin 5 cycles of CPR (lasts approximately 2 minutes). Start with Chest Compressions:
(One Provider: 1 cycle is 30 chest compressions to 2 rescue breaths) (Two Providers: 1 cycle is 15 chest compressions to 2 rescue breaths) If you have two providers: switch rolls between compressor and rescue breather every 2 minutes or 5 cycles of CPR. AirwayIn the event of an unwitnessed collapse, drowning, or trauma: Use the Jaw-Thrust maneuver. (This maneuver is used when cervical spine injury cannot be ruled out.):
In the event of a witnessed collapse and there’s no reason to assume C-spine injury: Use the Head Tilt-Chin Lift maneuver:
BreathingScan the patients chest and torso for possible movement during the “assess unresponsiveness” portion of the algorithm. Watch for abnormal breathing or gasping. If the infant has adequate breathing:
If the infant is not breathing or is inadequately breathing: If the infant has a pulse:
If the infant doesn’t have a pulse:
During normal CPR with an advanced airway:
If the patient has a pulse and no CPR is required:
Recovery position for infants
DefibrillateArrival of AED (Automated External Defibrillator)
A short pause in CPR is required to allow the AED to analyze the rhythm. If the rhythm is not shockable:
Manual defibrillators are preferred for infant use. If the manuals defibrillator is not available the next best option is an AED with a pediatric attenuator. An AED without a pediatric attenuator can also be used. CPR: for a child older than 1 year of age to pubertyCABD (Circulation, Airway, Breathing, Defibrillate)You find a child lying on the ground. Assess to make sure the scene is safe for you to respond to the down patient.
(One provider) If alone and collapse is un-witnessed:
If alone and collapse is witnessed:
Place patient supine on a hard flat surface. Circulation
Move to the airway and rescue breathing portion of the algorithm:
Begin 5 cycles of CPR (lasts approximately 2 minutes) Start with chest compressions:
(One Provider: 1 cycle is 30 chest compressions to 2 rescue breaths) (Two Providers: 1 cycle is 15 chest compressions to 2 rescue breaths) If you have two providers: switch rolls between compressor and rescue breather every 2 minutes or 5 cycles of CPR. AirwayIn the event of an unwitnessed collapse, drowning, or trauma: Use the Jaw-Thrust maneuver. (this maneuver is used when cervical spine injury cannot be ruled out):
In the event of a witnessed collapse and there’s no reason to assume a C-spine injury: Use the Head Tilt-Chin Lift maneuver.
BreathingScan the patients chest and torso for possible movement during the “assess unresponsiveness” portion of the algorithm. Watch for abnormal breathing or gasping that will require additional ventilatory support. Continue to assess and maintain a patent airway and place the child in the recovery position. (Only use the recovery position if its unlikely to worsen patient injury) If not or inadequate breathing:
During normal CPR without an advanced airway: During normal CPR with an advanced airway:
If patient has a pulse and no CPR is required:
If foreign body obstruction:
Recovery position (lateral recumbent or 3/4 prone position)This position is used to maintain a patent airway in the unconscious person.
DefibrillateArrival of AED (Automated External Defibrillator)
A short pause in CPR is required to allow the AED to analyze the rhythm. If rhythm is not shockable:
An AED with a pediatric attenuator should be used in children under 8 years of age if available. An AED without a pediatric attenuator can also be used. Choking: Adult to Child Over 1 Year Old
Signs and symptoms of a child/adult choking: Universal signal for choking: Partial airway obstruction may result in stridor or a high-pitched audible noise during respiration. Partial airway obstruction may allow for a productive cough or allow the patient to speak. Get the patient’s attention and ask them if they are choking. If partial airway obstruction:
If complete airway obstruction:
How to perform the Heimlich maneuver:
If patient becomes unconscious:
Before attempting rescue breaths during normal CPR, assess the airway, removing any visually present obstruction. Choking: Infant Under 1 Year OldSigns and symptoms of an infant choking: With complete airway obstruction, the infant is unable to speak, cry, or provide any sounds of respiration. The infant may be confused, weak, obtunded, or cyanotic. Partial airway obstruction may result in stridor or a high-pitched audible noise during respiration. If the child has a partial airway obstruction, powerful cough, or strong audible cry, do not attempt the Heimlich maneuver. If signs and symptoms of choking are present and infant is conscious:
Interventional Back Blows:
Interventional Chest Thrusts:
Congratulations!You're Ready to Certify.When should a responder perform a finger sweep?After vomiting stops, clear the victim's airway by wiping the mouth out using a finger sweep (Figure 6).
When should a blind finger sweep be performed by a layperson to remove an object on a choking victim?When should a blind finger sweep be performed by a layperson to remove an object on a choking victim? Never perform a blind finger sweep. Place the second AED pad: -on the left side of the chest.
What is the correct way to perform back blows?To carry out a back blow on an adult:. Stand behind them and slightly to one side. Support their chest with 1 hand. ... . Give up to 5 sharp blows between their shoulder blades with the heel of your hand. ... . Check if the blockage has cleared.. If not, give up to 5 abdominal thrusts.. What are the acceptable techniques for administering rescue breathing?Give 2 gentle puffs or breaths of air instead of a deep breath. Each puff is given 2 seconds apart because each gentle breath should last 1 second. If the chest rises, breathe a gentle puff or breathe into the victim's mouth a second time. If the chest doesn't rise, tilt the victim's head back and chin down again.
