General Concepts of Basic Life Support Flashcards
these life-saving techniques based on the most current research are organized into a systematic response called
Chain of Survival
improves a person’s chance of surviving until advanced care becomes available
BLS
steps in Adult Chain of Survival
recognize sx and activate EMS (emergency medical service)
perform early CPR
defibrillate with AED
advanced life support
post-cardiac arrest care
pediatric chain of survival
prevent arrest perform early CPR activate EMS advanced life support post-cardiac arrest care
emergencies in children are usually caused by
breathing problems that trigger cardiac arrest
the first and most important step of the Pediatric Chain of survival
prevention of arrest
Resuscitation research continues to show that _________ is increasing survival rates for hospital discharge
high-quality CPR
The characteristics that define high-quality compressions remain as pushing
hard and fast
CPR compression rate per minute
100-120 per minute
the increase in chest compressions (100-120/ minute instead of 100/minute) leads to
decrease CO due to incomplete cardiac filling during recoil
The 2015 guideline now defines the target depth for adult compressions to be between
2-2.4 inches (5-6 centimeters)
if the adult compressions are delivered beyond 2-2.4 inches (5-6 centimeters) this will result to
increased risk of resuscitation related injuries (rib fractures)

are most valuable in saving a life
high-quality chest compressions
What is the intention of changing to CAV+B
encourage early CPR and avoid bystanders interpreting agonal breathing as signs of life and withholding CPR
Shallow breathing pattern that is often related to cardiac arrest and death
agonal breathing
High-quality CPR is key and consists of doing the following:
- Start compressions w/in 10 seconds of recognition of cardiac arrest
- Push hard and fast. Keep compression rate of at least 100 /minute for all persons.
- Keep compression depth of between 2-2.4 inches for adults and (2 in, 1/3 of the depth of the chest) children, and about 1.5 inches (4 cm) for infants.
- Allow complete chest recoil after each compression.
- Minimize interruptions in CPR, except to use an AED or to change rescuer positions. -limit interruptions to less than 10 seconds
Give effective breaths that make the chest rise
• Avoid excessive ventilate.
is cricoid pressure routinely performed
no
Cricoid pressure
other name
Sellick maneuver
what is the intention of doing cricoid pressure
technique used in endotracheal intubation to reduce the risk of regurgitation
how is cricoid pressure performed
application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it
