BLS Basics
BLS is defined as what type of emergency care?
Noninvasive emergency life-saving care
The primary assessment and determination of unresponsiveness should take less than this amount of time.
10 Seconds
CPR is used to reestablish these two physiologic functions.
Circulation and artificial ventilation
The preferred airway maneuver when no spinal injury is suspected.
Head tilt-chin lift maneuver
What should be applied to a cardiac arrest patient as soon as this is available.
AED
The three priorities that form the foundation of BLS.
Airway, Breathing, and Circulation
In adults, cardiac arrest usually occurs before this.
Respiratory Arrest
The correct compression-to-ventilation ratio for one-rescuer adult CPR.
30:2
This condition can occur if ventilations are too fast or too forceful.
Gastric Distention
Pediatric AED pads should be used when available, but if not, adult pads should be placed using this configuration.
Anterior-Posterior Placement
ALS differs from BLS by including cardiac monitoring, IV medications, and this.
Advanced Airway Adjuncts
The pulse check should take at least this long, but no more than this long.
5 to 10 seconds
Chest compression fraction should be at least this percentage.
80 Percent
The airway maneuver used when spinal injury is suspected.
Jaw-thrust maneuver
Name one special situation that must be considered before AED pad placement.
pacemaker, wet patient, transdermal medication patch
Permanent brain damage is possible if the brain is without oxygen for this long.
4 to 6 minutes
In infants and children, cardiac arrest most often follows this.
Rescuers should switch compressors at this interval to maintain CPR quality.
Every 2 minutes
A patient who is breathing adequately but has a decreased level of consciousness should be placed in this position.
Recovery Position
Standard resuscitation measures take priority over naloxone administration in this type of emergency.
Opioid overdose
Name all six links in the AHA Chain of Survival.
recognition and activation, early CPR, rapid defibrillation, basic and advanced EMS, ALS and post-arrest care, and recovery
Why delaying CPR while over-checking a pulse is dangerous.
delayed circulation and oxygen delivery to the brain
The circumferential chest compression device made of a constricting band and backboard.
load-distributing band
For a patient with a stoma, where is the bag-mask device placed?
directly over the stoma
When a valid DNR cannot be confirmed, this is the correct action.
