To avoid fatigue, when should team roles alternate providing compressions?
every 5 cycles or 2 minutes
Which team role keeps track of interruptions in compressions?
timer/recorder
Which team role makes treatment decisions and assigns roles?
team leader
Which of the following are resuscitation triangle roles in a high-performance team?
-AED/Monitor/Defibrillator
-compressor
-airway
While performing high-quality CPR, when do pauses in compressions typically occur?
-intubation
-compressor switches
-defibrillation
-rhythm analysis
-pulse checks
Assesses the patient and provides compressions
compressor
Operates the AED and alternates with the Compressor after every 5 cycles or 2 minutes to
avoid fatigue
monitor/defibrillator
,provides ventilation
airway
Assigning your team members to individual roles and outlining what each member needs to
do during the resuscitation attempt is an example of what element of high-performance team
dynamics?
clear roles and responsibilities
You and your team have initiated compressions and ventilation. The AED was attached, and
"no shock" was advised. Your team has continued CPR for 1 minute. You tell your team in a
respectful, clear, and calm voice, "Leslie, during the next analysis by the AED, I want you and
Justin to switch positions, and I want you to perform compressions for the next cycle." Leslie
replies, "Got it. Next time the AED analyzes, I will switch with Justin and assume the role of
Compressor."
This is an example of which element of high-performance team dynamics?
closed-loop communication
As Team Leader, you notice that your Compressor is pushing too fast. It is important to correct
actions that are incorrect, but it is also important to be tactful when delivering this correction
to a colleague.
This is an example of what element of team dynamics?
constructive intervention
What action can you take as a team during and after a resuscitation attempt that helps
individual team members perform better and brings awareness to system strengths and
deficiencies?
debriefing
AED special considerations
,hairy chest, water, transdermal medicine patch, implanted defibrillator or pacemaker,
defibrillation for infants less than 1 year of age
Hairy chest
-if your AED has 1 set of pads and a razor, quickly shave the area and then apply the pads
-if your AED has 2 sets of pads, use the first set to remove the hair. Apply the first set of pads,
press them down so they stick as much as possible, and quickly pull them off. Then apply the
new, second set of pads
Water
-if someone is lying in water, quickly move the victim to a dry area; if the victim is lying is snow
or a small puddle, use the AED
-if the chest is covered with water or sweat, wipe the chest before attaching the pads
Transdermal medicine patch
-do not place the pad directly over a medicine patch
-take the patch off and quickly wipe the chest before you put on the pad
Implanted defibrillator or pacemaker
-if you see a lump indicating a device, avoid placing the pad directly over it
Defibrillation for infants less than 1 year of age
-a manual defibrillator is preferred rather than an AED
-if a manual defibrillator is not available, an AED with a pediatric does attenuator is preferred
-if neither is available, you may use an AED without a pediatric dose attenuator
What are examples of effective team dynamics?
clear roles and responsibilities
debriefing
constructive intervention
, knowledge sharing
always take the lead
What does a chest compression feedback device monitor?
compression rate
compression depth
chest recoil
Mouth-to-mouth breaths: adults, children, and infants
-3 steps
-mouth-to-mouth breathing is a quick and effective way to provide oxygen to a victim when a
barrier mask is not available
-each breath you take contains 21% oxygen. When you provide a rescue breath, the air you
breathe into a victim contains about 17% oxygen
Step 1: mouth-to-mouth breaths: adults, children, and infants
-hold the victim's airway open with a head tilt-chin lift
-pinch the nose closed with your thumb and index finger
Step 2: mouth-to-mouth breaths: adults, children, and infants
-take a regular breath and seal your lips around the victim's mouth, creating an airtight seal
-give 1 breath and blow for 1 second
-watch for the chest to rise as you give each breath
Step 3: mouth-to-mouth breaths: adults, children, and infants
-give a second breath (blowing for about 1 second) while watching for chest rise
Your adult friend suddenly collapse at home, and you determine she needs CPR. You begin
CPR, starting with chest compressions, and are about to deliver breaths by using mouth-to-
mouth breaths. You open the airway with a head tilt-chin lift.
What is the sequence of your next actions?
