Q

Seal pocket mask against face :

A

Q

What is No. 1 cause of death in the world?

How many per year?

Study These Flashcards
A
  • heart disease

* more than 17 million

23
Q

Locating the femoral artery pulse in a child :

Study These Flashcards
A

place 2 fingers in the inner thigh, midway between the hipbone and the pubic bone and just below the crease where the leg meets the torso

24
Q

Collapse sudden and witnessed of a child, next step?

Study These Flashcards
A

Leave the victim to activate the emergency response system

25
Signs of poor perfusion : (4)
* temperature - cool extremities * AMS - continued decline in consciousness/responsiveness * weak pulses * skin - paleness, mottling (patchy appearance) and later cyanosis
26
Maximize airway patency by positioning the infant with the neck in a neutral position, which is?
The external ear canal is level with the top of the infant’s shoulder
27
Rescue breaths for pediatric -
1 breath every 3-5 seconds, or 12-20 breaths/min
28
One commonly used method for reducing AED shock dose for Peds? Reduces shock dose by how much?
* Pediatric dose attenuator | * about two thirds
29
For infants, what is preferred to an AED?
Manual defibrillator
30
Advanced airway in place ventilation?
1 breath every 6 seconds (10 breaths per minute) for adults, children, and infants
31
Opioid overdose is now responsible for killing more adults that what?
Vehicular collisions
32
Age definitions : Adults - Children - Infants -
* Adolescents (ie, after the onset of puberty) and older * 1 year of age to puberty * Less than 1 year of age (excluding newly born infants in the delivery room)
33
Your approach to a resuscitation attempt - your response will be determined by : (4)
* Available emergency equipment * Availability of trained rescuers * Level of training expertise * Local protocols
34
What are crucial for survival from cardiac arrest?
Early recognition and CPR
35
For adult patients who are in the hospital, cardiac arrest usually happens as a result of what?
Serious respiratory or circulatory conditions that get worse
36
Rapid defibrillation in combination with high-quality CPR can increase chances of survival by how much?
Double or triple chances of survival
37
In children, cardiac arrest is often secondary to what?
Respiratory failure and shock
38
Which CPR skills you use will depend on ? (3)
* Your level of training * Experience * Confidence
39
What will determine CPR efforts?
The type of victim as well as the availability of equipment and other rescuers to assist
40
Research has shown what makes the shock more likely to be effective?
If rescuers minimize the interval between the last compression and shock delivery
41
What is associated with a greater likelihood of ROSC, shock success, and survival to hospital discharge?
Shorter duration of interruptions in chest compressions
42
The elements of team dynamics can be grouped into 3 categories :
* Roles during a resuscitation attempt * What to communicate * How to communicate
43
Who alternates with the compressor every 5 cycles or 2 mins?
The AED/Monitor/Defibrillator team member
44
Why is the 2 Thumb Encircling Technique the preferred technique in infant CPR w/2 rescuers?
* Produces better blood supply to the heart muscles * Helps ensure consistent depth and force of chest compressions * May generate higher blood pressures
45
A pediatric dose attenuator reduces the shock dose by how much?
By about two thirds
46
Most out of hospital cardiac arrests happen unexpectedly and from?
Underlying cardiac problems
47
Successful outcome (if out of hospital arrests) depends on what?
Early bystander CPR and rapid defibrillation
48
Sudden cardiac arrest is often what type of problem?
Rhythm
49
Cardiovascular disease claims more lives than what?
All forms of cancer combined
50
When is air likely to enter the stomach rather than the lungs?
If you give breaths too quickly or with too much force, or too much volume
51
What is an important tool for identifying whether or not opioid use may be involved in a life threatening emergency?
Scene assessment
52
You can tell if you have successfully removed an airway obstruction in an unresponsive victim if you can :
* feel air movement and see the chest rise when you give breaths * see and remove a foreign body from the victim’s mouth
53
30 compressions should be administered in no less/more than how many seconds? 15 compressions?
• no less than 15 secs and no more than 18 secs • no less than 7 secs and no more than 9 secs
