A

ventilation

21
Q

ABCs

CABs

A

Airway, breathing, circulation

Circulation/compressions, airway, breathing

25
Q

CPR steps:

A
  1. Restore circulation (chest compressions)
  2. Open the airway
  3. Restore breathing (provide rescue breathing)
26
Q

System Components of CPR

A 
Recognition/Activation of EMS
Immediate high quality CPR
Rapid defibrilation
Basic and advanced EMS
ALS and postarrest care
27
Q

AHA’s chain of survival

A

Recognition and activation of the emergency response system
Immediate, high-quality CPR
Rapid defibrillation
Basic and advanced emergency medical services
Advanced life support and post-arrest care
If any are missing, the patient is likely to die

28
Q

Although cardiac arrest in adults usually occurs before respiratory arrest, the reverse is true for __________

A

infants and children.

29
Q

CPR protocol for Children

A

Apply after first five cycles of CPR.
Manual defibrillator preferred for infants 1 month to 1 year
If unavailable, use pediatric-sized pads and dose-attenuating system.
If neither is available, then use an AED with adult-sized pads with anterior-posterior placement.

30
Q

Special situations (contraindications of AED)

A

Pacemakers and implanted defibrillators
Wet patients
Transdermal medication patches

31
Q

For CPR to be effective, patient must be _____ on firm, flat surface. _____ patient onto __________

A

supine
Log roll
long backboard.

32
Q

If you determine that the patient is adequately breathing, and there are no signs injury to the head, spine, hip, or pelvis, what should you do?

A

Place the patient in the recovery position. This maintains clear airway, allows vomitus to drain from mouth, roll the patient as a unit.

33
Q

What is the rate of compressions and ventilation for a single rescue CPR with 1 EMT?

A

30:2

34
Q

With two EMS CPR, how often should you switch duties?

A

35
Q

Cardiac arrest in infants and children ______ respiratory arrest.

A

follows

Airway and breathing are the focus of pediatric BLS.

36
Q

Causes of child respiratory problems:

A 
Injury
Infections
Foreign body
Submersion
Electrocution
Poisoning/overdose
SIDS
37
Q

Infant and Child CPR
Not breathing and has a pulse: _______________

Not breathing and no pulse:_____________

A

1 breath every 3 to 5 seconds

2 breaths after every 30 compressions

38
Q

Chest compression fraction: The total percentage of time during a resuscitation attempt in which chest compressions are being performed should be

A

at least 60%

39
Q

Contraindications of CPR

If the scene is not safe
If the patient has obvious signs of death
Rigor mortis (stiffening of body)
Dependent lividity (livor mortis)
Putrefaction or decomposition of body
Evidence of nonsurvivable injury
DNR orders
40
Q

Once you begin CPR, continue until (STOP acronym):

A

S Patient Starts breathing and has a pulse
T Patient is Transferred to another provider of equal or higher-level training
O You are Out of strength
P Physician directs to discontinue

41
Q

Airway obstruction in adults may be caused by:

A 
Relaxation of throat muscles
Vomited or regurgitated stomach contents
Blood
Damaged tissue
Dentures
Foreign bodies
42
Q

Abdominal-thrust maneuver (Heimlich) is recommended in ______________________

A

responsive adults and children older than 1 year.

43
Q

Instead of abdominal-thrust maneuver, use chest thrusts for the following responsive patients

A

Women in advanced stages of pregnancy

Obese patients

44
Q

When do you aply an EAD on a child?

A

After 5 cycles of CPR

45
Q

Devices and techniques to assist circulation

A 
Active compression-decompression CPR
Impedance threshold device (ITD)
Mechanical piston device
Load-distributing band CPR or vest CPR
Manual chest compressions remain the standard of care.
46
Q

Foreign Body Airway in Infants

A

Instead, perform back slaps and chest thrusts (compressions).
