CPR AND BREATHS WITH AN ADVANCED AIRWAY
Question Answer
What do advanced airways prevent?they prevent airway obstruction
What do advanced airways provide?a route for more effective oxygenation and ventilation
List examples of advanced airways?1) laryngeal mask airway 2) supraglottic airway device 3) endotracheal tube
If NO advanced airway in place (just using mouth-to-mouth, bag-mask device or pocket mask), what is the compressions rate and compression to breath ratio for adults? For child and infants?1) compression rate of 100-120 / min and a compression to breath ratio of 30 compressions to 2 breaths 2) compression rate of 100-120 / min and a compression to breath ratio of 30 to 2 with one rescuer and 15 to 2 with two rescurers
If an advanced airway is in place, what is the compression to breath rate and ratio for adults? for child and infants?1) it is the same for both adults and child and infants as follows = compression rate of 100-120 / min 2) continuous compressions WITHOUT pauses for breaths 3) one breath EVERY 6 seconds (10 breaths per minute) for adults, children and infants

RESCUE BREATHING:
Question Answer
Define rescue breathing? it is giving breaths to an unresponsive victim who HAS a pulse but is NOT breathing
How may you provide rescue breathing?1) using barrier devices (pocket mask) or bag-mask device 2) if emergency equipment is not available, use mouth-to-mouth or mouth-to-mouth-and-nose technique
Describe the rescue breathing for adults?1) give 1 breath every 5-6 seconds for about 10-12 breaths per minute 2) give each breath in 1 second 3) each breaths should result in visible chest rise 4) check the pulse about every 2 minutes
Describe the rescue breathing for infants and children?1) give 1 breath every 3-5 seconds (12-20 breaths per minute) 2) give each breath in 1 second 3) each breaths should result in visible chest rise 4) check the pulse about every 2 minutes
memorize
WHEN TO START CPR IN AN INFANT OR A CHILD WHEN PROVIDING RESCUE BREATHING:
Question Answer
When do you start CPR in an infant or child when providing rescue breathing?if you notice signs of poor perfusion in an infant despite adequate rescue breathing (that is, despite effective oxygenation and ventilation) and the HR is < 60.
memorize
RESPIRATORY ARREST:
Question Answer
When does respiratory arrest occur?1) when normal breathing stops preventing oxygen supply and carbon dioxide exchange
Lack of oxygen to the brain causes what?a person to become unresponsive
If the lack of oxygen to the brain is not treated immediately, what happens?brain injury, cardiac arrest and death
Give an example of a respiratory arrest that is potentially reversible?1) opioid overdose (which causes unresponsiveness, respiratory depression and respiratory arrest)
What are the s/s to identify respiratory arrest?1) unresponsive person 2) not breathing or only gasping for air 3) still has a PULSE
memorize
TECHNIQUES FOR GIVING BREATHS WITHOUT A BARRIER DEVICE
MOUTH-TO-MOUTH BREATHING FOR ADULTS AND CHILDREN:
Question Answer
List the 7 steps of providing mouth-to-mouth breathing for adults and children?1) hold the victim's airway open with a head tilt-chin lift 2) pinch the nose closed with your thumb and index finger using the hand on the forehead 3) take a regular (not deep) breath and seal your lips around the victim's mouth, creating an airtight seal 4) deliver 1 breath over 1 second. Watch for the chest to rise as you give the breath 5) if the chest does NOT rise, repeat the head tilt-chin lift 6) give a second breath (blow for about 1 second). Watch for the chest to rise 7) if you are unable to ventilate the victim after 2 attempts, promptly return to chest compressions
memorize
BREATHING TECHNIQUES FOR INFANTS:
Question Answer
What 2 techniques are used to give breaths to infants?1) mouth-to-mouth-and nose 2) mouth-to-mouth
Which of the above 2 techniques is preferred for infants?mouth-to-mouth-and-nose technique (however if can't cover the infant's nose and mouth with your mouth, use the mouth-to-mouth technique instead)
List the steps for mouth-to-mouth-and nose technique?1) maintain a head tilt-chin lift to keep the airway open 2) place your mouth over the infant's mouth and nose and create an airtight seal 3)blow into the infants nose and mouth (pausing to inhale between breaths) just enough to make the chest rise with each breath 4) if the chest does not rise, repeat the head tilt-chin lift to reopen the airway and try to give a breath that makes the chest rise. It may be necessary to move the infant's head through a range of positions to provide effective breaths. When the airway is open, give breaths that make the chest rise
List the steps for mouth-to-mouth technique?1) maintain a head tilt-chin lift to keep the airway open 2) pinch the victim's nose tightly with thumb and forefinger 3) make a mouth-to-mouth seal 4) deliver each mouth-to-mouth breath, making sure that the chest rises with each breath 5) if the chest does NOT rise,, repeat the head tilt-chin lift to reopen the airway. It may be necessary to move the infant's head through a range of positions to provide effective breaths. When the airway is open, give breaths that make the chest rise
memorize
RISK OF GASTRIC INFLATION:
Question Answer
What maneuvers can cause air to enter the stomach rather than the lungs? What will this lead to?1) giving breaths too quickly or with too much force 2) gastric inflation
Define gastric inflation?filling of the stomach with air
List the 3 types of rescue breathing manuevers that gastric inflation frequently occurs in?1) mouth-to-mouth 2) mouth-to-mask 3) bag-mask ventilation
How can rescuers reduce the risk of gastric inflation?1) avoiding giving breaths too rapidly 2) avoid giving breaths too forcefully 3) avoid giving breaths with too much volume
Can gastric inflation still develop even though rescuers give breaths correctly?yes
List 2 ways that the risk of gastric inflation can be reduced?1) deliver each breath over 1 second 2) deliver just enough air to make the victim's chest rise
memorize
