What is the maximum amount of time you should take to check for a carotid pulse?
10 seconds<\/p>\n\n\n\n

When should you initially ensure that the scene is safe?
When I first see a potential victim
Always make sure the scene is safe before approaching<\/p>\n\n\n\n

Which victim requires CPR?
A victim who is unresponsive with no normal breathing and no pulse
A victim who is unresponsive but is breathing adequately
A victim with a pulse who is having trouble breathing
A victim with chest pain and indigestion
A victim who is unresponsive with no normal breathing and no pulse
check for 10 seconds if no pulse and no breathing, start CPR<\/p>\n\n\n\n

What is a pocket mask?
a mask that is placed over the nose\/mouth with a 1 way valve<\/p>\n\n\n\n

What is a bag mask<\/p>\n\n\n\n

How to initiate use of a pocket mask
cover nose\/mouth by R hand over top & L hand holding it to chin
head tilt, chin lift<\/p>\n\n\n\n

Opening the airway for mask ventilation
Place one hand on the forehead
Push with your palm to tilt the head back
Place the fingers of the other hand on the bony part of the chin
Lift the jaw to bring the chin forward
Place the pocket mask on the victim’s face, using the bridge of the nose as a guide
Seal the pocket mask against the face (Push down hard)
While you lift the jaw and the mask is sealed, give 2 breaths
Deliver each breath over 1 second, enough to make the victim’s chest rise<\/p>\n\n\n\n

Using your pocket mask to open the airway and give 2 breaths (as seen below), What should you observe when trying to determine if breaths for a victim are effective?
Visible rise of the chest with rescue breath (s)<\/p>\n\n\n\n

What is the best way to open the airway of an unresponsive victim with no suspected neck injury?
Use the tongue lift-finger sweep
Use the head tilt-chin lift
Use the head tilt only
Use a mask
head tilt – chin lift
Opening the airway and getting the tongue out of the way<\/p>\n\n\n\n

Universal steps for using an AED
Open the carrying case. Power on the AED
Follow the AED prompts as a guide to next steps (audio prompts)
Attach AED pads to the victim’s bare chest
Clear the victim and allow AED to analyzes the rhythm
If AED advises a shock, clear the victim, loudly state “Everybody clear”
Press the shock button
The shock will produce a sudden contraction of the victim’s muscles.
If no shock is needed, and after any shock delivered, immediately resume 2 minutes of CPR, starting with chest compressions
Every 2 minutes of CPR, the AED will prompt you to repeat the steps above.<\/p>\n\n\n\n

Steps !!
assess for safety
check fo response
activate emergency response
begin chest compressions
deliver ventilation
set up AED<\/p>\n\n\n\n

X
rate
depth
chest depression<\/p>\n\n\n\n

What should you do after the AED delivers a shock?
Immediately restart CPR, beginning with chest compressions.
as soon as the shock is complete perform chest compressions until the AED returns in 2 minutes.<\/p>\n\n\n\n

As soon as an AED becomes available, which of the following is the first step you should perform to operate the AED?
Turn on the AED to follow the prompts<\/p>\n\n\n\n

When the AED analyzes it prompts “no shock advised,” what is your immediate next action?
Resume high quality CPR for 2 minutes
No Shock Advised means the patient is not in our shockable rhythms and you should continue CPR immediately.
DO NOT REMOVE PADS<\/p>\n\n\n\n

If the AED advises a shock, what are your next actions?
Clear the victim, when everyone is clear the AED operator presses the flashing shock button
its very important to clear the victim to make sure nobody is in contact with the victim, when everyone is clear you can hit the flashing shock button. This is the highest chance of survival.<\/p>\n\n\n\n

Special Circumstances for AED
Victim has a hairy chest, you would need to dry shave the area where you will place the pads
Water on the victims chest is a good conductor of electricity, you need to wipe the chest before attaching the AED (it doesn’t need to be completely dry)
NO LAYING IN WATER
Implanted Defibrillators\/Pacemakers – Avoid placing the AED pads directly over this implanted devise. Place the pads an inch lower.
Transdermal Medication Patches – If it does not delay delivery of a shock, remove the patch and wipe the area before attaching the AED pads.<\/p>\n\n\n\n

What rate are you compressing ?
100-120 \/ minute
2-2.4″ or 5 cm deep<\/p>\n\n\n\n

When should you deliver a shock from the AED?
After the AED advises a shock, charges, states a “clear the victim” message, and prompts me to push the SHOCK button<\/p>\n\n\n\n

The proper steps for operating an AED are:
Power on the AED, attach electrode pads, shock the individual, and analyze the rhythm
Power on the AED, attach electode pads, analyze the rhythm, clear the individual, and deliver shock
Attach electrode pads, check pulse, shock individual, and analyze rhythm
Check pulse, attach electrode pads, analyze rhythm, shock patient
Power on the AED, attach electode pads, analyze the rhythm, clear the individual, and deliver shock<\/p>\n\n\n\n

What should you do before the AED analyzes the rhythm?
Ensure that no one, including you, is touching the patient
to properly detect the patients rhythm, nobody should be touching the patient including doing CPR. The AED will prompt you on the next steps, either shock or no shock.<\/p>\n\n\n\n

T\/F: AED pad placement is either upper right and lower left OR anterior posterior.
True<\/p>\n\n\n\n

Bag-Mask Ventilation Technique Key Concepts
Position yourself directly above the victim’s head
Place the mask on the victim’s face, using the bridge of the nose as a guide for correct position.
Use the E-C clamp technique to hold the mask in place while you lift the jaw to hold the airway open
Perform head tilt
Place the mask on the victim’s face, with the narrow portion at the bridge of the nose
Use the thumb and index finger of one had to make a “C” on the side of the mask, pressing the edges of the mast to the face
Use the remaining fingers to lift the angle of the jaw, open the airway and press the face to the mask
Squeeze the bag and give breaths (1 second each) while watching for chest rise.<\/p>\n\n\n\n

What is likely to cause air to enter the victim’s stomach (gastric inflation) during bag-mask ventilation?
Breaths are given too quickly or with too much force
can cause vomiting or gastric —<\/p>\n\n\n\n

Which of the following devices or techniques is recommended for a team rescuer to provide breaths during CPR?
Bag-mask device (BVM or Ambu Bag)
BVM or Ambu Bag is the most common device used in pre-hospital and hospital settings for cardiac arrest.<\/p>\n\n\n\n

to properly ventilate a patient with a BVM you perform at head-tilt chin-lift, use the thumb and index finger to make a “C” on the side of the mask, pressing the edges of the mask to the face. Squeeze bag and give breaths over 1 second.
True pg 26 in BLS manual<\/p>\n\n\n\n

2 rescuer CPR
RESCUER 1 performs compressions at a rate of 100 to 120\/min, compresses 2 inches and compresses at 30 compressions
RESCUER 2 performs maintains an open airway using the head tilt-chin lift and gives breaths while watching for chest rise<\/p>\n\n\n\n

To start CPR you place the heal of your hand in the center of the chest (as seen below) with your arms straight. What is the recommended depth of chest compressions for an adult victim?
at least 2 inches<\/p>\n\n\n\n

In performing 2 rescuer CPR on an adult victim (as seen below), What is the compression-ventilation ratio for 2-rescuer adult CPR?
30:2<\/p>\n\n\n\n

What is the recommended rate for performing chest compressions for victims of all ages?
100-120 compressions per minute<\/p>\n\n\n\n

Why is it important to compress to the appropriate depth during CPR?
Adequate depth of compression is needed to create blood flow during compressions.<\/p>\n\n\n\n

What to communicate during team CPR
ask for observations about possible oversights
allocate duties<\/p>\n\n\n\n

closed loop communication
Sender has a request
Repeated by the person helping
Sender states “yes” or “no” in order to proceed<\/p>\n\n\n\n

6 roles for CPR
compression -timing compression\/breath
AED operation (alternates w original compressor)
Team leader – makes treatment decisions & quality control
timer\/recorder – logs interruptions and compression change
IV\/medications<\/p>\n\n\n\n

      Tap the child’s shoulders
      If the victim is not responsive, shout for nearby help
      Activate the emergency response system or code
      Assess for breathing and carotid pulse for 10 seconds
      If no pulse and no breathing, Start CPR
      Sent someone to get the AED (if available) if not wait for 911
      If the pulse of a child is less then 60bbp with signs of poor perfusion start CPR
      If alone (waiting for help), start 30 compressions to 2 breaths
      If working as a team, start 15 compressions to 2 breaths
      Switch compressor roles every 2 minutes
      Once the AED arrives use it immediately<\/p>\n\n\n\n

      What should you do when a child victim has a pulse of more than 60\/min but is not breathing?
      Give breaths without chest compressions.
      the child is in respiratory arrest (not cardiac arrest), just breath for him once every 3-5 seconds.<\/p>\n\n\n\n

      What is the compression-ventilation ratio for 2-rescuer child CPR?
      15:2 !!!<\/p>\n\n\n\n

      If the victim is not responsive, shout for nearby help
      Activate the emergency response system or code
      Assess for breathing and brachial pulse for 10 seconds (do not check the neck for a pulse, the neck is under developed)
      If no pulse and no breathing, Start CPR
      Sent someone to get the AED (if available) if not wait for 911
      If the pulse of an infant is less then 60bbp with signs of poor perfusion start CPR
      If alone (waiting for help), start 30 compressions to 2 breaths
      If working as a team, start 15 compressions to 2 breaths
      Switch compressors every 2 minutes
      If the AED arrives, use is immediately<\/p>\n\n\n\n

      What is the recommended depth of compressions for an infant victim for 1 rescuer CPR
      At least one third the depth of the chest, approximately 1.5 inches (4 cm)<\/p>\n\n\n\n

      How does complete chest recoil contribute to effective CPR on an infant?
      Allows the heart to refill with blood between compressions
      allow the chest to come up completely to allow blood to refill chambers of the heart.<\/p>\n\n\n\n

      You find a child that is unresponsive. After yelling for help, you check and find the child is not breathing and no pulse. What is the next step?
      go right into compressions
      Deliver 30 chest compressions<\/p>\n\n\n\n

      what is the recommended place to check an infants pulse?
      brachial pulse (elbow)<\/p>\n\n\n\n

      witness collapse = activate emergency response & get AED
      no witness collapse = immediately start CPR<\/p>\n\n\n\n

      how to perform infant CPR
      first 2 fingers \u2026 NOT ON BREAST BONE
      compress 1.5 inches
      100-120 compressions per minute
      allow full recoil<\/p>\n\n\n\n

      infant bag mask technique
      correct mask size
      chest rise is most observable sign of breath effectiveness
      EC clamp technique
      do NOT tilt past normal infant neck position or airway can become BLOCKED<\/p>\n\n\n\n

      What is the preferred technique for providing chest compressions during 2-rescuer CPR for an infant?
      The 2 thumb-encircling hands technique
      encircle your hands with thumbs on the lower part of the breast bone.<\/p>\n\n\n\n

      Why are chest compressions important on an infant in cardiac arrest?
      pump blood to the rest of the body
      compressions pumps blood to vital organs<\/p>\n\n\n\n

      how do you hold your hands for 2 rescuer CPR for an infant and the proper compression to ventilation ratio?
      2 Thumbs-encircling hands technique at a compression:ventilation ratio of 15:2<\/p>\n\n\n\n

      What size AED pads should be used for a child less than 8 years of age?
      Adult pads\/dose may be used if pediatric pads\/dose attenuator are not available.<\/p>\n\n\n\n

      When checking a pulse on an infant, where is the brachial pulse located?
      On the inside of the upper arm, between the elbow and the shoulder
      do not check the Carotid artery for an infant, check the brachial pulse<\/p>\n\n\n\n

      You are treating a pediatric cardiac arrest patient. Where do you place the AED pads on an infant\/child?
      chest nd back<\/p>\n\n\n\n

      how to give mouth to mouth WITHOuT barrier
      For Adults and Children, Pinch the nose close with your thumb and index finger, open airway and provide 2 breaths over 1 second each.
      For infants (less then a year of age) give Mouth-to-Mouth and Nose. Place your mouth over the infant’s mouth and nose and create an airtight seal and give 2 buffs just enough to make the chest rise.
      Rescue breathing is giving breaths to an unresponsive victim who has a pulse but is not breathing. The victim will be alive, but not breathing in respiratory arrest (not cardiac arrest). For respiratory arrest for adults, give 1 breath every 5-6 seconds. For infants and children give 1 breath every 3-5 seconds. Check the pulse every 2 minutes to make sure it remains. If you lose a pulse, start CPR.<\/p>\n\n\n\n

      To give mouth to mouth to an adult\/child victim, you would?
      Pinch off the nose and cover your mouth with the victims mouth and give 2 breaths<\/p>\n\n\n\n

      When doing mouth-to-mouth breathing for an infant, it is acceptable to cover the babies mouth and nose with your mouth to form an airtight seal?
      Correct, the Mouth to Mouth&Nose breaths are the most effective for a baby in cardiac arrest.<\/p>\n\n\n\n

      adult\/child choking
      Stand or kneel behind the victim and wrap your arms around the victim’s waist.
      Make a fist with one hand
      Place the thumb side of your fist against the victim’s abdomen, in the midline, slightly above the navel and well below the breastbone and give forceful upward thrust.
      Repeat thrust until the object is expelled, or the victim becomes unresponsive.
      If the victim becomes unresponsive, lower the victim to the floor, begin CPR with one exception. Each time you open the airway to give breaths, look for the object. If you can see it try to remove it. Do not perform a blind finger sweep. Repeat sequence until airway is patent.<\/p>\n\n\n\n

      If a victim of foreign-body airway obstruction becomes unresponsive, after you send someone to activate the emergency response system, what is the next recommended action?
      Start CPR then look in the mouth to see if you see an object, if not provide 2 breaths and repeat until object is clear.<\/p>\n\n\n\n

      `What is the best way to relieve severe choking in a responsive adult or child?
      perform the abdominal thrusts (heimlich) until the object is out or until the victim becomes unresponsive<\/p>\n\n\n\n

      If the victim is pregnant or obese and you can’t wrap your arms around to perform the Heimlich maneuver, perform chest thrusts instead of abdominal thrusts as shown in the picture below.
      perform chest thrusts instead of abdominal thrusts in a pregnant or obese choking victim.<\/p>\n\n\n\n

      baby choking
      Hold in the infant facedown,
      Deliver up to 5 back slaps forcefully between infant’s shoulder blades, then turn the infant over and provide up to 5 quick downward chest thrusts (same location as you would for CPR)
      Repeat the sequence of up to 5 back slaps and up to 5 chest thrusts until the object is removed or the infant becomes unresponsive.
      If the infant becomes unresponsive, place the infant on a hard flat surface, begin CPR with one exception. Each time you open the airway to give breaths, look for the object. If you can see it try to remove it. Do not perform a blind finger sweep. Repeat sequence until airway is patent.<\/p>\n\n\n\n

      What is the best action to relieve severe choking in a responsive infant?
      5 back slaps and 5 chest thrusts until the object comes out or until the infant loses consciousness.<\/p>\n\n\n\n

      only sweep for object\u2026
      if you can see it!!<\/p>\n\n\n\n

      ADVANCED airway
      CONTINUOUS compressions (not stopping except to switch CPR compressors) and you will ventilate 1 breath every 6 seconds via a bag valve mask
      helps oxygenation to tissues stay high<\/p>\n\n\n\n

      opioid related life threatening emergency
      If you suspect an Opioid overdose, check to see if victim is unresponsive and has a pulse and\/or breathing
      If the victim is breathing normally and a pulse is present you can monitor for responsiveness, breathing and pulse.
      If the victim is not breathing normally but a pulse is present. Provide rescue breathing at 1 breath every 5-6 seconds. Administer naloxone per local protocols and monitor for response.
      If the victim is not breathing and no pulse is present. Start CPR and get the AED as soon as possible. Administer naloxone per local protocols and monitor for response.<\/p>\n\n\n\n

      What are the correct compression and ventilation rates for 2-rescuer CPR in the presence of an advanced airway in an adult victim?
      100-120 compressions w breath every 6-8 seconds<\/p>\n\n\n\n

      Naloxone (Narcan) via the IV or Nasal route can be used to reverse the effects of opioids and help to restore breathing\/Pulse in a cardiac arrest?
      Naloxone (Narcan) should be given during CPR if you suspect an opioid based cardiac arrest.<\/p>\n\n\n\n

      chance of survival with the AED shock
      70%<\/p>\n\n\n\n
