| Question | Answer |
|---|---|
| If no pulse, start cycles of ___ compressions and __ breaths | 30; 2 |
| What rate of compressions should you use? | Push hard and fast (downward 1.5-2 inches) at a rate of 100 per minute |
| ABCD | Airway, Breathing, Circulation, Defibrillation |
| Caution: Things to Avoid with Head Tilt-Chin lift | Do not press deeply into the soft tissue under the chin b/c this may obstruct the airway, do not use thumb to lift chin, do not close victim's mouth completely (unless using mouth-to-nose breathing) |
| The rescuer's exhaled air contains approximately ___ oxygen and ___ carbon dioxide. | 17%; 4% This is enough oxygen to supply the victim's needs |
| How long should you give 1 breath to the victim? | 1 second long breaths |
| If you give breaths too quickly or with too much force, air is likely to enter the _____ than the lungs | stomach. This can cause gastric inflation. This may result in vomiting, aspirations, or pneumonia. To prevent Gastric inflation: take 1 second to deliver each breath, and deliver enough air to make the victim's chest rise |
| Two Rescuers should use a compression-ventilation ratio of __ compressions to __ breaths when giving CPR to children and infants | 15 compressions to 2 breaths |
| In 1-rescuer CPR, if you have already shouted for help (step 1), activated the emergency response and gotten an AED if available (step 2), and opened the victim's airway to check breathing for at least 5 seconds (step 3), what is the next step? | 4. If no adequate breathing, give 2 breaths. 5. Check the victim's pulse (5-10 seconds) 6. If you do not definitely feel a pulse, perform 5 cycles of compressions and ventilations (30:2 ratio) |
| If after your first 2 breaths that you give to a victim, you check the pulse (5-10 seconds) and you feel a pulse, what do you do next? | Give 1 breath every 5-6 seconds and recheck their pulse every 2 minutes |
| Which pulse should be used to monitor an adult? | Carotid pulse on the side closest to you |
| Limit chest compression interruptions to ___ seconds, except for intubation, defibrillation, or moving the victim from danger (such as a fire) | 10 seconds |
| CPR guidelines for children should be used until | puberty. Signs of puberty for females: breast development; in males: underarm, chest and facial hair |
| Depth of compressions in child age 1-puberty | Press down 1/3-1/2 the depth of the chest with each compression (adult - press down 1.5-2 inches with each compression) |
| How much time should you take to measure a pulse? | Take at least 5 seconds, and no more than 10. If a child's HR is less than 60 beats/min with signs of poor perfusion (eg, poor color), start CPR |
| Rescuers in the out-of-hospital setting should provide about ___ cycles of CPR for a child before using an AED | 5 |
| In children, you made need to try more than once to open the airway and give __ breaths | 2. (in adults, you just need to try this once) |
| In child age 1 to puberty, if after giving 2 breaths you feel a definite pulse, the next step is | give 1 breath every 3 seconds,s recheck pulse every 2 minutes |
| For child age 1 to pubery, what compression rate should be used, and what compression:breath ratio is used? | 100 compressions/minute=rate, 30compressions:2 breaths |
| These devices are the most common method of providing positive pressure ventilation in the out-of-hospital and in-hospital settings | Bag mask devices. Use the E-C clamp technique and deliver breaths for 1 second each. |
| At times, patients will have inadequate breathing or no breathing, but will have a pulse. For these victims, rescuers will give breaths with ________. | Compressions. This is called rescue breathing. |
| Delivering too many breaths per minute can cause | hyperventilation which may worsen the outcome of cardiac arrest. It can decrease venous return to the heart and reduce blood flow during chest compressions |
| IN 2-rescuer CPR for adults and children, what is the compression:ventilation ratio? | Adults: 30:2, Children: 15:2 |
| Use AEDs only when victims have all 3 of these clinical findings: | no response, no breathing, no pulse |
| When should child AED pads be used? | For children less than 8 years old only. |
| After the AED delivers a shock to the victim, what is your next step? | Continue CPR starting with compressions. Don't check pulse |
| What adjustment do you make when using an AED in a patient with an implanted defibrillator/pacemaker? | Place the AED electrode pad at least 1 inch to the side of the implanted device |
| True or False: you can use adult AED pads on a child if child pads are not available. | True, as long as the pads can be placed without touching each other |
| The infant BLS sequence is | ABC- Airway, Breathing, Circulation |
| Where should compressions be performed on infants? | Draw an imaginatry line between the nipples. Place 2 fingers just below this line. This will allow you to compress on te lower half of the breast bone. Do not press on the xiphoid process |
| Which is the preferred breathing technique in infants? | Mouth-to-mouth-and-nose |
| In infants, what is the compression rate and compression: ventilation ratio? | Compression rate of 100/min. 1 rescuer - 30:2, 2 rescuers - 15:2 |
| Where do you perform a pulse check in an infant? | Brachial pulse. (on the inside of the upper arm, midway between the infant's elbow and shoulder). |
| Rescue breathing in infants | Give 1 breath every 3 to 5 seconds. Check the pulse every 2 minutes |
| What is the preferred hand technique for 2-rescuer infant CPR? | 2 thyumb-encircling hand technique |
| Responsive Choking Victim | Procede with Heimlich maneuver |
| Unresponsive Choking Victim | Procede with CPR |
| True or False: A choking victim can always cough forcefully | F. Only in mild aiway obstruction. If severe, they may have a weak, inffective cough or no cough at all |
| Finger sweeps in choking infants | Do not perform blind finger sweeps in infants and children because the foreign body may be pushed back into the airway, causing further obstruction or injury |
| For a responsive choking infant, use _____ and _____ to try to remove the airway obstruction | 5 black slaps followed by 5 chest thrusts |
| When is cricoid pressure used? | Only in unresponsive patients. It is effective for preventing gastric inflation during positive pressure ventilation. |
| In a victim with suspected cervical spine injury use which technique for obtaining an open airway? | Jaw thrust. |
| Agonal gasps may occur early in | cardiac arrest. They do not constitute adequate breathing |
