ABCD’s
• AIRWAY
• BREATHING• CIRCULATION
• DEFIBRILLATION
• SEVERE BLEEDING
![Page 3: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/3.jpg)
The Breathing Process• Air (oxygen) into nose and
mouth---passes through pharynx----travels through the trachea--- lungs---blood---delivered to brain, organs, muscles (provides energy)
![Page 4: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/4.jpg)
BRAIN and OXYGEN
• Brain is very sensitive to oxygen starvation
• Brain cells start to die in 4-6 minutes without oxygen
![Page 5: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/5.jpg)
TIME FRAME• 0 minutes: breathing stops,
heart will soon stop beating• 4-6 minutes: brain damage
possible• 6-10 minutes: brain damage
likely• Over 10 minutes: irreversible
brain damage certain
![Page 6: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/6.jpg)
BREATHING• Brain controls breathing
• Adjusts rate and depth of breaths based on O2 and CO2 levels
• Requires respiratory, circulatory, nervous, and musculoskeletal systems to work together
![Page 7: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/7.jpg)
BREATHING EMERGENCIES• An obstructed airway (choking)• Illness, such as pneumonia• Respiratory conditions (asthma, emphysema)• Electrocution• Shock• Drowning• Heart attack or heart disease• Chest or lung injury• Allergic reactions (food, insects)• Drugs• Poisoning• Hyperventilation
![Page 8: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/8.jpg)
RESPIRATORY DISTRESS
• Most common type of breathing emergency
• Injury
• Illness
• Excitement
• Anxiety
![Page 9: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/9.jpg)
SIGNS and SYMPTOMS--RD
• Obvious
• Cannot catch their breath or gasp for air
• Grunting, wheezing, gurgling, shrill sounds
• Breaths unusually fast, slow, deep, or shallow
• (slow= less than 8 breaths per minute)
![Page 10: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/10.jpg)
S/S Respiratory Distress
• Skin
• Unusually moist and flushed
• Pale, ashen, or bluish (cyanosis)
• Symptoms
– Dizzy, lightheaded, painful, tingling in lips, hands, or feet
![Page 11: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/11.jpg)
Specific Types of RD
• Asthma
• Emphysema
• Hyperventilation
• Anaphylaxis
![Page 12: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/12.jpg)
Care for RD• Initial assessment• Summon EMS• Help the victim rest comfortably• Physical exam• SAMPLE history• Reassure the victim• Assist with medication• Monitor vital signs
![Page 13: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/13.jpg)
RESPIRATORY ARREST
• Breathing stops
–Illness
–Injury
–Obstructed airway
*heart will stop beating, organs will begin to fail
![Page 14: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/14.jpg)
RESCUE BREATHING
• Breathing air into a person to supply him or her with the O2 needed to survive
![Page 15: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/15.jpg)
STEPS
• Determine LOC—unresponsive
• Open airway and look, listen, feel for breathing
• No breathing
–Give 2 slow breaths
–Check for pulse
–Look for severe bleeding
![Page 16: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/16.jpg)
RESCUE BREATHING
• Keep airway open
• 1 breath every 5 seconds
• Every minute re-check pulse
![Page 17: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/17.jpg)
When to stop rescue breathing:• Victim breathes on own
• Victim has no pulse—CPR
• Someone with more training than you arrives
• You are too exhausted to continue
• The scene becomes unsafe
![Page 18: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/18.jpg)
Special considerations:
• Air in stomach
• Vomiting
• Mouth-to-nose breathing
• Mouth-to-stoma breathing
• Victims with dentures
• Suspected spine injury
![Page 19: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/19.jpg)
Infants and Children• Faster breath rate and pulse rate
than adults• Rescue breaths are faster• Less air in each breath• Head-tilt is less• Cover mouth and nose
• Infants: 1 breath every 3 seconds• Children: 1 breath every 5 seconds
![Page 20: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/20.jpg)
AIRWAY OBSTRUCTIONS
• Most common cause of respiratory emergency
• TWO causes: anatomical or mechanical
• Partial or Complete
![Page 21: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/21.jpg)
PARTIAL AIRWAY OBSTRUCTION• Can still move some air in and out
of the lungs• Person can still cough and/or speak• Person may clutch throat (universal
sign)
• Encourage them to keep coughing and summon EMS if it continues
![Page 22: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/22.jpg)
COMPLETE AIRWAY OBSTRUCTION• Unable to speak, cough, cry,
or breathe
• CALL 911
• Heimlich Maneuver/ Abdominal thrusts until the obstruction is clear (or they become unconscious)
![Page 23: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/23.jpg)
Unconscious Choking Adult/Child• Lay the person down1. Open the airway by lifting the jaw
up2. Finger sweep3. Open the airway—head-tilt/chin-lift4. Give 2 slow breathsIf air does not go in:5. Reposition (retilt) the head6. Give 2 slow breaths
![Page 24: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/24.jpg)
If air still does not go in:
7. Give up to 5 abdominal thrusts or chest thrusts**
8. Do a finger sweep
9. Give 2 slow breaths (reposition if necessary)
Repeat until object is expelled
![Page 25: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/25.jpg)
Chest Thrusts
• Middle of the sternum
• Person is too large or they are pregnant
• Compress 1 ½ to 2 inches
• 5 quick thrusts
![Page 26: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/26.jpg)
Conscious Choking Infant• Call 911
• Alternate 5 back blows and 5 chest thrusts until the object comes out
![Page 27: BREATHING EMERGENCIES](https://reader035.vdocuments.us/reader035/viewer/2022062518/5681474a550346895db48a75/html5/thumbnails/27.jpg)
Unconscious Choking Infant
1. 2 slow breaths (they don’t go in)2. Reposition head3. 2 more slow breaths (if they don’t go in,
assume airway is obstructed)4. Give 5 back blows5. Give 5 chest thrusts6. Do a foreign body check7. Open the airway8. Give 2 slow breaths (if they don’t go in,
repeat steps)
