200,000 People Die Annually From Respiratory Emergencies.
12% of EMS Calls Are For Respiratory Emergencies, 3 Times More Than Heart Attacks.

RESPIRATORY PHYSIOLOGY
- Alveolar / Capillary Exchange
- O2 Rich Air Into Alveoli
- O2 Poor Blood In Capillaries
- CO2 From Capillary to Alveoli
- O2 From Alveoli to Capillary
RESPIRATORY PHYSIOLOGY
- Capillary / Cellular Exchange
- Cells Convert O2 to CO2
- Cell Gives CO2 to Capillary
- Capillary Gives O2 to Cell

INFANTS & CHILDREN
- Leading killer of children

- Rapid deterioration and "crashing" of these patients rapid treatment & assessment is critical!
Causes of Respiratory Distress
- May be result of an acute problem
- Trauma (chest injuries, head injuries)
- Medical condition (heart attack,
allergic reaction, Pneumonia)
- Other conditions (drowning, vomiting)
- Anxiety, stress
- May be a chronic condition
Breathing Difficulty
- Frequent chief complaint.
- May also complain of chest tightness, anxiety, or restlessness.
- Do not rely completely on patients perception, but rather on full patient assessment.
- May be a chronic problem or an acute onset.
Chronic Obstructive Pulmonary Disease (COPD)
- Includes emphysema, chronic bronchitis, and black lung
- Generally affects older patients
- Affects patient continuously
- Causes include cigarette smoking, chemical exposure, and pollution
COPD Chronic Bronchitis
- Inflammation of bronchiole lining
- Produces excess mucus
- Damage or destruction of cilia prevents removal of this mucus
CRACKLES & WHEEZING
- Chronic Bronchitis
- Wheezing From Inflammation
- High Pitch Sound
- Crackles From Mucous
- Wet, Sloppy Sound
COPD Emphysema
- Breakdown of alveoli walls
- Reduces surface area for exchange of oxygen and carbon dioxide
- Reduced elasticity of lungs
ASTHMA
- Episodic disease
- Narrowing of bronchioles & overproduction of mucus
- Typically one directional, allowing air into lungs but requiring forceful exhalation (wheezing)
- Variety of causes
- Allergic reactions
- Pollutants
- Exercise & stress
WHEEZING
- Asthma
- Asthmatic Bronchitis
- Inflammation of the Bronchus and Bronchioles
- Constriction
PNEUMONIA
- Infection of the Lower Airways (Alveoli)
- Sudden Onset of Fever, Chills, Shaking
- Productive Cough w/ Colorful Sputum
- Pain - Aggravated w/ Breathing & Coughing
- Dyspnea w/ Accessory Muscle Use
- Fatigue - Tires Easily
- Lung Sounds - Wheezing, Rales, Rhonchi
MILD CRACKLES - PNEUMONIA
- Expect to Hear the Whole Gamut
- Rales (Fine Crackles)
- Rhonchi (Course Crackles)
- Wheezing
Pulse Oximetry
- If possible, place immediately to obtain "room air" reading.
- Never delay oxygen administration to obtain a reading.
- Normal reading is 95% to 99%
- Below 95% indicates hypoxia
- 91% to 94% = mild hypoxia
- 86% to 90% = moderate hypoxia
- 85% or less = severe hypoxia
Regardless of the reading, ANY patient in distress should receive oxygen.
General Treatment Considerations
- Ensure open airway.
- Jaw-thrust or head-tilt, chin-lift
- Heimlich maneuver as needed.
- Insert oral/nasal airway as needed.
- Suction secretions and fluids as needed.
Providing Artificial Ventilation
Provided through (in order of preference):
- Pocket face mask with
supplemental oxygen
- 2 rescuer bag-valve mask with supplemental oxygen
- Flow-restricted, oxygen-powered ventilation device (FROPVD)
- One rescuer bag-valve mask with supplemental oxygen
ARTIFICIAL VENTILATION
- Adequate Artificial Ventilation
- Chest rises & Falls W/ Each Ventilation
- Sufficient Rate
- Adult 12 / Minute
- Infant & Child 20 / Minute
- Heart Rate Returns to Normal
- Skin Color Improves
ARTIFICIAL VENTILATION
- Inadequate Artificial Ventilation
- Chest Does Not Rise & Fall W/ Each Ventilation
- Rate Too Fast / Too Slow
- Heart Rate Does Not Return to Normal
- Skin Color Does Not Improve

- Increased Pulse Rate
- Nervousness
- Tremors
RESPIRATORY EMERGENCY
- Re-Assessment Strategy
- Monitor Vital Signs
- On-Going Assessment
- Respiratory Patients Can Deteriorate Rapidly
REMEMBER
NO AIRWAY + NO O2 = DEATH !
PEDIATRIC CONSIDERATIONS
- Inhalers Are Common For Kids
- Use Same Criteria as With Adults
- Retractions Are More Common In Kids
- Children Compensate Very Well to the Point of Death
- Cyanosis Is A Late Sign
- Upper Airway Compromise Due to Illness is Common Funny Breathing Sounds
- Frequent Coughing Instead of Wheezing ?
