Differential Diagnosis of Dyspnea
• In disease states the cause is usually a result of cardiac,
pulmonary pathology or trauma
• Severe dyspnea is a medical emergency if not treated
appropriately respiratory failure and death can occur
• When eliciting a history it is helpful to determine if the
dyspnea is acute or chronic utilizing
– Sample
– OPQRST

– Inspiratory stridor
– Cyanosis, drooling
– Nasal flaring
– Tachypnea
– Retractions
– Poor air entry on auscultation

Upper Airway
• Noisy breathing:
– Snoring: Indicates partial obstruction of the upper airway that
causes a vibration of air as it passes thru the nasopharynx and
oropharynx (tongue)
– Stridor: A harsh, continuous crowing sound. Mostly occur
during inspiration
![Page 18: Region VIII EMS Systems July 2016 Version July 2016 Dyspnea .pdf · respiratory distress • Provides earliest, most accurate indication of respiratory distress • Changes in capnography](https://reader033.fdocuments.net/reader033/viewer/2022041618/5e3d042cb3d7a473077ef968/html5/thumbnails/18.jpg)

Angioedema
• Rapid swelling of the dermis, subcutaneous tissue
mucosa and submucosal tissues
• Skin is swollen, tender and warm
• May last days or resolve spontaneously
![Page 20: Region VIII EMS Systems July 2016 Version July 2016 Dyspnea .pdf · respiratory distress • Provides earliest, most accurate indication of respiratory distress • Changes in capnography](https://reader033.fdocuments.net/reader033/viewer/2022041618/5e3d042cb3d7a473077ef968/html5/thumbnails/20.jpg)
Angioedema• Substances known to trigger allergic angioedema
– Certain types of food particularly nuts, shellfish, milk, eggs
– Certain medication- penicillin, aspirin, NSAIDS
– Insect bites and stings
– Latex
• Cases without an identifiable cause are known as idiopathic
angioedema. May be a problem with the immune system
causing it to misfire. Triggers include:
– Anxiety - Hot or cold temps
– Stress - Exercise
– Minor infections
![Page 21: Region VIII EMS Systems July 2016 Version July 2016 Dyspnea .pdf · respiratory distress • Provides earliest, most accurate indication of respiratory distress • Changes in capnography](https://reader033.fdocuments.net/reader033/viewer/2022041618/5e3d042cb3d7a473077ef968/html5/thumbnails/21.jpg)
Angioedema
• Hereditary angioedema is caused by a genetic mutation in
the C1 esterase inhibitor
• The body does not produce enough of this C1 protein
• C1 plays an important role in regulating the immune
system
• Triggers include : Trauma- including surgery and
infection, oral contraceptives, and pregnancy
![Page 22: Region VIII EMS Systems July 2016 Version July 2016 Dyspnea .pdf · respiratory distress • Provides earliest, most accurate indication of respiratory distress • Changes in capnography](https://reader033.fdocuments.net/reader033/viewer/2022041618/5e3d042cb3d7a473077ef968/html5/thumbnails/22.jpg)
Angioedema
• Acute episodes often involve the lip, eyes, and face.
• May also affect other parts of the body including
respiratory and gastrointestinal mucosa.
• Laryngeal swelling can be life threatening
• Often associated with local burning sensation and pain
• Pronounced itchiness and local erythema
![Page 23: Region VIII EMS Systems July 2016 Version July 2016 Dyspnea .pdf · respiratory distress • Provides earliest, most accurate indication of respiratory distress • Changes in capnography](https://reader033.fdocuments.net/reader033/viewer/2022041618/5e3d042cb3d7a473077ef968/html5/thumbnails/23.jpg)
Angioedema
• Severe attacks can indicate the onset of systemic
anaphylaxis
• Characterized initially by dyspnea
• Medications used in treating urticaria and anaphylaxis are
also used in treating angioedema
• In severe cases of laryngeal edema a surgical airway may
be needed

Capnography
• Measures:– Ventilation: for patient with a pulse
– Perfusion: When patient is pulseless
– Partial pressure (mmHg) or volume (% vol) of CO2 in the
airway at the end of exhalation
– Breath-to-breath measurement provides information within
seconds
– Not affected by motion, artifact, poor perfusion or dysrhythmias

Capnography
• Reflects how effective our interventions are
• Can be utilized to more objectively determine a patient’s
respiratory distress
• Provides earliest, most accurate indication of respiratory
distress
• Changes in capnography waveform provide earliest
indication of apnea, upper airway obstruction and
laryngospasm or worsening of patient’s condition
![Page 36: Region VIII EMS Systems July 2016 Version July 2016 Dyspnea .pdf · respiratory distress • Provides earliest, most accurate indication of respiratory distress • Changes in capnography](https://reader033.fdocuments.net/reader033/viewer/2022041618/5e3d042cb3d7a473077ef968/html5/thumbnails/36.jpg)
Capnography
• Utilization in upper airway conditions
• Apnea:
– No waveform, no chest wall movement, no breath sounds
• Upper airway changes or obstruction:
– chest wall moving
– decrease or no breath sounds
– May be responsive to airway maneuvers with a return of
waveform or improvement in waveform

tachypnea and a normal waveform
• Deliver oxygen to maintain SPO2 above 94%

Lower Airway Condition
Pneumothorax A pneumothorax occurs when
the potential space between the
parietal and visceral pleura of
the lung fills with air and
collapses the lung. It can occur
spontaneously or following
trauma or pathology

Lower Airway Condition
Primary Spontaneous Pneumothorax
• Risk factors Spontaneous Pneumothorax
– Age 15-30 years old
– Male have higher incidence than women
– Tall thin stature

Lower Airway Condition
Secondary Pneumothorax• Secondary pneumothorax occurs in the presence of existing lung
pathology
• Pneumonia is a possible cause of pneumothorax. Consider
Pneumocystis jiroveci pneumonia (PCP) , toxoplasmosis, and
Kaposi sarcoma in patients with human immunodeficiency virus
infection (HIV). A patient with HIV can have spontaneous
pneumothorax as the presenting symptom of their illness. HIV
carries a lifetime risk of 6% for pneumothorax, and about 85% of
that number is related to PCP pneumonia.

Asthma• Obstructive lower airway
diseases are characterized
by diffuse obstruction to
airflow within the lungs.

Treatment COPD
• Emergency management
– Oxygen to maintain saturation of 92%*
• An oxygen saturation that falls into the 80’s and pale or cyanotic
extremities requires aggressive airway and ventilation management
• CPAP has been shown to decrease work of breathing, increase
oxygenation and decreasing the need for intubation
• NEVER WITHOLD OXYGEN FROM A HYPOXIC PATIENT

CPAP
• Improves respiratory function in asthma/COPD
• Improvement seen due to:
– Decrease work of breathing/ reduction in fatigue
– Improved oxygenation
– Splinting of larger airways and bronchioles to reduce airway
collapse and mucous plugging

patient with prescribed inhaler.
3. Reassess patient's respiratory status and begin transport
4. At discretion of Medical Control, additional doses of inhaler may be given
5. ALBUTEROL 2.5 mg (3 mL) via nebulizer per System-specific procedure
6. Consider possibility of congestive heart failure (CHF) / pulmonary edema in
wheezing patient, if patient has a history of CHF, and/or pulmonary edema. If so,
treat per PULMONARY EDEMA SOP, p. 22.
ALS 1. Adult Initial Medical Care SOP, p. 4-5 2. ALBUTEROL 2.5 mg (3 mL) via nebulizer 3. Partial response: repeat ALBUTEROL immediately 4. If no response to ALBUTEROL or patient in severe respiratory distress:
consider NIPPV / CPAP per System-specific procedure
If age ≤ 50 and patient has no history of cardiac disease, consider EPINEPHRINE 1:1000 0.3 mg IM
If age > 50 and/or cardiac disease history, contact Medical Control
5. If imminent respiratory arrest, INTUBATE and use in-line ALBUTEROL 2.5 mg (3 mL)

Hyperventilation syndrome
• Respiratory disorder, psychologically or physiologically
based, involving breathing to deeply or too rapidly
• Causes are unknown
• Sudden and everyday are two forms
• Causes carbon dioxide levels to decrease

Hyperventilation syndrome
• Lower levels of carbon dioxide reduce blood flow to the
brain resulting in nervous system and emotional
symptoms– Weakness
– Fainting
– Dizziness
– Confusion
– Agitation
– Feeling as if you can’t breathe

Hyperventilation
• Over breathing can also cause Calcium levels to drop in your blood which
results in these CNS symptoms
– Numbness and tingling (in arms and around mouth)
– Spasms or cramps in hands and feet
– Muscle twitching
• May also cause cardiac symptoms– Chest pain or tenderness
– Shortness of breath
– Wheezing
