Airway emergencies

  1. dyspnea 
    short of breath or difficulty breathing 
  2. upper airway 
    nose mouth jaw oral cavity pharynx and larynx 
  3. respiration
    • exchange of oxygen and carbon dioxide
    • 02 is provided to the blood and co2 is taken out takes place rapidly at the alceoli 
    • if co2 rises above normal the person breathes more rapidly and more deeply 
  4. pathophysiology 
    • refers to  condition under which body processes are not working as they should and as a result, interfere with normal respiration. 
    • abnormal or pathologic conditions in the anatomy of the airway, disease processes, and tramatic conditions can prevent the proper exchange of oxygen and co2
    • in addition the pulmonary blood vessels themselves may have abnormailies that interfere with blood flow and thus with the transfer of gases 
  5. carbon dioxide retention 
    a condition characterized by a chronically high blood level of carbon dioxide win which the respiratory center no longer responds to high blood levels of carbon dioxide 
  6. hypoxic drive 
    • back up system to control respirations when oxygen levels fall 
    • the low blood oxygen level causes the resp center to respond and stimulate resp. 
    • people with chronic lung diseases frequently have a chronicall high level of carbon dioxide in teh bool. giving too much oxygen to them may actually stop resp. 
  7. hypoxia 
    condition in which the body cells and tissues are deprived of oxygen 
  8. patients often have breathing difficulty and or hypoxia with :
    • upper or lowere airway infection 
    • acute pulmonary edema 
    • copd 
    • asthma 
    • hay fever 
    • anaphylaxis 
    • spontaneous pneumothroax 
    • pleural effusion 
    • pronlonged seizures 
    • obstruction of the airway 
    • pulmonary embolism 
    • hyperventilation syndrome 
    • environmental exposure 
    • carbon monoxide posioning 
    • infectious diseases 
  9. one or more of teh following situations most likely exist
    • gas exchange between teh alveoli and pulmonary circulation is obstructed by fluid in the lung, infection or collapsed alveoli(atelectasis)
    • the alveoli are damaged and cannot transport gases properly across their own walls 
    • the air passages are obstucted by muscle spasm, mucus or weakend floppy airway walls 
    • blood lfow to the lungs is obstucted by blood clots 
    • the pleural space is filled with air or excess fluid so the lungs cannot properly expand 
  10. pulmonary edema
    • a buildup of fluid in the lungs, uaually as a result of congestive heart failure
    • the left side of the heart cannot remove blood from the lungs as fast as the right side delivers . as a result fluid biulds up withing the alvioli and in the lung tissure 
    • patient expirenences dyspnea with rapid, shallow respirations ...frothy pink sputum at the nose and mouth 
    • causes: poisioning inhaling large amounts of smoke, tramatic injuries  exposure to high altitudes 
  11. chronic bronchitis
    • irritation of the major lung passageways from infectious diseae or irritants such as smoke
    • excess mucus is constantly porduced, obstucting small airways and alveoli. 
    • protective celss and lung mechanism that remove foreign particles are destoryed, further weaking the airways. 
    • pneumonia develops easily when the air passages are persistently obstructed
  12. COPD chronic obstructive pulmonary disease
    • slow porcess of dilation and disruption of the airways and alveoli caused by chronic bronchial obsturction 
    • 4th leading cause of death 
    • result of direct lung and airway damages from repeated infections most often results from cigarette smoking
  13. emphysema 
    • is a loss of teh elastic material around the air spaces as a result of chronic streching of the alveoli when inflamed airways obstruct easy expulsion of gases. 
    • air is no longer expelled rapidly 
    • disease of the lungs in which there is extreme dilation and eventual destruction of the pulmonary alveoli with poor exchange of oxygen and carbon dioxide 
  14. COPD vs CHF 

    • disease of the lung characterized by shortness of breath and wheezing 
    • home oxygen, broncholdilators, and steriods used for treatmetn 
    • breathing progressively worse over time 
    • usually in long term smokers 
    • shortness of breath mostly on exertion 
    • chronic coughing 
    • sputum may be thick 
    • no jugular vein distenion or dependent edema 
    • patient usually then with a barrel chest 
  15. COPD VS CHF 
    • a disease of the heart characterized by shorness of breath edema and weakness 
    • diuretics prescribed to help promote cardiac function and to reduce fluid loads on the heart 
    • sudden onset of shortness of breath 
    • patient may or may not smoke 
    • shortness of  breath all of the time 
    • coughing 
    • sputum may be pink and frothy 
    • jugular vein distention and dependent edema 
    • may have distended abs 
  16. asthma
    • an acute spasm of the smaller air passages called bronchioles, associated with exessive mucus production and with sweeling of the mucous lining of the respiratory passages
    • wheezing--indicates of partial lower airway obsturction 
    • may be caused by an allergic response to specific foods or some other allergen substance that causes allergic response 
  17. hay fever 
    • allergic response usually to outdoor airborne allergens such as pollen or somethimes indoor allergens such as dust mites also called allergic rhinitis 
    • causes cold like symptoms
  18. anaphylactic reactions
    • an extreme life threatening systemic allergic reaction that may include shock and respiratory failure 
    • airway swelling and dilation of blood vessesl all over teh body, which may lower bp 
    • widespread itching and signs and syptoms similar to astma 
    • airway may swell so much that breathing problems can progress form extreme difficulty in breathing to total airway obstruction in a few minutes 

    • epinephrine is the treatment of choice
    • oxygen and antihistamines are usuful 
  19. pneumothroax 
    a partial or complete accumulation of air in the pleural space 

    • caused by tramua 
    • lung ruptures by a hard cough 
    • becomes dyspneic and might complain of pleurtic chest pain sharp stabbing pain on one side that is worse during inspiration and expiration or with certain movement of teh chest wall, 
    • listening to chest--detect absent or decreased breath sounds on the affected sides 
  20. plural effusion 
    • collection of fluid outside the lung on the one or both sides of teh chest 
    • compresses the lun or lungs and causes dyspnea this fluid may collect in large volumes in response to to any irritaiotn infection CHF or cancer 
    • you will hear decreaed breath sounds over teh region of the chest where fluid has moved the lung away from the chest wall 
  21. prolonged seizures 
    • a seizure is caused by a disruption in the electrical activity in teh brain 
    • typical the seizure lastsonly minutes and the patient reagain consciousness 
    • epilipticus- seizures longer than 20 min 
    • sizure taht lasts one to three min the patients will have some impairment in his or her ability to breath 
    • prolonged seizure-unconscious patient has no control over teh airway constant muscle contractions will interfere with ability of teh chest to expand and the patient will hypoventialate and become hypoxic could be apneic 
    • hyperthermia dehydration and hypoglyciema 
  22. obstuction of the airway 
    • semiconscious and unconscious ind the obstuction may be the result of aspiration of vomitus or a foreign object 
    • always consider upper airway obstuction from a foreign body first in patiens who were just eating 
  23. Pulmonary embolism 
    embouls--a blood clot or other substance in teh circulatory system that travels to a blood vessel where it causes a blockage 

    • a blood clot that breaks off from a large vein and travels to the blood vessesl of the lung, causing obstruction of blood flow 
    • symptoms and signs include: dyspnea, acute chest pain, hemoptysis(coughing up blood), cyanosis, tachypnea , and carying degress of hypoxia 
  24. hyperventilation 
    • rapid or deep breathing that lowers teh blood carbon dioxide level below normal (bodies attempt to stay alive)--indicatior of a life threating illness 
    • body is trying to compensate for acidosis--build up of excess acid in the blood or body tissues that results from the illness 
    • blood acidity can be diminshed by excessive breathing because it blows off too much co2 the result is a relative lack of acids. alkalosis-- the build up of excess base (lack of acid) in the body fluids
  25. hyperventilation syndrome 
    alkalosis causes it
    • occurs in the absense of other physical problesms. the presirations of a person who is expericning hyperventilation sydnrome maybe be as high as 40 sahallow breaths or low as only 20 very deep ventalations
    • anxiety dizziness, numbness tingling of hands and feet
