Respiratory Disorders
Question | Answer |
---|---|
Influenza | Upper respiratory disease. Upper respiratory viral infection. |
Influenza viral strains | A - more serious forms during flu season B - more serious forms during flu season C - cause mild S/S. often confused with a cold. Always hanging around. |
S/S of Influenza | Prodromal Stage: feel like coming down with something Clinical Stage: congestion and sore throat, runny nose and fever. |
Diagnosis of Influenza | Self diagnosed based on S/S. Doctor to confirm |
Treatment for Influenza | - Palliative Treatments: Fluids, Rest, Decongestants, Hot soup |
Prognosis for Influenza | Get better in 1 week to 10 days Almost never fatal. Some people get a secondary bacteria infection. |
Lower Respiratory Disease | People with weak immune systems are at an increased risk. Could lead to Pneumonia. Could be fatal. |
Diagnostic procedures for Lower Respiratory Diseases. | -Auscultation: listening for Rales and abnormal breath sounds. Make sure air is flowing in and out. -Chest X Ray |
S/S for Lower Respiratory Disease | Hemoptysis, Hypoxia, Hypercapnea, Respiratory acidosis, Atelectasis, Pneumothorax |
Hemoptysis | Coughing up blood from lungs. |
Hypoxia | A lack of oxygen. |
Hypercapnea | An excess of carbon dioxide. |
Respiratory Acidosis | A decrease in the pH of body fluids due to a buildup of carbon dioxide. |
Atelectasis | A partial or complete collapse of lung tissue. |
Pneumothorax | The presence of air between the Visceral pleura and the Parietal pleura. |
Chronic Obstructive Pulmonary Disease (COPD) | Transitional stage between Bronchitis and Emphysema. Has the signs of both. Is controlable. |
Chronic Bronchitis | Has bronchitis for three months out of a year for 2 consecutive years. Affects Bronchi (large airways). Can be cured. Can lead to emphysema. |
Obstruction to air flow in chronic bronchistis. | Inflamation and mucus obstruct bronchi. Obstructive disease. |
Eitology of Chronic Bronchitis | Infection (not usual) or Irritation (most likely and ususally from smoking or occupational exposure). Smoking is the most common cause of Chronic Bronchitis. |
S/S of Chronic Bronchitis | Coughing with mucus. Easily SOB. Because the walls are inflamed they make more mucus. |
Diagnosis of Chronic Bronchitis | Based on S/S. Cough up mucus = bronchitis |
Treatment for Chronic Bronchitis | Remove source or couse of Irretation. Stop smoking or treat infection. |
Prognisis for Chronic Bronchitis | Reversible but eventually leads to damage to other parts of the lung like the alveoli. COPD stage in about 15 years. If it continues longer it leads to emphysema. |
Emphysema | Break down of elasticity of respiratory tissues. Not reversable. Poor gas exchange. Exhaling is no longer passive. |
Bullae | A group of overinflated alveoli. A lot of oxygen in the bullae is too far from the wall of the alveoli to be of use. |
Obstruction of air flow in Emphysema | Loss of elacticy |
Eitology of Emphysema | Chronic Bronchitis (most common). A small amount of people have a genetic defect in how their body processes elastin. |
S/S of Emphysema | Pink Puffers and Blue Bloaters. Both have labored breathing. |
Pink Puffers | -Oxygen levels = normal -CO2 levels = slightly elevated (Pink skin) -pH = normal -Barrell chest with thin arms and legs -Weight loss -increase mucus because air is not moving out |
Blue Bloaters | -Hypoxia (Blue skin) -Hypercapnea -Respiratory Acidosis -Cor Pulmonale:RCHF leads to systemic edema (bloat) |
Diagnosis for Emphysema | Pulmonary Function Test. |
Treatment for Emphysema | Stop smoking. Eventually the damage is done. Supplimental oxygen at Blue Bloater Stage. |
Prognosis for Emphysema | Pink eventually becomes Blue. Irreversable. When it reaches a certain point it is fatal. People die of respiratory or heart failure. |
Bronchial Asthma | Obstruction of smallest branches of airway. Spasm of muscle cell around small airways causing obstruction. No air to alveoli. |
Obstruction of air flow for Asthma | Bronchosmpasm. Inflammation leads to more mucus. |
Eitology of Asthma | Idiopathic, Familial, More common in people with allergies, More common in people who live in crowded areas. Can start at any age but usually starts at a young age. |
Triggers for Asthma | Intrinsic: Stress, emotions, exercise induced, anxiety induced. Extrinsic: Inhaled Alllergens (pollen), Inhaled Irritants (dust), Cold air. |
S/S of Asthma | Wheezing, severe difficulty breathing, coughing up thick mucus. |
Diagnosis of Asthma | Pulmonary Function Test: abnormal results even when not having an asthma attack. |
Treatment of Asthma | Bronchodilator Corticosteroids Inhaler to prevent attacks Injection when having an attack |
Bronchiodilators | relax muscle cells in smallest branches of lung. Chemically related to Adrenaline. |
Corticosteroids | Decrease swelling. Chemically related to Cortazone. |
Inhalers | Allow us to use a smaller dose of medication. Medication goes directly to lungs. |
Prognosis of Asthma | -Most are managable -Medications are very good at controlling attacks -Childhood asthma sometimes goes away in puberty -If still present after puberty it is a lifelong disease. -If you do not respond to treatment it can be fatal. |
