Presentation Transcript

  1. Respiratory Emergencies

  2. Respiratory Failure A condition that occurs when respiratory system is unable to adequately exchange Oxygen and Carbon Dioxide between environment and tissues of the body

  3. Respiratory Failure • PaO2 < 60 mmHg • PaCO2 > 50 mmHg

  4. Types of Respiratory Failure • Type I : Oxygenation Failure (Hypoxemic) • Type II : Ventilation Failure (Hypercapnic)

  5. Asthma Factors Determine Severe Asthma History: - Frequent Attacks - Excessive use of - Bronchodilators - Steroids - Previous admission to ICU

  6. Asthma Physical Examination • Inability to speak • Cyanosis • Respiratory rate >30/mt • Heart Rate >115/mt • Pulsus Paradoxus >10 mmHg • Silent chest

  7. Asthma • Blood Gases • Respiratory acidosis • Hypoxemia (Low PO2) • Hyper carbia (High PCO2)

  8. FVC 100 75 50 25 FEV1 > 75% NORMAL = FVC 0 1 2 3 4 5 6 7 8 TIME

  9. FVC 100 75 50 25 FEV1 Airway Obstruction = FEV1 < 75% FVC 0 1 2 3 4 5 6 7 8 TIME

  10. Asthma Treatment • Oxygen by Mask • Salbutamol (Ventolin) inhaler • Aminophylline I.V • Corticosteroids

  11. Pulmonary Edema Risk Factors: - Smoking - DM - HTN - ↑Lipids - Rheumatic Heart Disease Symptoms: - Shortness of Breath - PND - Orthopnea

  12. Pulmonary Edema Physical Examination: - Gallop Rhythm - ↑JVP - Basal Crakles - Lower Limb Edema Investigations:- CXR,ECG,ECHO Treatment :- Oxygen - Diuretics - Digoxin - After load Reduction.

  13. Pneumothorax • Traumatic • Spontaneous -Tall Thin

  14. Pneumonia History:- Cough - Shortness of Breath - Fever - Sputum Examination: - Dullness - ↑ Vocal fremitus - Bronchial Breathing - Crackles Treatment: - Oxygen - Antibiotics

  15. Pulmonary Embolism Predisposing factors: - Immobilization - Recent surgery - Hyper coagulable state

  16. Acute Respiratory Distress Syndrome Causes: - Aspiration Pneumonia - Near Drowning - Chest Trauma - Severe Pneumonia

  17. Atelectasis Causes: • Foreign body • Endobronchial lesion • Excessive secretions

  18. Respiratory Failure Type II : Ventilation Failure (Hypercapnic)

  19. Causes Of Respiratory Failure Outside The Lung

  20. Respiratory Failure COPD: Causes:- Emphysema - Chr. Bronchitis

  21. Shortness of Breath on Exertion

  22. Pursed Lip Breathing

  23. FVC 100 75 50 25 FEV1 > 75% NORMAL = FVC 0 1 2 3 4 5 6 7 8 TIME

  24. FVC 100 75 50 25 FEV1 Airway Obstruction = FEV1 < 75% FVC 0 1 2 3 4 5 6 7 8 TIME

  25. THE END
