Study Notes
Respiratory Disorders Overview
- Respiratory system divided into upper and lower anatomical areas.
- Upper respiratory tract conducts air, while lower includes trachea, bronchial tree, and lungs for gas exchange.
- Lungs are encased in pleura; pulmonary circulation and ventilation muscles important for respiratory function.
- Disorders arise from airway obstructions, alveolar damage, reduced lung expansion, or impaired blood flow.
Mechanism of Breathing
- Inspiration involves contraction of external intercostal muscles, elevating ribs.
- Expiration engages internal intercostal muscles, lowering ribs as external intercostals relax.
Lung Volumes and Capacities
- Tidal volume (TV): air entering and exiting with each breath.
- Inspiratory reserve volume (IRV) & expiratory reserve volume (ERV): maximum air moved beyond normal breathing.
- Vital capacity (VC): total air exchanged during maximum inspiration and expiration (approximately 4,800 ml).
- Residual volume (RV): air remaining in lungs post-exhalation (approximately 1,200 ml).
- Total lung capacity encompasses all volumes, typically around 6,000 ml.
Infectious Diseases
- Common upper respiratory infections to be familiarized.
- Different types of pneumonia categorized and compared.
- Primary tuberculosis has unique effects versus secondary tuberculosis.
Cystic Fibrosis and Bronchogenic Carcinoma
- Cystic fibrosis pathophysiology and complications outlined.
- Etiology and pathophysiology of bronchogenic carcinoma require understanding.
Asthma and Lung Diseases
- Types of asthma distinguished with focus on acute attack mechanisms and manifestations.
- Emphysema and chronic bronchitis compared for pathophysiological differences.
Pulmonary Disorders
- Causes of pulmonary edema and its impact on oxygen levels addressed.
- Effects of pulmonary emboli classified by size: small, moderate, and large.
- Atelectasis causes and its consequences on ventilation and oxygenation defined.
Pleural Effusion and Pneumothorax
- Impact of pleural effusion on ventilation clarified.
- Different types of pneumothorax explained, along with their effects.
Chest Injuries and Respiratory Distress
- Flail chest injury consequences on ventilation and circulation discussed.
- Infant respiratory distress syndrome signs and pathophysiology detailed.
- Adult respiratory distress syndrome causes and pathophysiology described.
Respiratory Failure
- Acute respiratory failure etiology and blood gas changes explained.
- Sleep apnea cause, effects, and complications outlined.
