Study Notes
Lungs Anatomy
- Upper airway consists of the nose, nasal cavity, pharynx, and larynx.
- Lower airway includes the trachea, bronchi, bronchioles, and alveoli.
- Right side of the heart pumps deoxygenated blood to the lungs for oxygenation.
Oxygenation
- Essential for survival, involves the exchange of oxygen and carbon dioxide in the lungs.
Obstructive Pulmonary Disorders
- Characterized by increased resistance to airflow.
- Notable conditions include:
- Asthma: Inflammation and narrowing of airways.
- COPD (Chronic Obstructive Pulmonary Disease): Long-term respiratory conditions that obstruct airflow.
- Bronchiectasis: Abnormal widening of the bronchi.
- Sleep-disordered breathing: Interruption of normal breathing during sleep.
Restrictive Pulmonary Disorders
- Marked by reduced lung expansion and decreased total lung capacity.
- Key conditions include:
- Pulmonary fibrosis: Scarring of lung tissue, leading to stiffness.
- Pneumoconiosis: Lung disease caused by inhalation of harmful dust.
- Thoracic cage deformities: Physical abnormalities that restrict lung expansion.
Pulmonary Function
- Smoking is the primary risk factor for various lung diseases, including effects from secondhand smoke.
- Occupational and environmental exposures can increase risks for lung diseases.
- Bronchodilation occurs when bronchioles dilate, enhancing airflow, mediated by the sympathetic nervous system (SNS) via Beta-2 adrenergic receptors.
- Bronchoconstriction reduces airflow due to constriction of smooth muscle in bronchioles from the parasympathetic nervous system (PNS).
- Leukotrienes and histamine released by white blood cells contribute to bronchoconstriction.
Lung Compliance
- Refers to the flexibility of the lungs and their ability to expand.
Pleural Membrane
- Lines the chest cavity and encases the lungs, facilitating optimal breathing mechanics.
Hypoxia and Hypercapnia
- Hypoxia: Lack of oxygen in the bloodstream.
- Hypercapnia: Elevated levels of carbon dioxide in the blood; may occur alongside hypoxia.
- Both conditions indicate impaired gas exchange in the lungs.
Chronic Conditions
- Chronic hypercapnia: Defined by PaCO2 levels greater than 45 mm Hg; symptoms include headache and drowsiness.
- Chronic hypoxia: Maintained PaO2 levels ideally between 90 to 100 mm Hg.
