Chronic lung disease wherein the airways narrow due to inflammation/blocked by mucus
Asthma
Obstructs airflow
The obstruction is reversible; asthma symptoms subside & lung function may be normal/near normal between attacks
Causes of difficulty breathing in asthma
Inflammation
Mucus in airways
Muscle tightening in airway
Asthma symptoms
Coughing
Wheezing
Shortness of breath
Chest tightness
Sneezing and runny nose
Itchy, inflamed eyes
Asthma medications
Long-term drugs
Rescue or quick relief drugs
Asthma diagnosis
Spirometry - breathing test, measure how much & fast you exhale air
COPD
Inflammatory disorder that's not fully reversible, typically progressive, airflow obstruction
Diseases that make up COPD
Emphysema
Chronic Bronchitis
COPD symptoms
Cough
Wheezing
Shortness of breath
Dyspnea
Emphysema
Alveoli become damaged and less elastic; air sacs become damaged and die off, results in smaller surface area for lungs to take oxygen into the blood and remove co2 from body. This can lead to hypoxia (lack of oxygen in the blood) and buildup of toxic waste products. Damage is permanent
Risk factor for emphysema
Cigarette smoking - leading cause of emphysema. Destroys lung tissue and causes inflammation of airways
Chronic Bronchitis
Inflammation of the lining of the bronchial tubes; classified as chronic when symptoms (primarily productive cough) lasts more than 3 months within a span of 2 years
Lung Cancer
Abnormal cells grow in an uncontrolled way in the lungs; leading cause of cancer-related deaths worldwide
Types of lung cancer
Small cell carcinoma (previously known as oat cell carcinoma; rare and fast-growing)
Genetic (inherited) disease that causes sticky, thick mucus to build up in organs, including lungs and pancreas; thick mucus clogs airways, blocks ducts in pancreas causing problems in digesting
Forms of Cystic Fibrosis
Atypical CF (milder & may only affect 1 organ; comes later in life)
Typical / classic CF (shows in first few years of a child's life and caused by mutations in a gene called the cystic fibrosis transmembrane conductance regulator (CFTR))
Pneumonia
Infection that inflames the alveoli in one / both lungs. Air sacs may fill with fluid or pus (purulent material). This is caused by bacteria, viruses or fungi.
Types of pneumonia
Bacterial Pneumonia (most common cause, occur on its own. Most common bacteria is streptococcus pneumoniae)
Viral Pneumonia (often mild & goes away on its own)
Fungal Pneumonia (most common in people who have chronic health problems)
Pleural effusion
Accumulation of fluid in between the parietal & visceral pleura, called pleural cavity, resulting from excess fluid production or decreased lymphatic absorption; "water on the lung"
Causes of pleural effusion
Congestive heart failure
Pneumonia
Malignancy
Pulmonaryembolism
Types of pleural effusion
Transudative Pleural Effusion (fluid leaking into the pleural space)
Exudative pleural effusion (blood or lymph vessels are blocked)
