Study Notes
Pulmonary Hypertension
- High blood pressure in the arteries of the lungs, causing the heart to work harder to pump blood through the lungs
Causes and Risk Factors of Pulmonary Diseases
- Smoking: leading cause of many pulmonary diseases, including COPD and lung cancer
- Environmental Factors:
- Exposure to air pollution
- Occupational hazards (asbestos, silica, coal dust)
- Indoor pollutants (mold, secondhand smoke)
- Genetic Factors: genetic predisposition to certain pulmonary conditions, such as alpha-1 antitrypsin deficiency
- Infections: bacterial, viral, and fungal infections can cause pneumonia and exacerbate other pulmonary diseases
- Lifestyle Factors:
- Poor diet
- Sedentary lifestyle
- Obesity
Symptoms of Pulmonary Diseases
- Shortness of breath
- Persistent cough
- Wheezing
- Chest pain or tightness
- Fatigue
- Bluish tint to lips or fingernails (cyanosis)
- Coughing up blood (hemoptysis)
- Fever and chills (in the case of infections)
Treatments for Pulmonary Diseases
- Medications:
- Inhalers
- Steroids
- Antibiotics
- Chemotherapy drugs
- Oxygen Therapy: supplemental oxygen to improve breathing
- Pulmonary Rehabilitation: exercise programs and education to improve lung function and quality of life
- Surgery: lung resection or lung transplantation in cases of lung cancer or severe COPD
- Lifestyle Modifications:
- Smoking cessation
- Healthy diet
- Regular exercise
- Avoiding environmental triggers
The Respiratory System
- Air enters the body through the nose or mouth, passes through the pharynx, and then into the trachea
- Airways:
- Nose: primary entry point for outside air, equipped with hairs for air filtration
- Mouth: secondary entry for air, useful during nasal blockages or intense physical activity
- Throat: collects air from the nose and mouth, guiding it to the windpipe
- Sinuses: hollow spaces in the head bones that regulate air temperature and humidity
- Windpipe (trachea): passage from the throat to the lungs, dividing into bronchial tubes
- Gas Exchange:
- Oxygen moves from the lungs into the bloodstream
- Carbon dioxide moves from the blood into the lungs
- Occurs between the alveoli and a network of tiny blood vessels called capillaries
Prevention of Pulmonary Diseases
- Avoiding tobacco smoke and environmental pollutants
- Practicing good hand hygiene to prevent respiratory infections
- Getting vaccinated against influenza and pneumonia
- Maintaining a healthy lifestyle, including regular exercise and a balanced diet
- Seeking prompt medical attention for respiratory symptoms to prevent complications
