Emphysema ppt
Emphysema is a lung disease that causes damage to the air sacs in the lungs called alveoli, resulting in shortness of breath. It is usually caused by smoking or long-term exposure to irritants or pollutants. As the disease progresses, the alveoli are destroyed, reducing the lungs' ability to take in oxygen. Symptoms start mild but worsen over time, ultimately causing severe shortness of breath and respiratory failure if left untreated. Treatment focuses on quitting smoking, medications, surgery, pulmonary rehabilitation, and managing symptoms.
Emphysema
Emphysema is a lung disease where the air sacs (alveoli) are progressively destroyed, resulting in fewer and larger air spaces. The main causes are smoking and genetic conditions. In emphysema, elastic fibers and alveolar walls are broken down due to an imbalance between proteases from inflammatory cells and their inhibitors like alpha-1 antitrypsin. Symptoms include shortness of breath, cough, and fatigue. Diagnosis involves pulmonary function tests, chest imaging, and blood tests. Treatment focuses on bronchodilators, supplemental oxygen, and reducing risk factors.
Bronchiectases
Bronchiectasis is a chronic lung condition defined by the permanent dilation of the bronchi. It has both congenital and acquired causes such as infections from tuberculosis, pneumonia, or cystic fibrosis. Symptoms include chronic cough, production of large amounts of purulent sputum, and recurrent lung infections. Diagnosis involves imaging like CT scans and pulmonary function tests. Treatment focuses on airway clearance techniques, antibiotics for infections, and surgery in severe cases. Nursing care aims to improve lung function and prevent infections through techniques like postural drainage and breathing exercises.

Empysema
Emphysema is a long-term lung disease that damages lung function and causes shortness of breath. It destroys necessary lung tissue and airways. Specifically, emphysema causes the creation of small holes in the alveoli, the air sacs responsible for oxygen exchange, resulting in not enough oxygen reaching the bloodstream. Smoking and air pollution are the primary causes of emphysema by damaging the lungs over many years. Symptoms include shortness of breath, coughing, wheezing, decreased tolerance for exercise, and pursed-lip breathing. Treatment focuses on bronchodilation, corticosteroids, oxygen therapy, and managing symptoms.

Respiratory Diseases -Obstructive lung diseases.ppt
The document discusses several lung diseases including obstructive lung diseases, restrictive pulmonary diseases, pulmonary infections, lung tumors, and diseases of the pleura. It provides details on specific conditions such as atelectasis, chronic obstructive pulmonary disease (COPD), emphysema, chronic bronchitis, asthma, and bronchiectasis. For each condition, it describes the pathogenesis, clinical presentation, morphology, and clinical course. It also compares and contrasts emphysema and chronic bronchitis.
Emphysema PPT
What is emphysema?
Emphysema is a condition that forms part of chronic obstructive pulmonary disease (COPD) and involves the enlargement of the air sacs in the lung.
The alveoli at the end of the bronchioles of the lung become enlarged because of the breakdown of their walls. The fewer and larger damaged sacs that result mean there is a reduced surface area for the exchange of oxygen into the blood and carbon dioxide out of it.
Definition
Emphysema is a condition in which the alveoli become stiff expands and continuously filled the air even after expiration. Emphysema is a chronic obstructive disease due to lack of elasticity in the lungs and alveoli surface area.
Classification
Panlobular (panacinar)
It is damage to the respiratory bronchi, alveolar ducts and alveoli. All air space in the little lobes much enlarged, with little inflammatory disease. The characteristics that have chest hyperinflation, and is characterized by dyspnea on exertion, and weight loss.
CENTRILOBULAR (CENTROACINAR)
The pathological changes mainly occur in the centre of the secondary lobes, and peripheral of acini remain good. Often there is chaos-ventilation perfusion ratio, which lead to hypoxia, hypercapnia (increased CO2 in the arterial blood), polycythaemia and heart failure episodes right. The condition leads to cyanosis, peripheral oedema, and respiratory failure.
CAUSES OF EMPHYSEMA
The biggest known cause or risk factor for emphysema - and for COPD - is smoking. Cigarette smoking is responsible for around 90% of cases of COPD. However, COPD will develop only in smokers who are genetically susceptible - smoking does not always lead to the disease.
Emphysema
Emphysema is a chronic obstructive pulmonary disease where the air sacs in the lungs (alveoli) become damaged, causing shortness of breath. It is primarily caused by cigarette smoking and long-term exposure to air pollution. The main symptoms are a productive cough, breathlessness, and wheezing. Signs include cyanosis, wheezing, fast breathing, hyperinflation of the lungs, and reduced breath sounds. Treatment focuses on stopping smoking, using bronchodilators and steroids, and supplemental oxygen. Prevention emphasizes avoiding pollution and respiratory infections by getting vaccinated.

Asthma
Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath. For some people, asthma is a minor nuisance
Pulmonology part 2 resp diseases
The document provides an overview of managing various respiratory disorders including maintaining the airway, supporting breathing, administering oxygen, and treating specific conditions like asthma, pneumonia, lung cancer, and pneumothorax. Assessment involves focused history and physical exam to identify underlying causes and guide treatment. Management focuses on oxygenation, ventilation support, establishing IV access, and administering medications as appropriate for each condition.
Emphysema and alfa 1 antitrypsin
- Emphysema can be caused by congenital factors, smoking, or alpha 1-antitrypsin deficiency. It results in destruction of lung tissue and inability to exhale fully.
- In emphysema, the air spaces in the lungs enlarge and the walls between them are destroyed. This reduces the surface area for gas exchange.
- Chest x-rays show enlarged, hyperinflated lungs in emphysema patients. Lobectomy is often used to treat congenital lobar emphysema in infants.
COPD
Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term used to describe progressive lung diseases including emphysema, chronic bronchitis, and refractory (non-reversible) asthma. This disease is characterized by increasing breathlessness

WARTS
Warts are benign skin growths caused by human papillomavirus (HPV) infection. There are several types of warts that vary in appearance and location on the body, including common warts, plantar warts, flat warts, genital warts, and periungual warts. Warts are typically diagnosed through visual examination and rarely require a biopsy for confirmation. Treatment options include topical creams or destructive methods like cryotherapy. While many warts resolve on their own, others can persist for years or recur despite treatment.
Viral Gastroenteritis
Stomach flu a.k.a viral gastroenteritis is the inflammation of the stomach and intestines. Lets about its causes, types, pathophysiology, signs, symptoms, diagnosis and management.
Serous Otitis Media (SOM)
Otitis media with effusion, also known as serous otitis media or glue ear, is a condition where the middle ear fills with fluid without signs of active infection. It often occurs after acute ear infections and may be caused by Eustachian tube dysfunction or risk factors like cleft palate or common colds. Diagnosis involves tympanometry to measure eardrum mobility and audiometry to identify conductive hearing loss, while treatment focuses on fluid resolution through watchful waiting, medication, or ear tube insertion for persistent cases.
Secondary Hyperparathyroidism
Secondary hyperparathyroidism is a frequently encountered problem in the management of patients with chronic kidney disease (CKD). This slideshow introduces this topic, breaking down its etiology, pathophysiology, clinical presentation, prognosis, management including investigation and treatment.
RHINOSINUSITIS
Rhinosinusitis is commonly referred to as sinusitis. Here, we walk you through its classification, predisposing factors, pathophysiology, signs, symptoms, diagnosis, treatment, complications, and prognosis.
Diabetes Mellitus
Diabetes Mellitus is a chronic disease that can result in terminal consequences which will be discussed in this presentation. Due to its commonality, it is vital for everyone to have sufficient information about it. This slideshow takes you through the different types and characteristics of DM. The signs, symptoms, risk factors as well as its pathophysiology are covered. A standardized protocol for diagnosis and treatment is highlighted too.
Chronic Kidney Disease
Chronic Kidney Disease, a.k.a Chronic Kidney Failure, is a vast but serious topic that requires thorough study. This presentation entails the essentials - its stages, pathogenesis, risk factors, etiology, symptoms, diagnosis, treatment and prognosis.
Acute Renal Failure
Acute kidney injury (AKI), formerly called acute renal failure (ARF), is defined as an abrupt decline in renal function over hours to weeks. It is commonly caused by decreased renal blood flow, direct kidney damage, or urine flow obstruction. AKI is diagnosed through increased levels of blood urea nitrogen and creatinine and confirmed by kidney imaging and biopsy if needed. Treatment focuses on reversing the underlying cause, managing complications like fluid overload, and providing renal replacement therapy like hemodialysis if severe. The prognosis depends on the cause, with community-acquired AKI having a better prognosis than hospital-acquired AKI which is often part of multi-organ failure.
Clinical Anxiety
Anxiety can be caused by both psychiatric and medical factors such as environmental stressors, medical conditions, and drug use or withdrawal. Signs and symptoms of anxiety range from mild unease to severe panic and can last from seconds to years. A diagnosis of anxiety involves ruling out other potential medical causes through examination and testing. Treatment options include antidepressants which take a few weeks to work, benzodiazepines in small doses for short term relief, and psychotherapy such as cognitive behavioral therapy.

Here is a summary of Pneumothorax:
Pneumothorax, also known as a collapsed lung, is a condition that occurs when air leaks into the space between the lung and chest wall. This air buildup puts pressure on the lung, preventing it from expanding fully when you breathe. A pneumothorax can cause a complete or partial collapse of the lung.

EMPHYSEMA
- 1. © BY DR. SARAH D’SOUZA BDS
- 2. INTRODUCTION WHAT IS EMPHYSEMA ? Emphysema is pathologically defined as an abnormal permanent enlargement of air spaces distal to the terminal bronchioles, accompanied by the destruction of alveolar walls and without obvious fibrosis. This process leads to reduced gas exchange, changes in airway dynamics that impair expiratory airflow, and progressive air trapping
- 3. ETIOLOGY ▸Tobacco smoke ▸Marijuana smoke ▸Air pollution ▸Manufacturing fumes ▸α1-antitrypsin deficiency (AATD)
- 4. • Bronchioles lose their stabilizing function and therefore causing a collapse in the airways resulting in gas to be trapped distally. • Erosion in the alveolar septa causing there to be an enlargement of the available air space in the alveoli. • Sometimes, there is a formation of bullae with their thin walls of diminished lung tissue. PATHOPHYSIOLOGY
- 5. PATHOPHYSIOLOGY Smoking activates the inflammatory process. Inflammatory cells are released from polymorphonuclear leukocytes and alveolar macrophages to move into the lungs. Inflammatory cells are known as proteolytic enzymes, which the lungs are usually protected against due to the action of antiproteases such as the alpha1- antitrypsin. However, the irritants from smoking will have an effect on the alpha1-antitrypsin, reducing its activity.
- 6. PATHOPHYSIOLOGY Production and activity of antiprotease are not sufficient to counter the harmful effects of excess protease production. Destruction of the alveolar walls and the breakdown of elastic tissue and collagen. Reduction in the surface area for gas exchange, which increases the rate of blood flow through the pulmonary capillary system.
- 7. TYPES OF EMPHYSEMA ▸Centriacinar (centrilobular) emphysema ▸ Panacinar (panlobar) emphysema ▸Distal acinar (paraseptal) emphysema ▸Irregular emphysema
- 8. TYPES OF EMPHYSEMA Centriacinar (centrilobar) emphysema Most common; >20% Central or proximal parts of the acini, formed by respiratory bronchioles, are affected, while distal alveoli are spared Severe type affects the distal alveoli as well Seen in cigarette smokers
- 9. TYPES OF EMPHYSEMA Panacinar (panlobar) emphysema Lower lung zone Acini are uniformly enlarged, from the level of the respiratory bronchiole to the terminal blind alveoli Usually seen in α1-antitrypsin deficiency
- 10. TYPES OF EMPHYSEMA Distal acinar (paraseptal) emphysema The proximal portion of the acinus is normal but the distal part is primarily involved Unknown cause -> spontaneous pneumothorax in young adults Characteristic finding: multiple, contiguous, enlarged air spaces ranging in diameter from <0.5 mm to >2.0 cm Sometimes forming cystic structures that, with progressive enlargement, are referred to as bullae
- 11. TYPES OF EMPHYSEMA Irregular emphysema Acinus is irregularly involved Almost invariably associated with scarring Clinically asymptomatic
- 12. CLINICAL MANIFESTATIONS Difficult/laboured breathing Reduced exercise capacity Chest pain Bluish fingers/lips
- 13. DIAGNOSTIC PROCEDURES HISTORY AND PHYSICAL ‣ Risk factors - smoking, secondhand smoke, and home and occupational exposures to chemicals ‣ Family history - alpha-1-antitrypsin deficiency ‣ Examination - Abnormal breath sounds A barrel chest (Rounding of the chest) • Muscle wasting • Weight loss • Clubbing of nails • The use of accessory muscles
- 14. DIAGNOSTIC PROCEDURES CHEST X-RAY ‣ On an x-ray, emphysematous lungs look hyperlucent with normal markings from blood vessels being less prominent. ‣ The diaphragms also appear flattened due to the hyperinflation of the lungs (which pushes down on the diaphragm.) ‣ Unfortunately, changes on x-ray are not usually seen until the disease is quite extensive.
- 15. DIAGNOSTIC PROCEDURES OTHER INVESTIGATIONS ‣ PULMONARY FUNCTION TESTS ‣ SPIROMETRY ‣ LUNG PLETHYSMOGRAPHY ‣ ARTERIAL BLOOD GASES ‣ COMPLETE BLOOD COUNT
- 16. COMPLICATIONS Complication of emphysema ‣ Pulmonary failure with respiratory acidosis ‣ Hypoxia ‣ Coma ‣ Right-sided heart failure (cor pulmonale)
- 17. TREATMENT Complication of emphysema No treatment can reverse or stop emphysema. But treatment can help to: •Relieve symptoms •Treat complications •Minimize disability People with AAT deficiency may be candidates for replacement therapy.
- 18. TREATMENT Complication of emphysema A. Bronchodilators Inhalers. ◦ Tiotropium (Spiriva) ◦ Ipratropium (Atrovent) ◦ Albuterol (Proventil, Ventolin, others B. Corticosteroids C. Combination Corticosteroid/ Long-Acting Bronchodilator Inhalers. ◦ Budesonide and formoterol (Symbicort) ◦ Fluticasone and salmeterol (Advair) ◦ Mometasone and formoterol (Dulera)
- 19. TREATMENT Complication of emphysema ‣ Antibiotics ‣ Oxygen therapy ‣ Pulmonary rehabilitation ‣ Lung volume reduction surgery ‣ Lung transplant
