  3. 3. COPD• Bronchi and Alveoli Afffected• Chronic inflammation - chronic bronchitis and emphysema• Bronchioles – destruction of elastin/decilliation/increased numbers of goblet cells - lining becomes irritated and inflamed producing excess mucus that blocks the airways.• Alveoli – destruction of alveolar septum, reduced transfer of O2 and CO2, bullae, floppy airways prone to collapse• Slow progressive disease• THE EFFECTS OF COPD MEAN THAT LESS OXYGEN PASSES INTO YOUR BLOOD . less gas exchange area and reduced surface area for gas exchange/reduced compliance of lungs? Alveolar interdependence affected too
  4. 4. COPD• Mechanical effects• HYPERINFLATION – Passive - Diaphragm is flat (due to increased size of lungs pushing down on it) – Dynamic- they develop hyperinflation during the dynamic aspect of physical activity and, therefore, the problem gets worse or develops with tasks. – Costophrenic angle reduced – So need use of accessory muscles – bent over/hunch over to try and dome the diaphragm• Other Effects:• CorPulmonale (Enlargement of R ventricle in response to increased resistance/High BP• Stress incontinence• Constipation• Anxiety/Depression• CAUSES• Smoking is the major cause of COPD.• Other factors can be occupation, gender (males more likely), climate and childhood respiratory conditions.• Repeated infections
  5. 5. COPD – S&S• -Using accessory muscles• -Purse lip breathing (stops collapse of floppy airways)• -Barrel chest• -Ribs in at the bottom when breathing in (paradoxical breathing)• -Chronic dirty phlegm• -Wheezing or a whistling sound when breathing• -Feeling tired / Losing weight without trying• Hypercapnia (Hich PaCo2 in advanced disease) use hypoxic drive to trigger breathing
  6. 6. COPD- Complications/TreatmentTREATMENT• Quit smoking – advice on smoking cessation• Adopt a healthy lifestyle to prevent infectionsMedications-• Bronchodilators (inhaler) treat SOB• corticosteroid pills prevent and treat COPD flare ups• antibitotics treat infections that cause flare ups• flu and pneumonia vaccines• supplemental oxygen
  7. 7. COPD- Physio• PHYSIOTHERAPY• -Pulmonary rehabilitation therapy• Postural/gravity assisted position• -Exercise is very important to help stay fitter for longer and improve breathlessness• -Diaphragmatic breathing• -Active cycle of breathing• -Controlled coughing to get rid of mucus and prevent infections• -Percussion techniques• Long term O2• EXACERBATION – clear secretions and reduce WOB. Non – invasive ventilation• BIPAP• Bear in mind what their NORMAL o2 sat is (some use low O2 sats to trigger breathing)• MRC Dysponea scale
  8. 8. Primary CiliaryDyskinesia (PCD)• Primary Sructures affected: Cilia• Pathological process: uncoordinated ciliary beat leads to excess secretions. Inability to remove mucous• Clinical S&S:Recurrent infections of ears/sinuses and lungs. In children- perpetual runny nose/glue ear/chest infections• Potential Problems: Increased mucous• Radiology: N/A• Auscultation: Crackles due to excess mucous?• Predisposing Factors/Causes: Inherited condition • Management: Not a progressive disorder. Antibiotics and physio needed to delay onset of bronchiectasis. • Chest Physical Therapy to aid mucous removal • Cough Assist?????
  9. 9. Bronchiectasis• Primary Sructures affected: chronic irreversible distortion/dilation of bronchi• Pathological process: Chronic inflammation damages elastic/muscular components of airways. Warm environment of lungs + excess mucus-infection-inflammation obstruction viscous circle. Cilia are damaged. Progressive destruction occurs. Advanced disease= pulmonary heart disease• Clinical S&S: Large quantities sputum. Mucosal ulceration can cause haemoptysis. Finger clubbing. Dyspnoea (SOB)• Potential Problems: Fatigue. Loss appetite.• Radiology: ??• Auscultation: Secretions and collapsing airways on expiration cause coarse wheezes and crackles• Predisposing Factors/Causes: severe respiratory infection/foreign body inhalation/ • Management: Antibiotics for infections. Inhaled CF/TB/smoke inhalation/primary steroids for inflammation and reduction of ciliarydyskinesia sputum. • Reduces mucus clearance by 15% - patients need education in sputum clearance. • Postural drainage in severe cases • Hydration.ACB.Exercise Programme – lifelong programme required!
  10. 10. Pulmonary Tuberculosis (TB)• Primary Sructures affected: Lungs• Pathological process: bacterial infection from TB bacillus.• Clinical S&S: Fever/Night Sweats/Cough/Chest wall pain/Weight Loss/Haemoptysis and SOB, fatigue• Potential Problems: Tissue destruction and necrosis are balanced by healing and fibrosis.Affected tissue is replaced by scarring and cavities filled with cheese-like white necrotic material. During active disease, some of these cavities are joined to the air passages bronchi and this material can be coughed up. It contains living bacteria and can therefore pass on infection. Treatment with appropriate antibiotics kills bacteria and allows healing to take place. Upon cure, affected areas are eventually replaced by scar tissue.• Radiology:• Auscultation:• Predisposing Factors/Causes: 1/3 of • Management: Antibiotics for up to 6 months – population is infected with TB, which can very resilient become active if the hosts defence mechanisms are compromised due to poor • Devise exercise regimes within isolations rooms living/drug dependency/HIV. Diabetes.Low • Air – filtered mask to be worn at all times!! Weight
  11. 11. Asthma• Asthma is a long-term condition• Bronchioles are affected in asthma• Chronic inflammatory with airway narrowing and mucus plugging• Pathological process:• an asthma trigger stimulates excess immunoglobulin E (IgE) in serum. This fixes to Mast cells which then react to antigens and release bronchorestrictor substances- histamine• the muscles around bronchioles tighten airways become narrower and the lining of the airways becomes inflamed and starts to swell.• air flow can further be decreased by inflammation or excess mucus secretion• PERSISTENT INFLAMMATION leads to fibrosis of airway walls and irreversibility• Common triggers include house dust mitesanimal fur, pollen, tobacco smoke, exercise, cold air and chest infections.
  12. 12. Asthma – S& S• Clinical S&S: :• SOB• Tightening of the chest• Wheezing which can make a whistling sound when you breathe.• Coughing• Features of acute asthma:• PaO2 ↓ RR >25 PaCO2 ↓ Pulse>110 BP↑• DIAGNOSIS• The spirometer takes two measurements: the volume of air you can breathe out in one second (called the forced expiratory volume in one second or FEV1) and the total amount of air you breathe out (called the forced vital capacity or FVC). This can be done by the GP.• Predisposing Factors/Causes: A family history, Prolonged exposure to tabacco smoke as a child, Food allergy, Bronchiolitis as a child, Prem baby, Anxiety
  13. 13. Asthma - ManagementManagement: . Asthma can be well controlled in most people most of the time.• Inhalers• Inhaling a drug is an effective way of taking an asthma medicine as it goes straight to the lungs, with very little ending up elsewhere in the body. The drug used is Salbutomol – widens airways• Steroids are also used but these can have side effects in the long term.• PHYSIOTHERAPY MANAGEMENT• Breathing techniques can be used to help the patient to relax and feel in control - simple gentle abdominal breathing is used.• Exercise can help if aerobic training is used.
  14. 14. Asthma
  15. 15. Cystic Fibrosis
  16. 16. Cystic Fibrosis• Primary Structures affected:• It is a chronic progressive obstructive disorder affecting the exocrine glands. It is an inherited disease. Cystic Fibrosis affects the internal organs, especially the lungs and digestive system, by clogging them with thick sticky mucus. This makes it hard to breathe and digest food.• Pathological process: CF is caused by a mutation in the gene for required to regulate the components of sweat, digestive juices, and mucus.
  17. 17. Cystic Fibrosis- S&S• Clinical S&S: Symptoms of CF can include a troublesome cough, repeated chest infections, prolonged diarrhoea and poor weight gain. These symptoms are not unique to Cystic Fibrosis – difficult diagnosis• CF affects the pancreas, which makes it difficult for people with CF to digest food. This can cause malnutrition, which can lead to poor growth, physical weakness and delayed puberty.
  18. 18. Cystic Fibrosis- Physio• Predisposing Factors/Causes: Genetic• Management:• Chest physiotherapy is important because helps to prevent the thick, sticky lung secretions from blocking the air tubes. This helps to reduce infection and prevent lung damage.• ACTIVE CYCLE OF BREATHING• POSITIVE EXPIRATORY PRESSURE• OSCILLATING POSITIVE EXPIRATORY PRESSURE e.g. acapella, flutter.• Teach family how to do percussions etc• The patient needs to do exercise to keep the lungs from deteriorating and to improve physical strength and bullk.• Stretching exercises and being taught correct posture can help.
  19. 19. Acute Renal Failure• Primary Sructures affected: rapid loss of kidney function
  20. 20. Acute Renal Failure
  21. 21. Acute Renal Failure• S&S: Puffy ankles as kidneys not removing proteins so BCOP goes up – more fluid pushed into interstitial fluid space?? Also fluid retention causes oedema• Potential Problems: metabolic acidosis ( Kidneys retaining acid), high potassium levels, uremia, changes in body fluid balance, and effects to other organ systems.• Management: hinges on identification and treatment of the underlying cause. In addition to treatment of the underlying disorder, management of AKI routinely includes the avoidance of substances that are toxic to the kidneys, called nephrotoxins. These include NSAIDs such as ibuprofen, iodinated contrasts such as those used for CT scans, and others.Monitoring of renal function, by serial serum creatinine measurements and monitoring of urine output, is routinely performed. In the hospital, insertion of a urinary catheter helps monitor urine output and relieves possible bladder outlet obstruction, such as with an enlarged prostate.
  22. 22. Diabetes• Primary Sructures affected:• Pathological process:• Clinical S&S• Potential Problems• Radiology• Auscultation• Predisposing Factors/Causes• Management
  23. 23. Pulmonary Fibrosis/ idiopathic pulmonary fibrosisPrimary structures effected: In severe cases, symptoms can beLung tissue significantly worse and may includePathological progress: congestive heart failure, respiratory failure, and strokesis caused by repeated injury to small areas of lung. Results in inflammation of lungs causing scarring and stiffness.Clinical signs and symptoms:Thickened lung tissues cause decreased oxygen uptake from blood, brain and other organs don’t get enough oxygen.SOB, clubbing of nails, shallow breathing . Aching muscles and joints, decreased exercise tolerancePotential problems :decreased o2 to the brain, chronic dry cough.
  24. 24. Radiograpy: Management:• 10% of patients with IPF have normal • Allergen avoidance. chest x-rays. X-ray usually reveals • At present for IPF, there is no treatment shadows, mostly in the lower part of available which has been shown to the lungs. In addition, lung size tends improve the condition. to appear smaller than normal. • Counselling may be required in view of theAuscultation: may present with poor prognosis. crackles heard late in inspiration. • Supportive therapy may be helpful in the form of oxygen therapy and physiotherapyPredisposing factors/Causes: if bronchiectasisis present.No common cause known, can be a • Patients should be encouraged to take regular exercise to maintain their exercise side effect of tolerance. medication, expositor to • Patients should be encouraged to be pollution, smoking, viral vaccinated against influenza and infections. • Lung transplant is the only option which improves long-term survival.3 • (
  25. 25. • The pulmonary fibrosis organisation suggests:• Pulmonary rehabilitation :exercise training; breathing exercises and retraining; anxiety, stress and depression management; and nutritional counseling, to name a few.
  26. 26. PneumoniaPrimary Sructures affected:lung tissuePathological process:• infection of one or both lungs which is usually caused by bacteria, viruses, or fungi. contracted by breathing in small droplets that contain the organisms that can cause pneumonia. Normally immune system would suppress virus. if a person is in a weakened condition from another illness, a severe pneumonia can develop.• Alveoli fill with fluidClinical S&S:• symptoms of cold, high fever, shaking, discolored sputum production, sharp chest pain, skin color may change due to deoxygenatingPotential Problems:• ifthe spongy tissue of the lungs that contain the air sacs is more involved., oxygenation can be impaired, along with stiffening of the lung, which results in SOB. if low immune response pneumonia may be life threatening.
  27. 27. A)Normal chest, B) pneumonia• Radiology:• Auscultation: finecrackles, sometimes pleural rub.• Predisposing Factors/Causes: very young, very old, if immune system is weakened by any predisposing factors like long term illness• Management: oral or intervenous fluids
  28. 28. • Antiviral/antibacterial drugs• Oxygen if indicated• In acute stage physio is limited to positioning to much Va/Q and CPAP if hypoxemia persists despite 40% oxygen.• Modified postural drainage - this allows gravity to drain secretions from specific segments of the lungs• IPPB Machine• Shaking and vibes - to mobilize secretions• Coughing and huffing exercises - to expectorate secretions• Administer humidification - to mobilize secretions• Breathing exercises - Localized and Diaphragmatic• IPPB administration - to increase lung volumes• Mobilization of the patient - done to increase air entry, increase chest expansion, and to loosen secretions
  29. 29. PneumothoraxPrimary Sructures affected: pleural cavity between lung and chest wallPathological process: may occur spontaneously (primary) or in people with lung conditions (secondary). If either pleural layer is ruptured gas rushes into the pleural space either from inside the lung or from outside. the tear often occurs at the site of a tiny bullae on the edge of a lung• Clinical S&S:• The typical symptom is a sharp, stabbing pain on one side of the chest which suddenly develops.• The pain is usually made worse by breathing in (inspiration).• Pt may become breathless. As a rule, the larger the pneumothorax, the more breathless .• Pt may have other symptoms if an injury or a lung disease is the cause. For example, cough or fever.
  30. 30. Potential Problems: breathlessness, collapsed lungRadiology:Auscultation: decreased or absent breath soundsPredisposing Factors/Causes: may occur spontaneously in healthy fit people(primary) or in people with lung conditions (secondary)Management:• small pneumothorax is left to heal• Larger pneumothorax can be treated with a ‘Heimlich valve’ which allows air to escape but not to re-enter.
  31. 31. • Chest drains may be used• Physio is based on education in chest drain management• Positioning: lying on good side often most comfortable and best for VA/Q , lying of affected side my speed absorbition of air.• Precautions include avoidance of positive pressure techniques.
  32. 32. Pleural EffusionPrimary Sructures affected:Pleural spacePathological process: excess fluid in pleural cavity caused by disturbed osmotic or hydrostatic pressure in plasma or changes in membrane permeability.Clinical S&S: dull percussion note, SOB, sometimes chest pain
  33. 33. Potential Problems: those of underlying illness, decrease lung functionRadiology: ?fluide line tracking up the pleura laterally?Auscultation: decreassed breath sounds, bronchial breathingPredisposing Factors/Causes: malignancy causes 25% of pleural effusion other causes are heart, kidney, or liver failure, abdominal or cardiac surgery, pneumonia or TBManagement:On large effusions, drainage of chest wall.Smaller effusions may just left under observation.
  34. 34. • Deep breathing exercises can not expand the lungs under pressure of fluid.• People with moderate unilateral effusion may benefit from side-lying affected side upmost as both ventilation and perfusion are greater in lower lung.• Large effusions are likely to show improved PaC2 with effusion downwards to minimize compression of unaffected lung.
  35. 35. Pulmonary EmbolusPrimary Sructures affected: blood vessels in the lungPathological process: blockage of an artery in the lungs by fat, air, a blood clotClinical S&S:include unexplained shortness of breath, problems breathing, chest pain, coughing, or coughing up blood. An arrhythmia (an irregular heartbeat) also may indicate PE. In some cases, the only signs and symptoms are related to deep vein thrombosis (DVT). These include swelling of the leg or along the vein in the leg, pain or tenderness in the leg,• Potential Problems: Severe breathlessness.• Feeling faint, feeling unwell, or a collapse. This is because a large blood clot interferes with the heart and blood circulation, causing the blood pressure to drop dramatically.• Rarely, in extreme cases, a massive PE can cause cardiac arrest, where the heart stops pumping due to the clot. This can result in death, even if resuscitation is attempted
  36. 36. Radiology:?Auscultation: decrease in breath soundsPredisposing Factors/Causes:• most commonly deep vain thrombosis, blood clot breaks off and travels to the lung.• Other causes : Fatty material from the marrow of a broken bone (if a large, long bone is broken - such as the femur (thigh bone).• Foreign material from an impure injection. For example, with drug misuse.• A small piece of tumour (cancer) that has broken off from a larger tumour in the body.Management:• Anticoagulant treatment.• Oxygen given in the early stages to help with breathlessness and low oxygen levels.Hough ( p. 114, 2001) ‘..any active physiotherapy is considered risky until anticoagulation therapy is established.’
  37. 37. CCF/LVF/RVF• CCF • LVF • RVF• Both left and right • Usually caused • Can be caused heart failure with congestions in by coronary by LVF or pulmonary and heart disease – Chronic systemic failing LV forces pulmonary circulation up pressure in hypertension• Pulmonary left atrim and caused by Oedema pulmonary hypoxic (extravascular water in lungs) vasculature = conditions caused by back pulmonary (pulmonary pressure from oedema vasculature failing Left side constrict if 02 • Pitting Oedema reduced)
  38. 38. Smoking• Primary Sructuresaffected:Lungs!• Pathological process: inflammation/damage to cilia/surfactant/Alveoli /Smooth muscle hypertrophy• Increase in secretions but decreased ability of mucocilliary escalator• Alveolar gas exchange decreased/ V/Q Matching• Fibrotic changes from ongoing inflammation• Increase in IgE and IgM – markers of increased sensitivity• Immune responses decreased – more infections• LUNG CLOSING VOLUMES INCREASED – more airway collapse will result• Narrowing/Clogging of arteries/atherosclerosis/increase cholesterol/stiffening arteries
  39. 39. Peripheral Vascular Disease• Chain of events leading to • Risk factors: amputation: • smoking- roughening – Obstruction/resistance/sta means lipids stick more sis of blood – CLOT easily – Pain • BP- stress on – Skin Breakdown vessels/perpetuates – Infection atherosclerosis – Amputation • Diabetes-glucose causes vessel damage/ Plasma viscosity increases/diabetic neuropathy – can’t feel - infections
  40. 40. Peripheral Vascular Disease• Thrombus – occludes • Buerger’s disease – vessel reducing blood vessels become flow= ischaemia inflamed/ clots• Vessel wall form/lumen changes/blood flow obstructed/fibrous stasis/changes in blood tissue forms composition
  41. 41. Ischaemia• Pain • INVESTIGATIONS• Altered sensation – Dopler• Loss of peripheral – Pulses pulses• Decreased muscular strength• Necrosis• Intermittent Claudication
  42. 42. AtherosclerosisPrimary Sructures affected: medium and large arteriesPathological process: become clogged up by fatty substances, such as cholesterol. These substances are called plaques or atheromas.Clinical S&S• Atherosclerosis does not usually produce any symptoms until your blood circulation becomes restricted, or blocked, leading to the onset of cardiovascular disease (CVD). The type of CVD and its associated symptoms will depend on where the blockage occurs.
  43. 43. AtherosclerosisPotential Problems:• peripheral arterial disease: where the blood supply to your legs is blocked, causing muscle pain (intermittent caludication?)• coronary heart disease: where the main arteries that supply your heart (the coronary arteries) become clogged up with plaques• stroke: a very serious condition where the blood supply to your brain is interrupted• heart attack: a very serious condition where the blood supply to your heart is blocked• Angina• AneurysmPredisposing Factors/Causes:High fat diet/cholesterol/High Blood Pressure/Smoking/Diabetes/no exercise/Alcohol/family historyManagement: Medication for BP/cholesterol. Lifestyle changes/Diet/Smoking cessation/Alcohol
  44. 44. Arteriosclerosis and atherosclerosis Arteriosclerosis and atherosclerosis are two terms that aresometimes used interchangeably. However, they are different. Arteriosclerosis is a general term that describes any group ofdiseases where there is a thickening, and a loss of elasticity, of the walls of the arteries it is degenerative Diabetes is a major factor leading to to it arteriosclerosis
  45. 45. Diaphragmatic Breathing This deep breathing is marked by expansion of the abdomen rather than the chest when breathing. It is generally considered a healthier and fuller way to ingest oxygen
  46. 46. ABGS• Low 02 - -Hypoxemia (poor gas exchange)• Co2 – – High Hypercapnia (not breathing enough/poor gas exchange – become acidotic) – Low Hypocapnia (breathing too fast/a lot and blowing it off)
