Cardio Pathologies (COPD) Flashcards
What is COPD
COPD is characterised by airflow obstruction which is: progressive in severity doesn’t change markedly over several months
What conditions come under COPD
Chronic bronchitis, emphysema, chronic asthma
What’s normal airway clearance
Airways are lined by cells which produce mucus, tiny hairs called cilia which beat mucus traps dust particles and bacteria, cilia move mucus until it reaches throat and we swallow or cough it
What can go wrong with the normal airway
In COPD and bronchiectasis excess mucus is produced, mucus is thicker and stickier, cilia unable to beat, smoking paralyses cilia so dust gets trapped in airways, mucus build up provides warm environment for bacteria so infections develop
What is chronic bronchitis
Bronchi become inflamed, inflammation causes mucus production, narrows airways, increased sputum and it’s difficult to clear, wheezing common after coughing, reduced air enters lungs
What’s emphysema
Alveoli of lungs become inflamed and loose elasticity over expand and lose ability to fill up and contract
As air fills up sacs some rupture, sa reduced when you breathe out trapped air isn’t released so breathing is more difficult
What’s chronic asmtha
Increase in airway obstruction caused by various stimuli = increased air way resistance
Can be reversible
Airways sensitive can become irritated, inflamed and narrow reduced air flow through air ways can become chronic due to fixed airway damage (therefore COPD)
Causes of COPD
Smoking, occupational exposure, alpha 1 atrypsin deficiency, social delreigation
What would you observe in someone recently diagnosed with COPD
Morning cough, winter chest infections, breathless when exercising, spirometry reduced
What would you observe in someone with moderate COPD
Cough, wheeze, SOB, wheeze, barrel chest, flat diaphragm on CXR
What would,you observe in someone with severe COPD
Cyanosis, weight loss, raised JVP, peripheral oedema
What objective tools could you use for someone with COPD/ chronic bronchitis/ emphysema/ chronic asmtha
CXR Oxygen sats Ausculatation Borg breathlessness scale Exercise testing Spirometry if diagnosed recently
What treatments can physios use for COPD/ chronic bronchitis/ chronic asmtha/ emphysema
Smoking cessation
Pulmonary rehab: exercise, education, self management, diet and lifestyle modifications
