S11) Signs and Symptoms of Respiratory Disease Flashcards
What are the six cardinal symptoms of respiratory disease?
- Breathlesness (dyspnoea)
- Cough
- Chest pain
- Wheeze/stridor
- Sputum
- Haemoptysis
Identify 8 other features in a patient’s history which are relevant to respiratory disease
- Childhood illnesses (whooping cough, wheeze, asthma)
- Occupation
- Pets
- Travel
- Smoking
- Medication
- Allergic disorders
- Psychosocial history e.g. anxiety
List four occupations which are particularly associated with lung disease
- Construction worker
- Farmer
- Coalworker
- Silicon and asbestos work
Which six questions can one ask a patient presenting with breathlessness?
- Precipitating factors?
- Timing?
- Effect of position?
- Speed of onset?
- Duration?
- Exercise tolerance? (assess severity)
Distinguish between the presentations of breathlessness in patients with COPD, heart failure and bronchoconstriction
- Patients with bronchoconstriction: “chest tightness”, “increased effort of breathing”, “air hunger”
- Patients with COPD: “”I cannot take a full breath”, “increased effort”, “unsatisfying breathing”
- Patients with heart failure: “air hunger” or “suffocation”
Identify 7 common causes of dyspnoea
- Asthma
- COPD
- Idiopathic pulmonary fibrosis
- Myocardial dysfunction
- Anaemia
- Obesity
- Deconditioning
What are the different types on breathlessness in terms of speed of onset?
- Instantaneous
- Acute (minutes to hours)
- Gradual (days)
- Chronic (months to years)
What are the causes of instantaneous breathlessness?
- Pulmonary embolism
- Pneumothorax
What are the causes of acute breathlessness?
- Asthma
- Pulmonary embolism
- Pneumonia
- LVF/MI
- Hyperventliation syndrome
What are the causes of gradual breathlessness?
- Lobar collapse e.g. lung cancer
- Pleural effusion
What are the causes of chronic breathlessness?
- COPD
- Idiopathic pulmonary fibrosis
- Bronchiectasis
What is the commonest out-patient symptom?
A cough
Which muscles are important for an effective cough?
- Diaphragm
- Major inspiratory muscles
- Major expiratory muscles
- External intercostals
- Glottis
Describe the physiological mechanism leading to a cough
A reflex arc is initated by mechano- and/or chemoreceptors receptors in the:
- Respiratory epithelium
- Oesophagus
- Diaphragm
Why does vocal cord paralysis cause ‘Bovine’ cough?
- A bovine cough is used to describe the non-explosive cough of someone unable to close their glottis
- This occurs in vagus nerve lesions, associated with dysphonia
Identify 6 respiratory causes of a cough and provide and example for each
- Acute infection e.g. bronchopneumonia
- Chronic infection e.g. bronchiectasis
- Nasal/sinus disease e.g. sinusitis
- Airways disease e.g. asthma
- Parenchymal disease e.g. lung cancer
- Pleural disease e.g. pleural effusion
What are the cardiovascular, gastrointestinal and pharmacological causes of a cough?
- CVS: Left ventricular failure
- GI: Gastro-oesophageal reflux
- Drugs: ACE inhibitors, inhaled drugs
Identify 5 causes of chest pain
- Cardiac
- Pericarditis (relieved by leaning forward)
- Oesophageal pain
- Chest wall e.g. costochondritis, rib fracture
- Pleuritic chest pain e.g. pneumothorax, pericarditis
What is a wheeze?
- A wheeze refers to a noisy musical sound produced by turbulent flow through narrow small airways
- It is mostly expiratory
Identify two clinical conditions which often present with a wheeze
- Asthma
- COPD
Describe the common clinical presentation of a wheeze
- Patients often complain of chest tightness
- Nocturnal wheeze
What is the underlying pathophysiology for a wheeze?
- Bronchial smooth muscle contraction
- Oedema
- Mucus production
Why do wheezes occur during expiration?
The positive intrapulmonary pressure during expiration will exacerbate any narrowing of intrathoracic airways
What is stridor?
Stridor describes a coarse inspiratory wheeze caused by extrathoracic upper airways obstruction e.g. epiglottitis, croup aspirated foreign bodies, extrinsic compression
Describe the underlying pathophysiology of stridor
- The negative pressure in the pleural space during inspiration helps to keep the airways open
- The negative pressure in the upper airways caused by inspiratory air flow leads to stridor
When is sputum production increased?
Increased sputum volume is due to allergy, infection or bronchial irritants
How does infected sputum present?
Infected sputum may be green or yellow
