Clinical signs and symptoms of respiratory disease Flashcards
What diseases affect the airways?
- Asthma
- COPD
- Bronchiectasis
- Cystic fibrosis
What diseases affect the lung parenchyma?
- Pulmonary fibrosis
- Pneumonia
-TB
What diseases affect pulmonary circulation?
- Pulmonary embolism
What diseases affect the pleura?
- Pneumothorax
- Pleural effusion
What diseases affect chest wall shape and the neuromuscular system?
- Kyphoscoliosis
- Myasthenia gravis
What are the key signs and symptoms of respiratory disease?
- Severely breathlessness/feeling of suffocation
- Chest pain
- Cough
- Sputum (if green = presence of neutrophils)
- Haemoptysis
- Breath sounds
What is dyspnoea?
- Symptom rather than a sign
- Subjective awareness of increased effort of breathing
- Very common
- Common to respiratory conditions
- But not specific e.g. anaemia, heart failure, obesity
How should you further explore dyspnoea?
- Onset, timing and duration
- Exacerbating factors
- Progression
- Severity
What are the mediastinal causes of chest pain?
- Acute coronary syndrome
- Pericarditis
- Oesophagitis/GORD
- Aortic dissection
What are the pleural causes of chest pain?
- Infection (causing pleurisy)
- Pneumothorax
- Pulmonary embolism (causing infarct)
What are the causes of chest wall pain (including skin)?
- Rib fracture
- Costochondritis
- Shingles (varicella zoster virus)
What is important about the location of chest pain?
- Central vs non-central
- Cardiac vs pleuritic
What is pleuritic chest pain like?
- Due to irritation of parietal pleura
- Thoracic wall or shoulder tip pain (referred via intercostal nerve/phrenic nerve)
- Sharp, well localised
- Worse with coughing and breathing in
What is a cough?
- A short, explosive expulsion of air
- Important protective mechanism
What stimulates a cough?
- Triggered by stimulation of mechano- and/or chemo-receptors within airway
- By any source of irritation e.g. inflammation, foreign body
Outline the cough reflex
- Cough stimulus
- Larynx, trachea, bronchi
- Afferent limb = vagal nerves
- Central control cough centre
- Efferent limb = motor nerves
- Laryngeal and respiratory muscles
- Cough
What is cardiac chest pain like?
- Visceral pain
- Dull, central, tight or crushing in nature
- Radiate to neck, jaw, shoulders and/or arm
After an initial inhalation, which mechanisms are included in a cough?
- Adduction of vocal cords
- With contraction of internal intercostals and abdominal muscles
- Increases intrathoracic pressure
- Followed by abduction of vocal cords
