Disorders of the respiratory system Flashcards
What groups can respiratory disorders be split into and what are they associated with?
- Upper respiratory tract = associated with inspiratory dyspnoea and an externally audible noise
- Lower respiratory tract = associated with expiratory dyspnoea and wheeze generally audible on thoracic auscultation
- Extrapulmonary disease
What are the components of the upper respiratory tract?
- Nasal cavity
- Pharynx
- Larynx
- Trachea
What are some clinical signs associated with nasal disease?
- Sneezing
- Snorting
- Facial swelling
- Facial rubbing
- Dyspnoea
- Nasal discharge
What could nasal discharge possible look like?
- Serous
- Mucoid
- Mucopurulent (green)
- Bloody
What are some possible causes for nasal disease?
- Viral/bacterial/fungal
- Allergies
- Neoplasia
- Ethmoid haematoma
- FB
- Polyp/cysts
- Trauma
- Coagulopathy
- Dental disease
- Sinusitis
- Dacryocystitis (infection of the nasolacrimal sac)
What diagnostics can be done for a patient with suspected nasal disease?
- History and clinical examination
- Blood tests (haematology, biochemistry, clotting profile)
- Imaging (X-rays/CT/MRI/Rhinoscopy/Endoscopy)
- Bacteria and fungal culture
- Nasal flush for cytology
- Biopsy and histopathology
What treatment and nursing care can be done for a patient with nasal disease?
Dependent on cause
- Barrier nurse and isolate (if infectious)
- Monitor vitals and clinical signs including comfort
- Cleaning/grooming including nasal orifices (apply vaseline)
- Assist with feeding
- Humidifier may be required
- Medication under VS direction (ABs for bacterial infections and antifungals for fungal infections)
- Assist with surgical procedure/removing FB
What are some common causes of laryngeal disease?
- Persistant barking
- Respiratory tract infections
- Paralysis of arytenoid cartilage
What are some clinical signs of laryngeal disease?
- Change in vocal ability
- Coughing/gagging
- Stridor (audible whistling noise) on inspiration
- Exercise intolerance
- Cyanosis
- Hyperthermia
- Dyspnoea (often with paradoxical abdominal movement)
What diagnostics can be done for a patient with suspected laryngeal disease?
- History
- Clinical examination
- Endoscopy
What stabilisation and management his required for a patient with laryngeal disease?
- O2 therapy
- Sedation and rest (reduce stress and inspiratory effort)
- Cooling
- Tracheostomy (severe cases)
- Hobday in mild cases
- Tie-back in severe cases
- Swap collar for harness
What is epiglottic entrapment?
Aryepiglottic folds become abnormal and envelopes the apex and lateral margins of the epiglottis
What clinical signs may be seen with epiglottic entrapment?
- Stridor (audible whistling noise) on inspiration
- Dyspnoea
- Coughing
- Cyanosis
What diagnostics can be done for a patient with suspected epiglottic entrapment?
- History
- Endoscopy
What stabilisation and management is required for a patient with epiglottic entrapment?
- Surgical correction
- Systemic anti-inflammatories
- ABs
What does the lower respiratory tract consist of?
- Bronchi
- Bronochioles
- Alveoli
Orthopnoea
dyspnoea or shortness of breathing in lateral recumbency (usually improves in sternal recumbency)
What is acute respiratory disease?
- Interruption or failure of normal respiratory function
- Reduced O2 to the circulation
- Increased CO2
