Resp Flashcards
Signs of COPD in the hands
CO2 retention flap
Tar staining
Bounding pulse
Signs of hyper expansion seen in a patient with COPD
↓ cricosternal distance
Loss of cardiac dullness on percussion
Palpable liver edge
What are signs of cor pulmonale?
↑JVP Left parasternal heave: RV hypertrophy LoudP2±S3 MDM of pulmonary regurg Ascites and pulsatile hepatomegaly Peripheral oedema
Definition of COPD
Is used to define two conditions:
Chronic bronchitis: Cough productive of sputum on most days for ≥3mo on ≥2 consecutive years
Emphysema: Histological description of alveolar wall destruction with air collapse and air trapping
4 features you would see on spirometry of a patient with COPD?
↑ TLC and residual volume (RV)
FEV1 <80%
FEV1:FVC <0.7
↓ transfer factor
How can you determine the prognosis of a patient with COPD?
Bode index
Looks at: BMI Obstruction: FEV1 Dyspnoea: MRC score Exercise capacity: 6 min walk
Gold Classification COPD
Global Initiative for Obstructive Lung Disease) - allows you to tailor therapy to the patient
Looks at:
mMRC dyspnoea score (modified medical research council)
Airflow limitation
No. of exacerbations per year
Conservative management of COPD (4)
MDT
GP, dietician, physio, resp physician, specialist nurses
Regular review 1-2x / yr
Smoking Cessation: single most important intervention
Specialist nurse and support programme
Nicotine replacement therapy
Varenicline: partial nicotinic agonist
Pulmonary Rehabilitation Therapy
Tailored exercise programme
Disease education
Psychosocial support
Co-morbidities
Nutritional assessment and dietary support
CV risk Mx
Vaccination: pneumococcal and seasonal influenza
Medical Management of COPD
Principal Therapies
Anti-muscarinics: short- or long-acting
β-agonists: short- or long-acting
Inhaled corticosteroids: in combination ̄c β-B
Other Therapies Theophylline or Roflumilast: PDIs Carbocisteine: mucolytic Home emergency pack for acute exacerbations LTOT
Surgical Management of COPD
Used for recurrent pneumathoraces or large bullae
Bullectomy
Lung reduction surgery (removing damaged parts of the lungs)
Definition of asthma
Episodic, reversible airway obstruction due to bronchial hyper-reactivity to a variety of stimuli.
Conservative management of Asthma
M TAME
General MDT: GP, specialist nurses, respiratory physician Technique for inhaler use Avoidance: allergens, smoke (ing), dust Monitor: Peak flow diary (2-4x/d) Educate Liaise ̄c specialist nurse Need for Rx compliance Emergency action plan
Management of acute asthma exacerbations
Immediate
- Sit-up
- 100% O2 via non-rebreathe mask (aim for 94-98%)
- Nebulised salbutamol (5mg) and ipratropium (0.5mg) 4. Hydrocortisone 100mg IV or pred 50mg PO (or both) 5. Write “no sedation” on drug chart
Life threatening
Inform ITU
MgSO4 2g IVI over 20min
Nebulised salbutamol every 15min (monitor ECG)
IV Rx if No Improvement in 15-30min: Nebulised salbutamol every 15min (monitor ECG) Continue ipratropium 0.5mg 4-6hrly MgSO4 2g IVI over 20min Salbutamol IVI 3-20ug/min Consider aminophylline Load: 5mg/kg IVI over 20min Monitor Levels ITU for intubation
What are some of the causes of PF?
Upper (PENTA): Pneumoconiosis: Coal, Silica Extrinsic allergic alveolitis Negative, sero-arthropathy (ank spond) TB Aspergillosis : ABPA
Lower (STAIR): Sarcoidosis (mid zone) Toxins: BANS ME Asbestosis Idiopathic pulmonary fibrosis Rheum: RA, SLE, SS, Sjogren’s, PM/DM
TOXINS (BANS ME): Bleomycin, Busulfan Amiodarone Nitrofurantoin Sulfasalazine MEthotrexate
Spirometry results for PF?
↓TLC ̧ ↓RV, ↓FEV and ↓FVC
FEV1:FVC >0.8
↓ transfer factor
Management of PF
MDT: GP, pulmonologist, physio, psych, palliative care,
specialist nurses, pts. family
Anti fibrotic: e.g. perfenidone
Rx specific cause:
EAA: steroids
Sarcoidosis: steroids
Connective tissue disease: steroids
Supportive care:
Stop smoking: single most beneficial strategy Pulmonary rehabilitation
LTOT
Symptomatic: anti tussive such as codeine phosphate
