Respiratory disorders À la RNOH
Obstructive airways disease Restrictive lung disease Infections Tumours
Restrictive lung disease Reduced Total lung capacity Vital capacity Functional residual capacity Preserved Airways resistance
Involvement of Nerve supply Chest wall Polio Guillain Barre Cerebral palsy Spinal cord injury Scoliosis Kyphosis Obesity Lung parenchyma Muscles Muscular dystrophies SMA I.P.F. Connective tissue dis. C.F.
Natural history Gradual decrease in VC, FRC Worsening pathology decrease in FRC, Atelectasis work of breathing Nocturnal hypoventilation Daytime hypoventilation Recurrent chest infections Death
Nocturnal hypoventilation airways resistance Intercostal tone Tidal volume Resp. rate REM sleep Morning headaches Restless sleep Daytime sleepiness Enuresis Concentration/ memory difficulties schooling problems
Restrictive respiratory disorders Symptoms Muscular dystrophies Cerebral palsy Scoliosis Spinal cord injury Nothing Dyspnoea on exertion Poor cough Sx Sleep disordered breathing Dyspnoea at rest Signs Underlying disease Respiratory rate Auscultation…Quiet Retained secretions Cyanosis Clubbing
Investigations Bloods. Polycythaemia Blood gas Hypoxia Hypercarbia Chronic respiratory acidosis Early morning sample Chest Xray
Lung function tests Sleep studies Oximetry Transcutaneous Co2 & O2
Lung function tests Peak cough flow > 270 L/min
Restrictive lung disease Two major problems I can’t breath I can’t or won’t cough
Management…breathing Ventilate Invasively Non invasively
Management…….Breathing Long term strategies Maintain range of chest wall movement Frog breathing Inspiratory muscle training Upper limb training
Long term Ventilation When ? Symptomatic Nocturnal CO2 > 10 Kpa 5% study <88% How ? Non invasively Invasively Few hours per night/ all night During day During exacerbations
Sputum Management Assisted coughs Re-Intubation Tracheostomy
Emerson Cough assist Device In-Exsufflator
