assessment of hypoventilation - early moring abg , overnight oximetry, trancuatoin co2 monitoring
flureoscopic screein of diaphromas
are these conditons obstucive or resticive
restricitve
treatmenf for ventilary fialues
wieght loss, non invasive venitlation, oxyeen therapy if non hypoxic drive
tracehostomy ventilation
