The choice of appropriate ventilatory equipment depends on a number of crucial factors:
• The degree of ventilator dependency • Underlying pathophysiology and likelihood of progression • Level of general mobility/dexterity/muscle strength • Comfort and ease of use • Staff familiarity with equipment • Patient and family choice • Cost.
