Myocardial ischemia may occur frequently among ventilator-dependent patients and has been associated with weaning failure. Critical illness polyneuropathy has been cited as a frequent cause of neuromuscular weaning failure among critically ill patients. Unsuspected neuromuscular disease may be an important factor in ventilator dependency. Inability to wean can sometimes be attributed to psychological dependence, poor oxygenation status, or cardiovascular instability (congestive heart failure or ischemia).
