Y1 - 2013 N1 - T2 - Principles and Practice of Mechanical Ventilation, 3e AB - Controlled mechanical ventilation (CMV) is traditionally provided via an artificial airway to completely unload a patient’s work of breathing and assure adequate gas exchange during the acute phase of respiratory insufficiency, until the underlying respiratory function has resolved.1 The criteria used to determine when to terminate mechanical ventilation are essentially based on the clinical, and often, subjective assessment of the intensive care physician or on standardized weaning methods.2,3 The actual process of weaning the patient from CMV is carried out by allowing spontaneous breathing attempts with a T piece or continuous positive airway pressure (CPAP) or by gradually reducing mechanical assistance.4,5 Not surprisingly, gradual reduction of partial ventilator support benefits only patients who have difficulty in sustaining unassisted breathing.4 Although introduced as weaning techniques, partial support modes have become standard methods of providing primary mechanical ventilatory support in critically ill patients.
