Excerpt
Controlled mechanical ventilation may be employed for ventilatory support in patients with respiratory failure when assisted ventilation fails. The purpose of controlled ventilation is to reduce patient respiratory control and effort and to substitute adequate artificial ventilation, thereby providing time for appropriate medical therapy. With improvement the patient's own ventilatory effort may be capable of maintaining normal or clinically stable balance. These principles have been adequately demonstrated in acute ventilatory failure with volume-cycled respirators (1, 2). It was the purpose of this prospective study to evaluate in patients with chronic obstructive lung disease, a group usually difficult to manage during
