  • Because the volume-cycled mode ensures a constant minute ventilation despite potentially abnormal lung compliance, it is a common choice as an initial ventilatory mode in the ED. A major disadvantage is that high airway pressures may be generated, potentially resulting in barotrauma . (medscape.com)
