The objective of this study was to compare the impact of two modes of ventilation and patient-ventilator interaction on sleep architecture.
New ventilators with more patient-friendly modes of ventilation may cause less patient-ventilator dysynchrony during light to moderate sedation, thereby potentially reducing sedative requirements.
In addition, with the reduced use of sedative agents in the ICU, many critically ill patients are ventilated with modes of ventilation that allow spontaneous breathing activity.
Another important priority for mechanically ventilated patients is lung protection, and nontraditional modes of ventilation that may be implemented to minimize ventilator-associated lung injury include airway pressure release ventilation and high-frequency ventilation.
New modes of ventilation, such as neutrally adjusted ventilator assist, have been documented to reduce asynchrony [ 34].
Proportional assist ventilation, neurally adjusted ventilatory assist and adaptive support ventilation are three novel modes of ventilation, which attempt to optimize patient-ventilator synchrony.
There is, however, no guarantee that a diaphragm is active during assisted modes of ventilation, for patients can trigger the ventilator using secondary respiratory muscles [ 31].
Quality of sleep is negatively affected with frequent patient-ventilator asynchronies and more specifically with modes of ventilation.
Future changes in ventilator management strategies or the introduction of novel modes of ventilation might alter the performance or feasibility of VAC criteria.
New modes of ventilation have been established in recent years to improve patient-ventilator synchrony [ 9].
During assisted modes of ventilation, patients with auto-PEEP often have difficulty triggering the ventilator to initiate a breath.
