Closed Loop Control: A Newer Mode of Mechanical Ventilation

Closed loop control ventilation is a dual control mode of ventilation, which uses a closed loop control technique. This mode delivers controlled, time triggered, time cycled breaths when patient is not breathing and patient triggered flow cycled breaths when a patient is breathing. If the patient has spontaneous breaths, it delivers flow cycled breaths and allows the patient to trigger and breathe spontaneously, either in between the controlled breaths or fully spontaneously. This mode is pressure limited for control, assist control and spontaneous breath. The pressure will be varying and depends on the target tidal volume and uses auto-flow throughout the cycle. INTELLiVENT is a closed loop mode of ventilation, an advance over the closed loop control mode where the ventilator automatically adjusts settings and optimizes ventilation depending on the target settings and physiological information from the patient
