All listed techniques can help decrease a patient's imposed work of breathing during weaning from ventilatory support. Pressure-supported ventilation reduces the effort required to breathe, triggering breaths by flow can be more sensitive and less work for the patient than pressure triggering, CPAP or PEEP can help keep the airways open and reduce the work of breathing, and automatic tube compensation helps by adjusting the support to the patient's effort, making breathing through an endotracheal tube feel more natural.
