All the mentioned techniques can help decrease a patient's imposed work of breathing during weaning from ventilatory support. Pressure-supported ventilation (PSV) reduces the effort required to breathe, triggering breaths by flow rather than pressure can be more sensitive and less work for the patient, applying CPAP or PEEP can help keep the airways open and reduce the work of breathing, and automatic tube compensation (ATC) adjusts the support to the patient's needs, reducing the work of breathing through the endotracheal tube.
