Both CPAP with flow-by and low-level PSV are effective alternatives to T tube trials in a rapid weaning protocol. CPAP with flow-by provides a constant positive pressure that allows the patient to initiate spontaneous breaths and reduces the work of breathing. Low-level PSV provides a small amount of pressure support to the patient during inspiration, which helps to augment the patient's own respiratory effort. Intermittent mandatory ventilation is not typically used in a rapid weaning protocol as it involves regularly scheduled mandatory breaths, which can interfere with the patient's ability to wean quickly.
