Muscle atrophy and diaphragm dysfunction are common with prolonged mechanical ventilation (PMV). Electrical stimulation has been shown to be beneficial in severe chronic heart failure and chronic obstructive pulmonary disease. However, its effect on PMV is unclear. This study examined the effects of transcutaneous electrical diaphragmatic stimulation (TEDS) on respiratory muscle strength and weaning outcomes in patients with PMV.
