Why Does a Ventilator Cause Edema?
Disease description:
My friend suddenly lost consciousness and is now on a ventilator. Swelling of the throat was discovered—why would the ventilator cause this edema?
Doctor's answer (2)
Dr. Hao Xingliang
During mechanical ventilation, endotracheal intubation is performed; the endotracheal tube inserted into the trachea can irritate and abrade the pharyngeal tissues, leading to congestion and swelling of the local tissues—resulting in pharyngeal edema. Prompt administration of anti-inflammatory and diuretic medications can help reduce and gradually resolve the edema. Concurrently, enhanced nursing care is essential, including maintaining oral and pharyngeal hygiene.
