Could a simple neck device help stroke patients survive?

This study is testing a non-invasive device that stimulates the vagus nerve (a major nerve in the neck) to see if it is safe and helpful for people who have had a severe bleeding stroke called aneurysmal subarachnoid hemorrhage. About 25 adults in the intensive care unit will receive the treatment within 72 hours of their stroke. The goal is to see if the device can reduce complications like seizures and improve survival.
