Study Summary

The hypothesis of this pilot study is that nVNS will result in relief of nausea by modulation of vagal nerve activity. nVNS is the first non-invasive, handheld medical device applied on the side of the neck and sends gentle, patented mild electrical stimulation through the skin to activate the vagus nerve. nVNS offers a potential alternative to Gastric electrical stimulation (GES) that could eliminate significant risks of injury or illness or identify likely responders to implantable neurostimulator including implanted VNS (iVNS). nVNS could provide a more effective and safer alternative to the use of traditional rescue medications.

Primary Outcome

Average daily use of rescue medications for exacerbation of nausea/vomiting = sum of nausea medications / number of days with non-missing nausea medication data.
