I2: Contraindications
- Users who have undergone surgery to cut the vagus nerve (cervical vagotomy);
- Users diagnosed with severe low resting heart rate;
- Users with a permanent (that cannot be removed before using Nurosym) implanted metallic or electronic device or jewellery at close proximity to the ear tragus;
- Pregnant women.
Below are listed situations that are also contraindications unless the user receives a different health opinion on the device use by their health professional and is under the supervision of a health professional while using the device. If you fall under one of these categories, your health professional might advise whether, in your specific case, the device is safe to use, potentially following certain precautions or under specific supervision:
- Users with any active implanted device (including electronic and/or wearable devices) e.g. cochlear implant, cerebral shunts, invasive vagus nerve stimulators, pacemakers or non-active but potentially interacting with the nervous system (e.g. metal implants);
- Users with known severe coronary disease or recent heart attack (within 5 years);
- Paediatric users
- Pregnant women have not been evaluated in scientific studies.
- Both paediatric users and users with pacemakers have been enrolled in scientific studies with Parasym technology, and no device related adverse events or interferences have been observed so far in the scientific setting.
