NightWatch
A proven and reliable detection
system for epileptic seizures during sleep.
It detects 9 out of 10 clinically urgent seizures in their early stage. NightWatch is a safe and effective seizure-detection system.
NightWatch is intended for patients, parents/caregivers and care professionals who are searching for an effective way to be warned on time about epileptic seizures during sleep.
NightWatch consists of a comfortable wireless armband that closely monitors heartbeat and motion when the wearer is lying in bed. When NightWatch measures a possibly severe epileptic seizure, a wireless warning signal is sent to a caregiver in another room via the corresponding base station.
IDEAL FOR HOME AND PROFESSIONAL CARE
Benefits of NightWatch
NightWatch is suitable for professional caregiving environments as well as for home use.
NightWatch improves the quality of care and alleviates the task of the caregiving professional on duty. The chances of medical complications can be reduced because adequate help can be offered early on. NightWatch is easy to use, as it does not have to be set up and is directly applicable within existing caregiving processes by linking it to existing nurse call systems.
- Alleviates caregiving duties
- High reliability
- Does not have to be configured
- Suitable for professional and home use
- Works stand-alone or with existing call systems
ALLEVIATE THE TASK OF THE CAREGIVING PROFESSIONAL ON DUTY
Clinical study results
Benefits for healthcare professionals
- Developed by medical specialists, caregivers and patient organizations
- Gives patients more privacy and caregivers more rest
- Works significantly better than alternative detection methods
Clinical study results
In the study, one group of 34 patients who had more than one clinically urgent nightly seizure per month wore the NightWatch arm module for three months, measuring heart rate (photoplethysmography) and motion (3-D accelerometry). All the seizures were classified using video.
Over a total period of 1826 nights 809 major seizures were detected. Major seizures include tonic-clonic seizures, tonic seizures longer than 30 seconds, and hyperkinetic and clustered myoclonic seizures. Compared with the control group, which used a popular bed mat, the bed mat detected 3 out of 10 major seizures while NightWatch detected 9 out of 10.
The attending caregivers participated in the questionnaire and indicated that NightWatch reacts sooner when urgent help had to be offered, is easy to use, and gives more rest/ freedom compared to the control group.
NightWatch detects 1:
- 96% of all tonic-clonic seizures
- 80% of all other clinically urgent attacks, including generalized tonic, hyperkinetic and clustered myoclonic seizures
Epileptic seizures
Worldwide more than 50 million people suffer from epilepsy. About 30% find no relief from epileptic seizures despite taking medication. Nightly attacks can be particularly dangerous to one‘s health.
This condition has a major impact for patients as well as for their environment. It poses risks of accidents and premature death and has social and societal consequences.
