Non-invasive Non-contact Measurement of Heart Rate and Movement using Ballistocardiography (Bcg)

Dr. Richard Iles, Dr. Joan Lasenby and Dr. Joachim Steiner

Reliable long term non-contact monitoring of apnoeic seizures in childhood is very difficult, particularly at night, causing much family disruption and distress. If these seizures remain unnoticed this may result in sudden unexpected death. In nocturnal epilepsy, including post traumatic and chronic refractory epilepsy, the identification of patients at risk of sudden death is critical.

NoctuSense Ltd has developed non-invasive, non-contact monitoring algorithms, which can be connected to a set of force transducers placed under the mattress. The system is capable of monitoring and analysing seizures as well as disturbances in respiration, heart rate and sleep. This non-contact methodology requires no active participation by the patient, enabling data collection in a cable- and probe-free environment. The resulting data is immediately relevant to paediatric patients and clinicians.

This HTC supported project to validate this valuable tool for non-contact monitoring is being developed by Dr Joachim Steiner, CEO, NoctuSense Ltd, with the aim of undertaking pre-clinical trials, hosted by the Department of Respiratory Paediatrics. A future collaboration with the Cambridge University Department of Engineering’s Signal Processing Group and the Department of Respiratory Paediatrics (EPSRC DTA and FoF grants) is anticipated.
