CoMind 早期可行性研究 (CoMind EFS)
使用 CoMind One EFS 设备开发无创估计颅内压 (ICP) 模型和脑自动调节 (CAR) 新指标的早期可行性研究
The purpose of this research, which has been determined as non-significant risk by the central IRB overseeing the study, is to obtain information to help further develop a machine (a medical device) to measure the pressure around the brain from the outside (this pressure is called intracranial pressure or ICP). Monitoring and managing ICP is an important part of care for patients with conditions such as Traumatic Brain Injury (TBI). However, the current way of measuring ICP requires surgery to drill a hole into the skull, and therefore can introduce additional risks such as infections and pain.
Recent research has shown it may be possible to measure ICP without needing surgery. This technology is in development, but large amounts of data is required to build these new devices.
Through collecting a large database of information from patients who have both the routine surgical device and the research device applied to their head, the research team will work to develop and test an effective and potentially safer way of monitoring patient ICP.

详细说明
A prospective, observational study, determined as non-significant risk by the Central IRB, to assess and improve performance of a non-invasive ICP estimation system. The development of non-invasive systems is intended to replace the need for invasive ICP monitors. Participants serve as their own controls with concurrent, synchronous measurements of ICP (measured invasively as per standard clinical practice), Arterial Blood Pressure (ABP- measured invasively as per standard clinical practice), and measurements of a novel non- invasive cerebral blood-flow index (CBFi) from the CoMind One EFS device. These signals will be recorded simultaneously. The ABP and CBFi will serve as inputs to a model which outputs a non-invasive estimate of ICP, and the invasive ICP signal will be used to supervise and evaluate the performance of the non-invasive ICP estimation model. A large volume of data shall be collected for the purposes of training and testing the non-invasive ICP model. The Sponsor will report limits of agreement (LOA) between data-driven estimates of ICP and the invasively measured signal. In addition, this study will compare metrics built on non-invasive estimation of ICP or CBFi that indicate the state of CAR, and the limits of Autoregulation.

Models trained using CoMind CBFi and ABP will be evaluated based on their limits of agreement (LOA) with invasive ICP.
大体时间:From enrollment to the end of observation (either 3 weeks after removal of the CoMind device or until ICU discharge, whichever event is sooner)

The threshold limit of agreement will be evaluated at three levels corresponding to a model with clinical utility that is optimal, high, or moderate clinical utility. These levels of clinical utility are defined as follows: ● Optimal clinical utility: a model trained using CoMind CBFi and ABP can achieve LOA with invasive ICP less-than or equal to +/-2 mmHg in the range of ICP between 10-30 mmHg, and less-than or equal to +/-4 mmHg in the ranges of 0-10 mmHg, and 30-50 mmHg. ● High clinical utility: a model trained using CoMind CBFi and ABP can achieve LOA with invasive ICP less-than or equal to +/-3 mmHg in the range of ICP between 10-30 mmHg, and less-than or equal to +/-5 mmHg in the ranges of 0-10 mmHg, and 30-50 mmHg. ● Moderate clinical utility: a model that achieves LOA with invasive ICP less-than or equal to +/-4 mmHg in the range of ICP between 10-30 mmHg, and less-than or equal to +/-6 mmHg in the ranges of 0-10 mmHg, and 30-50 mmHg. |
