Abstract

A method for conducting "brain stem early derived potentials" using an inexpensive microcomputer is described. This type of examination is, however, difficult to perform, and is not currently employed in clinical practice. The contribution offered by this data-processing system is emphasized.

A system for logging incontinence events using a simple disposable sensor.

Many elderly people entering residential or nursing care are already incontinent to some degree, relying on incontinence pads to deal with the consequences. A proportion of these people have been shown to exhibit a regular pattern in their incontinence, which opens up the possibility of mitigating the problem by instituting an individual toileting regime for the person. This can reduce their reliance on incontinence pads, both improving their quality of life, and reducing the cost of care. This paper covers the development and evaluation of a sensor for detecting incontinence events, suitable for use in this setting, and describes the design of an associated electronic logger. The devices form part of an assessment system intended to identify a pattern in incontinence where it exists, and to help with the design of the toilet regime for an individual. The requirement is that the system must reliably record incontinence events, and present the information describing them in a manner appropriate to the users of the devices, who are likely to be non-technical and non-specialist.

Issues in using databases of pre-recorded physiological signals to test medical devices.

Bench testing with databases of pre-recorded physiological signals is a common step in the verification and validation of medical devices. For example, in the case of an electrocardiographic (ECG) monitor to be tested, the physiological signals are ECG tracings that have previously been recorded from patients using other ECG monitors. Human overreaders then annotate the tracings to determine the occurrence of significant clinical events such as ventricular tachycardia. These annotations can be used to determine the sensitivity and specificity of the ECG monitor to be tested. This article aims to highlight some issues associated with such bench testing, such as the way the pre-recorded signals are presented to the medical device to be tested, the adequacy of single channel versus dual channel versus multi-channel testing in the bench testing, and the need for the human overreaders and the medical device to use the same set of rules for determining the occurrence of a clinical event. These issues are also applicable to other monitors such as the apnea monitor. Some suggestions for addressing the issues are presented.
