Although this technology is becoming more sophisticated,
there are still concerns with quality of medical data,
security of patient medical information, stability of complex
monitoring systems, usability, acceptability by the medical
staff as well as patients and the frequency of false alarms
being generated. However, a number of studies have been
conducted in the last two decades to reduce these concerns.
For instance, Imhoff and Kuhls [29] have identified that up
to 90 % of all alarms in critical care monitoring, are false
positives. Others researchers have also proposed further
measures to further reduce these false alarms, which include;
modifying the range of parameters, reducing threshold
values, or incorporating a time delay in generating the
alarms [30–32]. In the following sections there will be a
discussion of the latest health monitoring systems and a
critical analysis of the common issues faced by today’s
healthcare applications.
