ABSTRACT
The multiple parameters that are monitored are blood pressure, temperature,
ECG, and EEG. Our research investigates the potential of WSN
to reliably, wirelessly collect, send and process these multiple
parameters of multiple patients simultaneously, in real-time. This
research succeeds in transforming the traditional individual
patient monitoring apparatus and its requirements into an
apparatus that is capable of reliably monitoring the multiple
parameters of up to six patients simultaneously, in real-time.
Managing interference and ensuring the accurate delivery of the
information to the monitoring system using the most effective
wireless communication technique are the challenges taken in to
consideration.
INTRODUCTION
Continuous monitoring of the health parameters of patients is
one of the major problems faced by the hospital authorities
nowadays. Monitoring should be accurate, precise and carried
out in real time [9]. Current patient monitoring systems consist
of single patient monitoring systems, where sensors are
hardwired to a PC next to bed [7]. Human intervention is also
needed frequently. That is, a nurse will have to frequently
monitor the patient’s health parameters. Employing a multiple
patient monitoring system as oppose to a single patient
monitoring system per patient, would be more cost and power
efficient, and would allow the healthcare professionals to
monitor many patients simultaneously without being in the
same location. So a system that can overcome the above
mentioned problems will really benefit developing countries
like India.
PROBLEM STATEMENT
The problem, that motivated us to develop this system, is the
difficulties for monitoring multiple patients’ health conditions
faced by healthcare providers. In case of a large hospital
where multiple patients need to be monitored simultaneously a
separate monitoring system for each patient is inefficient. By
employing a single system for multiple patients there will be a
huge reduction in cost as well as power consumption. Data
being recorded can be used for further research purposes if
needed. It also provides flexibility to doctors.
RELATED WORK
A two-tier clinical warning system, for hospitalized patients,
was described in [1], which incorporates preventing clinical
deterioration in patients, through early detection and
intervention. Their system consists of an Early Warning
System (EWS) which identifies at-risk patients from existing
real-time Electronic Medical Record (EMR) data, using
machine learning algorithms. A key challenge that they noted
had not been overcome for such applications was to be able
reliably deliver sensor data from mobile patients. This system
focuses on a solution for this problem. Whereas the proposed
system is capable of overcoming this limitation.
CONCLUSION
This patient monitoring system can monitor multiple patient
parameters simultaneously in an indoor scenario.
Experimentation was carried out by taking blood pressure
readings of multiple patients’ [8] .This system is so efficient,
easy to use and handle and hence can be employed in
hospitals. To obtain multiple monitored patients health
statuses and values, doctors or nurses can login to a central
server. It helps in ease of diagnosis. System also maintains the
comfort to the patient as they will no longer need the
traditional monitoring tools of wires and instrumentation.
Wireless communication employed also enables rapid data
transfer offering immediate real-time results in a critical
situation for multiple patients.
