# Signal-Analysis-for-Patient-Monitoring

A reliable patient monitoring system which analyzes the correlated physiological signals collected from the patient's body, and generates alarms for abnormalities.

The system uses 3 physiological signals collected from the biomedical sensors attached to the patient body.

S1: Heart Rate (HR)

S2: Pusle Rate (PR)

S3: Respiration Rate (RESP)


The following is the design figure used to build the monitoring system where 



The signals are passed through three processing units, called threshold functions, to detect patient abnormalities. 

Each threshold function generates an alarm whenever a data sample of the corresponding signal exceeds a pre-defined threshod. A "1" on the output of each function indicates an alarm and a "0" corresponds to absence of an alarm. 

A majority voter function then generates the final output, based on the value of that the majority of the threshold functions agreed upon.
