What is the GCRC? General Clinical Research Center
GCRC monitors patients taking experimental medicines and suffering from rare medical conditions Patients’ vital signs are recorded frequently
3
Problem Statement Nurses periodically take BP, ECG, heart rate, temperature readings Currently printed on paper Nurses must visit at strict intervals, sometimes every 5 minutes Any discrepancy can introduce large and expensive error Manual data entry into server An automatic device would improve reliability of data-gathering process Strict, regular intervals Data is recorded and stored automatically, with less risk of loss or error
4
System Requirements Must trigger & retrieve measurements from monitors
At least every 60 seconds Must upload data to MySQL server via IEEE b Must be simple to use Operated by untrained nurses Must allow setting of measurement interval Allow for taking a measurement at any time Must be easily modified to accommodate new devices Must be highly reliable Loss of any data is unacceptable
