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
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
System Requirements Must trigger & retrieve measurements from monitors At least every 60 seconds Must upload data to MySQL server via IEEE 802.11b 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
