Wireless Vital Signs Monitoring

The process of manually charting patient's blood pressure, pulse rate, respiration rate, SpO2 are laborious and tedious. It also opened up for error in charting for each patient where the charting error could be onto a wrong patient's record or vital signs were not timely charted accordingly. Using RFID-enabled technology on-line vital signs monitoring is an approach towards minimising some of these errors and help manage the process in a better way.

Here we can utilize an electronic bridge that serves as a medical device interface with direct connection to non-invasive blood pressure devices, SpO2, etc via RS232 serial port and wirelessly uploading the data onto the central clinical charting system or a dedicated Vital Signs Dashboard. The electronic bridge makes use of the WLAN 802.11 b/g, ISM band radio technology. It receives the vital signs data through the RS232 port and upload the data to the central clinical charting system . Each patient's record is recognised by the barcode of the patient's wrist which is entered into the system by a barcode scanner. Nurses can observe and make assessments of the patients before uploading data onto the central clinical charting system. Uploading of the patients' vital signs measurements can also be done automatically with the system or at user-defined intervals. Hospital clinical staff will be able to view the patient's vital signs through its wed-based system. The ultimate aim of the system is the relieve nurses from the menial tasks but on the other hand provide accurate data capturing of the patients vital signs.
