The improvements include the upgrade from RS232 connectivity to USB Bridge, provision for wireless interface, LCD upgrade and so on. And, the modifications include the hardware and software changes made to the previous design for better performance in terms of current consumption. A detailed current consumption analysis of the pulsoximeter board along with the current profile has also been discussed in this document. A custom LabVIEW GUI has been developed for this application to display the heart signal, heart rate and % SaO2 number. All the necessary files and steps to get this GUI up and running have been provided along with this report.
