I am writing code at labview to display CO2 and SpO2 as waveforms. Data is traveled in form of RS 232. I am confuse with how will I splite the data CO2 and SpO2 once I receive into labview.
Please help me through this.

We need more information to help you with your issue. Are you using an instrument which communicates with serial rs232? Is the data coming through as binary format? can we use instrument commands? ect?

I am using USB serial converter b/w Patient monitor and PC. Data is traveling in packets. Main problem is making PC to receive data from patient monitor which is in serial format. I need to display data at labview. I am attaching menu of patient monitor as well. PLEASE Help.

If you have not yet looked at the Serial Communication examples then you should do so right away. If you navigate to the NI Example Finder through the help (menu in labview)» find examples. Here you can click on the search tab and type serial for keywords. Alternatively you can navigate to serial via the browse tab under: hardware input and output>>serial.
There will not be an easy way to communicate with you device because it does not seem to show up in the Instrument Driver Network (www.ni.com/idnet). You can first try the Basic Serial Write and Read.vi (example) and try sending and receiving basic serial commands. It is likely that your instrument uses its own serial communication protocols. Check out getting started guides.
Furthermore, you need more information then what you have posted on the forum. You need to know specifics about the serial communication and whether it uses the standard protocol: Baud Rate/ Data Bits/ Parity/ Stop bits/ Flow control/ ect. This information should be supplied by the manufacturer.

Did you have any luck?
I have just started a project where I will do the same as you. I am going to write LabVIEW code to interface with a Phillips Intellivue patient monitor. As you mention, the data is in a special serial format (MIB Data Export Format). And the format is pretty complicated (as seen in that PDF document).
Did you have any success?
As an alternative, you could try using Trendface or Datacaptor (commercial applications). But I want flexibility. So I am looking to write my own code.
