Help with extracting respiration rate from PPG - LabVIEW

[mrsh]

Hello,

I am having trouble extracting the respiration rate from a ppg waveform.

I have a clean ppg wave.

I have thought about using a collector and then fft in order to attain a 'sine wave' with the respiration data and then using peak detection to get the rate per minute. 

I would appreciate if someone has done this before and could give me advice on how to do this.

I am extremely new to matlab. 

thank you

Well, better learn Matlab, then.  However, if you are interested in using LabVIEW for this project, start by learning LabVIEW.  Look at the Getting Started with LabVIEW entries on the first page of this Forum.  Find yourself someone with some LabVIEW experience and get them to help you get started.  Then just write code, make mistakes, read the Help files, ask your friend for more advice, and in a month or two you'll be cruising along ...
