Good morning to all colleagues, researchers and friends.

The ones I know are still available on the internet are capnobase.org and physyonet.org, now I am working and reviewing the signs that are available but if you can recommend more sites I will be grateful.

I am a professor at a Venezuelan University, and I am looking for a database of spirometric signals (in specific, respiratory flow signals) to test an evaluation and analysis program of aging of spirometric signals that I developed for the master's degree.

Once the program is over, I need volumetric signals from healthy individuals to test the routine, I have been searching the free databases published on the Internet for more than a year.

Sincerely, best regards. I thank all of you for the answers or recommendations you can give me.

Sorry if you find errors in my translation.
