I saw this video online recently about building a radar respiratory rate monitor. Counting respirations in hospitals is a pain because there isn't anything on most dynamaps to measure respirations and it is normally done by eye which is no good if the patient breathes through their nose.

 

I don't know exactly how it works, but I think there would have to be more tests for reliability. How sensitive is the sensor? Is there any chance that it could not catch very, very light breathing?

Fiveworlds: Great idea. You can monitor all patients 24-7 instead of periodic rounds. Whether breathing through the mouth or nose one can count respiration by watching the chest rise and fall. One cant breathe without the chest moving.Liked to have had it at Camp Gary. Not enough orderlies.They need one to monitor temps and pulse as well.
