I am also interested in the "pulse delivery system" for my project ,
but, I am suspicious of it's function.
(I am an Anesthesiologist and O2 flow systems are part of my specialty)
The way nasal cannulae work is (primarily) not by supplying flow during
inhalation, it is by supplying flow during exhalation. During
inhalation, flow rates at the nose range in the 2-5 liters/sec. This is
about 10 times faster than what the cannulae supply. What the cannullae
do is fill the oro and naso pharynx with O2 which is drawn in via
venturi (it doesn't matter if you breathe via nose or mouth).
I would therefore like to see test results (Partial pressures O2 in
arterial blood or at the trachea) before believing that this system is
