John,
I think Esat, is getting + 02 pressure, confused with the constant-flow
outlet on a 02 set that delivers around about 10 Lt / min to a strapped on
face mask, when the patient breathes in they get a lung-full of 02,
otherwise the 02 just runs away - it's not forced at pressure down the
lungs. The mask can be used in this set up to enable enriched air EAR on an
unconscious patient
