Yes a Sherwood Brut works well (I'm not a shareholder in the
company :-). I have rigged a S.Brut (octopus - to have 2
available) to a medical oxygen bottle (we get them with DIN type
fittings,etc.) for on ship/shore emergency treatment. The reason
I chose the S.Brut is because it has a "pin" which can depress
the purge button. If the regulator pressures are reset to
produce a free-flow (with "pin" depressing the purge button) of
approx. 13 l/min, the regulator can provide 100% (virtually) O2.
What for? By inserting a "molded PVC tube" (20mm pipe, approx.
60mm length) into the mouthpiece, the mouthpiece can then be
fitted ("plugged in") to a the face mask of a standard AMBU
Resuscitator Bag - thus giving the patient free flowing 100% O2.
This setup thus provides two treatment options: 1) breathing
directly from the regulator (as per normal demand breathing) and
2) breathing from a face mask, supplied by free flowing O2, e.g.
for unconscious breathing patient, or one that may vomit.
