6. Either
a. Attach cannula to the DISS adapter barb on
the DISS connection provided by health care
provider or
b. Attach a humidifier bottle to the DISS connec-
tion provided by health care provider:
• Fill the humidifier bottle with distilled water
to the proper level as indicated in the humidifier
instructions.
• Attach your breathing cannula to the oxygen
tube connector on the humidifier.
7. Turn the flow control knob clockwise until the
prescribed flow rate (numeral) is visible in the
knob “window” and a positive detent is felt.
Caution: The knob should not be set
higher than the maximum prescribed
flow rate. Out-of specification oxygen
flow will result if the flow control knob is
set between flow rates. An indication of
oxygen flow is the presence of bubbles
in the humidifier bottle.
Caution: To ensure proper flow rate,
verify fittings are tight and leak free.
