connection from the cannula to the Focus unit, make sure that the nasal cannula is positioned
properly on your face, and ensure that you are breathing through your nose. (Your physician may
recommend the use of a chin strap if needed.) If the alarm condition continues, change to another
source of oxygen as available, and contact your Equipment Provider
