I want to find all instances of O2 Saturation (Group:O2 Sat) blood gas results in the i2b2 database, with a value between 10 and 20%, at any time, with a specificity scale of 0, and with a total item occurrence of 1. The query should be applied to panel 1 with an accuracy scale of 100 and the item should be classified as an ENC (Encounter). The icon used for this item should be FA, and the tooltip should display "Labtests \ Chemistry \ Blood Gases \ O2 Saturation (Group:O2 Sat)".
