Every high-priority row pairs its red bar with an upward-triangle icon and the word "Urgent", not the colour alone.
the criterion requires a non-colour cue wherever colour is the only thing conveying the alert's meaning.
WCAG 2.2 SC 1.4.1 Use of Color
-
A low-threshold breach (a glucose reading under range) uses a downward triangle and the word "Low", a different shape than the urgent icon, not just a lighter amber.
two alert types that only differ by shade of the same hue remain indistinguishable to many colour-blind readers.
WCAG 2.2 SC 1.4.1
-
A borderline reading inside the normal range still carries a neutral icon and the word "Within range", instead of simply having no marker.
an unmarked row gives no positive confirmation that the reading was checked and found fine, only the absence of a cue the reader may not reliably perceive.
WCAG 2.2 SC 1.4.1
-
The raw reading (178/102 mmHg, 62 mg/dL) stays printed at full size on every row, not replaced by the urgency word alone.
the badge answers whether a row needs attention now; the number is what the clinician needs to actually assess and act on it.
Clinical usability - RPM alert design

An alert queue that only turns a row red doesn't tell a colour-blind clinician which patient needs attention first.
