Use the BGL as one part of the patient assessment. Compare it with mental status, symptoms, skin signs, history, medications, and ability to swallow.
Low
< 70 mg/dL: May fit confusion, weakness, diaphoresis, shakiness, combativeness, seizure, or unconsciousness. Follow local protocol.
Reference band used by the app
70–180 mg/dL: A value in this band may not explain an altered patient. Continue evaluating stroke, overdose, hypoxia, infection, trauma, seizure, and other causes.
High
181–350 mg/dL: Assess symptoms, hydration, respiratory pattern, history, and the full patient presentation.
Critical / concerning
> 350 mg/dL: May be associated with significant dehydration or diabetic emergency. Provide supportive care and transport per protocol.
Do not give anything by mouth when the patient cannot protect the airway or swallow safely. If a reading is an error or does not match the patient, clean and warm the finger as appropriate, obtain an adequate sample, and repeat according to training and device instructions.
Educational practice only. Follow approved course instruction, local protocols, medical direction, and scope of practice.
