When might a BLS provider use a glucometer?

A Basic Life Support (BLS) provider would use a glucometer primarily to check the blood glucose level of a patient. Monitoring blood glucose levels is crucial in various emergency situations, particularly when a patient exhibits signs of hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar). By assessing the blood glucose level, the provider can identify whether the patient requires immediate glucose treatment, which is critical for preventing further medical complications.

Using a glucometer allows the EMS provider to obtain pertinent information that helps guide further treatment decisions and interventions. For example, if a patient is experiencing altered mental status, dizziness, or weakness, determining their blood glucose level can aid in diagnosing conditions such as diabetes or an insulin reaction. Thus, checking the blood glucose level is a vital action that supports effective patient care in emergency settings.
