First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at whether the Dexcom G7 continuous glucose monitor stays accurate in diabetes patients who have poor blood circulation during hospital stays. Researchers compared CGM readings to standard finger-stick blood tests in 60 adults undergoing surgery or in the ICU. Participants wore a blinded CGM device for up to 10 days while receiving usual care.
