The chart appears to record a blood sugar of about 306 mg/dL at 1 am. Continue glucose checks and any insulin-rate changes strictly according to the hospital’s prescribed infusion protocol and notify the treating team promptly for hypoglycemia symptoms or unexpected readings. The ADA hospital standards advise glucose monitoring every 30 minutes to 2 hours during IV insulin therapy.

Do not reduce the IV insulin rate on your own. If the 1 am glucose is 306 mg/dL, that is still high, and whether to keep, increase, or reduce the 6 units/hour rate depends on the hospital’s written insulin-infusion protocol, the glucose trend, diagnosis, dextrose fluids, potassium, and ketones/acid-base status.

IV insulin requires frequent bedside glucose monitoring, often every 1 to 2 hours, with adjustments only under the prescribed order/protocol.
