Shannon's insulin pump beeps, but the screen shows that it is set to vibrate and should not be beeping. Additionally, the pump used is the MiniMed 670G, which uses a different tone for its alarms.
When Shannon's insulin pump beeps, we can see that the screen is displaying a blood sugar level of 5.7 mmol/l. In the U.S., blood sugar is measured in mg/dl, not mmol/l. The screen should instead read 102.
When Shannon's insulin pump is shown, the display indicates that the pump is empty. There is also no alert on the screen, so no reason for the pump to be beeping.
