Diabetes Sentry Device

Get the Low-Down

Take a moment to peruse some of the frequently-asked questions regarding the Diabetes Sentry device.

The Diabetes Sentry is a nocturnal hypoglycemia symptom alarm worn on the wrist which detects the two most common symptoms of Hypoglycemia, an increase in perspiration and/or a drop in skin temperature. When either one or both of these two symptoms occurs, a loud audible alarm is sounded.

The Diabetes Sentry utilizes advanced sensors that make contact with the skin and continuously monitor the status of an individuals’ body chemistry. If the sensors detect a change in the initial automatic preset levels established when the Diabetes Sentry was first worn by the individual a loud audible warning alarm will sound. When this occurs it is recommended that the individual perform a blood test to determine if in fact a persons blood sugar levels are trending dangerously low.

NO. The Diabetes Sentry is only monitoring for the symptoms which may accompany hypoglycemia, namely perspiration and/or a drop in skin temperature. Either of these symptoms or a combination of both will trigger the alarm. If an alarm sounds you must do a blood test to determine blood sugar levels. You can not be sure that the alarm is sounding due to hypoglycemia, as perspiration of any kind will cause an alarm to sound, and some people may perspire at night for other reasons.

Yes. These are called “false positives” and occur whenever perspiration is present or a drop in temperature occurs. This may happen for various reasons.

YES. Although children commonly perspire at night for reasons other than hypoglycemia, causing sometimes frequent "false positives". In addition, if your child has petite wrists, the device might not fit properly. Please feel free to call us with specific questions.

From the clinical studies done on the original Diabetes Sentry we know that when hypoglycemia was confirmed as being present the Diabetes Sentry alarm sounded 90% of the time. The 10% of the time that the alarm did not sound was attributed primarily to human error or the symptoms for hypoglycemia did not present themselves.

No. The Diabetes Sentry will only work for those people who exhibit the symptoms of hypoglycemia, perspiration and/or a drop in skin temperature. The Diabetes Sentry is designed for insulin dependent diabetics who have frequent episodes of hypoglycemia and have had enough bad experiences over a reasonable period of time, so that they are very, very aware of the dire consequences of a nocturnal episode.

No. Straps have Velcro closures and can be adjusted for fit, simply and comfortably.

Not totally. The Diabetes Sentry is designed to withstand perspiration and may be cleaned with a wet cloth and towel dried, but should never be immersed in water (i.e. shower or bath).
