The ivWatch Model 400 with SmartTouch or fiber optic sensor monitored a common peripheral IV site over a 24 hour observation period.

The ivWatch Model 400 with SmartTouch or fiber optic sensor monitored tissue at common IV sites over a 24 hour period.

The ivWatch Model 400 issues red notifications to communicate the need for a clinician to check an IV site. A red notification suggests an increased likelihood that an IV infiltration may be occurring, with a greater likelihood relative to a yellow notification. This measure describes the average number of red notifications issued by the ivWatch device in a given day when monitoring normal, non-infiltrated tissues. The 95% confidence interval for the red notification rate was calculated using a negative binomial regression model.

The ivWatch Model 400 issues yellow notifications to communicate the need for a clinician to check an IV site. A yellow notification suggests an increased likelihood that an IV infiltration may be occurring, although at a lower likelihood relative to a red notification. This measure describes the average number of yellow notifications issued by the ivWatch device in a given day when monitoring normal, non-infiltrated tissues. The 95% confidence interval for the yellow notification rate was calculated using a negative binomial regression model.
