A code blue in a hospital requires the most immediate, accurate and timely response, and crash cart labels make sure that this precise response is possible. A crash cart must be stocked with all the proper materials, and it must be of utmost certainty that none of the materials stocked are expired. When crash cart labels are implemented into a departments routine, they guarantee that all materials are checked on a regular basis. For example, crash cart labels are imprinted with such information as First drug to expire, Drug Name, Item No. and Check Done On. When a department utilizes crash cart labels, it is ensured that a patients safety is of utmost priority. Crash cart labels are the first step in the proper maintenance of crash carts, but obviously, there are many other supplies that must be maintained in a hospital; for these needs, equipment check labels and tray labels can also be very useful.
