A controlled access anesthesia cart has at least one drawer or compartment for storing general-use anesthesia items, and at least one drawer or compartment for storing controlled substances, e.g., narcotics. An RFID reader in the cart senses for RFID signals, and if a portable RFID transceiver is in range of about 3 meters of the cart, the compartments in the cart are unlocked for access. The anesthesiologist needs to enter a pass code for access to the controlled substances compartment(s). The compartments then remain unlocked so long as the portable RFID transceiver is present. When the portable transceiver is out of range, the cart immediately relocks the compartments automatically. |
