An '''e-cylinders''' is a type of gas cylinder used for storage and containment of gases. In anesthesia, e-cylinders are typically used for delivery of fresh gases to the anesthesia machine in case of pipeline gas pressure failure.

An e-cylinders is a type of gas cylinder used for storage and containment of gases. In anesthesia, e-cylinders are typically used for delivery of fresh gases to the anesthesia machine in case of pipeline gas pressure failure. E-cylinders uses the pin index safety system (PISS) that ensures the correct placement of cylinders of a particular type of gas into the right location in the anesthesia machine.
