Abstract: A package stores at least one electrode pad having a lead. The package includes an interior for storing the pad, and includes a portion that is openable to allow removal of the package from the leads. For example, the openable portion of the package may include a sealed seam through which the lead extends. The operator can peel apart the seam to both open the package and free the package from the lead. Where the pad is a defibrillator electrode pad, the ability to quickly and easily free the package from the lead may save precious seconds during the rescue of a patient in cardiac arrest. For example, freeing the package from the lead typically allows the operator a fuller view of and easier access to the defibrillator and the patient, and eliminates a potential distraction.
