title: A simple and flexible blood cardioplegia delivery system.
abstract: We describe a simple technique for the delivery of high haematocrit blood cardioplegia. The system allows for a user defined, variable concentration of warm, tepid or cold solution to be delivered. The concentration can be varied based upon the pressure regulated flow of blood, and is manipulated by a four variable equation calculated by a spreadsheet formula stored in a hand-held computer. The system provides a very accurate and rapid method of titration and administration of the cardioplegic solution.
