7. Confirm secure connection of the male luer-lock fitting of the pressure monitoring line to the pressure
monitoring site at the top of the heat exchanger. Rotate the three-way stopcock to measure pressure from
the heat exchanger.
NOTE: If the pressure monitoring site on the heat exchanger is not used, place a nonvented cap on this
port.
8. Confirm secure connection of the pressure relief line to any available luer port on a vented cardiotomy
reservoir.
NOTE: MYOtherm XP
the pressure relief line. The CSS instrument has built-in systems to guard against overpressurization. The
line connected to the pressure monitoring port may be connected to a port on a cardiotomy reservoir for
priming/recirculation purposes.
NOTE: The pressure relief and pressure monitoring lines are preattached to the heat exchanger.
9. Attach the oxygenated blood line to the extracorporeal circuit and clamp securely prior to priming the
extracorporeal circuit.
10. Securely close both clamps and insert the first IV spike of the cardioplegia line into the appropriate bag/
bottle containing the cardioplegia/priming solution. If only one spike is to be utilized, the second line clamp
should be moved down as close as possible to the "Y" Connector and securely clamped. If both spiked
lines are to be used, the second line clamp should be moved up and securely clamped next to the spike
to facilitate the prime.
WARNING: Use of a bottle for cardioplegia solution requires the presence of a functional standard air vent
in the bottle that extends at least 2.5 cm (1 in) above the top of the cardioplegia solution fluid level.
11. Attach the temperature probe to the temperature monitoring adaptor at the outlet port of the heat
exchanger.
