Priming CPM

Priming procedure

Power ON the CPM, wait about 30 seconds, and select the Califia Patient Module simulation mode in the Opening Screen, then press Continue to step into either CPB or ECMO per your preference.

Prepare the CPM with tubing connections as shown in the figure below.

  • The Arterial and Venous ports attach to ½” or ⅜” tubing.
  • The Cardioplegia and Vent ports attach to ¼” tubing (not shown).
  • Make each tubing segment at least 6” in length. Clamp all tubing to avoid leaking water.

CPM Priming Process

Refer to the Figure above to prime the CPM.

Connect a tubing circuit with a bridge section between the Venous and Arterial ports. Clamp the segments connected to the pump.

Pour about 2.5 Liters of water into the CPM’s reservoir.

  • Notice patient’s vitals such as arterial pressure and central venous pressure increase in value; in essence, the vitals correspond to those of a living patient.
    • Ensure all tubing is clamped to avoid any water leak

Open the side door to align the silicon tubing in the peristaltic pump’s raceway. Close lid and side door.


In the Instructor’s Panel » Califia Controls section, press the Pressurize button to operate the peristaltic pump and prime the CPM.

After one minute of pressurizing, set the Drainage Cannula value to 5%.

After an additional minute, complete the priming process by returning the Drainage Cannula value to 100% and pressing the Pressurizing button to stop the peristaltic pump.

NOTE: To achieve high flow rates at lower pressure place the CPM at least 18” higher than the venous reservoir (CPB) or pump inlet (ECMO).
