Key result
The PRONTO procedure allows for the rapid replacement of a failed oxygenator by inserting a second one in parallel without interrupting blood flow to the patient during cardiopulmonary bypass.
The PRONTO procedure provides a simple and rapid method to replace a failed oxygenator during cardiopulmonary bypass without interrupting blood flow.
May facilitate uninterrupted CPB during oxygenator failure; leaves open prospective validation of safety and reproducibility.
We present here a technique to replace a failed oxygenator by inserting a second oxygenator in parallel (PRONTO) within the cardiopulmonary bypass (CPB) circuit. Oxygenator failure is a potential hazard that may result in patient injury or death. Although failures are rare, safety surveys conducted over the last 25 years suggest that the incidence of oxygenator failures is on the rise. This emergency procedure may be easily applied to any standard CPB circuit with a few minor alterations. The technique is simple; it can be carried out rapidly. An important advantage of this technique is that it may be executed without interrupting blood flow to the patient, which may reduce the incidence of patient injury or death.

Groom et al. (2002) studied Oxygenator failure during cardiopulmonary bypass. PRONTO procedure (inserting a second oxygenator in parallel) was evaluated. The PRONTO procedure allows for the rapid replacement of a failed oxygenator by inserting a second one in parallel without interrupting blood flow to the patient during cardiopulmonary bypass.
