FDA has cleared a LivaNova 510(k) for its Essenz In-Line Blood Monitor (ILBM) that provides continuous measurement of essential blood parameters to perfusionists throughout cardiopulmonary bypass (CPB) procedures. The monitor is integrated into LivaNova’s next-generation CPB platform, the Essenz Perfusion System, which allows surgeons to access and manage reliable blood parameters directly from the system’s “cockpit,” according to the company. The device provides measured values for oxygen saturation, hematocrit, partial pressure of oxygen and temperature, rather than calculated values for these parameters, it says.

“Existing blood gas analyzers only reflect a patient’s clinical condition at the exact moment a sample is drawn, which can quickly change and become irrelevant,” LivaNova says. “With the Essenz ILBM, perfusionists receive in-line continuous monitoring of the patient’s parameters for the duration of a procedure… Access to accurate, real-time measurements directly from the Essenz Perfusion System allows for quick decisions and tailored care strategies to serve the patient.”
