Essenz In-Line Blood Monitor

Accurate in-line blood monitoring at your fingertips

Essenz Patient Monitor
Essenz In-Line Blood Monitor, powered by B-Capta sensing technology, is the Ready-To-Go blood monitoring system integrated into the Essenz™ Perfusion System and its cockpit, for accurate measurement of essential patient blood parameters.

Flexible and Efficient

  • Integration in the Essenz cockpit means there is no need for external monitors and holders that may obstruct the perfusionist's view during the procedure
  • Ready-to-Go system does not require any calibration procedure to set the device measurements, allowing the perfusionist to save time during device set up, especially in emergency cases
  • No need to purchase different sensors for adult and pediatric procedures, as one sensor fits all cuvettes sizes


  • Intuitive user interface, with easy parameter, sensors and settings configuration, leading to a short learning curve
  • Cockpit provides one central view to control the device and check all perfusion and patient parameters in the right place at the right time, minimizing distractions
  • Measured values are automatically transferred to the Essenz Patient Monitor, enabling the perfusionist to maintain accurate perfusion procedure records


  • No calculated parameters: Essenz In-Line Blood Monitor only provides measured values for the accurate monitoring of Sat, HCT, pO2 and Temperature
  • Continuous in-line monitoring of the patient’s blood parameters allows the operator to quickly react to changes and improve patient outcomes
  • Accurate sensing technology to support the implementation of Goal-Directed Perfusion (GDP) therapy through the Essenz Patient Monitor

Safe and reliable

  • Optical based technology provides high levels of accuracy and reliability even in long and complex cardiopulmonary bypass procedures
  • The only continuous blood monitoring device that works within the CLIA guidelines and provides parameter values in line with Hospital ABL, even prior to alignment1
  • State-of-the-art safety precautions
    • Integrated warning system: visual and audible indicators when parameters fall outside thresholds selected by the user
    • Compensation algorithm to easily adjust the blood parameters according to those of the Hospital ABL

Safety Information

Heart-Lung Machine with Integrated Essenz Perfusion System

The Essenz Heart-Lung Machine is  intended  to  perform,  control,  monitor  and  support  extracorporeal  blood  circulation replacing  the  mechanical pumping  function  of  the  heart,  monitoring  and  regulating  physiologic parameters  during  procedures  requiring extracorporeal circulation. 

US: Essenz HLM is intended to be used during cardiopulmonary bypass for procedures lasting six (6) hours or less. Essenz ILBM is indicated for supplementary, in-line monitoring of the extracorporeal arterial oxygen partial pressure, venous oxygen saturation, venous hematocrit/hemoglobin, and arterial and venous temperature during cardiopulmonary bypass procedures up to six hours.

Essenz Patient Monitor

The Essenz Patient Monitor software is a modularly structured software program package that is exclusively used with LivaNova heart-lung machines. The system allows detailed recording of perfusion data during cardiopulmonary bypass procedures as well as the processing and evaluation of this data. The data may be recorded automatically or entered manually. The LivaNova Perfusion System Monitor is a panel PC intended to be exclusively used with LivaNova heart lung machines as a base and user interface for the Essenz Patient Monitor software. 

CONTRAINDICATIONS: No contraindications are  known  if  the  devices are  used  for  the  purpose  described  and  in  accordance  with  the  stated  operating conditions. Do not use the devices for any purpose other than indicated. 

WARNINGS: The devices must be used in accordance with the instructions for use provided.  For a complete listing of warnings please refer to the Instructions for Use. Medical intervention and therapeutic procedure must not be based solely on the Essenz Patient Monitor perfusion records (reports). 

PRECAUTIONS: Federal law (U.S.A.) restricts these devices to sale by or on the order of a physician. For a complete listing of precautions/cautions please refer to the Instructions for Use. The devices should be used by qualified and skilled personnel, able to follow the indications and instructions for use contained in  the  information  provided  by  the  manufacturer.

Essenz In-Line Blood Monitor and B-Capta Blood Gas Monitor are clinically equivalent in terms of safety and performance as they have the same technology and intended use.  Not approved in all geographies, consult your labeling. Please visit the LivaNova website  to  receive  instructions  for  use  containing  full  prescribing information including indications, contraindications, warnings, precautions and adverse.
