Ventilation Modes

Synchronizing the Heart and Lungs during CPR


The new CCSV (Chest Compression Synchronized Ventilation) ventilation mode from WEINMANN Emergency is revolutionizing resuscitation.

We have many years of experience in the field of emergency and transport ventilation and take part in many scientific research projects. The result has been an innovation in resuscitation ventilation technology: CCSV.

In CCSV mode, a mechanical breath is initiated in sync with each chest compression. This means no gas volume escapes from the lungs and the pressure in the lungs provides support during the chest compression. A frequency tachometer helps the user to maintain an optimum compression frequency. An advantage of CCSV is that the ventilation mode can be used with mechanical chest compression devices. 


Advantages of CCSV

  • Automatic detection of chest compressions

  • Uninterrupted chest compressions

  • Can be used with mechanical chest compression devices

  • Easy to integrate into the standard resuscitation procedure

  • Improved arterial pressure

  • Improved gas exchange

  • Improved blood circulation

Resuscitation with CCSV


In Comparison to Conventional Ventilation during Resuscitation

Conventional ventilation at 30:2: During chest compressions, the heart and the pulmonary vessels in the thorax are compressed, which also results in air escaping from the surrounding lungs, causing a decrease in pressure.

Ventilation using CCSV: During the compression phase in CCSV mode, the mechanical breaths are performed in sync with the chest compression (manual or mechanical). As a result, no air can escape from the thorax. The intrathoracic pressure increases.

Advantages include increased arterial pressure, increased blood circulation, and improved gas exchange. The decompression phase switches to expiration and air escapes from the lungs. At the same time, the intrathoracic pressure decreases and the venous return flow to the heart can occur without any obstruction.

A "real" ventilation mode for use during CPR was hardly available before.
