For decades, ventilation with continuous chest compressions has presented a challenge in CPR. This is because in addition to the need to maintain both the circulation of blood and perfusion, blood requires the best possible oxygenation.

This is hard to implement, especially with significantly reduced cardiac output. The largely non-standard techniques which have been in use up to now have a risk of less than optimal ventilation because of complex settings and thus the possibility of operating errors.

This is where Chest Compression Synchronised Ventilation (CCSV) comes in: Simple to operate and perfectly integrated in the resuscitation sequence, MEDUMAT Standard² in CCSV mode ensures optimal oxygenation and decarboxylation of blood during CPR!

How CCSV works

In conventional ventilation, the heart and the pulmonary vessels in the thorax are compressed during chest compressions, but the rise in intrathoracic pressure causes air to escape from the lungs, inhibiting the effect of pressure buildup and thus reducing cardiac output.

In ventilation during CPR under CCSV, a pressure-controlled mechanical breath is executed to synchronize with the chest compression performed, preventing any volume of gas escaping from the thorax; the increased pressure in the lungs ensures more vigorous compression of the heart during chest compressions. Cardiac output rises, ensuring improved gas exchange.

In the decompression phase, the device automatically switches to expiration to force air out of the lungs. At the same time, intrathoracic pressure drops and venous return to the heart proceeds unhindered.
