Cardiac Cycle Efficiency - CCE

 

CCE describes the cardiocirculatory performance in terms of energy expenditure. This parameter represents the ratio of the power released by the ventricle and the power dissipated by the cardio-vascular system.

This is a significant index of the effort carried out by the heart to preserve the haemodynamic equilibrium and function in physiological and pathological conditions.

Besides assessing CO, MostCare® has shown the capability to define a new parameter for continuous haemodynamic monitoring, i.e. Cardiac Cycle Efficiency (CCE), and its changes over time. This parameter describes the cardiac performance in terms of the ratio work performed/energetic expenditure.

Therefore, CCE reflects the energetic expenditure required by the cardiovascular system to maintain the hemodynamic balance.

It is possible to assess the correlation between different energetic expenditures and CCE, expressing the ability of the cardiovascular system to maintain homeostasis at different energetic levels. CCE hence physically represents the ratio between the shape of the pressure wave that patients should ideally have and that actually detected during the examined cardiac cycle. This gives CCE a potential prognostic value, which needs to be assessed further.

 

What does it represent: 

Haemodynamic performed work with the relative energy expenditure.

 

How is it calculate:  

Ratio between an ideal cardiac cycle and the real one.

 

Normal Range:    

+1 to -1
