Cardiac monitoring to integrate in your monitor

The qCO OEM board is a solution designed to be integrated in a multiparametric monitor.

It includes the software to calculate Cardiac Output (CO), stroke volume (SV) and Heart Rate Variability (HRV) amongst others

The parameters are calculated from an impedance signal. 

The aim is to guide medical staff to detemine the cardiac output of the patient when monitoring the thoraxic blood flow.


Cardiac output

Stroke volume (SV)

Heart rate (HR)

Energy in the High Frequency (HF) band




Impedance curve

Signal Quality Index (SQI)

Pre-ejection Period (PEP)

Acceleration Index- Intropic State Index (ISI)

Left ventricular ejection time (LVET)

Thoracic fluid content (TFC)

Velocity Index- Ejection phase contractility index (EPCI)

Amount of blood pumped by the heart through the circulatory system in one minute.

Amount of blood ejected by the left ventricle of the heart in one contraction.

Heart rate is the number of heart rate beats per minute.

Energy in the 0.15-0.4 Hz frequency band is related with the Parasympathetic Nervous System (PNS) activity. Therefore, HF components increase when the heartrate increases.

Reports the short-term variations of PR intervals and is used to observe the influence of the PNS on the cardiovascular system.

Standard deviation of successive differences of the RR intervals.

Standard deviation of differences between consecutibr N-N intervals.

Graphic representation of the impedance.

It represents the quality of the collected signal.

Is the time during which the left ventricle contracts with the cardiac valves closed.

ISI reflects the maximum acceleration of blood flow in the aorta, which is an accurate marker of the inotropic state. 

Is the period of blood flow across the aortic valve.

Is an indicator of total fluid volume, both intracellular and extracellular, measured noninvasively impedanceusing cardiography.

EPCI is calulated form the peak velocity of blood flow in the aorta and indicated the maximum myocardial contractility during systole.
