Abstract

The invention relates to determining a representation of cardiac output in a patient. Provided are a method and a system for monitoring a cardiac output using a single device inserted into a Central Venous Catheter (CVC) or Peripheral Inserted Central Catheters (PICC) line. In an embodiment, the device contains an elongated body that fits the lumen of a Central Venous Cava or Peripheral Inserted Central Catheters line and has an ultrasound transducer at the tip. By operating the device such that the velocity in both the Superior Vena Cava and Inferior Vena Cava can be sampled continuously theCO is monitored.

Description

technical field

[0001] The present invention relates to systems, methods and software products for determining a representation of cardiac output in a patient. Background technique

[0002] Cardiac output (CO) measurement is an important tool in monitoring a patient's hemodynamic status during surgery and during the patient's stay in the Intensive Care Unit (ICU). Cardiac output is the volume of blood pumped by the heart in a given amount of time. Since the blood circulation is a closed system, this can mean the volume of blood pumped by the left ventricle into the aorta, and likewise the volume of blood pumped by the right ventricle into the pulmonary artery, or into the right atrium (venous return) or the volume of blood in the left atrium.

[0003] In vitro ultrasound cannot determine CO with sufficient accuracy. Intravascular measurements are required, but there are serious risks involving prolonged intravascular blood flow measurements in the aorta. The pulmonary ar...
