AI Technical Summary

Problems solved by technology

Therefore, the skill level and acumen of the practitioner performing this scan greatly affects and limits the reliability and reproducibility of cardiac and / or hemodynamic parameters
Additionally, current echocardiography cannot and does not provide the same cardiac and / or hemodynamic parameters as those provided by invasive methods due to limitations imposed by the practitioner's skill level, therefore Maintains the need for invasive and minimally invasive procedures
Therefore, some cardiac and / or hemodynamic parameters are not available by non-invasive methods

[0162] Example 1: Determining Diastolic Pressure in the Aorta

[0163]The preceding examples are for illustrative purposes only and do not limit the application to the descriptions or calculations as set forth in the description.

[0164] Can be based, for example, on ultrasound and Doppler scans of a fixed area near the upper torso of the subject (e.g., a fixed scan area near the chest of the subject as shown and described herein above in FIGS. 1-8 ). combination to non-invasively determine the diastolic pressure of the aorta. Optionally, the following determinations are performed for individual cardiac cycles measured with Doppler ultrasound targeting at least one vessel of interest, such as the aorta or pulmonary artery, near the fixed scan region.

[0165] In stage 900, the cross-sectional area of ​​the vessel is determined for each subsection 806(i) based on the vessel radius determined according to the method described above, and based on Equation 1 below:

Abstract

The present disclosure relates to an ultrasound device, system and a method for determination of cardiac and / or hemodynamic parameters, and in particular, to such a system, and method in which the cardiac and / or hemodynamic parameters are determined in a non-invasive manner that is both automatic and autonomous and, therefore, does not depend on ultrasound imagery and / or a skilled caregiver analysis thereof.

Description

technical field [0001] The present disclosure relates to an ultrasound system, device and method for determining cardiac and / or hemodynamic parameters, and in particular to such a system, device and method in which non-invasive or microscopic Cardiac and / or hemodynamic parameters can be determined invasively. Background technique [0002] Cardiac monitoring is required for obtaining essential cardiac and hemodynamic parameters in monitoring and / or treating patients. Such cardiac monitoring can be achieved by different techniques of different levels of invasiveness (eg, invasive, minimally invasive, and non-invasive). For example, angiography, vascular imaging, cardiac catheterization, right heart catheterization, left heart catheterization may consider invasive or minimally invasive cardiac procedures. Alternatively, ultrasound based techniques such as echocardiography may be considered, a non-invasive method for determining available cardiac and / or hemodynamic parameters....
