Reliability of minimally trained operator's left ventricular outflow tract velocity-time integral measurement guided by artificial intelligence: protocol for a multicentre randomised controlled trial.

ABSTRACT:

Introduction

Stroke volume is a major determinant of tissue perfusion and, therefore, a key parameter to monitor in patients with haemodynamic instability and hypoperfusion. Left ventricular outflow tract (LVOT) velocity-time integral (VTI) measurement using pulsed-wave Doppler is widely used as an estimation of stroke volume and should be a competence required for every intensive care unit (ICU) physician. Artificial intelligence (AI) applied to ultrasound facilitates the acquisition of adequate images. The aim of the present study is to evaluate the interchangeability of LVOT VTI measurements obtained by minimally trained operators and expert physicians, both guided by AI.

Methods and analysis

This is a prospective multicentre randomised controlled trial. ICU patients in w
