Non-invasive detection of a femoral-to-radial arterial pressure gradient in intensive care patients with vasoactive agents

Abstract

Key messages A significant radial-to-femoral pressure gradient occurs in nearly one-fifth of patients in ICU. Repeated non-invasive assessment of the radial-to-brachial pressure gradient was significantly correlated with the invasive radio-femoral arterial pressure gradient.
