Mar 26, 2017 · The arterial oxygen delivery (DO2) equation is undeniably one of the most essential physiologic principles. DO 2 is comprised of two variables: Cardiac output (CO): This is the product …

Table of Contents Oxygen Delivery (DO2) Oxygen Consumption (VO2) and Oxygen Extraction Ratio (O2ER) Evaluating Oxygenation

Initially, as metabolic demand (VO2) increases, or DO2 diminishes, O2ER rises to maintain aerobic metabolism and consumption remains independent of delivery. However, at a point called critical …

Jan 31, 2024 · Normal DO2 is approximately 600 ml/min/m2 and normal VO2 approximately 120ml/min/m2 with a DO2/VO2 ratio of 5:1. This redundancy in delivery is imperative for our ability to …

Low Oxygen Delivery as a Predictor of Acute Kidney Injury during Cardiopulmonary Bypass. J Extra Corpor Technol. 2017 Dec;49(4):224-230. PMID: 29302112; PMCID: PMC5737422.

Mar 28, 2025 · Understanding DO2 (oxygen delivery) is essential for assessing patient oxygenation status, particularly in critical care settings. This guide explores the science behind DO2 calculations, …

Determines the amount of oxygen delivered to the capillaries per minute based on arterial oxygen content and cardiac output.

This article gives examples of the very precise compensation for CaO2 change in the form of sustained tissue specific DO2:VO2 ratios (corresponding with tissue specific oxygen extraction, E = VO2/DO2).

Sep 26, 2025 · Do2, or Oxygen Delivery (DO2), is a term used in medicine to refer to the amount of oxygen that is being delivered to the tissues in the body. It is calculated by multiplying the cardiac …

At the heart of effective perfusion lies the concept of oxygen delivery (DO2) and its index (DO2I), pivotal metrics that guide the assessment and management of perfusion adequacy.
