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 …

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 …

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.

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 …

Apr 23, 2024 · Inspired oxygen from the environment moves across the alveolar-capillary membrane into the blood. Most of the oxygen binds to hemoglobin in red blood cells, although …

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

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 …

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 …

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.
