Before we get into the different types of oxygen delivery systems, we need to go over a few key terms. First of all, you will hear systems referred to as low-flow and high-flow . Low-flow systems (like the trusty nasal cannula) deliver oxygen at a rate that is less than the amount of air that the patient can inhale or exhale in one minute (called “minute ventilation.”)

The cardiac index, systemic-vascular-resistance index, left ventricular stroke-work index, and oxygen delivery and consumption were calculated with the use of standard formulas.Author: Michelle A. Hayes, Andrew C. Timmins, Ernest Yau, Mark Palazzo, Charles J. Hinds, David Watson

respiratory system the group of specialized organs whose specific function is to provide for the transfer of oxygen from the air to the blood and of waste carbon dioxide from the blood to the air. The organs of the system include the nose, the pharynx, the larynx, the trachea, the bronchi, and the lungs.

Most of the oxygen binds to hemoglobin in red blood cells, although a small amount dissolves into the plasma. The oxygen is then transported from the lungs to the peripheral tissues, where it is removed from the blood and used to fuel aerobic cellular metabolism.

Sep 01, 2019 · Oxygen delivery systems. Oxygen delivery systems are categorised into low-flow and high-flow systems. Low-flow systems provide lower oxygen flow than the actual inspiratory flow (∼30 L·min −1). When the patient inspires, the oxygen is diluted with room air, and the degree of dilution depends on the inspiratory flows.Author: Georgia Hardavella, Ioannis Karampinis, Armin Frille, Katherina Sreter, Ilona Rousalova

Hypoxia: Low oxygen level at the tissues. Low flow: Low flow systems are specific devices that do not provide the patient's entire ventilatory requirements, room air is entrained with the oxygen, diluting the FiO 2. Minute ventilation: The total amount of gas moving into and out of the lungs per minute.

BACKGROUND: The physiologic goal of management after a Norwood procedure is to optimize systemic oxygen delivery, as indicated by oxygen excess factor (OEF). Factors were examined that might affect systemic oxygen delivery after the Norwood procedure with right ventricle-to-pulmonary artery (RV-PA) conduit as the pulmonary blood supply.Author: Yuji Naito, Mitsuru Aoki, Manabu Watanabe, Nobuyuki Ishibashi, Kouta Agematsu, Koichi Sughimoto, Tad...
