O2 delivery vs. PaO2. Definition. Oxygen delivery is defined as the amount of oxygen delivered to the capillaries per minute. It is calculated by the following formula: DO2=CO x CaO2 (mL/min/m2) So oxygen delivery is dependent on cardiac output as well as the arterial oxygen content.

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. This process can be conceptualized as three steps: oxygenation, oxygen delivery, and oxygen consumption. In this topic review, oxygen delivery and consumption are reviewed.

Peripheral oxygen delivery. Definition. Components of Oxygen in Blood. Oxygen delivery to the periphery depends on the oxygen content of blood and tissue blood flow. The oxygen content of blood has two components: oxygen bound to hemoglobin and oxygen dissolved in plasma. Oxygen bound to hemoglobin is generally the much greater contributor to ...

Oxygen Delivery - DO 2. The prime function of the circulation is to deliver oxygen and nutrients to the tissues and to remove waste products from them. If we know the cardiac output and the patient's haemoglobin level and oxygen saturation, then we can calculate one further critical value in hemodynamics - the oxygen delivery to the body or DO2.

Typical FIO 2 delivery settings are 24, 28, 31, 35 and 40% oxygen. The Venturi mask is often used when the clinician has a concern about CO 2 retention: A Venturi mask mixes oxygen with room air, creating high-flow enriched oxygen of a settable concentration. It provides an accurate and constant FIO 2. Second-Line Options: Face Tent/Shield

Indications for oxygen delivery . Where considering the application of oxygen therapy it is essential to perform a thorough clinical assessment of the child. Transient, self-correcting desaturations that have no other physiological correlates (eg. Tachycardia, cyanosis) may …

The Oxygenation Index Predicts outcomes, especially in pediatric patients by helping to determine need for ECMO. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis.

The arterial oxygen content equation: CaO2 = (1.34 * Hb * SaO2) + (0.0031 * PaO2). The normal oxygen combining capacity is 1.39 mls/gram, however due to abnormal forms of hemoglobin such as carboxyhemoglobin and methemoglobin this value is reduced to 1.34 mls/gram.
