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.

Jan 21, 2016 · The equation usually used to describe the rate of oxygen delivery is as follows: This equation will not be applicable when levels of dys-hemoglobins (e.g. metHb, carboxyHb, etc) are high. A better formula to describe DO2, taking into account only the concentration of effective Hb would be: Example: ceHb = 150g/L; Wt = 70 Kg; PaO2 = 100; SO2 = 100%

Delivered Oxygen (DO2) DELIVERED OXYGEN (DO 2 ) Whilst global delivered oxygen is an important principal to be considered as part of cardiovascular management, the various causes of a reduced global oxygen delivery (haemorrhage, anaemia, hypoxia) can result in …

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.

Oxygen Delivery. Therefore, oxygen delivery can be calculated: DO2 = CaO2 x CO. Oxygen Content. Oxygen content can be calculated as: CO2 = (1.39 x Hb x O2Sat/100) + (0.003 x PO2) Oxygen Consumption. Oxygen consumption can be calculated by the Fick principle as the difference between arterial and venous oxygen content: VO2 = CO x (CaO2 – CvO2)

Apr 09, 2019 · global oxygen delivery (DO2) is the total amount of oxygen delivered to the tissues per minute, irrespective of the distribution of blood flow oxygen consumption (VO2) is the total amount of oxygen removed from the blood due to tissue oxidative metabolism per minute Under resting conditions with normal distribution...

Oxygen Delivery. DO2: the Rate of Oxygen Tranport in the Arterial Blood * it is the product of Cardiac Output & Arterial Oxygen Content. DO2 = Q x CaO2. Cardiac Ouput (Q) can be “indexed” to body surface area. Normal C.I. : 2.5 - 3.5 L/min-m2. By using a factor of 10, we can convert vol % to ml/s .

The formula for calculating Oxygen Delivery (DO2) Cardiac Output (CO) x Oxygen Content (CaO2) Which two parameters represent the form in which O2 is carried in the blood? PO2 & SO2. Which factor has the greatest effect on arterial blood oxygen content (CaO2)? Hemoglobin Level (Hb)

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.

The haemodynamic perturbations associated with heart surgery may also compromise cerebral oxygen delivery (DO2) and could compound maturational and genetic risks. A recent study proposed a role for diagnostic group and circulatory arrest in infants undergoing arch surgery as associated with new white matter brain injury in the CHS population [ 5 ].Author: J. Trent Magruder, Narutoshi Hibino, Sarah Collica, Huaitao Zhang, H. Lynn Harness, Eugenie S. Heitm...
