Peripheral oxygen delivery - Open Anesthesia

    https://www.openanesthesia.org/peripheral_oxygen_delivery/
    Using the dissociation curve and the equations above it is possible to calculate oxygen delivery and consumption. Under normal conditions, the oxygen tension of arterial blood is 95 mmHg (oxygen tension at the pulmonary capillaries is 104 mmHg, but pulmonary capillary blood then mixes with bronchial blood to reach an arterial oxygen tension of 95 mmHg), and is fully saturated.

How to Calculate Oxygen Amount According to Liter Flow ...

    Jul 27, 2017 · The flow meter should be set between 5 and 12 liters. The amount of oxygen delivered will be 40 to 60 percent. The flow meter should never be set less than 5 liters with this type of mask. Observe that a partial rebreather oxygen mask will deliver 35 to 60 percent of oxygen.

The USCOM and Hemodynamics - Oxygen Delivery

    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 Consumption Calculator - Medscape

    The Oxygen Consumption calculator determines a patient s VO2. The parameters used in the calculator include VExp, FIO2, FEO2.

O2 delivery vs. PaO2 - Open Anesthesia

    https://www.openanesthesia.org/o2_delivery_vs-_pao2/
    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.

REFERENCES - UpToDate

    https://www.uptodate.com/contents/oxygen-delivery-and-consumption
    In dyshemoglobinemias, the oxygen content is calculated with the same equation, although the saturations (and therefore the oxygen content) will be different for a specific PaO 2 [1]. Normal CaO 2 is approximately 20 mL O 2 /dL.

Oxygenation and Oxygen Therapy - PEDSCCM.org

    Oxygenation and Oxygen Therapy Michael Billow, D.O. The delivery of oxygen to all body tissues is the essence of critical care. Patients in respiratory distress/failure come easily to mind as the ones t hat require oxygen therapy as their initial therapeutic agent . However, all patients in the PICU may require oxygen during their disease course.

Arterial Oxygen Content (CaO2) Equation • RespCalc

    https://www.respcalc.com/arterial-oxygen-content/
    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.
