Arterial blood gas (ABG) analysis provide valuable information about a patient’s status ,the underlying cause of the imbalance, the body’s ability to regulate pH, & the patient’s overall oxygen status.1. Blood gas analysis is a basic and useful laboratory test for the critical care of patients. Arterial blood gas analysis is an essential ...

Blood Gas Test: Purpose, Procedure, and Side Effects
We may be presented (increasingly) with Venous Blood Gases . Differences are Subtle but important on Venous Gas: pO2 should be about 40mmHg (i.e. about the same as CO2) pH is about 0.05 lower on the Venous Gas compared with Arterial . CO2 is about 6mmHg higher on the Venous Gas . Bicarbonate is about 2 lower on the Venous Gas

The difference in O2 content between the alveolar and venous blood in the tissue will increase. C. Increases in cardiac output. In a normal individual, cardiac output can be increased by pumping more blood with each ventricular contraction (stroke volume) or by raising the heart rate.

List the normal alveolar, arterial, and mixed venous blood gas values for PO2, PCO2, SaO2, and pH and describe the mechanisms accounting for these values. Draw a normal spirogram labeling the four lung volumes and four capacities. List the volumes that comprise each of the four capacities.

Note that the normal blood Pco2 ranges between the limits of 40 mm Hg in arterial blood and 45 mm Hg in venous blood, which is a very narrow range. Note also that the normal concentration of carbon dioxide in the blood in all its different forms is about 50 volumes percent, but only 4 volumes per cent of this is exchanged during normal transport of carbon dioxide from the tissues to the lungs.

Central venous/mixed venous oxygen content CmvO2= 0.0031 x PmvO2+ 1.38 x Hb x SmvO2. CmvO2 is the amount of oxygen content returning to the heart. Normal CmvO2 is 15 mL/100 mL blood (vol%). Systemic oxygen extraction ratio (OER) OER = C(a – v)O2/CaO2. The amount of O2 taken out of the blood by the tissues is the systemic OER.
