Arterio-Venous Difference. This is the difference between the oxygen content of the arterial blood arriving at the muscles and the venous blood leaving the muscles. At rest the arterio-venous difference is low as not much oxygen is required by the muscles. ... Gas exchange and oxygen delivery influence performance in sporting activities.
Blood Gas Test: Purpose, Procedure, and Side Effects
Explain the difference in values between arterial and venous blood gas samples when taken from various locations in the body. List three possible complications of arterial punctures. Describe the appropriate assessment that should be done prior to drawing an arterial sample.

P gas = P atm x % of gas . State the approx. percentages of N2, O2, CO2, and water in atmospheric air (Table 17-2). 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.

Please send blood for a venous blood gas if no A-line and a blood culture if ordered by the surgeon. Most acute case are started with a baseline arterial blood gas and PRN throughout the case related to volume and blood product infusions. Please flush and leave in old lines until the end of the bigger cases.

Arterial line and cuff blood pressure (BP) measurements should not be compared, but rather accurate measurements, accurate technique, and appropriate trending. BP cuff should be appropriately sized and level with the heart. Arterial line pressure monitoring system should be assessed for optimal dynamic response (square wave test) and level.

An arterial blood gas demonstrates a pO2 = 56 and a pCO2 = 44. 2. 50 year old man with a 65 pack/year smoking history and a cough. His chest x-ray shows a diffuse reticulonodular pattern. 3. 36 year old man with muscular dystrophy. He is presently wheelchair bound and an arterial blood gas demonstrates a pO2 = 60 and a pCO2 = 52.

CaO2 is the arterial oxygen content. CvO2 is the mixed venous oxygen content. For example, consider the following conditions, an adult with ARDS is attached to a life-support ventilator, [Hgb] = 9 g /dl and the alveolar partial pressure of oxygen (PAO2) = 300 mm Hg (FIO2 = 0.50). Blood gas data: PaO2 = 65 mm Hg SaO2 = 91 %
