Blood Gases — Arterial and Venous
Prior to commencing any discussion of the way in which anaesthesia and surgery can affect pulmonary function it is of value to first discuss the physicochemical basis of oxygen transport. The transport and exchange of oxygen and carbon dioxide causes changes in blood, and acid-base status and blood gas values are a reflection of these changes. Normal values of these parameters for arterial and venous blood are shown in table 4.1.1.
