NURS 303 Study Guide - Final Guide: Carbon Monoxide Poisoning, Cardiac Output, Autonomic Nervous System
Document Summary
There are things we can do as nurses to meet oxygen demand. There are three key areas were oxygen: ventilation, perfusion, diffusion. The use of oxygen in that process is called oxygen consumption. Right side of heart gets unoxygenated blood, goes to lungs, right side of heart, rest of body, lets oxygen go, comes back to venous system. You can do arteriosus and venous blood gases. We measure lactic acid to see if we have oxygenation: high levels in the blood then we think anaerobic (cid:373)eta(cid:271)olis(cid:373) is (cid:449)hat"s happe(cid:374)i(cid:374)g i(cid:374) the (cid:271)od(cid:455). Different ways we can tell the body is using oxygen. If you know that when you have aerobic metabolism. The cells are doing krebs cycle they are going to produce carbon dioxide water and 36 molecules of atp. They are going to need to exhale carbon dioxide. Whe(cid:374) the (cid:271)od(cid:455) does(cid:374)"t oxygenate efficiently, the body only produces very small amount of energy (lactic acid pathway) anaerobic metabolism.
