Abstract:
Pulse oximetry and capnography are widely used in clinical practice. They provide quick and noninvasive methods to estimate arterial oxygen saturation and carbon dioxide tension in different situations including emergency departments, intensive care units, and during procedures. This article reviews the principles of surgery, accuracy, limitations, and clinical applications of these instruments.
