Gas Monitoring and Pulse Oximetry presents an extensive examination of the ventilation of the patient''s lungs. It discusses the administration of oxygen and inhalation of anaesthetics of patients. It addresses the methods of oxygen and carbon dioxide monitoring. Some of the topics covered in the book are the introduction to the use of capnogram; definition of oxygraphy and anesthetigraphy; mechanism of pulse oximetry; solubility of gases or vapors in water, blood, and tissue; description of anaesthesia machine with circle breathing system; and malfunction of valves and carbon dioxide absorber. The definitions and description of Mapleson breathing systems are fully covered. An in-depth account of the Jackson-Rees system is provided. The mechanism of Bain system, Lack system, and Magill system are completely presented. A chapter is devoted to description of titration of depth of anesthesia. Another section focuses on the analysis of the concentration effect, diffusion hypoxia, and cardiogenic oscillations. The book can provide useful information to clinicians, doctors, students, and researchers.

Systolic time intervals (STI), known for a long time, were revived in the early 1960s by Arnold Weissler. The first important papers came from him; they eval- uated STI measurements in larger populations, established norms, and compared STI measurements with other invasive methods. Since then, several hundred ex- cellent papers have appeared using and evaluating STI measurements for myo- cardial function studies. These have appeared in prominent cardiologic journals throughout the world as well as in the anesthesiologic and pediatric medical literature. When consent of subjects to medical experimentation became a prominent and necessary issue, the noninvasiveness of investigative methods in medicine, wher- ever possible, resolved the issue. Noninvasive measurements of STI proved to be an excellent monitoring parameter of cardiac function during anesthesia, and anesthesiologists wished to learn more from the long experience of cardiologists with STI. An organizing committee of List, Gravenstein, and Spodick was accordingly formed. Invitations were issued for an international conference on STI.With more than 40 clinical researchers using STI, it was, of course, difficult to hear them all within two days. A generous sponsor, the AVL Company, Graz-Schaffhausen, made possible the International Conference at Graz. Publication of the proceedings of the Confer- ence became feasible with help from Boehringer-Mannheim.
