Environmental Factors Affecting the Performance of Infrared CO2 Analyzer and the Estimation of Alveolar CO2 Tension by Pei Chin Tang Pdf

Theoretical equations were derived from known physico-chemical laws to determine the effects of room temperature and barometric pressure on the performance of the infrared type of CO2 analyzer. They were first tested experimentally and then against empirical equations derived from the Godart nomogram. These equations were found to be valid and useful in the estimation of the fractional concentration of CO2 of gas mixtures under various environmental conditions. Minimal gas temperature recorded with a thermistor probe at the inlet of the analyzer was used to estimate the water vapor pressure of gas samples in the analyzer chamber. This method was experimentally tested to be valid in estimating CO2 fractional concentrations of heated wet gas mixtures. It was used to estimate the alveolar CO2 tension of human subjects with various end-tidal sampling methods. Methods used by others with this type of analyzer were discussed. (Author).

Autonomic Responses to Vestibular Stimulation by Pei Chin Tang,Bo E. Gernandt Pdf

Decerebrate, paralyzed cats were used to determine some autonomic effects of vestibular stimulation and to establish through which peripheral links this vestibulofugal activity was transmitted. Vestibular stimulation increased both rate and depth of respiration, as demonstrated by phrenic and recurrent laryngeal nerve recording, and a marked elevation in blood pressure accompanied this effect. When the strength of stimulation was reduced and the evoked respiratory effect weak or questionable, the systemic blood pressure declined. Vestibular stimulation elicited strong responses from the neck vagus nerve, but this vestibulo-vagal activity was found to be conducted exclusively in the recurrent laryngeal nerve and not in the vagus nerve proper. Only the sympathetic portion of the autonomic system responded to vestibular stimulation, thus providing vestibular impulses a channel for reaching different effector organs. The responses obtained from the neck sympathetic nerve were analyzed and their characteristics described. (Author).

Capnography by J. S. Gravenstein,Michael B. Jaffe,Nikolaus Gravenstein,David A. Paulus Pdf

In recent years capnography has gained a foothold in the medical field and is fast becoming a standard of care in anaesthesiology and critical care medicine. In addition, newer applications have emerged which have expanded the utility of capnographs in a number of medical disciplines. This new edition of the definitive text on capnography reviews every aspect of this valuable diagnostic technique. An introductory section summarises the basic physiology of carbon dioxide generation and transport in the body. A technical section describes how the instruments work, and a comprehensive clinical section reviews the use of capnography to diagnose a wide range of clinical disorders. Edited by the world experts in the technique, and with over 40 specialist contributors, Capnography, second edition, is the most comprehensive review available on the application of capnography in health care.
