Download Development and Evaluation of a Non-invasive Core Temperature Measurement System Book in PDF, ePub and Kindle
Core body temperature is an important physiological parameter used to identify whether a patient displays a normal, hypothermic, or hyperthermic state. It is routinely monitored during cardiac surgeries and general anesthesia. Currently, the most effective methods for measuring core body temperature are also the most invasive. While select devices have been designed to enable surface recording of internal temperature, none have been implemented in U.S.-based hospitals. The objective of this study was to create a noninvasive core temperature sensor and evaluate its potential of becoming a widely used clinical tool. In tissue phantom and human-based experiments, the prototype performed effectively and posed no safety risk. Provided the prototype can be successfully translated into a more streamlined medical device, it stands to become a staple in operating rooms around the nation.

Download Development of a Rapid, Noninvasive Core Temperature Measurement Device. Phase 1 Book in PDF, ePub and Kindle
The rapid, noninvasive measurement of core temperature in humans is desireable since both elevated core temperature (hyperthermia) and depressed core temperature, including oral and rectal thermometry, are unacceptable for field core estimation because of both physical and cultural problems. A rapid, noninvasive means of determining core temperature would be beneficial for in field management of combat casualties, as well as in peace-time evaluations of military materiel and physical workload assessments. In this Phase I SBIR effort, we have identified a new approach to rapidly and noninvasively measuring core temperature. We have established a relationship between exhaled air temperature, effective ambient temperature, and core temperature. In this relationship, the effective ambient temperature is the ambient air temperature corrected for wind velocity (wind chill), humidity, and air density. The results of our Phase I experiments indicate, that it is feasible to determine core temperature can be determined within 0.5 C of the temperature measured by an ingestible thermometry pill.

Download Physiology and Pathophysiology of Temperature Regulation Book in PDF, ePub and Kindle
This is a user-friendly monograph designed for medical students as well as graduate students and postdoctoral trainees in medicine and other health-related sciences who need a comprehensive overview of thermoregulation. It presents the bases of the modern concepts in thermal physiology and pathophysiology, bringing together the disciplines encompassed by this highly integrative field ? physiology, anatomy, biophysics, molecular and cellular biology, pharmacology, neuroscience, pathology, medicine, and others ? into a clear and concise form that can be read comfortably in a relatively short time. This text was conceived by the Commission on Thermal Physiology of the International Union of Physiological Sciences in response to its concern over the inadequate and outdated coverage of this topic in traditional textbooks. The membership of this Commission comprises international experts in each of the subfields of thermal physiology, with extensive research and teaching experience in their respective specialties. They are the authors of the chapters of this indispendable textbook.

Download Noninvasive Measurement of Core Temperature. Phase 1 Book in PDF, ePub and Kindle
Topical Testing proposes the development of a noninvasive device to monitor core temperature by sampling the maximal temperature of the respiratory air during expiration. Phase I development used a fast rise-time thermocouple to monitor the temperature of the expired air of an anesthetized animal model and investigate which parameters most greatly affect the expired air temperature at various stages of hypothermia. The Phase I goal of testing a working prototype has been achieved in which the critical parameters that influence the expired air temperature have been determined and controlled such that under most experimental conditions the error in estimation of core temperature is less than 1 C over a range of hypothermic temperatures. The Phase II goal will be development of a portable unit suitable to measure core temperature under field conditions. The proposed system will enhance the ability of the military to operate in low temperature environments by being able to monitor whether their troops are becoming hypothermic. It will be able to monitor temperature quickly in a noninvasive manner without the removal of clothing.

Download Thermoreception and Temperature Regulation Book in PDF, ePub and Kindle
As indicated in the Preface, the contributions to this volume are based upon the papers presented at the symposium on Thermoreceptors and Temperature Regula tion held in July 1988 at the Institute of Physiology of the University of Marburg (Federal Republic of Germany) to celebrate and commemorate the life and achievements of HERBERT HENSEL, who directed that Institute from 1955 until his death in 1983, and whose most notable and significant contributions to thermo physiology were in the areas of the properties and characteristics of thermo sensors, mammalian thermoregulation more generally, and the psychophysiology of ther mal sensation. All the papers in this volume deal, to a greater or lesser extent, with these discernibly different but closely allied aspects of mammalian physiology. The editors have sought to achieve cohesion, flow, and balance both in the contributed articles and in their order of presentation, without either large gaps or redundancies in the coverage of the recent advances in the understanding of thermoreceptors and thermoregulation. At the same time we have sought to avoid such a degree of editorial control as to destroy the individuality of the contributions, and the judgements upon which they were based. We have also sought to look both backwards and forwards, and to include some legitimate extension of the con sideration of thermosensitivity and thermoregulation into such areas as climatic adaptation and fever. Hence the "greater or lesser" of the closeness of this series of papers to HERBERT HENSEL'S scientific interests.

The principal aim of this study was to evaluate current literature on noninvasive methods and instruments on core temperature (body's temperature in deep tissue, i.e., heart). A specific goal is a conceptual design for a device to measure core temperature through chemical defense clothing. This report reviews temperature sensing devices, infrared.

Download Non-invasive Measurement of the Internal Temperature of Heat-generating Bodies Book in PDF, ePub and Kindle
While the surface temperature of a heat-generating solid body can be measured using a variety of methods, there is a scarcity of techniques that exist for non-invasively measuring the temperature inside the solid body. Internal temperature measurement is very desirable as mere measurement of surface temperature gives no indication of the internal temperature. The highest temperature, usually located at the core of the body, dictates system performance and safety. For example, Li-ion cells provide good energy storage and conversion characteristics, but unfortunately suffer from safety problems related to overheating due to insufficient heat removal during operation. The following thesis presents a technique to non-invasively measure the core temperature of a heat generating solid body for both steady state and transient cases, utilizing the theoretical relationship between the core and surface temperatures of the body. This method is experimentally validated by determining the core temperature of various heat generating cylindrical bodies - a thermal test cell and a Li-ion cell - using infrared temperature measurement on the surface, and comparing with measurements from embedded thermocouples within each cell. There is excellent agreement throughout the heat generation period between the predicted core temperature and measurements from the embedded thermocouple. These measurements demonstrate an accurate, non-invasive measurement method for real-time, core temperature monitoring. This thesis also investigates thermal performance of a Li-ion cell with a heat pipe inserted into the core. It is shown that active cooling of the protruding tip of the heat pipe results in maximum thermal benefit, which is shown to reduce the core temperature to as low as, or even lower than the surface temperature. This work contributes towards fundamental thermal metrology, and toward effective thermal management techniques for future Li-ion cell manufacturer designs, with possible applications in a wide variety of engineering systems.
