Book Synopsis Skin Temperature Feedback Optimizes Microclimate Cooling by :
Download or read book Skin Temperature Feedback Optimizes Microclimate Cooling written by and published by . This book was released on 2007 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel pulsed cooling paradigm (PCakin) integrating mean skin temperature (Tsk) feedback was compared with constant cooling (CC) or time-activated pulsed cooling (PC). Methods: Eight males exercised while wearing personal protective equipment (PPE) in a warm, dry environment (dry bulb temperature: 30C; dew-point temperature: 11C in each of the tests. Treadmill exercise was performed(~225 w 1 m-2) for 80 min. A liquid cooling garment (LCG) covered 72% of the body surface aera. Core temperature (Tc), local skin temperatures, heart rate, inlet and outlet LCG perfusate temperatures, flow, and electrical power to the LCG and metabolic rate were measured during exercise. At 75 min of exercise Tsk was higher (33.9 +/- 0.5 C) or CC(32.0 +/-0.6 C) and PC> CC. The changes in Tc and heart rate during the tests were not different. Tc at 75 min was not different among the cooling paradigms (37.6 +/- 0.3C in PCskin, 37.6 +/-0.2 C in PC and 37.6 +/-0.2 C in CC). Heart rate averaged 124 + 10 bpm in PCskin, 120 +/- 9bpm in PC and 117 +/- 9 bpm in CC. Total body insulation (C. W1. m-2) was significantly reduced in PCskin (0.020 +/- 0.003) and PC (0.024 +/- 0.004) from CC (0.029 +/- 0.004). Electrical power in PCskin was reduced by 46 % from CC and by 28% from PC. Real-time Tsk feedback to control cooling optimized LCG efficacy and reduced electrical power for cooling without significantly changing cardiovascular strain in exercising men wearing PPE.
Book Synopsis Thermal Comfort and Sensation in Men Wearing a Cooling System Controlled by Skin Temperature by :
Download or read book Thermal Comfort and Sensation in Men Wearing a Cooling System Controlled by Skin Temperature written by and published by . This book was released on 2007 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was done to determine whether thermal comfort (TC), thermal sensation (TS), and subjective factors gauging environmental stress were negatively affected with different cooling methods in men exercising in chemical protective clothing. Background: Previous studies have reported that intermittent regional cooling improved the efficacy of cooling as compared with constant cooling (CC), but no studies have addressed whether there is any improvement in thermal comfort. Methods: Eight male volunteers exercised at moderate work intensity (425 W) in three microclimate cooling tests. The circulating fluid in the cooling garment was provided during exercise to the head (6% body surface area [BSA]), torso (22% BSA), and thighs (44% BSA) and manipulated under three methods: (a) CC, (b) pulsed cooling (PC), and (c) PC activated by mean skin temperature (Tsk) control (PCskin). TC and TS ratings were recorded every 20 min during the 80-min test. Results: TC and TS ratings were not different for PC skin and CC; thus the participants perceived PCskin as being similar to CC. TS were significantly warmer with PC than with PCskin and CC (p

Book Synopsis Human Thermal Environments by : Ken Parsons
Download or read book Human Thermal Environments written by Ken Parsons and published by CRC Press. This book was released on 2007-03-22 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our responses to our thermal environment have a considerable effect on our performance and behavior, not least in the realm of work. There has been considerable scientific investigation of these responses and formal methods have been developed for environmental evaluation and design. In recent years these have been developed to the extent that detailed national and international standards of practice have now become feasible. This new edition of Ken Parson's definitive text brings us back up to date. He covers hot, moderate and cold environments, and defines these in terms of six basic parameters: air temperature, radiate temperature, humidity, air velocity, clothing worn, and the person's activity. There is a focus on the principles and practice of human response, which incorporates psychology, physiology and environmental physics with applied ergonomics. Water requirements, computer modeling and computer-aided design are brought in, as are current standards. Special populations, such as the aged or disabled and specialist environments such as those found in vehicles are also considered. This book continues to be the standard text for the design of environments for humans to live and work safely, comfortably and effectively, and for the design of materials which help the same people cope with their environments.

Book Synopsis Practical Applications of Fiberoptics in Critical Care Monitoring by : Frank R. Lewis
Download or read book Practical Applications of Fiberoptics in Critical Care Monitoring written by Frank R. Lewis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stimulating and provocative work with fiberoptic technology is reported in this volume. Invasive fiberoptic reflectometry has only been used up to now for monitoring intravascular oxygen saturation. These contributions examine how this technique can be clinically applied to measure other parameters in the critically ill patient. Methodological aspects are discussed, but the main focus is on clinical value and application. The authors look at measurements that can be evaluated using a flowdirected fiberoptic pulmonary artery catheter and an arterial fiberoptic thermodulution catheter. These measurements deal with oxygen saturation, intrathoracic and total blood volume, indocyanine green dye liver function, and extravascular lung water. Considering the advanced state of the technology and the innovative physiologic concepts presented here, this book lays the foundation for a new, integrated monitoring system of cardiopulmonary physiology.
