Filter by:Study design: A cross-over single-blinded treatment design will be used. Participants will undergo 4 different conditions: (1) low air flow and 23°C, (2) low air flow and 35°C, (3) high air flow and 23°C, and (4) high air flow and 35°C. Participants will be blinded to the air quality level; however, it is not possible to blind them to the temperature condition, as they will be able to perceive it as different. Study population: The population consists of healthy young and middle-aged adults of both sexes between 18 and 40 years. Intervention (if applicable): Each participant undergoes 4 conditions in randomized order. Two conditions consist of poor air quality defined as 3,000 ppm carbon dioxide and 23°C or 35°C temperature, respectively.
Low-intervention clinical trial. The thermal and hemodynamic effects of different cryotherapy devices are evaluated. This study is included in the doctoral thesis of the principal investigator. Investigators: Principal Investigator: Julio Alberto Mateos Arroyo (RN, MSc, PhD student) Directors: Ignacio Zaragoza García (RN, PhD), Ismael Ortuño Soriano (RN, PhD), Paloma Posada Moreno (PhD). Setting: Faculty of Nursing, Physiotherapy and Podiatry of the Universidad Complutense de Madrid. The three interventions to be evaluated are: - Applying crushed ice. - Apply frozen peas. - Apply comparator. Hypothesis: There are differences in the reduction of temperature, dimensions of the internal lumen of the radial artery and blood flow inside it depending on the different modalities of cryotherapy (crushed ice or bag of frozen peas) applied in the anatomical area of the wrist, point of arterial puncture for blood gas analysis. Main objective: To analyze the effect of 3 cryotherapy devices on the radial artery area. Secondary objectives - To analyze the thermal behavior of the superficial tissue under study according to the cryotherapy device used. - To analyze the differences in the radial artery caliber before and after the application of cold in the different experimental modalities under study. - To analyze the differences in radial artery blood flow before and after the application of cold in the different experimental modalities under study. - To identify the safety pattern of the use of the different cryotherapy devices (adverse events). Design: Randomized controlled clinical trial. This is a crossover clinical trial in which all participants will receive all interventions and will be randomized in the order in which they receive them. Population: Adults with a good general state of health, who specifically do not have factors that could affect their thermoregulation or vascular pathologies. Main variables: - Skin surface temperature. - Radial artery size. - Radial artery blood flow.
The VERDICT-2 verification study will examine the accuracy of the Cloud DX Vitaliti Continuous Vital Signs Monitor (Model: CVSM-1A) in an ambulatory context with healthy participants. The objective is to determine the accuracy of continuous non-invasive vital signs metrics including respiration, pulse rate, oxyhemoglobin saturation (SpO2), core temperature, heart rate, and cNIBP against standard comparator devices guided by consensus standards.
Objetive: To analyze the thermal effects of the types of liners used in the manufacture of the foot orthoses, as well as to establish the thermal differences among them. Design: Quantitative, experimental, longitudinal and prospective study. Subjects: 47 individuals selected randomly, over 20 years of age Methods: 4 types of liner were studied: natural skin, synthetic leather, perforated E.V.A and E.V.A. without perforation.
Abdominal computed tomographic (CT) is an important prognostic tool with regard to the detection of oncological, infectious and other abdominal disorders. The total iodine load (TIL) is regarded as a decisive factor in the opacification of parenchymal structures. The EICAR trial demonstrated that injection with high flow rates of prewarmed contrast media (CM) was safe and patients did not experience any pain, stress of discomfort during injection. Flow rates as high as 8.8 ml/s were injected without any discomfort. All concentrations used (e.g. 240, 300 and 370 mg I/ml) in this study were prewarmed. According to the recent recommendations (ESUR guidelines 10.0) it should be considered to warm iodine-based CM before administration. The hypothesis is that although using CM at room temperature (~23°C [~73°F]) might result in lower attenuation of the liver parenchyma than would be achieved using CM pre-warmed to body temperature, diagnostic image quality, patient safety and comfort will not be compromised by not pre-warming CM in this setting. According to the guidelines, it is regarded as best clinical practice to pre-warm CM. Surprisingly, these recommendations are merely based on a hypothetical assumption. In the literature, there are no studies evaluating this topic and it has never been clearly shown to result in a better patient comfort. For this reason, many clinics do not pre-warm their CM in daily clinical routine. Only one study evaluated subjective comfort in hysterosalpingography (HSG), in which CM is injected in to the cavity of the uterus. This study found that prewarmed CM alleviates the pain and decreased the incidence of vasovagal episodes during HSG. To the best of our knowledge, no study showed that prewarmed CM in CT resulted in higher patient comfort, in comparison to CM at room temperature (20° C). Up till now, all CM in the department is prewarmed. In case this study does not show a difference in patient comfort, prewarming the CM can be stopped, resulting in a considerable simplified workflow. The hypothesis is that usage of CM at room temperature (20° C) might result in a decreased level of patient comfort in abdominal CT, in comparison to pre-heated (37° C) CM, with no significant difference in diagnostic attenuation of the liver parenchyma between groups.
Core temperature should be monitored under general anesthesia. Recently developed 3M Spoton skin temeprature which is applied on temporal artery is correlated with core temperature measure by esophageal prove in several studies. Conventional skin temperature over carotid artery is also correlated with core temperature in several studies. The purpose of this study is comparing 3 methods of temperature monitoring. First, conventional core temperature measure by esophageal stethoscope. Second, 3M Spoton applying on temporal artery. Third, 3M Spoton applying on carotid artery
Different techniques of cryotherapy application present divergent responses. The objective was to establish differences between methods of application of ankle cryotherapy on skin surface temperature (TSP), agility and balance. The sample consisted of 20 healthy and active young men, 10 men and 10 women, with 21.4 (1.9) years. Initially, all performed the Modified Star Excursion Balance Test, Side Hop Test, and TSP collection of the lateral ankle region by digital thermography. After that, the application of the cryotherapy techniques - ice pack (PG), cold water immersion (LAI) and cryotherapy + compression by Game Ready® (CCGR), all for 20 minutes (') was randomized. The tests and TSP were reassessed in the immediate post-10'', 20'' and 30 'post. After three and six days, the other application forms were reassessed. Thus, the participants were randomly assigned to the three forms of cryotherapy.
One-lung ventilation interrupts oxygenation. The effect of heated humidifed breathing circuit on arterial oxygenation during one-lung ventilation has not been investigated. The investigators will investigate the effect of the heated humidifed breathing circuit on oxygenation during one-lung ventilation in patients undergoing thoracoscopic surgery.
This research was designed with partners to determine differences in temperature exposures in urban and rural communities in Alabama. The investigators hypothesized that significant differences in temperature exposure exist between urban and rural settings. Time spent outdoors has been previously positively associated with greater physical activity. Built environment components in urban versus rural environments and ambient temperatures experienced during the summer may pose barriers to time spent outdoors. Persons with Type II Diabetes Mellitus may find it more difficult to overcome temperature barriers due to reduced thermoregulation capacity. This analysis will result in a more precise picture of temperature exposure as well as behavioral factors that may mediate exposure.
Purpose The purpose of this feasibility study is to assess the accuracy and precision of the Temp-Traq thermometer for monitoring body temperature in adult patients under three conditions (hypothermia, normothermia, and hyperthermia).
